The cup might be empty when you’re done your morning coffee, but there was a lot left behind in the process of making it.
Hans Langenbahm, a former anthropologist who worked in coffee-producing countries before becoming the head roaster at Ottawa’s Happy Goat Coffee, said most of the coffee plant isn’t used.
“In the cup is only two per cent, so 98 per cent gets somehow lost,” he said on CBC Radio’s Ottawa Morning.
He said after the bean is extracted, a lot of the plant is tossed aside and the ground beans themselves also become waste.
“In Canada, alone we produce about 600 tonnes of spent coffee grounds a day,” he said.
