Since 2013, sorting food waste is mandatory depending on the quantities you produce or hold.

You must estimate the quantities you produce or hold to comply with the legislation. The French law of July 12th, 2010 on National Commitment for the Environment, known as the “Grenelle 2” Act, with articles l. 541-21-1, l. 543-225, et seq. of the French Environment Code  that came into effect as a staggered obligation through decree on July 12th, 2011  includes application methods set by the circular of January 10th, 2012.

Since January 1st, 2016 a decree has required all sites producing more than 10 tonnes of biodegradable food waste per year (preparation waste, returned trays, unsold goods, etc.) to recycle this waste.


If you do not recycle this waste yourself, the law now requires you to carry out selective sorting on site and to find specific and appropriate recovery channels, internally or externally.



Composting is an aerobic transformation process of fermentable materials under controlled conditions. It produces a stabilised fertilising material rich in humic compounds, called compost, which  if of sufficient quality  can be used as an organic soil conditioner to improve soil structure and fertility.


CO2 and NFU 44-051 organic soil conditioner

Carbon dioxide (C02) is a colourless, inert, and non-toxic gas. It is produced naturally by volcanic eruptions, plant, animal and human respiration, natural forest fires, decomposition of dead organic matter from plants and animals, etc.

Organic soil conditioner (NFU 44-051): organic fertilisers are made from living matter (animal, plant, fungal, bacterial, etc.). They are derived from animal matter, animal excrement (manure), human excrement, and plant matter (compost). Natural organic fertilisers include animal waste, peat, manure, slurry, and are highly sought after for organic farming.


Digestate: organic soil conditioner

During the digestion by thermophilic aerobic bacteria within our TERRA Box composter, the biodegradable organic matter (lipids, proteins, carbohydrates, cellulose, hemicellulose) is altered, part of the nitrogen is mineralised, as well as the organic phosphorus, which becomes easily assimilable with potassium, which gives a nutrient ratio (NPK).

The stabilised digestate is generally used as a fertiliser or soil conditioner. A quality digestate increases agricultural yield by providing nutrients and helping maintain or restore soil humification. It is comparable to compost in terms of microbiological analyses, but material decomposition is achieved in 24 hours rather than 1 YEAR for conventional compost! This process is all the more important and efficient for stakeholders in the catering industry.
