Abstract
Semi-aerobic filling is being utilized in this project with the aim of reducing greenhouse gas emissions at a landfill site in Malaysia and establishing the early stages for overall improvement of the plant environment through the addition of a ventilation facility.
The project is designed to improve the landfill site, currently in an anaerobic condition, to a semi-aerobic condition by installing a ventilation facility that uses a steel pipe-casing method. This will curb the quantity of methane gas being emitted from the landfill site.
Implementing this project will provide benefits that include the reduction of gas emissions, such as CH4 and hydrogen sulphide, from the landfill site as well as a lessened environmental impact. The risk of explosions and toxic gas generation at the landfill site will also be eliminated. With the expansion of the aerobic area, the degradation of wastes will be accelerated and the impact of leachate on the ambient environment will be decreased due to improved leachate discharge. Safe closure of the landfill site will also be achieved quickly.
