) and the initial inoculum-to-substrate ratio (ISR) on methane yield and productivity were investigated. The ISRs studied … were in the range 9.0–0.25 and increasing proportions of potato waste from 10% to 80% of TS. A maximum methane yield of 0 ….32 l CH4/g VSdegraded was obtained at 40% of TS and an ISR of 1.5. A methane content of up to 84% was obtained at this …

-determined calorific values, and to the energy recovered through a batch biochemical methane potential test. A semi-continuous digestion … the substrate gave a methane yield of 0.345 L g-1 VS added with VS destruction 81.3%, and showed that 76.2% of the … measured calorific value of the waste could be reclaimed as methane. This was in good agreement with the estimated energy …

Greenhouse gases especially methane has been proven to have a significant effect on global warming and climate changes …. Large share of methane is emitted to the environment from wastewater treatment plants mostly from uncovered anaerobic … digesters. The estimated methane emission is approximately 618Mt carbon dioxide-equivalents (CO2-e) globally. Methane emissions …

Converting glycerol, a by-product from biodiesel production into useful products and energy could contribute to a … positive life cycle for the biodiesel process. One kg of glycerol is produced for every 10 kg of biodiesel and has the … Gasification (CSCWG) processing of crude glycerol solutions is one such viable option. Above its critical point [>221 barg, >374 °C …
