At present, the main contributors to waste to energy are municipal solid waste, manufacturing waste and landfill gas. Probably we are all most familiar with the first (MSW), which involves the garbage that the garbage men pick up regularly at our homes and which goes to a landfill, a transfer station, or incinerator. Today we are going to introduce you to something relatively new on the alterna...

The present work conducts a preliminary techno-economic feasibility study for a single municipal solid waste mass burning to an electricity plant for the total municipal solid waste potential of the Region of Eastern Macedonia - Thrace, in Greece. For a certain applied and highly efficient technology and an installed capacity of 400,000 t of municipal solid waste per year, the available electri...

Since the start of the second Palestinian uprising (Al-Aqsa Intifada), and due to the Israeli activities, curfews, closures, and military checkpoints imposed since 2000, the quality of social services rendered by Nablus city has been gradually deteriorating. Solid waste management in Nablus city was badly affected by these conditions, and this situation is negatively affecting health and damagi...

The goal of sustainable management of municipal solid waste (MSW), integrated planning required by financial support to control the situation. Life cycle assessment, categorisation, recycling of wastes and proper landfilling are required.

This paper seeks to describe the overall state of Rural Solid Waste Management (RSWM) in China in three main areas: waste collection services, waste transportation services and waste disposal services. Given China’s urbanization, industrialization, and the subsequent improvement of household living standards, the amount of solid waste generated in rural China has increased rapidly. Based on pri...

This paper presents findings of a study, which was carried out in Dar es Salaam city to assess postprivatisation of solid waste collection and disposal. Prior to the assessment, fieldwork studies indicated that current solid waste generation rate in the city is 0.4 kg/cap/day and total waste generation is within the range of 2425 tons/day. This study also indicated that out of the total waste g...

Purpose – The purpose of this paper is to examine the discharge volume of domestic solid waste in rural China and to explore the potential impact of various factors that contribute to it. Design/methodology/approach – The data used in this study come from a large-scale field survey conducted in six Chinese provinces. Based on the collected survey data, econometric model on the determinants of d...

Protection of the environment from solid waste hazards is becoming a serious problem. Different laws and legislations had been put into practice for this purpose. The effect of solid waste in developing countries with limited financial and natural resources and high population growth rate is more severe. To overcome these difficulties, prudent management system for solid waste is required. Furt...

BACKGROUND The aim of this study was to determine the potential of produced compost from the sludge of wastewater treatment plant using earthworms and compare it with the vermicompost produced from household solid waste. METHODS In the current study, three treatments with the same conditions in terms of organic wastes type were prepared to produce vermicompost from household solid waste and s...
