Robot Jellyfish Show Promise for Ocean Cleanup

Robot Jellyfish Show Promise for Ocean Cleanup

Where are we Now?

Many different negative outcomes have been observed due to reckless disregard for our environment and ecosystems. The main focus in the environmental movement has been on GHGs, reasonably so, as carbon accumulation in the atmosphere poses the largest existential risk for our species and all other animals on our planet.

However, plastic pollution and pollution, in general, have been and continue to be a large risk for many animals and living things across the globe, this fact being amplified in the ocean. Marine ecosystems are delicate; many plants and animals depend on specific conditions to survive and thrive.

As such, cleaning up our oceans and other marine ecosystems is paramount. While numerous technologies have been developed to combat plastic pollution in our water, many of them have their own risks associated with them.

Some machines are too loud, driving animals away from their natural habitats. At the same time, others are too damaging in their efforts to clean up pollution, destroying delicate plants and animals while clearing away plastic.

However, a new technology developed by scientists out of the Max Planck Institute for Intelligent Systems may be able to solve these problems with minimal impact of its own, and that revolves around imitating jellyfish.

 

How Does a Robot Jellyfish Work?

When jellyfish move in the water, what happens is by flapping their bodies, they create an upward current, moving objects and nutrients up to be consumed by them. This new robot jellyfish more or less does the same thing.

It works by using artificial muscles called HAZELs, which are oil-filled sacs covered by electrodes. When the electrodes receive a current, they discharge it to the surrounding negatively charged ocean water. This causes the oil sacs to get pushed back in forth, creating the flapping movement.

This mechanism is the main draw behind these robotic jellyfish, as by using these robots, they can pull the plastic out of delicate areas like coral reefs without ever touching the reef itself. Another benefit is that these robot jellyfish are almost completely noiseless, so their presence won’t disturb other animals.

In a report in Science Advances speaking on how their technology is different from existing technology, they said, ​​“Existing prototypes cannot interact with aquatic species gently in a noise-free manner while accomplishing diverse tasks.” These jellyfish robots, however, can, and that is where the promise of what they’re doing lies.

 

Moving forward.

While these small robot jellyfish are an exciting development in plastic cleaning tech, there are hurdles still to be overcome in their creation. The main one presenting itself is that, as of writing, they still require a wired connection for power, thus limiting their scope to areas where they can be plugged in. There are ongoing trials for battery packs, but so far cannot be controlled remotely.

However, that is a small issue that can be resolved quickly. It is an interesting concept to imagine cute little robot jellyfish cleaning our oceans, but it is, in all reality, much closer than we realize. The importance of realizing efficient and non-disturbing ways of cleaning our oceans is critical, as plastic pollution’s damage to ecosystems and species worldwide is innumerable.

While in some areas of the environmental movement, we can help the ongoing natural processes, like reforestation for carbon capture, in plastic pollution in marine environments, we must develop new tools to reverse the damage we have caused. What an interesting world to live in, where robot jellyfish could be a major factor.

Shark in the water: This robot can collect 21,000 plastic bottles in a day

Shark in the water: This robot can collect 21,000 plastic bottles in a day

 

Inspired by a whale shark’s wide mouth – which scoops up whatever is in front of it – Richard’s company Ran Marine created the WasteShark.

“I liken it to a Roomba for water. It’s an autonomous machine that scoops up pollution out of water on the surface level.”

“That pollution could be plastic or any debris or biomass like algae,” Richard adds.

Why is there a robot shark at Canary Wharf?

The Aqua Libra WasteShark was deployed in London’s Canary Wharf this week as part of a project to clean up the area and make it a healthier, more biodiverse environment.

Canary Wharf is a thriving financial district located on London’s River Thames. 120,000 people visit every day to work or shop there.

The Canary Wharf Group, which developed and manages the area, have done a lot to reduce single-use plastics. But the high footfall means it’s easy for coffee cups and lunch wrappers to end up in the water.

Currently, only 14 per cent of English rivers meet good ecological status. The country’s waterways are plagued by pollution from agriculture, sewage, roads and single-use plastics.

In fact, it is estimated that 8 million tonnes of plastic enter our oceans every year, much of it being swept from cities to the sea through rivers.

“The way we designed the WasteShark was that it was zero impact on the environment that it’s working in,” says Richard.

“You’ll see a lot of boats that go out and clean are normally diesel-powered or mechanically powered so there’s a bit of oil and pollution going back into the water while they’re cleaning,” he explains.

WasteShark is completely electric and is so quiet it doesn’t disturb wildlife, according to the Ran Marine CEO.

“Ducks and swans swim away from it. We’re not fast enough to catch fish. So it really is a low-impact solution to remove pollution out of the water.”

What can WasteShark do?

The WasteShark is battery-powered and travels up to 5km on one battery. That amounts to around 8-10 hours of cleaning time. A daily feed for the WasteShark is around 500kg of debris or the equivalent of guzzling roughly 21,000 plastic bottles.

Any rubbish collected in the robot’s belly is then brought back to shore, sorted and recycled or disposed of responsibly.

Whilst it’s filling up, the WasteShark also collects samples of the water.

“We’re collecting water quality data from all around the world and aggregating that [so we can see] what it looked like last week, last year. Is the water getting cleaner? Is it changing? Is there a potential algae bloom?” explains Richard.

“It’s kind of our dream to deploy these things around the world to clean up while we’re asleep, make a difference and hopefully make an impact on our environment.”

A Consumer’s Guide to Reducing Pollution

A Consumer’s Guide to Reducing Pollution

Consumers play a major role in creating pollution. By some estimates, household consumption is responsible for the majority of air and water pollution in the world.

But by being aware of how you use water, what you toss in the trash, how you drive and how you use energy around the home, you can take some simple steps to prevent a lot of pollution.

While you may think of pollution as a global problem, reducing pollution from your household can have more immediate benefits by improving your neighborhood’s environmental health.

 



How to Prevent Air Pollution

A 2015 study in the Journal of Industrial Ecology found consumers account for 60 percent of the world’s greenhouse gas emissions.

“If we change our consumption habits, this would have a drastic effect on our environmental footprint as well,” Diana Ivanova, one of the study’s authors, told Science Daily at the time.

Pollution prevention is often a matter of consumer choices. Products that are similar can have much different effects on the environment. The way you use products from your car to lawn care chemicals can significantly affect how much you contribute to air pollution.

 

The Car You Drive

In 2017, highway vehicles emitted 18.9 million tons of carbon monoxide, according to the U.S. Environmental Protection Agency.

Such emissions play a role in the creation of greenhouse gases, such as carbon dioxide and ozone, that warm the atmosphere. And breathing in higher levels of carbon monoxide decreases the amount of oxygen that reaches a person’s organs and tissues. For a person with heart disease, the health effects can mean a trip to the emergency room or a hospital stay.

Motor vehicles also produce hydrocarbons, nitrogen oxide and particulate matter that also contribute to air pollution.

But the way you drive and the vehicle you choose can cut back on not only emissions but also how much money you spend on gas.

Let’s say you travel 15,000 miles per year and the average cost of gas is $2.83 per gallon. You can save about $700 per year if you drive a car that gets 30 miles per gallon instead of one that gets 20 miles per gallon.

And you can potentially improve gas mileage by about 10 percent if you ditch aggressive driving habits that waste gas, such as speeding, accelerating rapidly and braking.

WHAT YOU CAN DO: Driving more efficiently or driving less can reduce the amount of air pollution you put in the air. Scheduling your multiple home deliveries so they arrive on the same day can reduce pollution from delivery trucks. And keeping your car in tune and its tires properly inflated will improve your gas mileage while reducing the pollution it puts out.

 

Household Products

Consumer products from kitchen cleaners to shampoos now account for as much air pollution in urban areas as all forms of transportation, according to a 2018 study in the journal Science.

Air pollution from cars, trucks and other types of transportation has been declining as the United States and other countries have passed stricter emission standards. But there hasn’t been the same kind of regulation of air pollution from household products like kitchen cleaners and personal care products.

These products contain volatile organic compounds, also called VOCs. Once these compounds escape into the atmosphere, they can create ozone or other air pollution.

When you burn fuel in your car, only about one one-thousandth of the VOCs in your gas or diesel ends up in the air. But products like cleaners, paints, hair spray and perfumes can pump a larger percentage of their chemical pollutants into the air as they evaporate. And these chemicals can also contribute to indoor air pollution in your home.

WHAT YOU CAN DO: Look for “Low VOC” in products’ labels and make sure containers are tightly sealed to reduce evaporation. Buy products with the EPA’s “Safer Choice” label. These are products that work as well as conventional products but are safer for human health and the environment, according to the agency. You can search for and compare products in the Safer Choice database.

Energy Use

Your household energy use may create twice as much greenhouse gas emissions as your car does in a year’s time. More than 63 percent of the electricity in the United States still comes from burning fossil fuels, according to the U.S. Department of Energy. Improving energy efficiency in your home can help reduce air pollution.

The typical household spends $2,000 a year on electricity. Using Energy Star products can save you 30 percent or about $575. At the same time, you’ll avoid putting an extra 5,500 pounds of greenhouse gases into the air.

WHAT ELSE YOU CAN DO: Something as simple as turning off the lights when you leave a room can make a huge difference. A 2014 study in the International Journal of Science and Research estimated excessive use of light wastes 2 million barrels of oil every day.

 

Lawn Care

Motors on lawn and garden equipment are not as clean as the engine in your car. They may be small, but they can pump a lot more pollution into the air. And simply pouring gasoline into their tanks before you crank them up can cause air pollution, too

Gasoline spills may seem small, but there can be millions every day. Spills contribute to smog and other kinds of air pollution.

WHAT YOU CAN DO: Using electric lawn mowers or using portable gas cans with automatic sealing and shut off features are two quick ways to make your lawn care greener.

 

 

Preventing Water Pollution

Polluted runoff and storm water is considered one of the greatest threats to clean water in the United States. In urban and suburban neighborhoods, storm water and melted snow can’t easily soak into the ground. The water runs into storm drains, taking oil, dirt, chemicals and lawn fertilizer directly into streams, lakes and rivers.

WHAT YOU CAN DO: Simple steps around the home make big a difference in reducing water pollution. Pick up pet waste, keep yard clippings out of storm drains and fix car leaks before the next big rain washes oil and other fluids into your local water supply.

 

Pesticide and Fertilizer Alternatives to Prevent Water Pollution

Using alternatives to toxic pesticides can reduce water pollution. Pesticides include consumer products like Roundup or other weed killers as well as insecticides. But there are natural alternatives.

WHAT YOU CAN DO: Plant native flowers, shrubs and trees that are resistant to pests and can attract pollinators and other beneficial insects. Install bird and bat houses in your yard to combat pesky bugs. A 2018 study in The Science of Nature estimated that globally, birds eat nearly a half trillion tons of insects a year.

Take a similar approach with fertilizers. Nutrients such as nitrates and phosphates in fertilizer can overstimulate water plants and algae. Phosphorus has been called “junk food for algae.” It fuels algae growth, which kills fish and other life in waterways.

WHAT YOU CAN DO: Hire a certified lawn care professional or carefully follow label directions. Too much fertilizer can damage plants and pollute groundwater. Leave grass clippings on the ground after you mow to create a free, slow-release fertilizer. The Peace Corps also offers instructions for making your own less-toxic pesticide alternatives from natural ingredients.

 

 

Reducing Landfill Waste

The U.S. Environmental Protection Agency estimated Americans threw away more than 260 million tons of solid waste in 2015. That came to 4.48 pounds of trash per person every day of the year. More than half of the waste ended up in landfills.

More than 91 million tons of solid waste were recycled and composted in 2015. Another 33 million tons were burned to generate energy.

Paper, food and yard trimmings accounted for more than 54 percent of all solid waste in American cities. In many cases, all three could have been either recycled or composted.

Landfills also contribute to air pollution. Organic material buried in landfills creates landfill gas as it decomposes. The gas is about half carbon dioxide and half methane, a powerful greenhouse gas that traps heat in the atmosphere.

Landfills are the third-largest source of human-related methane emissions in the United States. They produced about 14 percent of methane emissions in 2016.

WHAT YOU CAN DO: Compost organic waste such as food scraps and grass clippings to keep waste out of landfills and help your lawn or garden grow. Don’t just recycle paper, glass and cans; buy products made with recycled materials. And opt for reusable products from cloth mops to rechargeable batteries instead of disposables.

 

 

25 Things You Can Do to Reduce Pollution

Everyday activities can contribute to air, water or land pollution and you may not even realize it at the time. Here are some things you can do to reduce pollution in the air, water and landfills.

Philippines’ BDO Unibank first blue bond gets US$100 million investment from IFC

Philippines’ BDO Unibank first blue bond gets US$100 million investment from IFC

The International Finance Corporation (IFC), the private investment arm of the World Bank Group, is pouring US$100 million into BDO Unibank Inc’s blue bond, which aims to finance projects that will help tackle marine pollution in the Philippines.

The country is considered the third largest global contributor of ocean plastic, with an estimated 0.75 million metric tonnes of mismanaged waste entering the ocean every year, according to a World Bank study published in 2021.

The coastal blue economy is critical to the Philippines but is threatened by pollution, unsustainable fishing, rapid urbanisation, and the impact of climate change such as typhoons that drag tonnes of rubbish into seaside areas.

BDO Unibank Inc’s blue bond, the first of its kind in the country and a first for IFC in the East Asia Pacific region, is slated to raise money for projects such as water conservation, wastewater treatment, plastic recycling, sustainable tourism, fisheries, and sustainable seafood processing, the global development institution said in a statement on Friday.

“A blue bond instrument will be key to the nation’s growth trajectory. By supporting the first blue bond issuance in the country, IFC continues its tradition of supporting the development of capital markets through issuances of thematic bonds and mainstreaming climate finance in the banking sector”, said Jean-Marc Arbogast, IFC country manager for the Philippines.

“Moving forward, a robust blue economy will help create jobs and alleviate poverty while strengthening the marine ecosystem in the Philippines.”

IFC will also help BDO identify projects that can combat water stress with rapid urbanisation, as more than 3 million people in the Philippines rely on unsafe and unsustainable water sources and 7 million lack access to improved sanitation.

 

…A blue bond instrument will be key to the nation’s growth trajectory…a robust blue economy will help create jobs and alleviate poverty…

Jean-Marc Arbogast, country manager for the Philippines, International Finance Corporation

 

The bond will be issued under the International Capital Market Association (ICM’s) Green Bond Principle and IFC’s recently launched Blue Finance Guidelines, a blue-specific framework and metrics that monitor the use of proceeds and report on relevant impact.

“Marking our two-decade partnership, IFC’s investment will be key to helping BDO develop a Blue Finance Framework that will allow us to fund projects that support the country’s blue economy while establishing a new asset class in the Philippine debt market,” said Teresita Sy-Coson, chairperson of BDO Unibank, Inc.

Blue financing is emerging in Asia, with the IFC piloting the mechanism in China, India, Indonesia, and Thailand. Last year, multi-lateral lender Asian Development Bank issued its first ever dual-tranche blue bonds denominated in Australian and New Zealand dollars that will finance ocean-related projects in Asia and the Pacific.

The “blue economy”, which includes livelihoods and other economic benefits derived from oceans, is expected to reach US$3 trillion and employ 40 million people by 2030, giving it critical role in pivoting the global economic system towards regenerating ocean health, said the World Bank.

Wetlands not Wastelands: Coca-Cola and Earthwatch announce a $600k partnership to tackle marine pollution in remote Australia

Wetlands not Wastelands: Coca-Cola and Earthwatch announce a $600k partnership to tackle marine pollution in remote Australia

The Coca-Cola Australia Foundation (CCAF) and Earthwatch Australia have announced a $600,000 partnership to deliver a first-of-its-kind marine pollution and wetland management program in the Lower Gulf of Carpentaria.

Together with Carpentaria Land Council Aboriginal Corporation (CLCAC) and recycling experts Plastic Collective, Earthwatch will train 20 CLCAC Indigenous Land and Environment Rangers and 30 community volunteers to help deliver the ‘Wetlands not Wastelands’ program over the next three years.

Malcolm Hudson, Chair of the CCAF, said the program was a stand-out in the Foundation’s competitive grant process to address the United Nations Sustainable Development Goal 14 ‘Life Below Water’.

“Driven by science and delivered by the local community, this program will trial a sustainable, community-based solution to managing and recycling marine pollution in remote regions. Once this model is proven, it could potentially be replicated in many other regional and remote locations in Australia and around the world.”

Pollution is a key threat to the vast wetland system of the Lower Gulf of Carpentaria, which has little to no recycling infrastructure and has been hotspot for seasonal tourism. The area is also home to thousands of unique species including dugongs, sea turtles, migratory shorebirds and important mangrove and salt marsh wetlands that play a significant role in sequestering carbon.

Cassandra Nichols, CEO of Earthwatch Australia, said the community-led program will help reduce marine pollution risks, as well as recover and upcycle plastic waste into valuable products, creating an economic opportunity for the community.

“Thanks to this generous grant from the Coca-Cola Australia Foundation, ‘Wetlands not Wastelands’ will come to life and allow us to work directly with the CLCAC Rangers to develop a marine pollution management plan and a report card for future action to conserve this region’s precious habitat.

“We will also be able to introduce two Plastic Collective Shruders, or plastic recycling machines, into the communities of Burketown and Normanton. The Rangers will be trained in how to use the Shruders as well as how to turn plastic waste into valuable commercial products, creating a social enterprise that further supports the local community.”

The program will span hundreds of kilometres of the expansive Gulf region, from the Northern Territory border in the west, to the Staaten River on Cape York in the east. The program will also enlist the support of 30 local volunteers who will be virtually trained in citizen science methods to increase the scale of the program.

Murrandoo Yanner, CLCAC Director and Traditional Owner, said the project presents an exciting opportunity for the local community.
