TL;DR: In this article, the potential application of waste-to-energy technology via the production of biogas from animal waste as an alternative source of power generation in Indonesia is highlighted. And several key technologies on how to utilize waste for power generation are presented.
Abstract: The implementation of waste to energy technology such as the production of biogas from animal waste has been considered as one of the best means to achieve sustainable energy development goals in many developing countries including Indonesia. In the past several years, the rapid increment in the number of animal husbandries in Indonesia could potentially provide a considerable amount of feedstock for the generation of biogas. Therefore, this article is aimed at highlighting the potential application of waste to energy technology via the production of biogas from animal waste as an alternative source of power generation in Indonesia. Here, Indonesia's energy mix and several issues regarding waste management is comprehensively reviewed. Additionally, this article also discusses the current status in Indonesia's energy generation from new and renewable resources, especially from waste. Hence, several key technologies on how to utilize waste for power generation are presented. Based on the analyses, numerous opportunities could be explored in terms of turning animal waste to energy by biogas production in Indonesia. It is estimated that about 9597.4 Mm3/year of biogas could potentially be generated from animal waste in Indonesia. This large amount of biogas production could be utilized to generate electric power up to 1.7 × 106 KWh/year. Finally, this paper also highlights several main challenges faced in the implementation of large-scale biogas production in Indonesia.

TL;DR: A critical review of various technologies, with their updated progress, involved in the exploitation of MSW as a renewable resource, along with the critical advantages and limitations on energy and material cycling for sustainable MSW management is presented in this article.
Abstract: Municipal solid waste (MSW) management has emerged as probably the most pressing issue many governments nowadays are facing. Traditionally, Waste-to-Energy(WtE) is mostly associated with incineration, but now, with the emergence of the bioeconomy, it embraces a broader definition comprising any processing technique that can generate electricity/heat or produce a waste-derived fuel. Under the ambit of the circular economy many nations are looking for, additional effort must be made to be sure of acquiring the most updated information and paving a sustainable path for managing MSW in such a frame. In this regard, we have undertaken a critical review of various technologies, with their updated progress, involved in the exploitation of MSW as a renewable resource, along with the critical advantages and limitations on energy and material cycling for sustainable MSW management. Incineration, the most widely used method, is nowadays difficult to further apply due to its dubious reputation and social opposition. Meanwhile, to address the organic fraction of MSW which currently is mostly unrecycled and causes disposal issues, the biological approach presents an attractive option. The new emphasis of bioeconomy leads us to understand how environmental biotechnologies should be better connected/integrated for more sustainable MSW management. This article is concluded with advances of future prospects, which can serve as a timely reminder to encourage competent authorities/researchers to work towards further improvement of the present MSW management system.

TL;DR: In this paper, a comprehensive review of municipal solid waste generation and its characteristics is presented, providing a bird's-eye view of the suitability of various technologies for energy production, providing up-to-date information about it.
Abstract: Solid waste treatment and disposal is a global challenge for the development of a sustainable society. The problem has been exacerbated by a rise in waste products as a result of population growth and urbanization. Ever-increasing municipal solid waste, together with its high proportion of organic waste and its unscientific disposal, contributes to Greenhouse gas emissions and other air pollutants. Municipal solid waste (MSW) mismanagement not only has harmful environmental consequences but also poses public health risks and raises other socioeconomic concerns. The mitigation approach requires an environmentally sustainable interpretation of the waste for its management and treatment. The waste-to-energy conversion provides a solution to environmental issues such as Greenhouse gas emission and waste management, thereby helping to achieve a green environment with a simultaneously prospering economy. This paper provides a comprehensive review of municipal solid waste generation and its characteristics. It provides a bird's-eye view of the suitability of various technologies for energy production, providing up-to-date information about it. It also covers challenges and perspectives in this field of research.

TL;DR: In this paper, the authors estimate that the amount of municipal solid waste (MSW) generated by urban populations is growing even faster than the rate of urbanization and that by 2025 this will likely increase to 4.3 billion urban residents.
Abstract: Solid waste management is the one thing just about every city government provides for its residents. While service levels, environmental impacts and costs vary dramatically, solid waste management is arguably the most important municipal service and serves as a prerequisite for other municipal action. As the world hurtles toward its urban future, the amount of municipal solid waste (MSW), one of the most important by-products of an urban lifestyle, is growing even faster than the rate of urbanization. Ten years ago there were 2.9 billion urban residents who generated about 0.64 kg of MSW per person per day (0.68 billion tonnes per year). This report estimates that today these amounts have increased to about 3 billion residents generating 1.2 kg per person per day (1.3 billion tonnes per year). By 2025 this will likely increase to 4.3 billion urban residents generating about 1.42 kg/capita/day of municipal solid waste (2.2 billion tonnes per year).
