This study is proposing a System Dynamics Model for estimating Greenhouse Gas (GHG) emission from treating Municipal Solid Waste (MSW) in South Korea for years 2000 to 2030. The government of country decided to decrease the total GHG emission from waste sector in 2030 as per Business-as-usual level. In context, four scenarios are generated to predict GHG emission from treating the MSW with three processes i.e., landfill, incineration and recycling. For prior step, MSW generation rate is projected for present and future case using population and waste generation per capita data. It is found that population and total MSW are directly correlated. The total population will increase to 56.27 million and total MSW will be 21.59 million tons in 2030. The methods for estimating GHG emission from landfill, incineration and recycling are adopted from IPCC, 2006 guidelines. The study indicates that Scenario 2 is best to adopt for decreasing the total GHG emission in future where recycling waste is increased to 75% and landfill waste is decreased to 7.6%. Lastly, it is concluded that choosing proper method for treating the MSW in country can result into savings of GHG emission.

Solid Waste Incinerator

Sludge disposal is becoming an issue at the municipal solid waste incinerator (MSWI), especially for environmental and economic reasons. This paper describes a case study of the optimization of the sludge management (SM) system at the MSWI in the Czech Republic. The original concept of SM at MSWI was designed as waste-free. However, the present operation indicates that there is a need to carry out regular extraction and disposal of sludge settling at the bottom ash tank and the bottom of the retention basin. The current status of SM causes problems not only in terms of operation but it also entails significant financial costs given the necessary regular cleaning of tanks. The aim of the applied research presented in this paper is SM optimization by a mobile sludge dewatering (DW) press unit with optimal polymer combination for DW.

Anaerobic digestion has emerged as the preferred treatment for organic fraction of municipal solid waste. Digestate management strategies are devised not only for safe disposal but also to increase the value and marketability. Regulations and standards for digestate management are framed to address the pollution concerns, conserve vulnerable zones, prevent communicable diseases, and to educate on digestate storage and applications. Regulations and the desired end uses are the main drivers for the enhancement of digestate through pretreatment, in vessel cleaning, and post-digestion treatment technologies for solid and liquid fractions of digestate. The current management practice involves utilization of digestate for land application either as fertilizer or soil improver. Prospects are bright for alternative usage such as microalgal cultivation, biofuel and bioethanol production. Presently, the focus of optimization of the anaerobic digestion process is directed only towards enhancing biogas yield, ignoring the quality of digestate produced. A paradigm shift is needed in the approach from ‘biogas optimization’ to ‘integrated biogas–digestate optimization’.

Barriers And Challenges

The rapid industrialization, continuous economic development, as well as increasing urban population and peoples living standards in Urumqi have resulted in a great increase of the total generated amount of municipal solid waste (MSW). Urumqi government strives to improve its municipal solid waste management (MSWM), and the MSW safe disposal rate was already up to 92.9% in 2011. This study presents an detailed overview on current MSWM practice in Urumqi municipality, including MSW characteristics and current status of MSW generation, collection, transportation and final disposal. It shows that more than 80% of MSW was final disposed by landfill and current landfill based MSWM system lack of effectiveness and efficiency. The major barriers and challenges that inhibit effective and efficient MSWM are imperfectness and inefficient enforcement of relevant policies, inappropriate waste treatment fee system, backward technology, insufficient public education and participation, as well as lack of fundamental research. Finally, to overcome such barriers, we propose a detailed integrated MSWM system to facilitate MSWM in Urumqi.

The increasing anthropogenic activities as a result of significant growth in population, urbanization, and industrialization has resulted in a tremendous amount of municipal solid waste (MSW). The municipal authorities are under extreme pressure from the epidemiological evidence towards human and environment as a result of injudicious waste disposal to landfills without any material recovery. In this article, the current status and limitations in treating MSW by the developing countries have been overviewed with a case study from Peshawar-Pakistan. The daily waste production in Peshawar city is about 650.8 tons with 0.4 kg/capita/day. Among the total waste, food waste contributes 14.3% fallowed by plastic waste (4%), paper (2.7%), glass (1.2%), wood (1.1%) and metals/rubber (0.6%). The waste collection efficiency is very low and about 40% of waste are collected whereas 60% of the waste remains in streets or at collection points. Currently there well-organized and specialized waste management practices such as composting, incineration, gasification, pyrolysis, biological treatment, and recycling for treating waste according to environmental deliberation. The directives of the developed countries had strictly imposed the regulations to increase the waste recycling and material recovery whereas in the developing countries the lack of proper legislation, planning, awareness regarding waste reduction has worsened the municipal solid waste-related problems. Moreover, in this article, an attempt has been made towards various important steps that need to incorporate in formulating the strategy for sustainable MSW management along with various aspects for their assessment in term of their sustainability in the developing countries.
