Organic Waste Generation and Its Valorization Potential through Composting in Shashemene, Southern Ethiopia

Valorization of Organic Wastes by Composting Process and Soil Amendment

Composting barrel for sustainable organic waste management in Bangladesh.

To ensure quick and uniform aerobic stabilization of biowaste through domestic composting and to prevent malodorous emissions, two modifications were made to a conventional steel barrel composter by: (1) providing 0.0125 m diameter openings throughout the sides and (2) placing a 0.0254 m diameter perforated polyvinyl chloride (PVC) pipe in the middle portion of the barrel. The volume of compost...

Valorization of Beer Brewing Wastes by Composting

The aim of this work was to study the viability of recycling the residual yeast and diatomaceous earth (RYDE) slurry generated by the beer brewing industry by composting with animal manures, as well as to evaluate the quality of the composts obtained. Two pilot composting trials were carried out with different mixes: cow manure/RYDE slurry (Pile CM) and sheep manure/RYDE slurry (Pile SM). For a...

Collecting water: Shashemene, Ethiopia, November 2015

A water point was installed in 2012 as part of a biogas development initiative in an informal urban community of 200 households. The facility provides sanitation, gas for cooking, and organic fertiliser. It consists of four latrines and an inlet for animal waste, a fermentation chamber where the biogas (methane) is produced, and a communal kitchen with four stoves. The slurry byproduct is rende...

Evaluation of an Organic Waste Composting Device to Household Treatment

The performance of a plug-flow automated aerobic digester used with the compost of the Biodegradable Organic Waste (BOW) from a typical family at its generation rhythm was evaluated. During a 13 month assessment, 179.7 kg of BOW were treated and 106.7 kg of compost were obtained with a C:N ratio of 12 and an average concentration of N of about 2.72%. Additional tests enabled to assess the gener...
