A waste digestion system including a primary digester and one or more first subsequent digesters for processing non-liquid organic waste material without the addition of external heat using thermophilic aerobic bacteria to produce a stable product, said digesters being configured to contain contents ...
Enzyme catalysis initially involves the substrate binding to the active site of the enzyme to form an enzyme–substrate complex as an intermediate state. As the reaction progresses, the enzyme detaches from the products without being consumed itself [3]. The active sites of an enzyme consist of ...
Anaerobic co-digestion of yard waste, food waste, and pig slurry in a batch experiment: An investigation on methane potential, performance, and microbial c... ACoD of OFMSW is effective for biomethane production.This study examined ACoD of YW, FW, and pig slurry at various YW percentages....

Global operational waste destination mixApproximate percentage of waste by destination type (by weight) Recycling/reuse: 70% Donation to people: 5% Animal feed: 4% Composting: 1% Anaerobic digestion: 1% Incineration (with and without energy recovery): 1% ...
Anaerobic digestionspeeds up the composting process by removing oxygen from the environment and capturing the biogas that is produced. The biogas can be converted into electricity, heat, and more. The process also produces a byproduct, calleddigestate, which can be used as fertilizer or for animal...
This invention is developed by including the intermittent sequential ozonation process to the commonly employed aerobic biological sludge digestion process, which is used for reducing the amounts of b
A systematic study on thermophilic anaerobic digestion of poultry waste was carried out at North Carolina State University over the last 35 years. The concept and experiments were initiated in the laboratory and technical feasibility was proven by a pilot-scale digester on the university farm and ...
Soil pH was measured in a 1:2.5 soil/water slurry. Determination of total N, P, and K (TN, TP, and TK) in soil samples were according to Kjeldahl digestion, molybdenum antimony colorimetry and the flame photometry, respectively73. Available N, P, and K (AN, AP and AK) in soil samp...
However, capital and operating costs for valorization facilities were not covered since they depend on contextual factors around location, size and scale among others which are beyond the scope of this study. 3.2.1 Anaerobic digestion In an AD process, the quantity of biogas that can be ...
