Mushrooms can be made into bricks that are strong enough for building structures. They are solid, lightweight, biodegradable, made with agricultural waste, and producing them creates no carbon emissions. Source
AMAZING! Totally edible, easily biodegradable, sustainable disposable cutlery. KICKSTARTER CAMPAIGN until mid April 2016. I'm so blown away by this, such a good idea. One of those things that seems so obvious, hard to believe no one has done it before. "We are gearing up to create the world's first mass produced edible cutlery. This has huge potential to prevent plastic waste."
