Sugar Fuel


They say that sugar is a good source of energy. Now one company is putting this into practice...literally.

A Nestlé factory in the UK uses chocolate and sweets not suitable for sale, as well as waste from sweets manufacturing processes, to produce renewable energy and clean water. The factory mixes the sweets, sugar residues, and manufacturing liquids into a “chocolate soup.” The soup is placed in an airtight tank, where bacteria breaks it down into by-products through a process called anaerobic digestion. The process produces biogas, which is used to power the factory’s energy needs.

The effort is part of the company’s goal of having 10% of its companies worldwide achieve zero waste status.

Anaerobic digestion processes have potential in other areas as well. For instance, livestock farmers in Panama and elsewhere have been given anaerobic digesters to convert animal waste into biogas for cooking, and liquid fertilizer. This help poor farmers—and because the farmers then need to use less wood for fuel, it helps preserve forests and the environment.

That’s sweet news, indeed!
