Procedeul are la baza utilizarea unei prese de compactat care poate realiza o forța de presare corespunzătoare unui grad de compactare specific fiecărui tip de deseu, in acest scop sistemul electronic de comanda fiind reglat pentru cinci presiuni si trei de debite cuprinse in domeniul de lucru. Echipamentul începe sa lucrează la o presiune prestabilita si specifica fiecărui tip de material in parte, iar daca aceasta se dovedește, in cazul concret de presare a fi insuficienta pentru deseul utilizat, echipamentul are posibilitatea de a trece automat, folosind o supapa hidraulica proporționala, la următoarea treapta de presiune, in mod succesiv pana la atingerea gradului de compactare necesar. In acest caz, debitul poate trece la o treapta inferioara, pentru încadrarea in puterea si caracteristica de reglabilitate a presei pi x Qj < NmaxThe process is based on the use of a compaction press that can achieve a pressing force corresponding to a degree of compaction specific to each type of waste, for this purpose the electronic control system being adjusted for five pressures and three flow rates within the working range. The equipment starts working at a predetermined pressure and specific to each type of material, and if this proves, in the specific case of pressing to be insufficient for the waste used, the equipment has the possibility to move automatically, using a proportional hydraulic valve, to the next pressure stage, successively until the required degree of compaction is reached. In this case, the flow can move to a lower stage, to fit the power and adjustability characteristic of the press pi x Qj <N ma x
