In the last decades, integral municipal solid waste management (IMSWM) has become one of the most challenging areas for local governmental authorities, which have struggled to lay down sustainable and financially stable policies for the sector. In this paper a model that evaluates the efficiency of IMSWMs through a combination of Data Envelopment Analysis (DEA) and an Artificial Neural Network (ANN) is presented. In a first stage, applying DEA, municipal administrations are classified according to the efficiency of their garbage processing systems. This is done in order to infer what modifications are necessary to make garbage handling more efficient. In a second stage, an ANN is used for predicting the necessary resources needed to make the waste processing system efficient. This methodology is applied on a toy model with 50 towns as well as on a real-world case of 21 cities. The results show the usefulness of the model for the evaluation of relative efficiency and for guiding the improvement of the system.

The need for resilience and an agile waste management system in Saudi Arabia is vital to control safely the rapid growth of its municipal solid waste (MSW) with minimal environment toll. Similarly, the domestic energy production in Saudi Arabia is thriving and putting a tremendous pressure on its huge reserves of fossil oil. Waste to energy (WTE) plants provides a golden opportunity for Saudi Arabia; however, both challenges (MSW mitigation and energy production) are usually looked at in isolation. This paper at first explores the potential of expanding the WTE energy production in the eastern province in Saudi Arabia under two scenarios (complete mass burn with and without recycling). Secondly, this study analyzes the effect of 3Rs (reduce, reuse, recycle) practices implementation in a residential camp (11,000 population) to influence the behavior of the camp’s citizens to reduce their average waste (kg/capita). The results of the 3R-WTE framework show a potential may reach 254 Megawatt (MW) of electricity by year 2030. The 3R system implementation in the camp reduced MSW production from 5,625 tons to 3000 tons of household waste every year, which is considered lower than what the surrounding communities to be produced in the same area.

Avoided Emissions

More light is being shed continually on the environmental impacts of municipal solid waste due to the increasing amounts of waste generated and the related greenhouse gas emissions. Emissions from MSW account for 20% of Canadian greenhouse gas (GHG) emissions and accordingly, waste legislation in Ontario demands high waste recovery and a moving towards a circular economy. This study evaluates the current municipal solid waste management in the City of Guelph and assesses possible alternative scenarios based on the associated GHG emissions. Waste Reduction Model (WARM) that was developed by the US-EPA has been used to quantify the GHG emissions produced over the entire life cycle of the MSW management scenario. Sensitivity analysis was also conducted to investigate the influence of some scenarios on the overall GHG emissions. It has been found that one ton of landfilled waste generates approximately 0.39 ton of carbon dioxide equivalent (CO2Eq). It was also found that the current solid waste scenario has a saving of 36086 million ton of CO2Eq (MCO2Eq). However, the results showed that the scenario with enhanced waste-to-energy, reduction at source and recycling has resulted in a high avoided emissions (0.74 kg CO2Eq/kg MSW). The anaerobic Digestion scenario caused the lowest avoided emissions of 0.39 kg CO2Eq/kg MSW. The net avoided emissions for reduction at source scenario were found to be the same as that found by the current scenario (0.4 kg CO2Eq/kg MSW). The sensitivity analysis of both reduction at source and recycling rates show a linear inverse proportional relationship with total GHG emissions reduction.

The article analyzes the features of municipal solid waste management in Tokyo. Special attention is paid to the analysis of trends in the volume of waste in the city of Tokyo over the past decades, as well as the reasons for the constant decline in these volumes. The article deals with the waste management activities of the Clean Authority of Tokyo, discusses the features of treatment of various types of waste, as well as the arrangement of the Tokyo city waste landfill. It was noted that the capital of Japan succeeded in creating an effective system for the disposal and recycling of municipal solid waste that can ensure the environmental safety of the city, as well as integrate waste into the country’s fuel and energy complex. An important feature of Japanese waste management companies is the desire not only to comply with official environmental standards, but also to adhere to their own standards, even more stringent. Based on an analysis of Japanese experience, the authors put forward proposals for optimizing the sphere of waste management in Russia. In particular, attention is drawn to the need to prevent an environmental catastrophe caused by a careless attitude to waste, improve the quality of life of citizens, prevent social unrest associated with environmental pollution, and also involve waste in the generation of electricity and heat. The authors note that as part of the “trash” reform, it is necessary to increase the environmental awareness of citizens, provide citizens with relevant and complete information about the industry, and create stricter environmental standards for waste to energy plants and other enterprises involved in waste management.
