5 inventions that could transform the health of our ocean

A garbage truckful – every minute. That’s how much plastic waste is being dumped in the ocean. And that’s just the plastics – chemicals and sewage are also major concerns

Ocean Action Hub reports on two ventures that are trying to turn this waste into something useful. California-based startup, Bureo – which has found a way to turn this waste into desirable products including skateboards and sunglasses – is literally closing the net on the problem.

-The ocean is estimated to contain at least 86 million tonnes of plastic waste, as well as chemical and other pollutants.
-Fishing debris turned into sunglasses and deep sea robots collecting pollution data are some of the innovations that could help clean up our seas.
-Sustainability is high on leaders’ agenda as nations and businesses consider whether ‘green growth’ will form part of COVID-19 recovery plans.

A garbage truckful – every minute. That’s how much plastic waste is being dumped in the ocean. And that’s just the plastics – chemicals and sewage are also major concerns.

But the problem is inspiring innovators to create ingenious solutions – both to capture and repurpose marine plastics, and to measure the scale of pollution in new ways.

And the need for such ideas is acute: a study undertaken by the World Economic Forum and partners has found that – without action – by 2050, the weight of plastics in the ocean could be greater than the weight of fish.

It’s a good time to look at green innovations, with many, including the Forum, advocating for businesses and governments to put sustainability at the heart of a COVID-19 recovery strategy.

1. Upcycling plastic waste

They call it ‘ghost gear:’ the estimated 640,000 tonnes of old fishing ropes, lines and nets that’s discarded or lost every year. According to Greenpeace, it’s one of the ocean’s worst forms of plastic pollution because of its powers to ensnare almost anything, from crustaceans to whales.

Another solution comes from the marine clean-up initiative, Parley. It sweeps the ocean for plastics which are turned into yarn by manufacturer Bionic.

2. Underwater robots

This September, what could be the future of shipping will cross the Atlantic: a fully autonomous craft called the Mayflower Autonomous Ship (MAS) – named in honour of the boat that carried English settlers to the New World 400 years ago.

Using AI and ‘research pods’ from the University of Plymouth, the solar-powered MAS will run experiments to monitor sea mammals and marine microplastics.

It’s not just the MAS team who are exploring new ways to collect ocean data. Terradepth, a start-up based in Texas, US, has created what sounds like a vision from science fiction: a fleet of autonomous underwater robots. The company hopes to demonstrate its technology this summer.

While Terradepth robots are likely to be hired for a range of mapping and scanning purposes, they also promise to help customers “make informed, ecologically responsible decisions regarding the world’s ocean.”
