Estimation of landfill gas production and potential utilization in a South Africa landfill

Abstract

The methane emitted from the Polokwane landfill estimated from LandGEM and Afvalzorg models will peak in year 2023 at 4613 Mg/year and 3128 Mg/year, respectively. Also, the total methane emissions from the year 1999 to 2050, are 111,799.25 Mg/year and 27,898.93 Mg/year for both LandGEM and Afvalzorg models, respectively. The LFGcost web model simulations showed that the implementation of a LFG utilization project using Microturbine and CHP microturbine engines are economically feasible. This is considering the sales of electricity to the people. Therefore, implementation of LFG utilization is economically feasible from sales of electricity generated and Certified Emission Reductions.
