Trattamento HYST delle biomasse: risultati per l’alimentazione animale e le bioenergie

Hypercritical Separation Technology (HYST) is an innovative technology for the processing of biomass which is achieving significant results in the field of nutrition (both animal and human) and renewable energy. . In the livestock sector, the HYST processing of corn straw and cereal bran showed an increase in the nu- tritional value and digestibility of the processed raw material. This capability, together with the extremely reduced working costs, appears very interesting in view of an optimization of the resources. In fact, it allows to significantly reduce the production costs, besides solv- ing the difficult problem of waste materials that are difficult to dispose of. The lignocellulosic biomass (corn straw), once pre-treat- ed with the HYST system, showed excellent perform- ances in the processes of anaerobic digestion for the production of biogas, due to both the good miscibility in the sludge of the digester and the excellent biogas yield. The latter, assessed per ton of material as it is, set on val- ues equalling 2.5 to 2.8 in regard to those of corn silage.
