Landfill methane oxidation using biocover under laboratory conditions / Siti Aishah Kamarul Baharain

Generation of waste continues to increase in response to rapid population growth. An estimated 10 million tonnes of total waste was produced in 2008 in Malaysia which was sent to 260 landfills. Malaysian landfills produce 1.3-7.5 L/kg/year of methane gas. Landfill gas consists mainly of methane (55%...

An estimated 10 million tonnes of total waste was produced in 2008 in Malaysia which was sent to 260 landfills. Malaysian landfills produce 1.3-7.5 L/kg/year of methane gas.

Meanwhile the Rp (potential oxidation rate) value for compost (17.036 mL/d) was almost double the value for black soil (10.806 mL/d).
