Background: The biogases are the mixture of gases produced through the microbial decomposition of organic waste which are amply observed in the landfills. The main purpose of this study was to estimate the emission rates of landfill gases such as carbon dioxide, methane and non-methane organic compounds (NMOCs) in the solid waste landfill of Rodan city in Hormozgan province. Methods: A...

Unlike that of western countries, the solid waste of Asian cities is often comprised of 70-80% organic matter, dirt and dust. Composting is considered to be the best option to deal with the waste generated. Composting helps reduce the waste transported to and disposed of in landfills. During the course of the research, the author learned that several developing countries established large-scale...

Solid-waste treatment in space for Advanced Life Support, ALS, applications requires that the material can be safely processed and stored in a confined environment. Many solid-wastes are not stable because they are wet (40-90% moisture) and contain levels of soluble organic compounds that can contribute to the growth of undesirable microorganisms with concomitant production of noxious odors. In...

A pilot study was conducted to assess the feasibility of composting of source separated organic matter of municipal solid waste (MSW) generated in low, middle and high income areas of Karachi city with a population over 14 million. Results of MSW analysis indicate the presence of high percentage of biodegradable organic matter (71-74%), acceptable moisture content (40-50%) and C/N ratio (38-40:...

This paper investigates the feasibility of processing the organic fraction of the municipal solid waste from the Winchester, Southampton, Eastleigh and wider areas (population ~450,000) using anaerobic digestion. Commercial and agricultural organic waste is also considered. Data for feedstock location, volumes and type is collated from many information sources. A model is used to estimate the e...

1 This paper presents a study to evaluate the recently developed enzymatic 2 hydrolysis test (EHT) through its repeated application to a waste treatment process. A 3 single waste treatment facility, involving a biodrying process, has been monitored using 4 three different methods to assess the biodegradable content of the organic waste fractions. 5 These test methods were the anaerobic BMc, aer...

This study has analyzed the generation and characteristics of solid waste in Dhaka city, along with the associated environmental impacts and existing solid waste management practices. Special focus was given on the effect of composting on final disposal of solid waste and effect of landfill site location on transportation cost. An estimate of the future generation rate indicates that the presen...
