Waste Nutrient Solution as an Alternative Fertilizer in Curled Mallow Cultivation

Biomass Gasification: An Alternative Solution to Animal Waste Management

Thermogravimetric analysis was used to examine the thermal behavior of dairy manure as a pyrolysis and combustion feedstock. Nitrogen and air were used as purging gases to analyze the pyrolysis and combustion reactions, respectively, and heating rates of 20 o C min -1 , 40 o C min -1 and 60 o C min -1 were applied. An Arrhenius model was used to estimate the kinetic parameters (activation energ...

Associations between Schistosomiasis and the Use of Human Waste as an Agricultural Fertilizer in China

BACKGROUND Human waste is used as an agricultural fertilizer in China and elsewhere. Because the eggs of many helminth species can survive in environmental media, reuse of untreated or partially treated human waste, commonly called night soil, may promote transmission of human helminthiases. METHODOLOGY/PRINCIPAL FINDINGS We conducted an open cohort study in 36 villages to evaluate the associ...

Material resources, energy, and nutrient recovery from waste: are waste refineries the solution for the future?

Waste refineries focusing on multiple outputs of material resources, energy carriers, and nutrients may potentially provide more sustainable utilization of waste resources than traditional waste technologies. This consequential life cycle assessment (LCA) evaluated the environmental performance of a Danish waste refinery solution against state-of-the-art waste technology alternatives (incinerat...

Waste Treatment by Algal Cultivation

Microalgae Cultivation in Wastewater for Nutrient Removal

Wastewater is the spent or used water containing dissolved or suspended solids such as pollutants and microbes, including nutrients. The wastewater discharged into the water bodies are hazardous to environment and cause various health problems in human beings. Eutrophication is one such major environmental problem caused due to the discharge of nutrient rich wastewater into the nearby water bod...
