Aquatic Drones Tackle Local Waterway Pollution
By Furhana Husani, Director of Programs and Climate Initiatives – Waterfront Alliance
May 28, 2025
The New York and New Jersey waterways face significant environmental challenges, particularly from plastic pollution, harmful algal blooms, and the accumulation of biomass and other floating debris. These issues threaten marine ecosystems, biodiversity, human health, and economies reliant on clean water.
Plastic Pollution: A stark example of the problem is the estimate that 165 million pieces of plastic are floating in New York Harbor and nearby waters at any given time. This is part of a global issue where over 171 trillion pieces of plastic are in our oceans, projected to triple by 2040. This plastic debris, including tiny nurdles, breaks down into microplastics and nanoplastics, releasing chemicals that harm marine life and are considered among the world’s top environmental challenges.
Harmful Algal Blooms (HABs) and Biomass: HABs, caused by cyanobacteria that flourish due to excess nutrients like nitrogen and phosphorus from runoff, are increasingly prevalent. Last summer, over 500 confirmed harmful algal bloom conditions have been reported statewide in New York, affecting dozens of water bodies. HABs can cause health problems for humans and animals, from skin rashes to severe illnesses, leading to beach and swimming area closures for extended periods. Climate change is expected to exacerbate the frequency and intensity of these blooms.
Oil and Hydrocarbons: Incidental oil spills in areas like ports and marinas, often from land-based runoff or leisure craft, pose a risk to environmental health and can restrict activities like swimming, boating, and fishing.
These challenges underscore the urgent need for effective, environmentally sound methods for pollution removal and waterway restoration in densely populated coastal areas like New York and New Jersey.
RanMarine Technology, a cleantech company specializing in the design, manufacture, and sale of autonomous surface vessels (ASVs), also known as aquatic drones, is focusing its efforts on tackling these critical water pollution problems in New York and New Jersey waterways. Founded in Rotterdam, the Netherlands in 2016, RanMarine’s mission is to empower people, companies, and governments worldwide to restore marine and freshwater environments to their natural state using advanced, zero-emission technologies and data-driven approaches. ASVs are designed to clean the surfaces of waterways, including ports, harbors, marinas, rivers, estuaries, canal systems, lakes, and ponds.
RanMarine’s technology directly addresses these problems. The primary focus of their ASVs is the removal of harmful plastic pollutants, algae/biomass, and oils from water, as well as the treatment of HABs. Core products include:
WasteShark: An agile, efficient, and emission-free ASV that operates autonomously or via remote control to collect floating plastic debris and biomass.
MegaShark: A mid-sized vessel (tender boat duality) designed for high-volume waste collection of aquatic waste and biomass. Operated on-deck or via remote control.
BlueShark: Integrates WasteShark or MegaShark ASVs with a patented, chemical-free system that disrupts and eradicates cyanobacteria (the cause of HABs) in situ, reducing toxicity and nutrients without harming the ecosystem.
OilShark (in development): Designed as a first responder for incidental petrochemical and/or hydrocarbon spills in specific areas like ports and marinas.
RanMarine vessels are fully electric and operate with zero emissions, minimizing environmental disturbance and noise compared to traditional fossil-fuel methods.
Beyond collecting waste, RanMarine’s ASVs offer additional capabilities, often through partnerships with third parties. While operating, they can collect critical water quality data using various sensors, such as chlorophyll, pH levels, water temperature, salinity, turbidity, and dissolved oxygen. This data can be accessed in near real-time through the RanMarine Connect portal, aiding informed decision-making about water quality. The vessels can also be utilized for tasks like bathymetry in shallow nearshore areas, acoustic telemetry for tracking tagged fish, and visual mapping of the waterfront.
The application of RanMarine ASVs in the New York environment is evidenced through the successful deployment of a WasteShark at the Hudson River Park Trust (HRPT).
Vice President of Estuary & Education at the Hudson River Park Trust (HRPT), Carrie Roble said “Thanks to a grant from the NYS Department of Environmental Conservation, we were able to purchase our WasteShark, affectionally named “Gulp” by our community, approximately two years ago. Gulp now has her own little “shark-shed” at the Gansevoort Peninsula where our team periodically deploys her to help clean plastic hot spots along the bulkhead and park piers. Aside from collecting floating debris, she’s eye catching and an exciting educational tool, prompting conversations between Park users and our River Project team about our important work as park stewards.”
RanMarine’s strategy for deploying its technology, particularly in areas with significant need but limited direct funding like the vast New York and New Jersey shoreline, is heavily focused on innovative partnerships. This is achieved via multi-sector collaborations involving International Governmental Organizations (IGOs), Non-Governmental Organizations (NGOs), various tiers of government, technical partners, operational partners, and ultimately funders including but not limited to as grant makers, corporate sponsors, and environmentally conscious high-net-worth individuals.
A prime example of this approach is the recently launched “Adopt a Shark” initiative in New York City. This initiative will facilitate the deployment of RanMarine ASVs across multiple harbor sites to remove floating plastic debris and biomass and treat HABs in situ. This program will work to engage local communities and involve organizations specializing in the green-blue economy and workforce training.
Through this partnership strategy, RanMarine seeks to make its innovative technology accessible to the areas and organizations that need it most, facilitating crucial clean-up and restoration efforts across the vast and complex waterways of New York and New Jersey and raising awareness about the significant pollution problems they face.
RanMarine is currently seeking to connect with environmental stewards, community leaders, and potential sponsors and funding partners in the New York and New Jersey area who recognize the need for these capabilities in their local waterways and are interested in exploring collaborative deployment opportunities.

RanMarine’s speciality lies in creating waterborne robots, also known as Autonomous Surface Vehicles, that focus on cleaning floating pollution out of waterways, both inland and coastal. Founder and CEO Richard Hardiman was inspired to start the company after observing people using nets to fish rubbish from water. A firm believer in using technology to replace mundane tasks, Hardiman set out to address the inefficiency he saw: “I wanted to solve that inefficiency rather than a pollution problem.”
Trash Trapping Program rids Toronto Harbour of 175,000+ pieces of plastic in 2024
PortsToronto’s Trash Trapping Program has emerged as a beacon of environmental innovation, showcasing how technology and collaboration can effectively combat waterway pollution. Since its inception in 2019, the program has made significant strides in removing plastic debris and other contaminants from Toronto Harbour, preventing these pollutants from reaching Lake Ontario and beyond.
A Multifaceted Approach to Pollution Control
The Trash Trapping Program utilizes a combination of advanced technologies and manual efforts to address the pervasive issue of floating debris. Key tools include Seabins, WasteShark aquadrones, and LittaTrap catch basin filters. Seabins, essentially floating garbage bins, are deployed at strategic locations along Toronto’s waterfront to suck in trash from the water’s surface. WasteSharks, nicknamed “Ebb” and “Flow,” are remote-controlled aquadrones that skim the water for floating debris. Meanwhile, LittaTraps are installed in storm drains to capture plastics before they even enter the waterways.
Complementing these technologies is manual skimming, which involves physically removing large debris and invasive plants that accumulate microplastics. Together, these efforts have created a robust system for intercepting waste at multiple points along its journey to the lake.

Impressive Results
The program’s achievements speak volumes about its effectiveness. Between May and October 2024 alone, over 600 kilograms of anthropogenic debris—waste created by human activities—were removed from Toronto Harbour. This included more than 100,000 small pieces of plastic, such as bottle caps, foam fragments from food containers, cigarette butts, and even larger items like fatbergs. In earlier years, similar efforts removed tens of thousands of pieces of plastic annually, underscoring the program’s consistent impact.
Notably, the introduction of WasteSharks in 2023 proved particularly effective. In just three trials during their pilot phase, these aquadrones collected approximately 20 kilograms of marine debris. Combined with ongoing efforts by Seabins and other devices, the program has become a critical tool in reducing microplastics and other pollutants in Toronto’s waterways.
Research-Driven Innovation
A cornerstone of the Trash Trapping Program is its partnership with the University of Toronto Trash Team (U of T Trash Team). Researchers from the team meticulously analyse the materials collected by trash traps to identify sources and trends in pollution. This data-driven approach not only informs solutions-based research but also supports policy changes aimed at reducing waste at its source.
For instance, researchers have identified that much of the floating debris originates from stormwater run-off, industrial activities, and improperly managed waste bins near water edges. Insights like these have led to targeted community outreach programs designed to increase waste literacy and encourage better disposal practices.
Expanding Impact Beyond Toronto
The success of PortsToronto’s initiative has inspired similar programs across the Great Lakes region and beyond. As part of the International Trash Trapping Network led by Ocean Conservancy and U of T Trash Team, lessons learned from Toronto are being applied globally to combat plastic pollution in urban waterways.
Moreover, PortsToronto’s efforts align with broader strategies like the Toronto Inner Harbour Floatables Strategy. This collaborative framework brings together various stakeholders to reduce floating litter through innovative methods and strategic placement of trash traps.
Looking Ahead
As the program enters its seventh year in 2025, PortsToronto is set to expand its capabilities further. Plans include adding three new fixed trash-trapping devices to its existing fleet of seven Seabins and two WasteSharks. These additions will enhance coverage along Toronto’s waterfront and Outer Harbour Marina.
The continued success of this initiative underscores the importance of collective action in addressing environmental challenges. By combining cutting-edge technology with research-driven strategies and community engagement, PortsToronto is not only cleaning up local waterways but also setting a global example for sustainable urban water management.

WasteShark robot to clean Yorkshire canals and rivers
A robotic drone is being used to clean up the waterways in Leeds.
The cutting-edge technology has been developed in the Netherlands and is the first of its kind to be used in Yorkshire in the UK, according to the Leeds Waterfront group.
The robot swims along waterways and can scoop up to 500kg of waste from the surface through a wide mouth, hence it being named the Waste Shark.
The chairman of the Leeds Waterfront Group Paul Ellison said the aim was to “enhance the rivers” in the city, which were often “forgotten about and neglected”.
Mr Ellison said the robot was inspired by a whale shark.
“That has a big wide mouth which it opens to feed, in the same way waste gets caught inside its mouth,” he said.
The drone, called a WasteShark, is powered by electric motors and directed via a remote control from the riverside.
It is equipped with GPS, collision avoidance technology and a camera.
“Everyone wants to see action being taken, waste collects in certain areas in Leeds and there is an amazing amount of wildlife in the river now,” Mr Ellison said.
“We want to prevent any of that being digested by wildlife and also to prevent the rubbish, and to prevent it going further beyond the city and out into the sea.”
He said weekly data would be collected to show how much waste is being removed from the water.
It will also record the types of waste being collected.
The project is also the first use of the technology to be approved by the Canal and Rivers Trust.
Becca Dent, from the charity, said it was important to work in “new” and “innovative ways” to remove litter from the waterways.
“It can be quite challenging, unfortunately millions of pieces of litter end up in our waterways.
“We’ve got birds that live along here, otters, and water voles.
“I’ve seen a moorhen trying to make a nest out of a trolley and crisp packets, so it’s really good to see the waste removed.”
