A holistic approach was followed for utilizing tetracyclines (TCs)-contaminated pig manure, by composting this with rice straw in a greenhouse for CO₂ fertilization and composted residue application. After composting, the composted residues can be applied to cropland as a supplemental source of synthetic fertilizers. The objective of this study was to determine the effect of pig manure-rice str...

ACKNOWLEDGMENTS The project was supported with a grant from the New York State Department of Economic Development, Office of Recycling Market Development (ORMD). Additional support was provided by the New York City Department of Sanitation (DOS) and by the New York City institutions and businesses, and compost technology providers described in this report. II Purpose of the Study Composting is ...

Pilot composting experiments of swine manure with corncob were conducted to evaluate the performance of the aerated static bin composting system. Effects of temperature control (60 and 70 degrees C) and moisture content (70% and 80%) were monitored on the composting by measuring physical and chemical indexes. The results showed that (1) the composting system could destroy pathogens, converted n...

Composting is a robust waste treatment technology. Use of finished compost enables plant nutrient recycling, carbon sequestration, soil structure improvement and mineral fertiliser replacement. However, composting also emits greenhouse gases (GHG) such as methane (CH4) and nitrous oxide (N2O) with high global warming potential (GWP). This thesis analysed emissions of CH4 and N2O during composti...

A primary concern with composting is the lack of knowledge about the fate of widely used pesticides. Also, there is increasing interest in the use of composting as a bioremediation method for soils contaminated with xenobiotics such as TNT, PCBs, chlorophenols and PAHs. We used a laboratory scale composting system to determine the extent of mineralization, incorporation into humic matter, and v...

BACKGROUND Animal manure is a reservoir of antibiotic resistance genes (ARGs) that pose a potential health risk globally, especially for resistance to the antibiotics commonly used in livestock production (such as tetracycline, sulfonamide, and fluoroquinolone). Currently, the effects of biological treatment (composting) on the transcriptional response of manure ARGs and their microbial hosts a...

Composting is an alternative method of carcass disposal in those situations when conventional methods are inadequate. With proper maintenance and monitoring, carcass composting systems can be safe and efficient with minimal environmental impacts. Importantly, proper composting eliminates many pathogens and may reduce levels of carcass contamination with spore-forming bacteria, prions, and other...
