“…Seelong landfill is the first clean development mechanism (CDM) project in Malaysia and one of the 14 landfills in Johor state. It captures about 10,000 tons of LFG per year (25% of generated capacity) for flaring [7,8]. However, flaring is the least desirable way of LFG emission control -LFG utilization for renewable energy production is the state-of-the-art technology.…”

Landfill gas (LFG) is a mixture of gases mainly CH4 and CO2 which are the most problematic of the greenhouse gases (GHGs) due primarily to their highest rate of accumulation in the environment. These two main GHGs are emitted from most landfills in developing countries. As a mitigation measure, the gases can be collected and utilized as renewable energy source. This research therefore aimed at planning the utilization of LFG for renewable energy production using linear programing approach executed in general algebraic modeling system (GAMS) and applied to Seelong landfill in Johor, Malaysia as the case study. GAMS (the optimizer) selects the most profitable LFG utilization technology from a number of options such as: gas engine, gas turbine and steam turbine for electricity or combined heat and power production; steam boiler for steam production; direct LFG distribution to residences/industries as substitutes to natural gas. The results from the optimizer gave a maximum profit of USD2.54 million per year. This included revenues from product sale and carbon credit. The results also revealed that GHG reduction of about 9,000 tons CO2eq were accomplished, and thus this is environmentally and economically beneficial environmentally (in terms of carbon credit). Furthermore, the optimization results revealed that steam turbine running on low grade LFG is the most feasible option in terms of profitability and environmental consideration. This approach can be applied to any sanitary landfill as a means of simultaneously curbing GHG emission and generating revenue.

“…1) was taken to be 10,000 tons per year. This figure was based on the work of Reference [8] in which LFG estimation was made for Seelong landfill and all other landfill sites in Johor state. The product per ton input material and emission reduction potentials for various technologies are shown in Table 1.…”

“…After the gas is converted to electricity, a dedicated line is used to deliver the electricity to utilities. Interconnection usually includes metering equipment necessary to monitor sales and system protection equipment with emergency shutdown capability to prevent either party from damaging the other's equipment, or operations, or injuring personnel [20][21][22][23][24].…”

“…But vigorous efforts are continuing to be made even as the problem is actually increasing in magnitude and complexity rather than getting even partially solved [15,22,98,103,166,196]. The focus in recent years has been on generating energy from MSW, besides material recovery [16,20,63,113,200,204]. The hope that a 'clean and sustainable solution to the MSW problem (and the E-waste problem)' is around the corner continues to be expressed [116,175,186].…”

Background: Any manner of development can be sustainable only if the waste generated by it is not allowed to accumulate but is fully reused/recycled/recovered. Among the strategies to attain this goal have been the attempts to recover energy from municipal solid waste (MSW). About 60% of MSW is carbonaceous, consisting of materials which can either be biodegraded into fuels like methane or incinerated, thereby generating utilizable energy. MSW also contains several components-like metallic scrap and glass pieces-which can be reused or recycled, thereby achieving energy conservation. Given these attributes, MSW appears to be a potential source of energy and resources. Indeed, this belief that MSW is usable if only we try sincerely enough to do so prompts most of us to keep generating much more MSW than is warranted. But how realizable really is the energy potential of MSW? What perils loom into view when we actually set out to utilize MSW as an energy source? The present study addresses these crucially important questions. Methods: The work is based on a critical content analysis of the prior art. Results: The generation of MSW has consistently outpaced the world's efforts to dispose of it cleanly, and the energy (and material) recovery from MSW is easier said than done. In most instances, what is technically feasible is economically unfeasible. And what is economically feasible-such as setting the waste on fire as is often done in developing countries-is exceedingly harmful to the environment and the human health. Measures such as sanitary landfilling and incineration create as many new problems as the old ones they solve. Moreover, despite the use of these less-than-adequate technologies, a major portion of MSW generated in the world lies untreated. Conclusions: As the MSW output is expected to double by 2025, this situation is only set to become worse. Rising tides of E-waste would compound the problem even further. Hence, enormous stress should be put on the reduction of MSW generation by controlling wanton consumerism and wastage, rather than continuing with it in the false hope that technology will soon provide a magical solution and eliminate the problem.
