ID'O CONCEPT (OCENE) - VAL'ID (2001)
Plateform for manure recycling
VAL'ID is a platform of stamping accelerated without admixture, odourless, without streaming.
Using the technique of the stamping in forced aeration, VAL'ID is a silo, in kit, consisted modular elements in reinforced concrete juxtaposed. Air injected regularly by a blower forces aeration of the compost and kills the admixture.
Furthermore the air injected kills anaerobies bacteria, source of gas and smell and accelerates the degradation of the compost thanks to the aerobic bacteria. Probes (oxygen, temperature, pH) pilots the blower. A set of electrovannes regulates the pressure and the air debit, which avoids the creation of privileged air ways.
A cover isolating the system of the outside environment (middle) so avoids the streaming. The strict conditions of contract (Report carbon / nitrogen = 30, pH between 6 and 8, humidity = 45 %) should be respected by the breeder during the completion made with a simple expander in fertilizer. Technically, the stake of the system is a simple joining of the modular elements, which can be easily installed and moved. The use is simple: the breeder fills the silo, covers the whole and obtains within 6 to 8 weeks a quality compost, regular and normalized (NFU 44051). The system allows breeders to treat fertilizers as a product and not as a rubbish.
Point of view of the jury: a solution to a major issue at this time
Award-winner testimony: VAL’ID brand of OCENE is glad that this technique of the stamping in forced aeration has been selected in the Top 100.
Originally dedicated to small poultry farms, it is now adapted to poultry, bovine and ovine farms. But also to solids resulting from the separation of manure and digestates, to institutional wastex (sludge from waste water treatment plants and green waste), and to waste arising from agro-food industries.
More than 350 platforms have been installed, in a dozen of countries.
The aim is still the same : sanitize and standardize waste.
