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 ever increasing cost of fossil fuels and its attendant pollution menace has provided the pedigree to consider alternative sources of energy. An investigation was launched into the design and construction of an Anaerobic Digester system from locally available raw materials using local technology and the production of biogas from food wastes and Human excreta generated within a University cam...

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...

Biogas technology has been used quite extensively to generate renewable energy from organic wastes while also recycling nutrients in the wastes and reducing harmful emissions. However, the challenges of low biogas yield from recalcitrant and inhibitory solid wastes together with high construction and operation costs of bioreactors have impeded optimal performance through this process. Additiona...

BACKGROUND Materials rich in lignocellulose, such as straw, are abundant, cheap and highly interesting for biogas production. However, the complex structure of lignocellulose is difficult for microbial cellulolytic enzymes to access, limiting degradation. The rate of degradation depends on the activity of members of the microbial community, but the knowledge of this community in the biogas proc...

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...

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...
