The generation of municipal solid waste is increasing year by year and there are many options for handling and disposing of these wastes. Currently in United States land disposal is the most common practice to deal with municipal solid wastes. The evolution of waste generation, and increase in population suggest composting as a future alternative. Since municipal solid waste comprises of a high...

Hazardous organic and metallic residues or by-products can enter into plants, soils, and sediments from processes associated with domestic, municipal, agricultural, industrial, and military activities. Handling, ingestion, application to land or other distributions of the contaminated materials into the environment might render harm to humans, livestock, wildlife, crops, or native plants. Consi...

Municipal solid waste (MSW) in the Accra region of Ghana has created need for innovative ways to deal with management crises facing city. The goal this study is use analytical hierarchy process (AHP) select an appropriate waste-to-energy (WtE) technology Accra. AHP methodology used assess four WtE technologies, namely landfill biogas, incineration, anaerobic digestion, and aerobic composting. T...

Composting is an appropriate management alternative for municipal solid waste; however, our knowledge about the microbial regulation of this process is still scare. We employed metaproteomics to elucidate the main biodegradation pathways in municipal solid waste composting system across the main phases in a large-scale composting plant. The investigation of microbial succession revealed that Ba...

isposal of wastewater sludge has D long been a problem in wastewater treatment. In the past decade, however, conventional sludge disposal methods, such as incineration, Ocean dumping and landfilling, have come under increasingly tighi regulatory control. These regulatory cmtrols, coupled with increased energy costs and environmental concerns, have sparked renewed interest in wastewater sludge c...

The use of wooden crates for composting a mixture of 70% grass, (Digitaria decumbens), and 30% coffee pulp, combined with 2% Ca(OH)(2), was studied as a method for preparing substrate for the cultivation of Pleurotus ostreatus. Crate composting considerably modified the temperature pattern of the substrate in process, as compared to pile composting, where lower temperatures and less homogeneous...

An environmental assessment of the management of organic household waste (OHW) was performed from a life cycle perspective by means of the waste-life cycle assessment (LCA) model EASEWASTE. The focus was on home composting of OHW in Denmark and six different home composting units (with different input and different mixing frequencies) were modelled. In addition, incineration and landfilling was...

Composting has been used to dispose of animal mortalities and infected materials, such as manure feed, during major disease outbreaks. In this study, we adapted the plastic-wrapped mortality composting system developed by Canadian Food Inspection Agency 2004 highly pathogenic avian influenza outbreak compost swine mortalities. The goals study were evaluate performance field test its ability eli...

Abstract Antibiotic resistance genes (ARGs) have been diffusely detected in several kinds of organic solid waste, such as livestock manure, sludge, antibiotic fermentation residues, and food thus attracting great attention. Aerobic composting, which is an effective, harmless treatment method for waste to promote recycling, has identified also aid ARG reduction. However, the effect composting re...

Per- and polyfluoroalkyl substances (PFAS) have gained increasing attention due to the potential health risks that they present. Secondary sludge biosolids are known as notable PFAS emission routes environment. In this study, partitioning behavior of 14 were investigated across four secondary wastewater treatment types (activated sludge, trickling filter, biological nutrient removal, rotating c...
