When addressing the problem of sand scarcity in the case of Jakarta wher...

This paper examines waste prevention – the “reduce, reuse” part of the solid waste management hierarchy. It summarizes research findings on prevention – some generated as background papers in 2007 as part of DEQ’s Waste Prevention Strategy development — and supplements with a more recent literature review. DEQ’s Waste Prevention Strategy is also summarized. This paper concludes with a status re...

environmental degradation is not only well advanced already, but also is getting progressively worse as the countrys population, urbanisation and industrialisation increase, and as its economy develops generally. This concern has led to a growing recognition that economic development and the health and well-being of the countrys population are closely linked with improved environmental manageme...

Management of municipal solid waste (MSW) has become a significant environmental problem, especially in fast-growing cities. The amount of waste generated increases each year and this makes it difficult to create solutions which due to the increase in waste generation year after year and having to identify a solution that will have minimum impact on the environment. To determine the most sustai...

Megacities concentrate large amounts of people, absorb a large quantity of resources and generate vast amounts of waste and sewage, thereby contributing considerably to the use of the environment as a sink. The quantity of resources consumed and urban residues produced per capita tend to rise steadily with increased per capita income. Proper management of municipal solid waste is critical to th...

BACKGROUND Medical establishment such as hospitals and research institutes generate sizable amount of hazardous waste. Health care workers, patients are at risk of acquiring infection from sharps and contamination of environment with multiple drug resistant microorganisms if wastes are not properly managed. OBJECTIVES To characterize types and evaluate waste disposal techniques employed in th...

A steam autoclave was used to sterilize bacteria in clinical solid waste in order to determine an alternative to incineration technology in clinical solid waste management. The influence of contact time (0, 5, 15, 30 and 60 min) and temperature (111 °C, 121 °C and 131 °C) at automated saturated steam pressure was investigated. Results showed that with increasing contact time and temperature, th...
