Introduction: Landfill siting is a difficult, complex, and protracted process, which requires evaluating different criteria. A suitable site should be located to dispose the municipal solid wastes hygienically (sanitary landfill), which is one of the fundamental subjects related to the environmental stability of the human settlements. The aim was to select a suitable waste disposal area using f...

Piyungan landfill is the biggest in Special Region of Yogyakarta, Indonesia, which receives municipal solid waste (MSW) from two districts and a city, while its designed service time has been over faces operational obstacles. Meanwhile, volume MSW grows rapidly exceeds reduction rate their sources. The difficulty finding new area reason why appropriate technological alternatives management are ...

Extensive non-engineered landfilling practice in developing countries has raised environmental concerns, but operating a sanitary landfill appears infeasible due to financial incapability. This study aims determine the feasibility of project by including its values into appraisal while simultaneously applying three policy-relevant methods—non-market valuation, benefits transfer, and cost-benefi...

F or years, the Halliburton Company followed local standards in its management of Brazil's state-owned oil company in Catu. This meant discharging stormwater runoff and wastewater effluents directly into the Catu River, untreated. Then, in 1994, the Dallas, Texas-based energy and engineering company initiated new company-wide environmental standards. In Catu, that meant an effort to reduce the ...

In this study the concept of biofilm accumulation in the sand column was promoted to assess the changes in hydraulic conductivity and concentration of organic contaminants of the synthetic leachate. Four different combinations of column study were carried out using synthetic leachate as a substrate solution. Mixed and stratified mode of experiments with two different sizes (0.3 mm and 0.6 mm) o...
