BACKGROUND AND OBJECTIVES Dengue is an important public health problem in Yogyakarta city, Indonesia. The aim of this study was to build an innovative community-centered dengue-ecosystem management intervention in the city and to assess the process and results. METHODS For describing the baseline situation, entomological surveys and household surveys were carried out in six randomly selected ...

Background Environmental regulations on medical waste incineration have become more stringent at the same time as landfill capacities are diminishing in many parts of the country. These two circumstances are leading many healthcare facilities to reevaluate their medical waste generation and disposal practices. Although the typical healthcare waste stream can include infectious, radioactive, and...

Gasification technology is by no means new: in the 1850s, most of the city of London was illuminated by "town gas" produced from the gasification of coal. Nowadays, gasification is the main technology for biomass conversion to energy and an attractive alternative for the thermal treatment of solid waste. The number of different uses of gas shows the flexibility of gasification and therefore all...

Disposing of sewage sludge in an economical and environmentally acceptable manner is a problem for all communities that have wastewater treatment plants , Similarly , many com­ munities are having to dispose of increasing quantities of solid waste. These problems could be solved by co-disposal of sludge and solid waste in a common facility. This study , .‘nvnH .. --­ au­ &LLnAE -' .‘maL­nH .. o...

Plastics wastes from a municipal solid waste (MSW) plant have a high-energy content and are suitable for fuel generation. Thermal cracking is one of the possible ways to obtain petrochemical feedstock from polymer wastes. Municipal waste plastic of LDPE conversion to kerosene grade fuel experiments were carried out under atmospheric conditions at temperatures between 150 ̊C and 420 ̊C. Low densit...

The aim of the study was to investigate the impact of municipal solid waste incinerator (MSWI) bottom ash (BA) codisposed with municipal solid waste (MSW) on landfill stabilization according to the leachate quality in terms of organic matter and nitrogen contents. Six simulated landfills, that is, three conventional and three recirculated, were employed with different ratios of MSWI BA to MSW. ...

BACKGROUND Biomass and municipal solid waste offer sustainable sources of energy; for example to meet heat and electricity demand in the form of combined cooling, heat and power. Combustion of biomass has a lesser impact than solid fossil fuels (e.g. coal) upon gas pollutant emissions, whilst energy recovery from municipal solid waste is a beneficial component of an integrated, sustainable wast...

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 ...

The management of medical waste is of great importance due to its potential environmental hazards and public health risks. In the past medical waste was often mixed with municipal solid waste and disposed of in residential waste landfills or improper treatment facilities (e.g. inadequately controlled incinerators) in Korea. In recent years, many efforts have been made by environmental regulator...
