Solid municipal waste landfills are the third largest source of man-made methane emissions. Methane is one of the greenhouse gases contributing to global warming. The capture of methane emissions in the waste sector is addressed by collecting it and using it for energy production. Methane emissions from active or closed landfills can be reduced by methane oxidation, which is developed as a covering over these landfills. It is usually composed of a gas distribution layer that favours micro-organisms that consume me...

The growing global population is creating high demand for transport and the various goods industries, which produce lead-generating emissions from air pollutants.
