Food waste

Biowaste comes from 2 large families of deposits:

• Household bio-waste which corresponds to 30% of residual household waste.
  We combine leftover meals, fruit and vegetable peelings, leftover bread, small green waste, etc.
• Biowaste from professionals (retail stores, collective catering centers, food industries, caterers, restaurants, etc.). This family of biowaste corresponds to raw or cooked kitchen leftovers, expired products from the bulk food trade, expired products from the packaged food trade or even manufacturing waste.

Pre-sort

For household bio-waste, pre-sorting is carried out at home via a bio-bucket which allows temporary storage of the bio-waste produced. The individual empties his biobucket at a voluntary drop-off point.
For professionals, storage depends on the volume produced and the space available: it can be done in bins, in pallet boxes, in a waterproof compactor, etc. It all depends on the specifics of the structure.

Collection

Household bio-waste stored in semi-buried containers is taken care of by a professional who exchanges the full container with an empty, clean container.
Bio-waste from professionals is collected with its container.
These two categories of biowaste are then transported to a transfer or deconditioning platform.

Life cycle

Recycling and recovery

The biowaste is then sent to energy and organic recovery units. Depending on the nature and quality of the bio-waste handled, one or another method of recovery is favored. Several techniques are possible depending on the two possible modes of degradation of organic matter:

• In the presence of oxygen, degradation by composting for a true return to the earth: Compost is used in agriculture or by green space services. 10m³ of fermentable waste produces approximately 1 m³ of compost.
• In the absence of oxygen, degradation by methanization (which occurs after grinding): it is a controlled anaerobic fermentation (in the absence of air) of biowaste which results in the release of biogas, which can be recovered and used as fuel. Biogas is used as fuel for automobiles or for the production of heat and energy.
