The commitments of the PENA GROUP :
In pursuit of the constant improvement of waste recycling, we have patented the ADONIS industrial process for the composting of organic wastes: green wastes, animal by-products, manure, animal litter, food wastes, etc…
The conformity of source wastes is systematically controlled, in order to ensure the quality of compost produced. Each batch of compost, further to validation by analyses, is then made available for sale, thus discharging our client from their responsibility as a waste producer.
The procedures and organizational structure which we have deployed allow us to guarantee the full traceability of source materials.
Our composting operations began in the late 1990s. Research work which we have conducted in this field has led to the filing of a patent for the “ADONIS” in-vessel composting process, which specifically employs slurries from treatment plants.
