Biogas Production from Tannery Liquid Waste

Biogas production from tannery wastes – Evaluation of isolated microorganisms effect

The disposal and treatment of wastes generated in the leather industry has been the focus of several studies around the world. They intend to meet environmental legislation and make the process environmentally and economically viable. The anaerobic digestion process, which occurs in steps that involve acid and methane forming bacteria, can be an alternative since it turns the waste into renewab...

Production of Biogas from Poultry Waste

It is inevitable that with large volume and high density poultry productions, there will be large quantities of poultry waste produced in Kathmandu and throughout Nepal. Poultry waste produced as the daily feeding of chicken both from broilers and layers in the country is largely used as organic manure for agricultural purposes. The poultry industry is growing day by day concentrated within the...

Anaerobic Treatment and Biogas Production from Organic Waste

Organic wastes under consideration are of natural origin that possess biochemical characteristics ensuring rapid microbial decomposition at relatively normal operating conditions. When considering the organic waste treatment we have generally in mind organic mineralization, biological stabilisation and detoxification of pollutants. Most common organic wastes contain compounds that are mainly we...

Biogas Production and Nutrient Recovery from Waste Streams

Waste streams such as municipal wastewater and animal manure contain organic materials and nutrients that can be converted and recovered for bioenergy and renewable fertilizer production. In the first part of this thesis, the anaerobic co-digestion of dairy manure with kitchen waste and chicken fat was studied for the purpose of increasing biogas production. The methane yields of co-digestion s...
