To fully model the anaerobic digestion process, biological and physico-chemical background, the kinetics of bacterial growth, substrate degradation and product formation have to be taken into account. The presented approaches differ depending on the requirements and the developer of the model....

Biogas upgrading using bottom ash from the incineration of municipal solid waste (MSW) is especially interesting for integrated treatment facilities as it would allow closing a complete loop in MSW management. The aim of this research was to assess the interaction between bottom ash (BA) and...

Anaerobic digestion applied to the organic waste produced in urban environments could provide a critical solution to growing garbage problems while simultaneously reducing external energy requirements. As landfills across Canada and the rest of the world are filled to their limits, a...

Biodegradation of palm oil mill effluent (POME) under anaerobic conditions to environmentally acceptable products was carried out. This method of digestion was chosen in preference to the aerobic mode, among other factors, efficiency of COD and BOD removal and relevance of the operation to the...

The production of biogas through the anaerobic digestion of cattle manure and its subsequent use in the generation of electricity on larger farms in Ontario is currently economically attractive. This is a result of the Ontario Feed-In Tariff (FIT) program, which provides incentivized rates for...

The effect of chemical pretreatment and particle size on anaerobic digestion of bagasse and coconut fibres by rumen micro organisms was studied. Both chemical pretreatment and pa rticle size affected total fibre degradation and productions of methane and volatile fatty acids from these waste...

Biogas may be readily obtained by the anaerobic digestion of organic waste. If communities and towns could harness the energy which is contained in the organic waste which they presently dispose of in landfills or compost, this fuel could supplement or completely satisfy their heat energy...

The objective of this study was to characterise anaerobic batch biodegradation of potato waste alone and when co-digested with sugar beet leaves. The effects of increasing concentration of potato waste expressed as percentage of total solids (TS) and the initial inoculum-to-substrate ratio (ISR)...

Biogas is a promising renewable fuel, which can be produced from a variety of organic raw materials and used for various energetic purposes, such as heat, combined heat and power or as a vehicle fuel. Biogas systems implementation are, therefore, subjected to several support measures but also to...
