Ocean plastics

Scientists at RIKEN in Japan have developed a new type of plastic that’s just as stable in everyday use as regular plastic, but dissolves quickly in saltwater, leaving behind only safe compounds.

Torqeedo, a major innovator of all-electric boat motors, is trying to further improve its clean track record. It's deep in the works on a new version of its iconic bright-orange propeller that's crafted from 100% recycled plastic.

UK shipyard MMS has added a new member to its fleet of floating-debris collection vessels. The latest Envirocat is the first to clean up waterways without releasing engine fumes into the environment.

The flapping motion of a new robotic jellyfish is not only good for propulsion, but it can also draw small bits of debris up from the ocean floor without contact. Such a robot could remove trash from delicate ocean environments, like coral reefs.

Tentsile has built an impressive stable of suspended sleeping shelters and hammocks since launching its very first tree tent in 2012, and its latest creations land with a particularly green tinge through the use of recycled ocean plastics.

Glitter spruces up everything from makeup to craft projects, but one thing it doesn’t improve is the environment. A new biodegradable glitter swaps out the plastic and aluminum for plant-based cellulose, which can be produced at scale.

Commissioned to design a sustainable floating hotel, Margot Krasojević Architects produces a proposal that's unconstrained by practicalities. The designer envisions making use of the massive amounts of plastic in the ocean as a building material.
