Paper Abstract:	Papua New Guinea has an estimated population of 8 millions in 2015, out of which 13% lives in urban areas. It is estimated that in 2050, 22.7% of the total population would live in urban area [United Nations, 2015]. PNG has about 580MW of installed generation capacity such as hydropower (40%), diesel (37%), gas fired (14%) and geothermal (9%). At present, roughly 85% of the population do not have access to energy and multiple factors may be associated with it such as affordability of prices, reliability of supply, and energy security. One of the problems identified in regard to supplying energy to general stake holders is the accumulation of costs and resources involved due to the general inaccessibility and rugged terrain of much of PNG [PNG NEP 2015]. The PNG government is emphasising for increasing the share of renewable energy sources into the total energy produced. Thus, the focus of this study is to identify a form of sustainable energy at an affordable cost that is community friendly and can use sustainable materials available in rural or urban area. This could be in the form of a proper management of Municipal Solid Waste (MSW) from Lae, second most important industrial city after the capital city, Port Morseby. The MSW may include animal waste and food waste as well, would provide many benefits, such as i. ferrous, aluminium, glass etc separated from the waste and recycled for further use. ii. organic materials fed in Anaerobic Digesters for conversion to bio gas, chiefly methane that may be used for community cooking's or can be converted into electricity. iii. by products of Anaerobic Digestion process would yield fertilizers that can be used to enrich agricultural land. iv. minimised of landfill volume, release of toxic gases to the environment and formation of uncontrolled harmful bacteria growth. To the best of knowledge of the author, no effective data exists on the amount of solid municipal wastage or composition of the wastage collected periodically by the local municipality from Lae households. Nor data is available on the capacity of the landfills in Lae. This paper will conduct a review of work done by previous researchers in managing solid waste and investigations would be conducted in extracting sustainable energy from the solid waste that could be useful for the stake holders such as animal/poultry firms and rural regions of developed and developing countries.
