to create compost using biodegradable materials; to add compost to the ground
Composter has two everyday meanings in France: to validate a train ticket by stamping it (composter son billet avant de monter), a near-universal instruction at French train stations, and to compost organic waste (composter ses déchets de cuisine).
Composter (with a t) means to validate a ticket or compost waste — it's a false friend for "to compose," which is composer without the t; mixing the two up is an easy typo or pronunciation slip for English speakers.
