“…Coal-gasification was used since the early 1800s to produce town gas and the first four-stroke engine ran on produced gas in 1876 (Wheeler and De Rome 2002). In the 1850s, most of the city of London was illuminated by ''town gas'' produced from the gasification of coal (Cherubini et al 2008a). Pyrolysis-gasification is a hybrid thermo-chemical conversion process (combination of pyrolysis and gasification process) (NSCA and NSFCAAEP 2002) where solid materials are converted to the gaseous products.…”

Waste-to-energy technologies are considered as one of the key waste treatment technologies due to their energy and heat recovery efficiencies from the waste. A number of research studies were accomplished to understand the potential environmental burdens from emerging waste treatment technologies such as pyrolysis-gasification (PG). The aim of this study was to examine the PG of municipal solid waste (MSW) treatment process through a life cycle assessment (LCA) method. The study also includes a comparative LCA model of PG and incineration to identify the potential environmental burdens from the existing (incineration) and emerging (PG) waste treatment technologies. This study focused on ten environmental impact categories under two different scenarios, namely: (a) LCA model of PG and (b) comparative LCA model of PG and incineration. The scenario (a) showed that PG had significant environmental burdens in the aquatic eco-toxicity and the global warming potential impact categories. The comparative scenario (b) of PG and incineration of MSW showed that PG had comparatively lower potential environmental burdens in acidification, eutrophication, and aquatic eco-toxicity. Both LCA models showed that the environmental burdens were mainly caused by the volume of the thermal gas (emissions) produced from these two technologies and the final residue to disposal. Therefore, the results indicate that the efficiency and environmental burdens of the emerging technologies are dependent on the emissions and the production of final residue to the landfill.

“…Some researchers have focused on optimizing the transportation component of the waste management process [22], and some have provided models to help reduce costs and better organize this process [23]. It has been identified that in some cases the costs and energy consumption of transportation are higher than those involved in landfilling, and it has been proven that these collection and transportation costs are the result of poor collection schedule management and infrastructure [24,25].…”

“…The possibility of an integrated solid waste management was also identified, with the purpose of developing alternative strategies for cost, energy, and emission reduction by proposing "collection combinations" formed by collecting different type of waste from the same location or a nearby location to fill the collecting truck's capacity and decrease fuel costs [22]. This approach is not applicable, however, when considering the e-waste sector.…”

Waste Management System for Batteries

Abstract:We live in a technology driven era where each day new gadgets improve the way we live our lives. Many resources are being spent on building these devices that often turn obsolete overnight. Taking into account that these electronics have a long-term impact on the environment, a waste management system must be embedded in the electronic product lifecycle. In this paper, we propose a monitoring system for recycling batteries from electronic equipment and devices. This solution covers specific waste management issues to manage and reduce battery waste and to recover valuable materials and components. A solution for the continuous monitoring of each battery waste container is also proposed. The solution involves the storage of all information regarding the recycling process, such as pickup date and time, collector's name, quantity, and location. The research is also extended for smartphone usage. This is an important feature for collectors who need to access data in real time from any location. The mobile application directly reads the weight of battery waste, automatically saves the date and time, and stores the location along with any other useful information.

“…Furthermore, in the best MSW management practice, a considerable percentage of the energy consumed during the manufacturing process of the products (Cherubini et al, 2008) may be retrieved and exploited. The energy output of such installations is considered as a Renewable Energy Source (RES) and contributes to the conservation of natural resources, reduces the needs for new conventional power stations and provides security of energy supply (Cheng and Hu, 2010), while a new market is being created amid an international economic crisis.…”

“…Furthermore, the final amount of wastes delivered to landfills is minimized and the corresponding pollution related to all stages of treatment is significantly reduced (Dolgen et al, 2005; Haley, 1990). In this context, the selection of the appropriate strategy for energy recovery by the utilization of MSW depends mostly on the quantity and composition of wastes, the moisture content, the current legislation, geopolitical and climate conditions, the ease of MSW transportation, the exploitation of the products downstream the processes, the initial and operational cost of the plants, the energy balance of each country and the mass and energy balance of the methods adopted (Cherubini et al, 2008;Consogni et al, 2005). …”

Municipal Solid Waste (MSW) management is the field of science which explores and evolves strategies minimizing the final amount of wastes delivered to landfills and reducing the corresponding pollution related to all stages of treatment and collection. In the best practices of MSW the inherent energy of wastes is being recovered. In this study, the most appropriate energy recovery methods utilizing MSW for Greece (i.e. Sorting plant at landfill site with biogas recovery and RDF production, Incineration of MSW with small pre-treatment and Controlled landfill site with biogas recovery) are investigated based on the composition of wastes, the compatibility of the methods with the EU legislation, their technical availability, energy recovery capacity and contribution to the national energy balance, as well as economic issues, the maturity of the technologies involved and the land occupation requirements. A detailed multi-criteria analysis is applied considering the expected MSW production of Greece until 2020 along with different scenarios of waste utilization. Based on the results obtained, as well as on the elaboration of a sensitivity analysis, the "Controlled landfill" method is designated as the most prevalent energy recovery method for Greece, although under specific prioritization of the main parameters involved, the "Incineration" may be equally appropriate as well. KEYWORDS: energy recovery from MSW, Waste-to-Energy plants, incineration of MSW, sorting plant at landfill site, controlled landfill sites. INTRODUCTIONThe increment of Municipal Solid Wastes (MSW) production worldwide in association with the continuously growing concentration of chemical components in the wastes (Mahar et al., 2009) and the storage problems involved, have indicated the need for the implementation of more effective MSW treatment strategies (Sakkas et al., 2005;Konstantinidis et al., 2000). Furthermore, in the best MSW management practice, a considerable percentage of the energy consumed during the manufacturing process of the products (Cherubini et al., 2008) may be retrieved and exploited. The energy output of such installations is considered as a Renewable Energy Source (RES) and contributes to the conservation of natural resources, reduces the needs for new conventional power stations and provides security of energy supply (Cheng and Hu, 2010), while a new market is being created amid an international economic crisis. Furthermore, the final amount of wastes delivered to landfills is minimized and the corresponding pollution related to all stages of treatment is significantly reduced (Dolgen et al., 2005; Haley, 1990). In this context, the selection of the appropriate strategy for energy recovery by the utilization of MSW depends mostly on the quantity and composition of wastes, the moisture content, the current legislation, geopolitical and climate conditions, the ease of MSW transportation, the exploitation of the products downstream the processes, the initial and operational cost of the plants, the energy balance of...
