Evaluation of Stability Parameters for Landfills
… and tested as an enhanced environment for biochemical degradation of municipal solid waste. All the landfills are regulated under Subtitle D of the Resource Conservation and Recovery Act (RCRA). The shortage of time and money has limited the amount of research done on waste stability …

Biochemical Lignin Related Processes in Landfills
… The cellulose to lignin ratio (C/L ratio) and biochemical methane potential (BMP) were the main biological stability parameters used.

Cattle manure characteristics in relation to manure accumulation period and seasonal impacts in the intermountain west
… used to produce biogas, which mainly consists of methane gas that has multiple purposes. Arguably the most important purpose methane gas has is that it is a renewable energy source. Organic waste that can serve as feedstock for AD ranges from food waste to animal waste, including manure. There are …

Enhancing biomethane production from anaerobic digestion of Sargassum muticum
Higher methane yields from the anaerobic digestion (AD) of Sargassum muticum could improve the process energy balance and make its use during AD more economical and energetically favourable. Previous research showed that after 28 days of AD, methane yields from S. muticum were low (17% of the …

Biodegradation of leather solid waste
… in the research include: anaerobic digestion, Biochemical Methane Potential (BMP), Total Solids contents (TS), Gas Chromatography (GC) and Gas Chromatography Mass Spectrometry (GC-MS). Hydrolysable tannins are less resistant to anaerobic digestion than condensed tannins. However, enzymatic …

A Non-isolated Half Bridge Buck-based Converter For Vrm Application And Small Signal Modeling Of A Non-conventional Two Phase Bu
… more biodegradable byproducts (measured as 5-day biochemical oxygen demand/chemical oxygen demand). Finally, both treatments were found to oxidize larger molecules (>1000 dalton) and produce smaller molecules, as indicated by an increase in smaller molecule contribution to organic carbon. In part …

Experimental investigation of biogas production from feedlot cattle manure
… after 41 days. The biogas was analysed for methane and carbon dioxide content using a gas chromatograph. A techno-economic model was developed in terms of the design of a simple agricultural biogas plant and the economics of the plant. The same manure sample was divided into different …

Evaluation of solid food waste for biogas and manure production: a case study of the University of Venda Canteen Solid Food Waste
… Lack of awareness and adequate knowledge of the potential of FW for biogas and manure production could be the reason for the observed slow uptake of AD in South Africa. This study evaluated the energy and manure production potential of solid FW generated by a typical South African university (the …

CHALLENGES IN TRACKING THE DEGRADATION OF LANDFILLED MSW THROUGH LABORATORY AND NUMERICAL MEANS
… Thus, a measurement of the remaining biological potential of in situ waste can assist with the understanding and prediction of these ongoing landfill process, while also providing a means of assessing the degree of (biological) landfill stabilization. The research presented here will focus on the …
