Community composting in Rennes Métropole

The first community composing bin in Rennes Métropole was installed in 2006, in the garden of a block of 48 flats. Afterwards, the demand grew, and now 190 community composting bins serve more than 2000 households. After a feasibility study and if practical conditions are met, the contractor of Rennes Métropole, Eisenia, accompanies the households throughout the whole composting cycle, including communication with the inhabitants, monitoring of compost making and training provided by a master composter. The participating inhabitants commit to take their fermentable kitchen waste (such as fruit and vegetable peelings or coffee grounds) to the composting bin. In return, Rennes Métropole provides them with a bio-bucket, which allows them to stock the waste before it is taken to the composting bin. The building managers are also involved in the process, by facilitating information to inhabitants, feeding the composting bin dry matter and putting tools at the inhabitants’ disposal. In the same way, community composting is implemented in households from the same neighbourhood or district. In order to promote the composting technique, Rennes Métropole organizes free training sessions to inform people about how to make compost and how to manage garden waste, and to train volunteers to become master composters.
