For the municipal solid waste (MSW) to be used in a proper way, it is necessary to implement clean technologies capable of thermal treatment of MSW and RDF in order to produce heat and electricity while meeting current ecological requirements. Nowadays, a number of technologies for MSW/RDF thermal treating are being used worldwide. Among them, the most proven technologies, applicable for industrial introduction, have been considered while analyzing their advantages/ disadvantages accounting for local conditions of Ukraine.

Msw Composition

Municipal Solid Waste (MSW) disposal has become an increasingly serious problem in many parts of the world. In general, greater economic prosperity and a higher percentage of urban population correspond to a greater amount of solid waste produced. However, less effort has been exerted in the proper management of solid wastes produced by urban dwellers, particularly in developing countries. This chapter introduces the basic MSW rules. MSW composition, production, and collection are also highlighted. Furthermore, the concept of landfilling and waste decomposition is discussed in this chapter.

Process Operation

This paper presents the development of a novel solid-phase methane fermentation process involving acidic bioleachate production from an organic bed and biomethanation of the bed-liquefaction products in an external methane digester. Process operation with municipal solid waste showed that about 81 percent of the biodegradable volatile solids (VS) could be stabilized during three months of batch operation to afford a methane yield of 0.21 std m3 / kg VS added under ambient (∼25°C) conditions; this compares favorably with an ultimate mesophilic (35°C) methane yield of 0.26 std m3 / kg VS added.

This study represents a few basic steps of municipal solid waste management practiced in the six major cities of Bangladesh, namely, Dhaka, Chittagong, Khulna, Rajshahi, Barisal, and Sylhet. A six-month field study was conducted to identify the solid wastes management steps such as storage at source, separation, on-site storage, collection, transportation, treatment, reuse, recycling, and ultimate disposal. This study addresses the role of the city authority to meet the demand of the city dwellers in solving this emerging socioenvironmental issue and the initiatives taken by some nongovernmental organizations and community based organizations. The problems and constraints of the solid wastes management system are also identified to find a sustainable management concept for the urban areas of Bangladesh.

Municipal solid waste is a big problem in China. Separating and collecting recyclables from municipal solid wastes is a key approach for resolving waste problems and promoting circular economy. The current collection and recycling of recyclables from municipal solid waste is reviewed for better perspective. The material and value stream are summarized for understanding the potential direction of waste and recyclables. The stakeholder for recyclables collection and recycling is identified and their roles are analyzed. Situation of recycling enterprises is introduced. Finally, some comments for promoting recycling industry development are made for reference.

In developing countries, little information is available about solid-waste characteristics, determinants for adoption and performance-evaluation of municipal-waste management systems in Municipals. This study aimed: to characterize the municipal solid-wastes, collection, dumping and evaluate the efficiency and reliability of Municipal solid-waste management system. A total of 200 households were randomly sampled and interviewed. Data was analysed using Binary-Logistic Regression model to determine factors influencing collection and dumping of solid wastes. Results showed that biodegradable/organic wastes comprise a major fraction of solid-wastes produced. Factors that influenced solid-waste collection and dumping included: household-age, unavailability of solid-waste containers, inadequate collection/dumping space and weak legal-enforcement against poor-dumping. The waste system is constrained by inadequate transport facilities, inadequate space for temporal dumping; and lack of legal enforcement in matters of solid-waste poor handling. These have made the systems ineffective and unreliable. This study recommends involvement of all stakeholders in innovative approaches to uphold sustainable municipal sanity.

This report focuses on the potential for using waste carpets as part of cover and liner systems at municipal solid waste landfills. Five different carpet materials were tested for their characteristics before and after incorporation with solid wastes in simulated landfill bioreactors. Selected analyses are presented on heavy metals and volatile organic compounds from TCLP extracts, and on leachate and gas samples during operation with and without leachate recycle. Biological clogging tests indicated no alteration in carpet integrity o2r significant reduction in permeability. Solid waste stabilization, indicated by gas and leachate parameters, proceeded without adverse impact from the codisposed carpets. Volatile organic compounds and heavy metals were present in trace amounts and below regulatory limits. These results supported post-consumer use of carpets as filter and separation layers for municipal solid waste landfill cover and liner systems.

Over the past decade, generation of municipal solid wastes (MSW) in Malaysia has increased more than 91%. However, MSW management in Malaysia can be considered relatively poor and disorganised. The most preferred of MSW disposal method in Malaysia is through landfilling due to several factors. This method is not sustainable and brings a lot of problems. This paper reviews the characteristics of Malaysian MSW, reports the current practices of MSW management, and provides some suggestions to improve MSW management system in Malaysia.

Refuse Derived Fuel

In this paper production of energy efficient Refuse Derived Fuel (RDF) from municipal solid waste rejects was carried out during August 2012 – April 2013 in Coimbatore City India. Municipal Solid wastes rejects (paper, plastics with exception of polyvinyl chloride, textiles) were collected from waste dump yard of Coimbatore City. Sawdust, coir dust, water hyacinth and rice husk were mixed with the collected wastes at a fixed amount of 20 percent. After grinding, cassava starch was used as a binder to produce RDF briquettes with the help of uniaxial piston briquettes making machine. Physical, chemical and thermal characteristics of the RDF were studied to assess their potential use as energy efficient material. The analyses were divided into three categories namely, physical, proximate and ultimate analyses. Results indicated that, under physical and proximate analyses; impact resistance index (IRI) for all the RDF samples were 200, density were less than 1 kg cm-3, moisture were less than 10 % wt, ash content varied from 2.8 to 9.2 % wt, whilst volatile mater had mean value of 83.1 % wt and fixed carbon which is by subtraction ranged from 1.4 to 9.2 % wt. With respect to Ultimate analysis, Oxygen, carbon, hydrogen varied from 27.01 to 39.78 % wt, 44.8 to59.7 % wt, 5.9 to 8.1 % wt respectively. On the other hand nitrogen, sulfur and chlorine ranged from 0.18 to 0.87 % wt, 0.27 to 0.71 % wt and 0.339 to0.521 % wt respectively. Calorific values (high heating values) ranged from 5085 to 6474.9 kcal kg-1. The results were compared with Energy research Centre for the Netherland database and noted that with exception to moisture, fixed carbon and hydrogen other parameters had a significant lower or higher differences. From the study, RDF from municipal solid wastes rejects along with the additives produced high energy efficient materials.
