The plastic that biodegrades in your home compost

01:04 A gel to safely transport proteins

A gel that encases proteins could be a new way to safely transport medicines without requiring them to be kept cold, according to new research. To test it, the team behind the work posted themselves a protein suspended in this gel, showing that it was perfectly preserved and retained its activity, despite being dropped in transit and exposed to varying temperatures. The researchers hope this gel will help overcome the need to freeze protein-based medicines, which can be expensive to do and difficult to maintain during transportation.

11:24 Making a plastic biodegradable

By embedding a plastic with an engineered enzyme, researchers have developed a fully biodegradable material that can be broken down in a home compost heap. Plastic production often requires high temperatures, so the team adapted an enzyme to make it more able to withstand heat, while still able to break down a common plastic called PLA. They hope this enzyme-embedded plastic could replace current single-use items, helping to reduce the huge amount of waste produced each year.
