Wind turbine blades are typically made of several layers of glass or carbon fibre infused with a liquid plastic resin or epoxy. This creates a composite material that is strong and durable - as well as challenging to recycle. Researchers at Aarhus University in Denmark have successfully conducted a proof-of-concept chemical recycling experiment during which they were able to "break down the epoxy material to recover both the plastic’s building blocks and the glass fibres inside without damaging either." https://www.technologyreview.com/2023/05/02/1072520/how-chemists-could-give-new-life-to-old-wind-turbine-blades/

Notpla ( not plastic) provide a range of all-natural packaging solutions made from seaweed. They are 100% biodegradable and home-compostable - just like a piece of fruit. The team behind Notpla first bought the world Ooho's - edible sachets filled with water - used in the London Marathon. But have expanded to deliver sauce sachets, pipettes, paper, film-based packaging, rigid protective packaging and water/grease proof coatings for takeaway food containers. https://www.notpla.com/

On construction sites, big power loads are needed for big equipment. Often much of this power comes from diesel generators. Diesel is a highly polluting fossil fuel, spills can occur, and diesel generators can be very noisy. AMPD Energy has designed a continuously operating battery storage system that is safe for the rough and tumble of construction sites, 30% less noisy and of course produces no diesel particulates and 85% less CO2. Most importantly they are able to deliver the high-power loads needed, for example, to run massive equipment like cranes.https://www.ampd.energy/

Algae has been studied for years as a potential source of biofuels. But its potential as a natural source of wax to replace the carbon intensive petrochemicals used in many of our non-organic cosmetics, body-care and sunscreen products is pretty new.https://www.whoi.edu/press-room/news-release/natural-wax-holds-promise-to-replace-petroleum-in-cosmetics-and-personal-care-products/

Nuclear Fusion remains an elusive source of clean, abundant, non-radioactive energy. This is largely because the temperatures needed to fuse elements together have traditionally required so much energy the whole reaction results in a net loss of energy.  By introducing lasers to speed up the heating process, some net energy gains have been demonstrated - albeit for very short durations. But a radically different approach, which uses lasers to accelerate the movement of hydrogen through boron, holds the potential promise of being able to generate petawatts of clean, non-radioactive electricity directly from the unit.    https://youtu.be/OlGzt9ur1bY

Using an integrated system of ground-to-space water quality monitoring systems for inland, estuarine and near-coastal water bodies, CSIRO thinks they might soon have a "weather forecast" capability for our waterways. More than just a health guide for recreational swimming, advanced warning of environmental events like dropping oxygen levels or potential algae blooms or expansive sediment flows, can help us to better understand, manage and ultimately protect our precious water resources. https://www.csiro.au/en/about/challenges-missions/AquaWatch
