AbstractMalaysia is a country that has recorded a phenomenal economic development success story. One of the most important problems is solid waste due to inadequate management practices. This resulted in an increase in the amount of waste generated. The national average in at 0.5-0.8 kg/person/day, but in the cities the figures have escalated to 1.7 kg/person/day. This paper addresses the current practice of solid waste management and its disposal in Malaysia. Currently, the waste management app...

AbstractGroundwater is an important source of drinking water, especially for rural population. In the last years, bacteria, nitrate, organic chemicals and other pollutants existing in groundwater have increased public concern about the quality of groundwater. Groundwater provides about 22% of all freshwater withdrawals; 37% of agricultural use (mostly for irrigation); 37% of the public water supply withdrawals; 51% of all drinking water for the total population and 99% of drinking water for the ...

The concept of collaborative management is considered to be one of the most efficient instruments for sustainable development of some areas, which are under anthropic pressure due to the production of solid waste. The paper stands for the necessity of promoting a collaborative management among the main actors involved in an efficient and sustainable urban solid waste management, in the metropolitan area of Bucharest. The present management is mainly based on the strictly economic vision of manag...

Abstract The amount of bottom ash produced in Italy from municipal solid waste incinerators is estimated at over a million tons per year. Up to now, it has almost all been disposed of in landfills. Therefore, large profit margins, from both the economic and environmental standpoint, can be expected from the recovery of this material, or at least from a fraction of it. In this study, a rapid procedure for the recovery of different bottom ash fractions based on mechanical sorting and aging was...

With population growth and increasing industrialization, enormous amounts of agro-industrial wastes are being produced. Without proper use, these keep piling up leading to tremendous pressure on environmental safety. There is also considerable economic interest not only in the proper utilization of these wastes, but also in developing appropriate processes for this purpose. Sludge generated in pulp and paper mills is one of such solid wastes. Although several studies have investigated its reuse,...

The supply of RM is not only a matter of availability of primary but also of secondary raw materials (SRM). In fact a great amount of waste can be regained as practical and valuable SRM by enhancing the recovery processes from industrial, mining and municipal landfill sites, especially if we consider that Europe is highly dependent on the imports of...

In order to reduce the production of pollutants, it is most important that landfills are adapted to the climatic conditions of the area where they are located. In this sense, there are very few studies focused on how to reduce leachates from landfills in semiarid regions, which are especially sensitive to the impacts that this type of activity potentially has on water resources. The aim of this study is to identify the best type of landfill cover that reduces leachate production in semiarid regi...

Printed circuit boards are the most important component of any electrical and electronic device. The average metal content in waste printed circuit boards is ~30-35% whereas the rest of the material is a non-metal fraction (NMF). Metals in the waste printed circuit boards are recycled for their value whereas the NMF is mostly sent to landfills or incinerators for disposal. The circuit board laminates contain flame retardant chemicals that pose potential hazards to the environment and to public h...
