Anaerobic digestion (AD) has long been used to treat different types of organic wastes especially in the developed world. However, organic wastes are still more often considered as a waste instead of a resource in the developing world, which contributes to environmental pollution arising from their disposal. This study has been conducted at Bugolobi Sewage Treatment Plant (BSTP), where two orga...

This study aimed to investigate the effects of tow nanoparticles (NPs) on the absorption, accumulation, reproduction of the Eisenia fetida. A 4×2×2 factorial experiment in a randomized complete block design with three replications was conducted. The factors included in the experiment are the content of NPs at four levels (0, 0.4, 0.8, and 1.2gr/kg weight of substrate), the type of NPs at two le...

introduction: the present study aimed to investigate the microbial quality of the produced vermicomposts and compare them with the existing standards. methods: this experimental study was conducted as a pilot-scale one, in the laboratory school. some perishable domestic waste were mixed in a reactor, including food waste, vegetables and fruits, cow manure and sludge of wastewater treatment plan...

The presence of estrogens in livestock excrement has raised concerns about their potential negative influence on animals and the overall food cycle. This is the first investigation to simultaneously remove estrogens, including estriol (E3), bisphenol A (BPA), diethylstilbestrol (DES), estradiol (E2), and ethinyl estradiol (EE2), from cow manure using a Fenton oxidation technique. Based on the r...

Background and Purpose: The Phytoremediation efficiency of heavy metals is one of the important points in environmental studies. This research was conducted to investigate the effect of cow manure, elemental sulfur, and EDTA on Cd uptake by Indian mustard in a Cd-polluted soil in the presence of Thiobacillus thiooxidans. Materials and Methods: Treatments consisted of applying cow manure (0, 5,...

This study was conducted to evaluate the performance of black gram (Vigna mungo.L) grown under drought stress using coir waste manure and cow dung manure. Two varieties of black gram-ATD mash 3 and ATD mash 1 were the treatment variables. A best fit positive relationship existed between leaf chlorophyll and leaf nitrogen content with two organic manures. N, P and K accumulation in the two varie...
