The proteomics analysis could contribute to better understand about metabolic pathways in anaerobic digestion community because it still as a “black-box” process. This study aimed analyze the proteins of co-digestion performed reactors containing residues from first and second generation ethanol production. Metaproteomics was carried out for three types samples: sludge without substrate (SI), s...

As a typical mode of energy from waste, biogas technology is of great interest to researchers. To detect the trace H2S released from biogas, we herein demonstrate a high-performance sensor based on highly H2S-sensitive SnO2 nanocrystals, which have been selectively prepared by solvothermal methods using benzimidazole as a mineralization agent. The sensitivity of as-obtained SnO2 sensor towards ...

The proper management of solid waste is the need of the time. The solid waste consists of various components, some of them are biodegradable where as other are non biodegradable. The waste from various biodegradable sources could be utilized as a feed material for the gas production. The objective of this study is food waste management through biogas production. Various parameters were studied ...

The major purpose of this study was to examine the advantages and implications of biogastechnology in the agriculture sector. Biogas is one of many biomass energy sources, which includeanything that was once alive and that can generate energy (except for fossil fuels, which are notrenewable). To talk of biogas is to talk of agriculture, since biogas generation starts withagricultural waste prod...

This paper proposed a framework to model and optimises a biogas production using artificial neural networks and genetic algorithms. The intelligence computation was applied to achieve a better model and optimisation compared to a mathematical modeling. Two training approaches were used to train a set of neural networks design. The trained networks model predictions were used to generate a maxim...

The paper presents a new mathematical model of anaerobic digestion based on mass balances of organic dry matter (oDM) and nitrogen. The model was used for simulation of two agriculture biogas plants. The results of simulation in respect of biogas and methane yield, concentrations of ammonium nitrogen and dry matter (DM) in digested sludge, showed a satisfying compliance with measurements. Based...

The production of biogas has many advantages against other biomass based processes for production of energy or fuel. Biogas can be produced from any type of biomass whether it is a pure substrate or if it is a mix of materials like source-sorted municipal organic solid waste. The biogas process can handle substrate with different water content, from wet materials like Sewage sludge to dry mater...

In this study, biogas residue fermented by engineering was used as compost raw material, and different quality biochar added in the composting process to explore effect of on transformation heavy metals process. The comprehensively analyzed with potential ecological risk assessment redundancy analysis. addition 10.0% during had a strong passivation exchangeable Cu Cd, rates 11.75 63.89%, respec...

We find that the minimum distance of the binary [137; 69] quadratic residue code is 21.

Anaerobic digestion is a process in which microorganisms degrade organic material, such as dairy manure, in the absence of oxygen to produce biogas and digestate. Biogas is composed mostly of methane, which is the main constituent of natural gas (Table 1). Digestate is the degraded organic material that exits the digester after the digestion process. Digestate contains nutrients that can be use...
