Inefficient or poorly planned waste management systems are a burden to society and economy. For example, excessively long waste transportation routes can have a negative impact on a large share of the population. This is exacerbated by the rapid urbanization happening worldwide and in developing countries. Sustainability issues should be accounted for at every stage of decision making, from strategic to daily operations. In this paper, we propose a multiobjective optimization model to design a cost-effective waste management supply chain, while considering sustainability issues such as land-use and public health impacts. The model is applied to a case study in Pathum Thani (Thailand) to provide managerial insights.

<p>In pursuing significant infrastructural upgrades to solid waste management systems, how do decision-makers balance social safeguarding with wider system improvements? What are the implications for justice, if the people most affected by the development have been providing unrecognised labour within the waste management system? Adopting an intentionally political lens, this thesis presents an analysis of power and justice within the case study of Tibar’s dumpsite-to-landfill upgrade, in Timor-Leste.   This research was conducted at a critical time while the upgrade was developing. Through a political ecology framework, supported by environmental justice, it emerges that there is a disconnect between stakeholders’ and decision-makers’ intentions versus their ability to act on these intentions. Several systemic barriers exist in waste-pickers’ justice being met. In some instances, these barriers constitute such injustices. This thesis further evidences the claim that the impacts of the growing global waste problem are not evenly distributed throughout society.  Tibar dumpsite is established as a political space where the intersection of waste and labour is dynamic and changing, brought to light by the proposed dumpsite-to-landfill upgrade.</p>

Abstract The current needs of sustainable urban development are rising. As the transport sector expands, emissions continue to rise. Due to their negative impact on human health and the environment, air quality requirements are becoming more and more stringent. At the same time, the amount of waste is increasing. Europe Union policies attempt to relieve the pressure that these two stressors place on urban systems as they themselves expand. Today different solutions are available to decrease greenhouse gas emissions, increase air quality and improve waste management systems. Among them, waste-to-biomethane for use in urban systems deserves more attention. The paper focuses on application of the concept of waste-to-biomethane and the case study of Valmiera is evaluated. The results show that the application of the waste-to-biomethane strategy can contribute to a complete substitution of diesel fuel in urban buses and gives savings of around 1,000 tCO2/year. The price of the biomethane was found to be the most sensitive input factor. It is suggested that it should not exceed 0.40 EUR/Nm3 for a fuel conversion project of a fleet of 10 vehicles. Such a price can be ensured, if dry fermentation technology is chosen for biogas production. However, from the sustainability perspective, wet fermentation is more preferable due to the introduction of a source-separated organic waste management system in the region and higher gas yields. Introduction of this alternative requires additional funds which is a question of policy-level decisions.
