The development and implementation of a solid waste management program served to build local capacity in San Mateo Ixtatán between 2002 and 2003 as part of a public health action plan. The program was developed and implemented in two phases: (1) the identification and education of a working team from the community; and (2) the completion of a solid waste classification and quantification study....

The solid waste residues from olive oil mills constitute an environmental threat if disposed of in the natural environment, as it is common practice in many areas. This review summarizes the efforts of the scientific and technical community to develop appropriate technologies for the valorization of these wastes. The majority of the research towards this purpose focuses on the recovery of high-...

The conventional landfilling does not promote sustainable waste management due to uncontrolled emissions which potentially degrade the environment. In this regard, pre-treatment of municipal solid waste prior to landfilling significantly enhance waste stabilization and provides various advantages. So in this regard pre-treatment methods of municipal solid waste were investigated. The major obje...

sanitary landfills, created for the disposal of solid waste, usually are developed into parks afterthey are closed. however, soil amelioration with organic matter is usually needed to restore fertility andpromote revegetation. sewage sludge creates a massive waste disposal problem. the use of composted sewage sludge (biosolid) as a soil conditioner might restore the soil fertility at landfill s...

In order to take advantage of heat released during composting, the autothermal drying process requires the maintenance of adequate air flow combined with temperature. The aim of this paper was to construct a drying tunnel enabling the automatic control and regulation of the basic process parameters for biomass drying (organic fraction of municipal solid waste together with plant structural mate...

This paper reviews pretreatment techniques to enhance the anaerobic digestion of organic solid waste, including mechanical, thermal, chemical and biological methods. The effects of various pretreatment methods are discussed independently and in combination. Pretreatment methods are compared in terms of their efficiency, energy balance, environmental sustainability as well as capital, operationa...

Introduction: Nowadays, advancements in industries, technology and human welfare level have lead to accumulation of solid wastes and have endangered environmental health. Incorrect waste management intensifies this problem. Recycling and composting (transformation of organic waste to humus) are the most important ways in waste management. Health and safety of the compost is an important issue b...

A lab-scale leaching bed reactor (LBR) was operated to (1) investigate the potential of in-vessel solid-state anaerobic digestion of the organic fraction of municipal solid waste (MSW) and (2) examine the feasibility of using LBRs for hydrolysis/liquefaction and acidification of organic fraction of MSW for maximum total volatile fatty acid (tVFA) and alcohol production. A hydrolysis efficiency ...
