Abstract: It is well known that due to finite resources and impact of conventional fossil fuel on the environment led to find sources and to secure renewable/sustainable energies globally that would provide uninterrupted clean energy and be competitive to the present power generation using conventional energy sources. Many of the developed and developing countries invested reasonable amounts of their energy budgets in developing technologically and economically feasible solar, hydro and wind turbines. In comparison, not a great deal of work is done on energy from the waste in many of the developing countries, including PNG. The energy from the waste could be in the form of a proper management of municipal solid waste (MSW), animal waste and vegetation that would provide many benefits, such as (1) production of biogas, chiefly methane, (2) separation of recyclables from the waste, (3) minimization of landfill volume, harmful bacteria growth and environmental pollution, (4) enrich the agricultural land with fertilizers. The focus of this study is to review the work done by previous workers on converting municipal and other waste to energy. The challenges are to identify a form of major sustainable energy that would be affordable, community friendly and would emit minimum toxic gases to the environment. It is believed that the findings of this paper would be beneficial to policy makers and researchers. An experimental analysis was conducted using animal waste from a local farm adjacent to the university. A custom made simple anaerobic digestor was used for this purpose. The results obtained confirmed considerable recovery of methane, that is sustainable and promising for community use. |
Keywords and phrases: municipal solid waste (MSW), biogas, aerobic digestion (AD), energy.
