Founder William Brightman explains the concept behind his coffee scrub idea: "Having received a cafetiere for Christmas, I began making my own coffee. However, I realised that post-brewing, the freshly brewed grounds had to be thrown away. With more than 55 million cups of coffee drunk every day in the UK, this represents a big waste problem. Indeed, it turns out that more than 500,000 tonnes of coffee grounds are sent to landfill every year in the UK alone! I saw an opportunity to change this." You might have thought that these coffee grounds would be harmless. However, they are actually highly polluting and need lots of precious oxygen to break down. They decompose to methane, a greenhouse gas with more than 20 times the global warming capacity of carbon dioxide! That morning latte isn't so harmless after all.
