“…Different assessment tools and methods are developed to address the potential strength, weakness, socio-economic, and environmental benefit from certain waste treatment technologies. As a part of assessment methods, different models (Morrissey and Browne 2004) particularly computerized waste management decision support tools (DST) including multi-criteria optimization (MCO) or multiple criteria analysis (MCA) tools and cost-benefit analysis were started at the end of 1960s (Björklund 2000).…”

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.

“…Plenty of different optimization models share common elements, such as cost-benefit analysis and present value evaluation [26]. The transportation costs are related to certain aspects such as the distance that needs to be traveled, the type and amount of waste that requires transportation, the number of drivers hired to do the job and their pay scales, the collection frequency, the type of vehicles used for collection, and the routing of the vehicles [13].…”

“…This approach is not applicable, however, when considering the e-waste sector. Another approach considered linking the concepts of integrated waste management with those of life cycle analysis in order to achieve environmental benefits, economic optimization, and social acceptability [26,31].…”

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.

“…Due to the complexity of MSWMS, computer models should be built as supporting tools to explain, control or predict the behavior of these systems, as well as to plan and assess waste management [18].Over the past decades, various evaluation techniques have been used to analyze MSWMS. These techniques include numerical solving methods, life cycle assessment (LCA), life cycle inventory (LCI), material flow analysis (MFA), input-output (IO) tables, and several optimization approaches, such as linear programming (LP), mixed integer programming (MIP), and dynamic programming (DP) [19][20][21][22][23].The first MSW models, from the period between the 1960s to the 1970s, were optimization models and mainly dealt with specific aspects of waste management, that included the routing of waste vehicle collection and the location of waste transfer stations [24]. Such models were limited to analyzing only one time period, one processing option, and a single waste generation source; making them unsuitable for long term planning [22,25].…”

Storing municipal solid waste (MSW) in landfills is the oldest and still the primary waste management strategy in many countries. Russia is the third largest methane (CH 4 ) emitter country after USA and China, representing 5% of total global CH 4 emissions from waste landfilling. Due to high economical growth, the amount of waste generated in Russia has risen sharply over the last ten years. However, waste management in Russia is mainly based on landfilling. In order to design an optimal MSW utilization system considering various aspects related to sustainable MSW management, a linear programming model was introduced for this research. The performance of the proposed MSW utilization system in the target area has been evaluated in light of energy, economic, and environmental (3Es) aspects, such as system net cost, annual energy generated from the waste, and the carbon dioxide (CO 2 ) emissions of the system. St. Petersburg city was considered as the target area for the present analysis. The results show that the introduction of the proposed MSW system with energy recovery from waste along with a high level of material recovery has energy, environmental and economic benefits compared to the conventional treatment system. This paper emphasizes the importance of introducing waste treatment methods as an alternative to landfilling, and to improve recycling activities in Russia.Keywords: sustainable waste management; municipal solid waste; waste-to-energy; system design; optimization; linear programming; Russia; St. Petersburg : net costs of each treatment facility (USD/year) p : unit price of by-product (USD/t or USD/GWh) q : waste material allocated to treatment facility (t/year) fr : fraction of residue production at treatment facility fr LFD : fraction of materials (waste and residues) allocated for landfill disposal fr WTE : fraction of waste allocated for energy production fr WTR OPEN ACCESS
