Waste Management & Research The Journal for a Sustainable Circular Economy · 2024

The management of end-of-life vehicles (ELVs) has become a significant environmental and economic challenge due to the substantial volumes of hazardous waste generated. This article analyses sustainable practices in ELV management across Europe, with a focus on contributions to the circular economy. The systematic literature review, conducted for articles published in the period 2016-2024, identifies five topics: (1) policy and regulatory frameworks evaluations and suggestions; (2) economic and environmental benefits through optimization modelling; (3) trends and performances analysis; (4) advanced treatment technologies and their impact and (5) economic and environmental impacts assessments. The findings highlight the importance of state-of-the-art recycling processes and coordinated stakeholder efforts in improving ELV management outcomes. In addition, the correlation between ELVs recycling and gross domestic product (GDP) was analysed. Data analysis for 27 European countries in the period 2016-2021 shows a moderate correlation. Specifically, countries with stronger economies tend to produce more ELVs, distinguishing two clusters when GDP is 35,000 € per capita. By adopting best practices and innovative approaches, European countries can enhance their ELV management systems, support a more circular economy and sustainable development. This work highlights the possible correlation between GDP per capita and ELV recycling rates across the European Union, the identification of economic clusters, and the critical role that advanced recycling technologies play in improving sustainability.

Greenhouse gas (GHG) emissions from building activities are one of the most prominent contributors to the problem of global warming. Life-cycle assessment (LCA) is a widely used tool to investigate GHG emissions from buildings. However, there appears to be a lack of LCA studies on buildings in tropical climates, and especially in Thailand. This study aims to improve the understanding of GHG emissions from standard Thai residential buildings. LCA was conducted on five typical house designs in Thailand in order to determine potential mitigation strategies for future design of these houses. The amount of GHG emissions over the entire life-cycle of these detached houses was estimated, and the results were analysed with different viewpoints. The results indicate that emissions from the operational energies of detached houses in Thailand have the highest share of GHG emissions. Significant emissions also came from construction materials. Improvements to the building envelope and air-conditioner usage have high GHG mitigation potential in the operational stage of the buildings, while replacing cementitious and metallic materials with low-emissions alternatives can considerably reduce embodied emissions. Policy relevance The built environment has been a major source of GHG, but it also has high climate change-mitigation potential. This study explores mitigation strategies on the material and component levels of the most common building type in Thailand: detached houses. The results indicate the major sources of GHG emissions in the case study buildings, their correlation with building scale and other key design decisions. Potential mitigation solutions in different phases of the building life-cycle are identified.

Nature-Based Solutions · 2024

Nature-based solutions (NbS) are recognized as one of the approaches that can address a range of environmental issues, often with conservation and natural resource management missions. However, the promotion of NbS often lacks a robust understanding of their actual impacts and effectiveness. To support the evaluation and implementation of NbS, there is a need for a comprehensive quantitative assessment framework. The main objectives of the study are to (1) develop an assessment framework that can be used to quantify the performance of NbS interventions and to (2) provide a step-by-step guideline for evaluating NbS. The assessment framework proposed in this study was built upon existing frameworks used in previous studies, designed to address specific gaps. Several aspects and tools were integrated in response to the NbS standard criteria provided by the International Union for Conservation of Nature (IUCN), as a result, this quantitative assessment framework can provide a comprehensive evidence based on environmental, social, and economic aspects. The study introduced one approach, viz., the System of Environmental-Economic Accounting - Ecosystem Accounting (SEEA EA), and three main assessment tools (i.e., Life Cycle Assessment (LCA), Social Life Cycle Assessment (S-LCA), and Cost-Benefit Assessment (CBA)) aimed at facilitating a comprehensive evaluation of NbS. The results provide a conceptual framework that offers a systematic approach for evaluating the performance of NbS, along with methods to address conflicting results among aspects and/or indicators. Ideas and approaches for assessing ecosystem services provided by NbS and primary concerns when conducting NbS assessments are also highlighted. In summary, the conceptual framework proposed in this study can be used to assess NbS performance and determine whether NbS interventions align with the NbS standard criteria provided by IUCN, utilizing the introduced assessment tools.

Solid waste management is a cross-cutting issue that significantly influences multiple aspects of sustainable development globally. The waste sector is a major anthropogenic source of global greenhouse gas (GHG) emissions. Most global GHG assessments of waste management rely on generic data due to limitations in available data. This research used reflective inventory data for municipal solid waste (MSW) treatment systems related to the income levels of countries, resulting in more context-specific and comprehensive assessments of GHG emissions. This study aims to assess life cycle GHG emissions from the global MSW management sector for the years 2023, 2030, and 2050 and then analyses the global and regional waste management goals set by the United Nations Environment Programme (UNEP) and the European Union (EU) to identify hotspots in the MSW management systems and critical factors that influence GHG emissions from the waste sector. The study was conducted in accordance with the standards outlined in ISO 14067:2018. The results show that the average global GHG emissions from 1 tonne of MSW in 2023 based on the existing MSW management practices was approximately 89.7 kg CO 2e . The major contributor was the open dumping of MSW, contributing almost 70 % of GHG emissions. The global MSW management sector emitted a total of 173.2 Mt CO 2e GHG emissions in 2023. If no improvements are made to existing systems, GHG emissions from the waste sector are projected to increase to 203.4 Mt CO 2e by 2030, and to 289.5 Mt CO 2e by 2050. Achieving waste management goals can reduce GHG emissions by approximately 1 % to more than 160 %. The implementation of the circular economy in the waste sector has the potential to achieve net zero emissions from the global MSW management sector by 2030 and 2050. This study provides achievable MSW management targets for the world and highlights key factors to achieve carbon neutrality from the waste sector. Prioritising policies such as upgrading open dumps, standardising household-level waste separation procedures, minimising food waste, establishing national recycling targets, and promoting circular economy through a zero-waste approach could substantially reduce GHG emissions from the waste sector. These findings are important for the adoption of circular economy principles in MSW management systems to effectively support the pursuit of carbon neutrality goals.
