Consider this over your morning coffee: Almost half the biomass of the coffee cherry — the fruit that contains coffee beans — ends up as processing waste. With worldwide coffee production reaching 9 to 11 billion pounds on an annual basis, that’s a lot of byproduct to handle. Thankfully, industry players keep striving to solve this problem. Here are six ways they are turning coffee waste into a resource.
At FirstEnergy Stadium in Cleveland, a new partnership with the Cleveland Browns and the Innovation Center for U.S. Dairy has implemented a new system which will divert an estimated 35 tons of stadium food waste from landfills into biodigesters for conversion into energy. The system, called Grind2Energy, is far more than an industrial-strength garbage disposal — it’s an integrated system that includes leasing, installation, and service coverage of a closed system that grinds up food waste into a slurry and transports it to an anaerobic digestion facility where it is converted to energy.
