In 2009 an estimated 12 million tons of coffee waste was left to rot. Not only does this waste generate methane gas which is attributed to climate change, it is also a huge amount of money being wasted. But there is hope.
A scientist from Hong Kong, Shuting Chang, has demonstrated that coffee waste is an ideal substrate for farming tropical mushrooms like shiitake and ganoderma. This would mean millions of pounds worth of waste can be reused to create another product that in turn would make money.
This discovery is economical, sustainable and a positive step for the future. These types of discoveries, finding sustainable solutions for society inspired by the principles of nature, are made all the time with the help of companies such as The Blue Economy.
