An excellent BMP test in the laboratory does not guarantee a stable digester in the plant. The difference between theoretical potential and real production, the so-called lab-to-plant gap, is commonly measured at between 15% and 40% when the test is run without meeting the three requirements set by the VDI 4630 standard: an adequate inoculum-to-substrate […]
