What is two-stage (phased) digestion?
derived
Two-stage digestion separates hydrolysis and acidogenesis in a first reactor from methanogenesis in a second, letting each microbial group work at its own optimum pH and retention time. It can raise yield and stability for some feedstocks, at the cost of extra capital and control complexity.
