Purpose This study aims to ascertain the physiochemical characteristics of the compost made from recycled cotton spinning waste (CSW) for Indian Spinach cultivation in Bangladesh. Method The physiochemical characteristics of the compost made of fresh cotton spinning waste (CSW), cotton spinning waste ash (CSWA), rice husk (RH), rice husk ash (RHA) with varying ratios following open […]
Purpose: Poultry manure (PM) is a concern for Bangladesh. The improvement of quality and safety is always desirable. The experiment assesses the quality and safety parameters of PM with the addition of Saccharomyces cerevisiae and indigenous microorganisms (IMO) in different fermentation conditions (aerobic, facultative anaerobic, and anaerobic) for 7 days. Method: Fermentation condition × treatment […]
Purpose Due to the urgent need for sustainable agro-industrial waste management, a field experiment was conducted to evaluate the application of biosolids as organic fertilizer in a corn cultivation crop. In addition, to achieve food security, the study aimed to assess metals concentrations in soil and maize plants and enrichment factors (EF) for soils and […]
Purpose The study assessed the quality of compost produced by the Black Soldier Fly Larvae (BSFL) in terms of the compost nutrient level, microbial activities, and the bioaccumulation of possible heavy metals in the organic solid waste. Method The study used the pre-experimental study design, one-group pretest-posttest to obtain the data. Five experimental units were […]
Purpose: There is an increasing trend of using sewage sludge co-composting to produce bio-fertilizers for use in agriculture. However, existing studies on the quality of the produced compost came out with contradicting results, which hinder its sustainable utilization. Hence, this study aimed at assessing the quality of sludge based compost for agricultural use. Method: Four […]
Purpose Municipal sewage sludge generated from three operational wastewater treatment plants, located in the Bekaa valley of Lebanon, was assessed for its potential use as agricultural soil amendment. Method Sludge samples were taken from three treatment plants located in the villages of Iaat, Ablah and Joub Jannine during the summer season of 2018, from June […]
