It may sound like Day of the Triffids in reverse, but it might just be that mushrooms are about to save the planet.
Bloomberg Business Week reports on the work of Eben Bayer and Gavin McIntyre and the innovative work on plastic substitutes that they have been doing with mushroom fibres:
It starts with a mash of corn stalks and vegetable husks impregnated with mushroom spores. The fungus eats the plant nutrients, then grows a complex root network that fills the shapes of the molds. The final product is a foam that looks something like a big wafer of nougat candy. It is placed in an oven to stop the spores from growing and to give the material the proper texture, hardness, and elasticity.
“The products literally grow themselves. In the dark. With little to no human contact,” says McIntyre. Each mold can be treated to create a material with different qualities. Home insulation must be fire-retardant and energy efficient; cabinets have to be sturdy; a car dashboard or bumper has to be strong but with give.”
And to get rid of it?
Simply throw it on the compost heap and it is gone in weeks.
The reason this is so important?
Polystyrene is non-biodegradable and so takes hundreds of years to disappear. The blowing agents that are used to expand it can be highly flammable. Some versions of it are made with hydrofluorocarbons that are over a thousand times more potent in terms of global warming potential than carbon dioxide. It is also regularly excluded from recycling services as it is uneconomical to collect and compact (due to its lack of density versus the space it occupies).
The company behind the mushroom fibre revolution, Ecovative Design, has just signed a deal with the packaging behemoth Sealed Air, the company responsible for Bubble Wrap and Cryovac. Both Dell and Steelcase are already using the material for packaging and it promises a biodegradable revolution in how we ship stuff.
I wonder if this is something that the impressive Centre for Process Innovation should pick up here in the UK? They are the increasingly impressive outfit based in Redcar. In their own words:
“CPI helps companies to prove and scale up processes to manufacture new products and create more sustainable, efficient and economic industries of the future.”
There is some real talent out there in the British economy, particularly in the emerging green and high-tech industries. A UK angle on this would help boost manufacturing, jobs and the wider economy, whilst at the same time helping to tackle the huge waste problem there is with packaging.
