Sustainability assessment of biogas production from buffalo grass and dung: biogas purification and bio-fertilizer
Biomass from wetland aquatic grass and buffalo grass can be exploited for biogas production, because this substrate is plenteous and does not compete with food production. In this study, the grass substrate was physically pretreated by boiling with different retention time to increase its biodegradability and was examined in batch mode. Boiling pretreatment suggested that 100 °C with 2 h retent...
متن کاملUtilization of Co-digestion of Local Brewery Wastes and Cattle Dung as a Potential Source of Biogas and Organic Fertilizer
Biogas production from co-digestion of local brewery waste (BW) and cow dung (CD) was study for value added to this solid waste. The objective of this research was to fine the optimum condition for maximum biogas production and also examined the effectiveness of the biogas residue (liquor from anaerobic digestion process) as a nitrogen source for the production of okro. The experiments were per...
متن کاملNutrient Availability to Corn From Dairy Manures and Fertilizer in a Calcareous Soil
The expansion of the dairy industry in southern Idaho has led to increased application of manures to meet crop nutrient demands that can alter the uptake pattern of both macronutrients and micronutrients. A greenhouse study was conducted to determine the effects of dairy manure, composted dairy manure, and fertilizer (monoammonium phosphate) application on soil test phosphorus (P), microbial ac...
متن کاملHygienic and sanitation requirements in biogas plants treating animal manures or mixtures of manures and other organic wastes
Introduction Until relatively recently, anaerobic digestion (AD) plants at farm or industry level treated the organic waste arisings from a single farm or from an individual industrial operation. The installation of centralised AD plants, treating animal manures and slurries from a large number of farms, and the increasing use of co-digestion of manures, food-processing wastes, sewage sludge an...
متن کاملTransport of Fecal Bacteria from Poultry Litter and Cattle Manures Applied to Pastureland
Land applications of manure from confined animal systems and direct deposit by grazing animals are both major sources of bacteria in streams. An understanding of the overland transport mechanisms from land applied waste is needed to improve design of best management practices (BMPs) and modeling of nonpoint source (NPS) pollution. Plots were established on pasturelands receiving phosphorus-base...
