AbstractAbstract
[en] A successful recycling program requires several components: education and promotion, convenient collection service, and most importantly, a market for collected materials. In Washington state, domestic markets currently have, or are building, the capacity to use most of the glass, newsprint, aluminum, tin cans, and corrugated materials that are collected. Unfortunately, markets for mixed waste paper (MWP), a major component of the state's solid waste stream, have been slow to develop and are unable to absorb the tremendous volumes of material generated. The American Paper Stock Institute classifies MWP as low grade paper such as magazines, books, scrap paper, non-corrugated cardboard (boxboard/chipboard), and construction paper. When viewed as part of a curbside collection program MWP consists primarily of catalogs, binder paper, magazines, brochures, junk mail, cereal boxes, and other household packaging items. A comprehensive analysis of Washington State's solid waste stream showed that during 1988, Washington citizens generated approximately 460,000 tons of mixed waste paper. No small amount, this is equivalent to more than 10% of the total solid waste generated in the state, and is expected to increase. Current projections of MWP generation rates indicated that Washington citizens could discard as much as 960,000 tons of MWP by the year 2010 making it one of the single largest components of the state's solid waste stream. This paper reports on the use of MWP as fuel source

AbstractAbstract
[en] Highlights: • A review of public involvement in waste management decision-making was undertaken. • Public involvement seen as necessary to create stronger foundations for decisions. • The mode and level of public involvement explored in different decision contexts. • Public involvement can be negotiated based on the technological and social context. • Early public involvement favoured where issues are contentious or uncertain. - Abstract: The technical expertise that politicians relied on in the past to produce cost-effective and environmentally sound solutions no longer provides sufficient justification to approve waste facilities. Local authorities need to find more effective ways to involve stakeholders and communities in decision-making since public acceptance of municipal waste facilities is integral to delivering effective waste strategies. This paper presents findings from a research project that explored attitudes towards greater levels of public involvement in UK waste management decision-making. The study addressed questions of perception, interests, the decision context, the means of engagement and the necessary resources and capacity for adopting a participatory decision process. Adopting a mixed methods approach, the research produced an empirical framework for negotiating the mode and level of public involvement in waste management decision-making. The framework captures and builds on theories of public involvement and the experiences of practitioners, and offers guidance for integrating analysis and deliberation with public groups in different waste management decision contexts. Principles in the framework operate on the premise that the decision about ‘more’ and ‘better’ forms of public involvement can be negotiated, based on the nature of the waste problem and wider social context of decision-making. The collection of opinions from the wide range of stakeholders involved in the study has produced new insights for the design of public engagement processes that are context-dependent and ‘fit-for-purpose’; these suggest a need for greater inclusivity in the case of contentious technologies and high levels of uncertainty regarding decision outcomes.

AbstractAbstract
[en] Approximately half the energy produced in Union European's municipal waste incineration plants is obtained from fermentescible waste (i.e. biomass waste). To date, incineration is still the main energy conversion channel for renewable municipal waste, for in 2009, biomass energy output stood at 7.7 million toe, which is a 3.3% increase on 2008. Furthermore, this amount could be doubled, assuming a constant level of waste, by investing in modernization and combustion efficiency improvements. (author)

AbstractAbstract
[en] In Malaysia, the greenhouse gases (GHGs) emissions reduction via composting of source-separated organic waste (SOW) in municipal solid waste (MSW) has not been assessed. Assessment of GHG emissions reduction via composting of SOW is important as environmental impacts from waste management are waste-specific and local-specific. The study presents the case study for potential carbon reduction via composting of SOW in University of Malaya (UM). In this study, a series of calculations were used to evaluate the GHG emission of different SOW management scenarios. The calculations based on IPCC calculation methods (AM0025) include GHGs emissions from land filling, fuel consumption in transportation and SOW composting activity. The methods were applied to assess the GHG emissions from five alternative SOW management scenarios in UM. From the baseline scenario (S0), a total of 1,636.18 tCO2e was generated. In conjunction with target of 22 % recycling rate, as shown in S1, 14 % reduction in potential GHG emission can be achieved. The carbon reduction can be further enhanced by increasing the SOW composting capacity. The net GHG emission for S1, S2, S3 and S4 were 1,399.52, 1,161.29, 857.70 and 1,060.48 tCO2e, respectively. In general, waste diversion for composting proved a significant net GHG emission reduction as shown in S3 (47 %), S4 (35 %) and S2 (29 %). Despite the emission due to direct on-site activity, the significant reduction in methane generation at landfill has reduced the net GHG emission. The emission source of each scenario was studied and analysed. (author)

AbstractAbstract
[en] A laboratory investigation was conducted to investigate the filtration behavior of geotextiles to remove suspended solids from municipal wastewater. Four nonwoven geotextiles were used in this preliminary investigation. The study also involved evaluating the suspended solids removal efficiency and regeneration potential of geotextiles for using as filter media. Wastewater samples were collected from the local wastewater treatment plant. Influent and effluent suspended solids concentration, chemical oxygen demand, and effluent flow rates were monitored during the tests. During filtration tests, suspended solids were retained on the upstream face and within the geotextile as wastewater passed through it. Due to the formation of a thin layer of suspended solids or filter cake on the upstream face of the geotextile, the effluent flow rate and suspended solids concentration decreased exponentially with time. When the effluent flow rate reduced below 90%, the filter media was backwashed to restore its filtering efficiency, for reuse. Based on the results of this study, it was concluded that using geotextile columns, it was possible to remove 50 to 70% of suspended solids and decrease in chemical oxygen demand from 70 to 90% from the influent. This technique may be suitable for treating wastewater streams with low inflow and suspended solids concentrations, preferably in the range of 100 to 200 mg/L. The technique may be further evaluated for determining its suitability for treatment of wastewater generated from less populated areas and as a polishing step after secondary treatment. (author)
