Why water quality matters

What is the first thing that comes to mind when you hear the words Water Quality? We bet you think of your drinking water and whether or not it’s actually safe to drink. You might even think of a water filtration system that cleans your drinking water.

But water quality refers to more than just your drinking water.

Take rivers, for example. Testing the water quality in rivers allows us to know the biological factors that could be impacting aquatic life and ecosystems.

Why we must monitor our waters

Things like algae and phytoplankton have a huge influence on rivers since they can affect groundwater. Monitoring the rivers can help researchers predict, learn and determine the human impacts on these sensitive ecosystems. Measuring the water quality in these bodies of water can also determine if restoration projects need to be undertaken or simply to determine if the water quality meets environmental standards.

Algae and plankton

Algae are plant-like organisms found in rivers, lakes, ponds and oceans. And even in snow. They come in a variety of structures, from simple plankton to large seaweeds. Single-cell phytoplankton float on the water but can, at times, grow in colonies large enough to be seen. While they have plant-like abilities, they are not actually plants.

Phytoplankton falls into two classes, namely algae and cyanobacteria. Most freshwater phytoplankton is made up of green algae and cyanobacteria, (which is also known as blue-green algae), and is actually a type of bacteria. Cyanobacteria are literally the only bacteria that contain chlorophyll. (The bluish tint that you see in blue-green algae actually comes from their pigments called phycoerythrin and phycocyanin).

Seaweeds

Macroalgae (seaweeds), on the other hand, generally attach themselves to the ocean floor (except seaweeds like Sargassum that actually float on the surface of the water and do not attach to the floor bed).

Read our blog: Why we must tackle our Sargassum issue

When phytoplankton and macroalgae growth gets out of control, they can pose dangers to aquatic life. Monitoring these levels is therefore crucial to maintaining balance in the ecosystems where they live.

Dissolved oxygen

Another water quality test that is generally undertaken is dissolved oxygen levels. Dissolved oxygen basically refers to the amount of dissolved oxygen in the water that is available to aquatic life. Testing these levels is important because of its influence on the organisms living within that body of water. When these levels are too high or too low aquatic life can become affected, as can the water quality.

All forms of aquatic life depend on dissolved oxygen, including plants, fish, invertebrates and bacteria. Aquatic life that lives on the ocean floor or in deeper waters need less dissolved oxygen, while those living in shallow waters need more. It might surprise you to learn that organisms responsible for decomposing organic matter at the bottom of the ocean, such as bacteria and fungi, also use dissolved oxygen to help them do their work.

In a stable body of water with no stratification (a system or formation of layers), dissolved oxygen will remain at 100% air saturation. However, the deeper you go, the less dissolved oxygen you will find. This is primarily due to the fact that these deeper waters have not been in contact with air. The actual amount of dissolved oxygen will vary depending on things like water temperature, salinity and pressure.

But how exactly does low dissolved oxygen levels affect aquatic life?

Let’s take a closer look at salmon and trout which are cold-water fish. These fish will generally avoid waters where the dissolved oxygen levels are too low because low levels will cause them to die within a matter of days.

Furthermore, low levels of dissolved oxygen will not only delay the hatching of their eggs but will also impair their growth and lower their rate of survival. Carp, on the other hand, are slightly hardier and can survive and thrive in waters with lower dissolved oxygen levels. It goes without saying then that if dissolved oxygen levels in rivers and oceans drop too low, the fish in those regions will begin to die off.

Equally, if dissolved oxygen levels are too high, this also creates problems as supersaturated water can cause gas bubble disease in fish and invertebrates. Gas bubble disease in fish is the equivalent to “the bends” in scuba divers. Fish can easily die from gas bubble disease, and since they might not show symptoms, it makes it difficult for researchers to diagnose them.

Dead Zones

 A dead zone is an area of water where there is little to no dissolved oxygen. This usually occurs when there are too many nutrients like phosphorous and nitrogen in the water, causing blue-green algae overgrowth. Needless to say, aquatic life cannot survive in these zones which are usually found near heavy human populations. And humans are usually the cause of dead zones due to agricultural and industrial activities.

In developed countries, manure and fertilizers are the main culprits, while in developing countries untreated wastewater from sewage and industry are the culprits. Since these facilities are less regulated than in developed countries, wastewater is often dumped into rivers, lakes, creeks or the ocean.

According to National Geographic, scientists have identified 415 dead zones worldwide.

Water Quality testing has therefore become crucially important if we are to ensure that both our aquatic life and humans survive.

One such company that offers a combined solution to both water quality testing and clearing of pollution from bodies of water is RanMarine Technology.

Their WasteShark and DataShark collect data that is geotagged and timestamped to give an accurate picture of the water quality health within an ecosystem, thus allowing one to accurately monitor the quality of the water to help verify compliance with pollution regulations, identify potential contaminants early to minimize the impact on the environment and, basically, to make the water safe for everyone to enjoy.

It’s thanks to advances in water quality testing like these that we are able to enjoy clean drinking water and being able to swim safely in rivers and lakes

How Sharks Play a Vital Role in the Food Chain

Sharks have been portrayed as vicious killers and predators to be feared. This is in part thanks to the many Hollywood films dedicated to the fear genre. While the films might make for great entertainment, they have done little to promote sharks in a positive light.

While sharks are indeed scary-looking creatures, they are not as deadly and lethal as fear-mongers make them out to be. In fact, most sharks are pretty harmless and most people will never even encounter a shark in their lifetime.

Sharks have been roaming the oceans for more than 400 million years and their presence keeps the marine world in balance. They mature very slowly and breed few offspring, with the females reaching reproductive maturity at around 12 to 18 years of age. The exception to that is the Great White shark, who only reaches reproductive maturity at around 33 years.

How do Sharks balance the ocean’s ecosystem?

In the ocean, sharks are at the top of the food chain. Known as Apex Predators, they help keep fish populations from overpopulating, and they preserve marine biodiversity. Thanks to the sharks, slow and unhealthy fish are gobbled up, leaving room for the healthy fish to thrive. Not only does this contribute to an overall healthy marine ecosystem, it also creates abundant fish for humans to consume.
Algae are much-needed plants in the marine ecosystem, essentially supplying marine life with energy through their process of photosynthesis. If algae-eating fish numbers were to decline, the entire ecosystem would be in big trouble. With an overproduction of algae, the reef system would become overwhelmed and would not be able to recover from bleaching and other reef disturbances. Guess who keeps these algae-eating fish numbers under control? You guessed it.

How do sharks benefit humans?

Not only do they keep the marine ecosystem balanced, but they provide humans with incredible healing inspiration too. Marine scientists have been puzzled for years as to why sharks rarely become ill as other marine species do. This has led them to examine shark tissues that appear to have anticoagulant and antibacterial properties that can be used to treat certain medical conditions in humans. Scientists have now designed a coating used in hospitals to treat bacterial infections. Sharklet, is the world’s first technology to inhibit bacterial growth through its pattern alone. It draws inspiration from the shape and pattern of the dermal denticles of shark skin and contains no toxins or chemicals.

How do sharks help to control climate change?

We all know that carbon contributes to climate change. By feeding on the dead matter at the bottom of the ocean, sharks actually help to move carbon through the ocean.

Sharks are about 10 – 15 percent carbon. If they are killed and removed from the ocean, they actually release that carbon into the atmosphere. If sharks are left to die naturally, they sink to the bottom of the ocean and their carbon is safely sequestered for millions of years.
If sharks were to completely disappear it would create a devastating chain reaction with far-reaching consequences to the human race. Our entire marine ecosystems would collapse and everything from coral reefs, food security, and climate change would be affected.

What is killing our sharks?

When fishermen run out of fish, which often happens in overfished areas, they have to literally cast their nets further and wider. Commercial fishing often employs the longlining method, meaning they cast lines with baited hooks attached at intervals by means of branch lines called snoods. This method easily snags non-targeted marine life like sharks (known as bycatch). That means that a large number of sharks are accidentally caught.

You might have heard about shark fin soup – a delicacy in China and Vietnam. Hunters catch sharks and literally slice off their dorsal fins, then throw them back into the ocean to sink to the bottom as the sharks are unable to swim without their dorsal fins. Sometimes their bodies are sold on to be harvested for making things like lubricants and leathers. The Hong Kong market alone handles more than 3000 tonnes of shark fins annually and the “best” fins sell for more than $400 each. Many of the sharks killed for their fins haven’t even reached reproductive age yet. A recent study on the genetic analysis of fins at the Hong Kong market revealed that about one-third of the fins actually belonged to threatened species.
Shark specialists estimate that between 73 million and 100 million sharks are killed for their fins each year. That equates to about 11,000 sharks killed every hour or 3 sharks every second.

How do sharks inspire us?

Whale Sharks are one of the largest creatures on earth, and probably the most docile of all sharks. Whale Sharks are cold-blooded, warm water fish and they live in temperate and tropical seas near the equator. They migrate incredible distances in search of food and are one of the ocean’s biggest binge eaters. They can weigh more than 30 tonnes and be larger than a city bus in length. But like all sharks, they are endangered.

RanMarine Technology created an aqua drone that was designed to clean waterways, canals, rivers, harbours, and ports by removing floating pollution and biomass. Their design was inspired by the Whale Shark and is aptly named WasteShark. The autonomous surface vessel (ASV) weighs 72 kgs and is 157 cm in length. WasteShark moves through the water at a maximum speed of 3 km/hr and literally gobbles up waste. Moreover, the ASV is able to measure and monitor the quality of water.

It collects data that is geotagged and timestamped to give an accurate picture of the water quality health within an ecosystem. This allows one to accurately monitor the quality of the water to help verify compliance with pollution regulations, identify potential contaminants early to minimize the impact on the environment, and make the water safe.

Sharks literally take care of the oceans and their rapidly declining populations are threatening our very existence on this planet. Without them, the entire seafood chain would collapse. Our very survival depends on sharks surviving and thriving.

How are you contributing to the decline or protection of these precious marine animals?

Reducing Harmful Green-Algae Blooms Is Crucial to Protecting Aquatic Life

Algae blooms are essential in maintaining a healthy body of water and a great deal of attention has been brought to them in the past number of years. This is because of the harmful impact they can have on the environment, human health, aquatic life and animals. Not all algae blooms are harmful. It is crucial to know which ones are so we can create strategies to ensure our environment and all the beings living on it are protected. Keeping our waters clean is ever more important. We use water for everything from cooking to drinking to cleaning and much more.

What is blue-green algae?

Blue-green algae is a kind of bacteria known as cyanobacteria. It is naturally occurring and a component found in freshwater environments. It’s considered crucial for maintaining a healthy body of water because it produces oxygen. Not to mention, it’s also a source of nutrition for particular marine animals. Responding to certain conditions, Blue-green algae could undergo a population explosion known as blooms.

These conditions involve slow or still-flowing water, warm days with lots of sun and high amounts of nutrients, in particular phosphorus and nitrogen. These blooms occur under natural conditions. Blue-green algal blooms can have an appearance similar to that of spilled green paint or pea soup and are not always uniform. They can sometimes be small and cover less of a lake with visible algae present. Blue-green algal blooms are also not always dense and large. When the cells break down, they create a swamp-like odour.

What’s the problem with algae blooms?

Areas where aquatic creatures are unable to survive due to low oxygen levels are known as dead zones. Generally dead zones are caused by substantial nutrient pollution. Primarily, they are an issue for lakes, bays and coastal water because they are provided with additional nutrients from upstream sources.

The additional phosphorus and nitrogen results in overgrowth of algae and this occurs in just a short period of time (algae blooms). They block sunlight and consume oxygen from the underwater plants. Once the algae finally dies, the oxygen within the water is consumed. Since the oxygen is widely reduced, this makes it very challenging for aquatic creatures to live.

The biggest dead zone within the United States, for example, is the Gulf of Mexico. It is roughly 6,500 square miles and occurs each summer. This is as a direct result of the nutrient pollution that occurs in the Mississippi River Basin.

Some of these algae blooms are known as harmful algal blooms. These blooms are considerably large and produce toxins or chemicals. They typically occur in reservoirs, ponds, bays, rivers, coastal waters and lakes.

Beyond the threats to water quality and aquatic life, algae blooms also have implications for humans, other animals and the environment. When they occur, they interfere with other uses of the water. This can impact human health and has implications for the economy and the planet. They impact water quality by creating unpleasant odours and tastes in addition to scum and discolouration.

It can also be toxic. In other words, contact with large amounts of blue-green algae can cause irritation to the skin and eyes. In serious situations, they can damage the human nervous system and liver. Exposure to blue-green algae blooms has been linked to the death of livestock, pets and wildlife.

As the bloom becomes less intense, decaying and dead algae can lower oxygen levels within the water. This has a direct effect on aquatic animals, causing them to experience stress or could even result in fatalities. During times of drought, algae blooms can severely degrade aquatic ecosystems.

Not all algae blooms are deemed harmful. Some examples of harmful algal blooms that pose implications for aquatic ecosystems, human health and the economy include red tides, cyanobacteria and blue-green algae.

What actions can I take to prevent being harmed by algae blooms?

There are a number of actions you can take to protect yourself from the impacts of green-blue algae blooms. Firstly, if you come into contact with this kind of algae, you should wash your skin thoroughly afterwards. In addition, you should steer clear from using untreated river or lake water for cooking, drinking or brushing your teeth. Many treatment steps are required to remove algae toxins. Therefore, a simple treatment will not cut it. The water could be contaminated and cause irritation to the skin. Another way to prevent yourself from being harmed by algae blooms is to not eat fish from these algae-laden waters.

Is there a way to get rid of harmful algae blooms?

There is no way to fully remove blue-green algae from lakes. This is because while they are harmful, they are an essential component of the overall algal community. Rather than thinking about ways to remove them, we need to think about how to control the frequency and intensity of harmful algae blooms. Controlling the water temperature is out of our means. Therefore, the best action we can take is to lower the number of nutrients that enter these waters. Lowering the nitrogen and phosphorus levels within man-made sources is one of the best ways to accomplish this. This reduction will not occur overnight, but taking this approach is the best long-term solution to lowering the intensity of frequency of these blooms.

A solution does exist

Toxic algae blooms are a global issue and they are accelerating at a frightening rate in our rivers, lakes, reservoirs and oceans. The results of these blooms in our waters can be extreme. They are wiping out aquatic life, threatening human and animal health and our planet. Not to mention, they are impacting local communities and industries like tourism and fishing. While there is no way to entirely eradicate these blooms, we can work to control them. There are actions we can take as individuals to protect our own health. Not to mention, there are also ways we can reduce the intensity and frequency of these blooms by reducing the phosphorus and nitrogen levels in man-made sources.

RanMarine Technology created the world’s first autonomous data harvesting surface vessel to be deployed commercially, known as DataShark. Focussing on collecting and collating water quality health data from waterways in any environment the DataShark is capable of multiple sensor configurations, real-time data logging with GPS tagging.

DataShark can be configured with different sensors to help monitor temperature, depth, dissolved oxygen, turbidity, blue-green algae, crude, refined oils and more. Any data you collect is immediately available for reporting and analysis through the WasteShark Data Portal.

Whether you run a smart city, water district or an organization, the DataShark helps ensure that data collection is quick and accurate ensuring our waters are safe for everyone.

A MEGA 3D-PRINTED EUROVISION TROPHY

The four-metre high 3D-printed Eurovision trophy made from recycled PET material retrieved from Rotterdam waters is a genuine eye-catcher with a sustainable green footprint. This trophy is a reflection of the city’s character, long driven by the port, innovation and collaboration.

The Rotterdam proving ground

With its rugged port buildings and superb views over the water, the Rotterdam Makers District is the ideal spot for an innovative manufacturing industry. This is where new technologies are thought out, tested and applied. An area still bristling with raw edges, offering the space for businesses and educational institutions to experiment, explore and work together on a clean and sustainable future for the port and the city.

The new technologies here are based upon digitalisation, robotics and continuous fibre additive manufacturing (CFAM), and on the application of new, sustainable energy and materials. All of this results in the Makers District being an exciting proving ground and showcase for the new economy, there for all to see.

Circular production of PET material
Young entrepreneur Wesley dos Santos is the founder of the circular water-recreation business iKapitein. Sailing on his eco-barge through the city of Rotterdam, you will become aware of the diversity that the city has to offer, ranging from historic Delfshaven to the legendary skyline. The electric eco-barge removes litter from the water as it sails along; as the vessel moves forward, its built-in litter-catching system retrieves plastic from the water. If you would prefer to be more active on the water, grab a water bike and pick litter from the water as you move about! Wesley’s mission is to see more electric boats with built-in litter-catchers and sustainable water bikes on the waters of Rotterdam. Active boating and biking, where fun, innovation, awareness and recycling come together.

The collected PET litter from Rotterdam waters is converted into printing material, which Royal 3D uses to create new products with a 3D printer. This is not just any 3D printer, it is a CFAM, purpose-built for Royal 3D by CEAD in Delft. CFAM stands for Continuous Fibre Additive Manufacturing, meaning that glass fibre is continuously added to the printing material. This produces a stronger, more rigid and consequently more sustainable end result. This material forms the basis of the giant Eurovision trophy and is fully recyclable, even if a print should go wrong.

RanMarine WasteShark

The future of the trophy
The giant trophy will be put up for auction after the Eurovision Song Contest and the proceeds will go to the Dutch company RanMarine, a Rotterdam-based business born out of a desire to improve the welfare of our world’s oceans and waterways.

Their water-cleaning WasteShark can play a significant role in helping to address the scourge of plastics, associated waste and biomass when deployed in appropriate environments. They have been specifically designed for use within ports, harbours, marinas and inland waterways.

They focus on helping to clear plastics and associated trash from waterways before they enter the ocean where their containment and collection becomes far more challenging and costly.

Looking to Nature’s Designs to Solve Human Made Problems

When a genius and an icon like Leonardo da Vinci looks to nature for inspiration in his designs and inventions, art and creativity, how could the rest of us even think about ignoring this wondrous three-billion-year history of evolution?

In his day, when Leonardo was roaming the countryside, strolling through the streets of Florence, or counting the branches on a tree, he embodied an intense curiosity about the natural world around him. It was a deeply embedded curiosita. Today we call it biomimicry.

Velcro is a much cited example of biomimicry (inspired by burdock burrs stuck in a dog’s fur), as is the flipper (inspired by ducks and their webbed feet), the submarine (whales), and Japan’s famous bullet train (the kingfisher). But none of these solutions actually do our environment any good.

Because when people look to nature to solve problems, shouldn’t nature herself benefit too?

We should all know by now that nature is in crisis. We’re facing food and water insecurity, melting ice caps, global warming from fossil fuels, deforestation, biodiversity loss, air pollution, and of course, plastic pollution. And that’s not even all of it.

But let’s look beyond the crisis of nature for a moment, and look to nature herself for the inspiration we need to solve the mess we’ve collectively made. As lovers of the ocean, we can’t help but dive under the waters for a closer peek at the plethora of magnificent creatures that live there as an example of extraordinary design.

The electric eel, for example, can produce enough electricity to light up to 10 light bulbs. Sea cucumbers clean the ocean (they eat anything that sticks to sand, take in the food, and then excrete the sand again, all nice and clean). Feather stars are almost walking plants that wave their ‘feathers’ around to move underwater. The blue dragon is a sea slug that floats upside down on the ocean waves. And basket stars, close relatives of starfish, use their many arms to create an intricate web to trap their prey.

And then of course, there’s the incredible fact that 76% of ocean creatures produce their own light. And still, we only know a tiny fraction of our ocean’s various species. New marine life is being discovered every day. How could we not be inspired to a da Vinci level of curiosity?

Biologist Frank Fish from West Chester University in Pennsylvania wins in biomimicry and sustainability for how he’s changing the way engineers think about aerodynamic design and inspiring the redesign of wind turbine blades that produce more energy more efficiently. And all this because Fish was captured by the unique design of humpback whales and their flipper bumps.

For EcoStp, their inspiration for zero power, zero chemicals, sewage treatment technology came from a cow’s own internal process. Nature’s genius empowered them to create a regenerative innovation that utilises the functional principles and strategies of microorganisms and the ecosystem found in a cow’s stomach. EcoStp’s patented technology treats sewage in a decentralised, self-sustainable way, without power, chemicals, or human intervention.

RanMarine’s waste-devouring WasteShark was inspired by the gentle and majestic giant of the ocean, the whale shark. A filter feeder, the whale shark swims with its mouth wide open, scooping up plankton and small fish as it moves slowly forward. And now its drone twin, the WasteShark, is also in our waters with its own wide-open mouth and voluminous belly, but its scooping up plastic pollution instead.

Richard Hardiman, CEO of RanMarine Technology, says it started at the V&A Harbour in Cape Town. Watching two people in a boat trying to battle plastic waste with nothing more than a pool net, he was struck by the futility of their efforts. Battling both tide and people’s inability to clean up after themselves.

‘When I later discovered this was standard practice in harbours all over the globe … and when I realised just how dire the marine plastic pollution crisis really is, I just knew I had to do better than that. We had to do better than that.’

The result is an autonomous aqua-drone that can collect up to 500kg of waste per day with a zero carbon footprint. It also harvests vital data about the health of the water. In fact, over 200 environmental sensors can be fitted onto one WasteShark, continuously reporting on vital facts to help us keep our waters healthy and protect the creatures living in it.

It’s a no brainer, when nature is our mentor, when nature is our inspiration, when we are truly connected, the sustainable solutions can be limitless.

The Health of our Waters and Innovations to Protect Them

If we had to ask ourselves if we were doing enough to protect our waters, we’d have to admit to some pretty hard truths. Because really, all it takes is one glance around the globe to see that we need to be doing a lot more to understand, measure, and manage our waters, and we need to be doing it now.

The toxic algae bloom, for example, is a global issue we’re facing on an alarming scale in our oceans, rivers, lakes, ponds, and reservoirs. Sludgy, smelly, and hazardous, when toxic algae bloom out of control and release toxins, the results can be devastating.

Harmful algae blooms (HAB) have been known to last up to 14 months, wiping out all kinds of marine life in their path, including dolphins, sea turtles, and other wildlife, posing potentially dangerous health impacts for local communities, and devastating industries such as fishing and tourism.

Read our blog: Reducing Harmful Green-Algae Blooms Is Crucial to Protecting Aquatic Life

But release a DataShark into your waters and you can learn everything you need to know to help you protect your precious water resources both now, and in the future. An innovation from award-winning RanMarine Technology, the DataShark is the world’s first data harvesting autonomous surface vessel (ASV) to be commercially deployed in the fight against pollution and scourges like algae blooms.

The DataShark shares its design inspiration with RanMarine’s game-changing WasteShark. Both modelled on Mother Nature’s own whale shark, RanMarine’s WasteShark scoops up marine waste, biomass, and plastic, while the DataShark collects and collates water quality health data from waterways in any environment.

Freshwater ecosystems in particular, require effective management in order to remain healthy and function properly. Freshwater is indispensable for life on our planet, supports the environment, society, recreation, and the economy, and yet it is increasingly under threat.

In addition to the growing demand of freshwater for human purposes, the effects of climate change are also exacerbating changes, manifesting in ever more frequent and severe extreme events and disasters such as drought and floods. This in turn undermines the ability of freshwater ecosystems to contribute to both climate change adaptation, and mitigation.

Whether it’s freshwater or saltwater environments, a large water body, or small, RanMarine’s DataShark is user-friendly and easily integrated into any work environment or field operation. It only takes a one-person team to operate this intelligent aqua-drone and capture GPS tagged data points. In fact, signing into RanMarine’s secure customer web-portal would allow you to operate and manage your drones from anywhere in the world.

With 10-hours of battery life, and a typical range of 10 km, the DataShark harvests data which is captured through the RanMarine Data portal, and reported in both graph and raw format in real-time – and stored for analysis. All data is geo-tagged and time stamped, giving an accurate picture of the water quality health within your ecosystem.

Each DataShark drone can be equipped with a variety of water health quality sensors and probes. Partnering with Eureka Water Probes, RanMarine has designed its drones to facilitate the data harvesting of numerous data points including temperature, pH, conductivity, optical DO, turbidity (with optional depth and ORP), nitrogen, and toxic algae (blue/green) levels – with many other vital options configurable on request.

And the options are vital, because even something as apparently simple as a change in water temperature can have a negative impact on ecosystems. The temperature of the water influences not just the biological activity and growth of aquatic life – life that cannot survive when temperatures rise or fall too far beyond the ideal range – but it also has an effect on the water chemistry itself. Generally, the higher the temperatures, the more the chemical reactions increase. Warm water also holds less dissolved oxygen than cool water, which means there may not be enough dissolved oxygen for various aquatic species to survive.

Another apparently simple yet vital data point is the pH level of your water. For example, heavy metals dissolve much easier in acidic water and can become more toxic as a result. But even the slightest change in pH can be detrimental to aquatic life. Just a small shift can affect the gills of fish and diving insects, the hatching success of fish eggs, as well as the amphibian populations. When the shift in pH is even greater, water with an extremely high or low pH can be deadly for fish and animals.

Changes in pH and temperature can also point to the growth of algae.

Richard Hardiman, CEO of RanMarine Technology says, ‘Especially in the 21st century, the monitoring of water quality has become imperative in order to measure the effectiveness of current water policies, to better protect human health as well as the overall environment and economy, and to prevent events such as fish deaths, the loss of recreational use of water bodies, and to, when necessary, plan restoration projects.’

And we now have some compelling technology to help us protect the waters across our planet. With RanMarine’s data-harvesting DataShark and its intelligent aqua-drone twin, the waste-devouring WasteShark, the company remains steadfast in its goal to empower humankind to restore the marine environment to its natural state.

Top 5 sustainability pioneers in Europe

The events of the past year have put many things in perspective – and have served to highlight the urgency of the climate crisis. Sustainable start-ups are attracting increased interest from ethically-motivated consumers, as the world looks towards a greener post-pandemic future.

The pandemic has prompted us to reconsider many aspects of our lives, from our working habits to how and where we spend our money. It has also served to heighten our awareness of environmental issues, as we begin to think of the world we would like to see post-pandemic. According to a survey by management consultancy company Accenture, 60 percent of consumers say that they have started making more environmentally friendly, sustainable or ethical purchases since the onset of the pandemic in 2020.

In the business world, too, sustainability has become a top priority over the course of the past year, with major firms such as Unilever and Google announcing significant green pledges over the course of 2020. Even amid the COVID-19 crunch, venture capital firms have been pouring money into sustainable, purpose-driven start-ups, suggesting that eco-friendly products and services may well be a key area of growth in the post-pandemic world. With that in mind, let’s take a look at five of Europe’s top sustainability pioneers.

1 – Oatly (Sweden)
The non-dairy milk market has been booming in recent years, and is predicted to reach revenues of over $38bn by 2024. This is good news indeed for Swedish oat milk-manufacturer Oatly, which has seen its sales soar as ethically-driven consumers seek alternatives to traditional dairy products. Founded in the 1990s, the company states its aim as: “to make it easy for people to turn what they eat and drink into moments of healthy joy, without recklessly taxing the planets’ resources in the process.” Boasting partnerships with major retailers such as Starbucks, the company is undoubtedly one of the most prominent names in the plant-based industry, and is now said to be seeking a valuation of close to $10bn as it prepares to go public on the US stock exchange.

2 – EO Charging (UK)
With many of the world’s workers giving up the daily commute in order to work from home in 2020, the pandemic has encouraged a reassessment of our transport usage. While global car sales fell by around a fifth during the pandemic, sales of electric vehicles rose by a remarkable 43 percent, showing an increased appetite for eco-friendly cars. As the demand for electric vehicles grows, the need for increased EV charging infrastructure is becoming ever more apparent. Based in the UK, EO Charging is one of Europe’s leading manufacturers of electric vehicle charging ports, having sold more than 30,000 charging points in over 30 countries in the five years since its launch. Working with high-profile partners such as Uber, Sainsbury’s and Ocado to facilitate a transition to EV, EO Charging was recently named among the Financial Times’ fastest growing companies in Europe.

3 – Cellugy (Denmark)
Plastic pollution is an area that has come into sharp focus over the course of the past 12 months, with discarded single-use masks becoming an all too common sight since the start of the pandemic. Based in Aarhus, Denmark, Cellugy is a pioneering biotech start-up that is committed to helping to bring an end to plastic pollution through the creation of alternative forms of packaging. Its innovative product, called EcoFLEXY, is a durable material designed for use in the packaging industry. Made from recycled food waste, the product is all-natural, fully recyclable and biodegradable. In a recent seed round, the company raised €2.38m from the European Innovation Council Accelerator, which will allow it to scale-up production of its EcoFLEXY product.

An unexpected side effect of the COVID-19 pandemic has been the unfortunate increase in marine litter pollution. Plastic gloves, single-use masks and other forms of PPE have been washing up on beaches across the globe, with this increase in plastic waste threatening the health of marine life the world over. Dutch drone technology firm RanMarine is the company behind the innovative WasteShark – a product designed to clear plastic and other waste from all manner of waterways. The device has a 10-hour ‘swimtime,’ and is able to clear 500kg of debris from the water each day – with users able to control the device remotely and monitor its progress in real time. The firm secured a Series-A investment in 2020, allowing it to scale-up its operations this year and beyond.

Autonomous vehicles playing a vital role in waste management

NOVEMBER 5, 2020

Autonomous vehicles helping in security and ensuring asset protection across public spaces and private organisations is something that we hear of every day. However, very little is known about these vehicles helping in managing waste and even less so of those that run underwater.

From the assessment of the size of a waste pile to the detection of its thermal heat, autonomous vehicles can collect data that are more detailed and insightful than ever. Unlike manned flights, they are a lot more affordable and can acquire equally detailed data. Thus, employing them rather than adopting traditional on-ground inspection method, can not only be cost-effective but time-saving as well, for waste management organisations. In addition to this, in many countries, they are being used to pick up garbage at public places and also identify industrial litterbugs that illegally dump factory wastes. The images and videos captured are used as evidences to take necessary actions against them.

While these are mainly the use-cases of aerial autonomous vehicles, when it comes to waste management, even those that run underwater play an important role. An ideal example is WasteShark by RanMarine Technology, a Netherlands-based tech start-up that specialises in the design and development of industrial autonomous surface vessels for ports, harbours and marine environments.Modelled on the Whale Shark, WasteShark is equipped for waste and data collection underwater, having a swim time of around 10 hours and is capable of cleaning over 500 kg debris a day. Having roped in a number of investors, one of which is the Luxembourg-based investment firm Boundary Holding founded by Rajat Khare, RanMarine has been able to achieve unparalleled feats in the clean-tech sector.

Trash-Eating Drones Are Taking on Water Pollution

An autonomous water drone lumbers around Ilfracombe Harbor on the North Devon Coast in Southwest England. Called WasteShark, the 5-by-3.5-feet catamaran-shaped “aquadrone” scoops up plastic, rubbish, and debris before the tide takes it out to sea.

Inspired by whale sharks that cruise around the water with their mouths open to suck in plankton and fish, WasteShark gobbles up over 1,000 pounds of waste that crosses its path daily. “We built it on the same principals as a whale shark. It is the size of an average coffee table and operates just like a robotic vacuum cleaner that goes around your room, sweeping the dust from your floors,” says Richard Hardiman, CEO of RanMarine Technology, the Netherlands-based startup that developed WasteShark.

England is not the only location deploying water drones to prevent plastic from entering the ocean and threatening marine life. Founded in 2016, RanMarine has used WasteSharks to help clean up the harbor waters in the United States, additional areas in the United Kingdom, the Netherlands, South Africa, India, Denmark, Sweden, the United Arab Emirates, and Australia. According to Hardiman, its customers include local and federal governments, port authorities, educational and commercial organizations.

He believes that the vessel is most effective at “waste chokeholds like harbors, rivers, and canals” because it can “enter hard-to-reach areas and easily navigate through water traffic to clean urban, rural, and industrial waterways.” Extending no deeper than a foot beneath the surface, the device glides through the water and its mouth-like opening in the front catches everything in its path. A metal-wire basket, located between its two hulls, filters out the water and collects solids that are brought back to the shore to be emptied, sorted, and recycled.

WasteShark can be steered manually via remote control or set up to swim autonomously; its collision-avoidance system employs remote-sensing technology called Lidar to spot obstacles, such as buoys and other crafts, and adjust its position accordingly.
