A Boeing-backed start-up is planning to put a hybrid-electric aircraft into commercial service within five years. Zunum Aero's 12-seat plane will carry battery packs and a small fuel reserve for a back-up engine. They aim to get you to places faster, at less cost, with planes that are quieter and have far lower emissions, as well as connect thousands of communities that don't currently have regular air service. Their first model will fly about 1130 kilometres, far enough to ferry travellers from Boston to Washington or Silicon Valley to Los Angeles.

A 2023 start-up aiming to make recycling convenient and accessible to all is about to go national. The aim is to provide people with a home pick-up option for some of the "trickier" items the normal recycling bins can't handle - including soft plastics. https://wastemanagementreview.com.au/recyclesmart-goes-national/
A Kyushu University study (2021) estimated there were 24.4 trillion pieces of microplastics in the world's upper oceans or roughly 30 billion 500-ml plastic water bottles. Microplastics are tiny, toxic and very hard to remove from the environment. But researchers in the US have discovered that some Natural Deep Eutectic Solvents (NADES) can attract and bind microplastics, making it easier to remove them from the environment. And the N in NADES is key - natural - in this instance, think extracts from plants. https://www.research.uky.edu/news/researchers-develop-eco-friendly-magnet-battle-microplastics
