This paper presents an insight into benefits of organic waste recycling through composting over landfill on municipal solid waste management in Phnom Penh, in terms of greenhouse gases (GHGs) mitigation. Future waste generation from 2003 to 2020 was forecasted and four scenarios of organic waste recycling were carried out. Organic wastefood and garden wastewere used for composting and the rem...

environment conservation is the common concern at all levels from local to global. most of the recent environment problems and ill effects stem from ecological misappropriation and neglect to recognize the limits of ecosystem, its. rapid population growth, low income, lowest health facilities, poor sanitation, lack of education. personal and community hygiene poverty has enhanced the incidence ...

Composting is clearly reported as one of the most effective technique to transform organic wastes into an interesting resource, useful to improve soil characteristics and playing a potential role in reducing greenhouse gases, due to its high content in stable organic matter (Favoino and Hogg, 2008). However, its agronomical properties are dependent on several factors, which pollutant contents b...

The treatment of organic waste from household in the Danish-German border region is very diverse, the Danish area only uses incineration for the treatment while the German system includes combined biogas and composting, mechanical and biological treatment and incineration. Data on all parts of the organic waste treatment has been collected including waste composition data and data from treatmen...

Organic wastes under consideration are of natural origin that possess biochemical characteristics ensuring rapid microbial decomposition at relatively normal operating conditions. When considering the organic waste treatment we have generally in mind organic mineralization, biological stabilisation and detoxification of pollutants. Most common organic wastes contain compounds that are mainly we...

Anaerobic digestion of source-separated municipal organic waste is considered feasible in Denmark. The limited hydraulic retention in the biogas reactor (typically 15 d) does not allow full degradation of the organic waste. Storage of anaerobically digested municipal organic waste can therefore be a source of methane (CH4) emission that may contribute significantly to the potential global warmi...

Environmental policies at the European and global level support the diversion of wastes from landfills for their treatment in different facilities. Organic waste is mainly treated or valorized through composting, anaerobic digestion or a combination of both treatments. Thus, there are an increasing number of waste treatment plants using this type of biological treatment. During waste handling a...

As part of environmental management policies in Europe, separate collection of organic household waste and nonorganic household waste has become increasingly common. As waste is often stored indoors, this policy might increase microbial exposure in the home environment. In this study we evaluated the association between indoor storage of organic waste and levels of microbial agents in house dus...

A biotechnology for aerobic conversion of food waste into organic fertilizer under controlled aeration, stirring, pH and temperature at 55-65 degrees C, is proposed. To maintain neutral pH at the beginning of the bioconversion 5% CaCO3 was added to the total solids of the food waste. The addition of 20% horticultural waste compost as a bulking agent to the food wastes (w.w./w.w.), improved the ...
