Abstract The degradability of conventional plastic packaging specimens made from PP and PET, that were produced with novel prodegradant additives, was investigated during biological waste treatment processes. additives merchandised to foster the degradation commodity plastics by enzymatic or abiotic Four different two evaluated for their biodegradability anaerobic aerobic conditions. Aerobic in...

organic fraction of solid waste, which upon degradation produces foul smell and generates pathogens, if not properly managed. composting is not a method of waste disposal but it is a method of waste recycling and used for agricultural purposes. an integrated approach of composting methodology was tested for municipal solid waste management. solid waste first was composted and after 22 days, was...

Copper is one of the most abundant heavy metals present in swine manure. In this study, a laboratory-scale aerobic composting system was amended with Cu at three levels (0, 200, and 2000 mg kg-1, i.e., control, Cu200, and Cu2000 treatments, respectively) to determine its effect on the fate of copper resistance genes [copper resistance genes (CRGs): pcoA, cusA, copA, and tcrB], antibiotic resist...

Lemus, G.R. and Lau, A.K. 2002. Biodegradation of lipidic compounds in synthetic food wastes during composting. Canadian Biosystems Engineering/Le génie des biosystèmes au Canada 44: 6.336.39. Changes in food production, consumption patterns, and more restrictive regulations, result in larger quantities and higher diversity of waste materials that need to be treated and disposed. Organic wastes...

Composting is a reliable technology for production of stabilized organic matter that is suitable for agriculture, but this process should be carefully monitored with appropriate indices. Quality of compost is important from maturity and stability viewpoint, but in most compost factories proper attention is not paid to it. This study was designed to evaluate the stability indices in municipal so...

The chemical composition of hop sediments from beer brewing and fermentation gives them the potential for further use. These wastes are not generated in large amounts, but absence proper characteristics may lead to processing errors. This study examines possibility using waste aerobic biological transformation processes (composting). was carried out on two different technological stages product...

This paper presents preliminary results from a year-long indoor bioaerosol monitoring performed in three working environments of a municipal composting facility treating green and organic waste. Composting, whereby organic matter is stabilized through aerobic decomposition, requires aeration, causing the dispersion of microbial particles (microorganisms and associated toxins). Waste can, theref...

A composting product of marine animal resources has been used as a fertilizer and a soil conditioner in Japan. This compost was produced by a repeated fed-batch fermentation system with three successive aerobic bioreactors. Composting temperature reached about 75 degrees C without heating. The bacterial diversity in this compost was investigated by denaturing gradient gel electrophoresis (DGGE)...

A combination of semipermeable membrane-covered composting systems and greenhouses was used to investigate the effects different insulation on aerobic fermentation mixed raw materials changes in characteristics feedstock. The greenhouse increased peak temperature by 6.53 °C, average 28.2%, extended duration effective high-temperature stage (temperature ≥ 50 °C) 14 days. decomposition percentage...
