Eff ective management of municipal solid waste (MSW) in Pacifi c developing member countries (DMCs) is diffi cult because of several country-specifi c characteristics. These include limited land area, customary land ownership; environmental fragility; limited human and fi nancial capacity; and in some countries, a heavy reliance on tourism. The challenges mean that selecting technologies that a...

Biochars are produced by low-oxygen gasification or pyrolysis of organic waste products, and can be co-produced with energy, achieving waste diversion and delivering a soil amendment that can improve agricultural yields. Although many studies have reported the agronomic benefits of biochars produced from pyrolysis, few have interrogated the ability of gasified biochars to improve crop productiv...

worldwide, asbestos fibers utilized in fiber cement boards, have been recognized as harmful materials regarding the public health and environmental pollutions. these concerns motivate the researchers to find the appropriate alternatives to substitute the asbestos material towards the sustainability policies. in this paper, the applicability of asbestos replacement with three types of agricultur...

Nitrate is often seen as an agricultural pollutant of groundwater and so is expected to be at higher concentrations in the groundwaters surrounding a city than in those beneath it. However the difference between rural and urban nitrate concentrations is often small, due to the non-agricultural sources of nitrogen that are concentrated in cities. This paper illustrates the source and significanc...

Regarding various types of pollutant, waste management requires high attention.
