“…Several types of material, such as paper, glass, and plastic could be transformed into other usable products. In addition, energy recovery from waste is also proposed, since it was found that waste could be used to generate fuel and energy through a different waste process [17][18][19][20][21][22]. However, some types of waste, particularly hazardous waste, are not easy to reuse and recycle.…”

Abstract:The aim of this study is to explain individuals' engagement in sustainable waste management behaviors (SWMBs) based on the application of protection motivation theory (PMT). SWMBs include waste avoidance, green purchasing, reuse and recycle, and waste disposal behaviors. Considering the amount of solid waste generation per capita per day during the past 10 years, the statistical records from the Bangkok Metropolitan Administration (BMA) illustrate the increasing trend of solid waste generation from 1.18 kg per capita per day in 2005 to 1.28 kg per capita per day 2015. Many scholars have asserted that human beings should alter their behaviors to successfully reduce their environmental impact. Several environmental problems (e.g., air pollution, water pollution, and odors) caused by waste disposal are consequences of human behaviors; therefore, citizens' engagement in SWMBs should be widely promoted. This study applies PMT to explore how individuals' SWMBs are influenced by their perceived threats caused by environmental contamination from waste disposal and their perceived coping capability. The Bangkok metropolitan area was selected as a case study because it has faced serious waste management problems, caused by increasing amounts of solid waste over the last ten years. Questionnaire surveys were administered to 193 public and private office workers residing in the city of Bangkok. Multiple linear regression analyses were performed to justify the effects of individual threat appraisal and coping appraisal on SWMB engagement. The results illustrated that respondents' self-efficacy could explain all types of SWMBs. On the contrary, response efficacy was not a significant predictor of all behaviors. People's perceived severity of adverse consequences caused by pollutants could significantly explain their waste disposal and reuse and recycle behaviors, and the perceived probability of being impacted by pollutants could explain only reuse and recycling behaviors. Thus, PMT may be well suited for explaining low-cost and simple SWMBs that require less effort. To promote people's engagement in each type of SWMB, different communication campaigns should be established.

“…Worldwide, there are different types of technologies for the same thermal treatment processes [19][20][21][22][23][24][25][26]. Source reduction, generation, recovery and disposal [27,28] constitute some of the most important segments of integrated MSW management (IMSWM).…”

Abstract:In the new legislation framework enacted by new member countries of the European Union (EU), the characterization of municipal solid waste (MSW) represents an important instrument for local governments and sanitation operators in setting and achieving targets for waste recycling and recovery. This paper presents the results of a study conducted in accordance with the Romanian methodology for domestic wastes characterization ROMECOM, aiming to provide a proper basis for developing clear and realistic forecasts in current municipal waste management, based on MSW composition and generation rate. The analyzed MSW came both from areas where the waste is collected in mixed and separate ways, in urban and rural areas. The MSW composition by fraction is detailed for dense urban areas, urban areas, rural and touristic areas from Romania. Based on these results, the MSW composition was determined for the eight development regions in Romania, and a generation rate of 0.9·kgMSW inhabitant by selective collection (different efficiencies for urban and rural areas) with subsequent recovery of the separated materials and energy recovery of the residual waste in a large-scale waste to energy (WTE) plant.

“…This fraction is partially biodegradable, so it is not considered as pure biomass. However, MSW refuse usually contains a biodegradable fraction over 50% [13] and therefore, it could be interesting use it as feedstock for bioenergy production [14]- [16]. The studied concept of advanced WtE plant is a facility producing products and/or services from MSW refuse e.g.…”

Recently, the European Parliament has decided to include a specific reference to "Enhanced Landfill Mining" (ELFM) in the Landfill Directive proposing a regulatory framework for ELFM so as to permit the retrieval of secondary raw materials that are present in existing landfill sites. Recent studies are supporting ELFM since they consider that landfill mining would be economically feasible only if combined with energy recovery (i.e., waste-to-energy, WtE) and if a wide range of materials are recovered (i.e., waste-to-materials, WtM). In this study, a combined material (landfill mining) and energy (advanced WtE) recovery is proposed where the excavated waste (MSW refuse) can be directly recycled or pretreated and used in the production of refuse-derived fuel (RDF) for an advanced (gasification-based) WtE plant producing power and heat. Both material and energy recovery are challenging in the circular economy since contributes to a loop-closing objective in human activities. An exhaustive assessment of each particular landfill site must be carried out in order to determine the profitability of the ELFM.
