  • Beating treatment to enhance digestibility of fresh grass

    Anaerobic digestion (AD) is one of the most popular biomass conversion technologies. AD can be further divided into four stages: pre–treatment, digestion, gas upgrading and digestate. The main goal of pre–treatment is to improve degradability of the material in order to enhance gas production and anaerobic digester performance. Beating treatment as a new mechanical treatment technique has been ...
