Managing growing waste tires requires strategies that address disposal while contributing to energy generation and climate mitigation. This study employs auto regressive integrated moving average modeling to forecast end-of-life tires generation based on vehicle ownership trends in Hong Kong. A life cycle assessment using the ReCiPe2016 method and a genetic algorithm optimization is applied to assess and optimize the environmental and energy impacts of combined heat and power, gasification, and pyrolysis technologies under two scenarios: the baseline scenario, where 50 % of end-of-life tires are utilized for energy production reflecting current practices, and the enhanced scenario, which increases this to 65 % by including end-of-life tires that would otherwise be improperly disposed of. Although the baseline scenario produced slightly more energy, the optimized use of end-of-life tires in the enhanced scenario prioritized substantial climate benefits through strengthened greenhouse gas mitigation. In the enhanced scenario, greenhouse gas emissions were reduced by approximately 357,825 tons of CO₂-eq annually by 2025, leading to a cumulative reduction exceeding 3 million tons by 2030. Additionally, the enhanced scenario demonstrated improvements in reducing air pollutants such as SO<sub>2</sub> and NO<sub>x</sub>, further contributing to better air quality. The findings highlight the potential of integrating end-of-life tires-to-energy technologies for sustainable end-of-life tires management, providing a framework for policymakers and stakeholders to develop effective strategies that contribute to environmental sustainability and public health.

As a viable alternative, microalgae-based biodegradable plastics offer an environmentally sustainable solution owing to the rapid growth of microalgae and their ability to absorb CO<sub>2</sub>. However, the high price of bioplastics hinders their widespread adoption as a replacement for conventional plastics. In this study, an integrated process (Case 1) for coproducing lactic acid (LA, a monomer of polylactic acid), polyurethane, and azelaic acid (AA), by fully utilizing the major components of microalgae (carbohydrates, triglycerides, and free fatty acids (FFAs)) is proposed. This method significantly improves the economics of bioplastic production. Apart from AA production from FFAs, which is a common process to produce LA and polyurethane, two additional cases are also presented to investigate the environmental and economic impact of FFA utilization: Case 2 consumed FFAs as a heat source and Case 3 externally disposed of FFAs. Comprehensive analyses, including techno-economic analysis and life cycle assessment, were conducted to identify the economic and environmental benefits of the three cases. Case 1 is the most economically advantageous option, with the lowest minimum selling price (MSP) of $1017/ton-LA due to additional revenue from the sales of AA, which is a valuable product. Despite its economic benefit, Case 1 is not environmentally favorable (6.6 kg CO<sub>2</sub> eq./kg-LA). In contrast, Case 2 has the lowest global warming potential (2.3 kg CO<sub>2</sub> eq./kg-LA), equivalent to an annual reduction of 135,865 metric tons of CO<sub>2</sub> emissions in comparison to the conventional LA production process (4.8 kg CO<sub>2</sub> eq./kg-LA); conversely, it has the highest MSP of $1605/ton-LA. This denotes that the proposed process can reduce annual 135,865 tons of CO<sub>2</sub> with competitive price compared to the conventional LA ($1100-1940/ton).

Two field experiments are conducted to reveal the dynamics and mechanisms of children's influence on their parents' environmentally friendly behaviour. The result of Study I (Number of experimental group = 320, Number of control group = 314) suggests that trans-education within the family, initiated by children who have received education on green and low-carbon, fosters enhanced green consumption behaviour among their parents. Expanding upon this insight, Study II (Number of experimental group = 1588) elucidates that the transformation in parents' behaviour is not immediate but rather follows a “push” mechanism. Specifically, trans-education stimulates moral elevation in parents, eliciting positive moral motion and a heightened proclivity towards green and low-carbon actions. Moreover, trans-education not only directly inspires parents to cultivate more personal norms related to green and low-carbon, but also reinforces parents' personal norms by further bolstering their moral elevation, ultimately translating into concrete green and low-carbon actions. Notably, the attribution of parental responsibility moderates the impact of trans-education on green consumption behaviour. Parents who hold a high sense of parental responsibility not only assimilate cross-generational education more effectively but also excel at transforming these notions into tangible green consumption behaviour.</div></div>","PeriodicalId":48619,"journal":{"name":"Sustainable Production and Consumption","volume":"55 ","pages":"Pages 257-267"},"PeriodicalIF":10.9,"publicationDate":"2025-02-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143520732","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Life Cycle Sustainability Assessment (LCSA) can aid the technology development by evaluating the sustainability implications between increased treatment and resource recovery and reuse. This study applies LCSA to four case studies involving innovative brine treatment and recovery systems: a demineralised water plant, a coal mine, textile plant and a silica plant. The results demonstrate potentially significant environmental and economic benefits of the Zero Brine systems compared to the reference systems. Climate change is lower for the Zero Brine systems in 3 of the 4 cases, reducing from: 3.0 to 2.5 CO<sub>2</sub> eq/m<sup>3</sup> for the demineralised water plant, 18.6 to 10.7 CO<sub>2</sub> eq/m<sup>3</sup> for the coal mine and 0.29 to −4.7 CO<sub>2</sub> eq/m<sup>3</sup> for the silica plant (the negative value representing a credit due to recovered materials replacing virgin ones). This represents reductions in climate change of between 13 % to 1690 %. Other impacts of the Zero Brine systems were lower for the coal mine and silica plant, but higher for the DWP and textile plant (apart from resource depletion). Life Cycle Costing shows an increase of 45 % and 352 % in costs for the silica and demineralised water plant plants respectively, but a decrease of 14 % and 93 % in costs for the coal mine and textile plant respectively. The main social benefit is shown to be reductions in water use, which was reduced by up to 90 % in the silica plant case study. Other social indicators indicate minimal change, as many consumables in both systems are derived from European production. The study demonstrates that the benefits of Zero Brine systems depend on the recoverable sustainability “value” of the brine's constituents and whether they offset the increased consumption of energy and chemicals. The utilised LCSA approach of minimising the number of indicators and avoiding aggregation, helps to maintain transparency and interpretability, whilst streamlining the process and aiding communication and visibility.

This study investigates the economic impact of double Fairtrade and Organic certifications on smallholder coffee farmers in Ethiopia, a major coffee-producing country where these certifications are widely adopted. The analysis is based on survey data collected from certified and noncertified smallholder coffee producers using a multistage random sampling approach. To ensure the robustness of the findings, the study employs Propensity Score Matching (PSM), Endogenous Treatment Regression (ETR), and Ordinary Least Squares (OLS) methods. The results across all estimation techniques consistently reveal that certified farmers experience significant increases in coffee yield, price, and dividends from coffee sales, despite an associated rise in total production costs. By incorporating cooperative performance as a control variable to account for potential confounding effects of cooperative characteristics, the estimated treatment effects were slightly moderated; however, the positive impact of VSS certification remained statistically significant. These findings suggest that VSS certifications contribute to improving the livelihoods of smallholder coffee farmers, although challenges persist in optimizing the cost-effectiveness of compliance.

The review synthesizes findings from various LCA studies, revealing substantial variability in life cycle efficiency and environmental impacts across different DACCS systems. Solid sorbent technologies demonstrate average net greenhouse gas reductions of 640 kg CO₂-eq/t CO₂, while liquid sorbent systems achieve reductions of about 560 kg CO₂-eq/t CO₂, with system carbon efficiencies ranging between 56 % and 64 %, influenced by operational conditions and regional factors.

For gigaton-scale facilities, significant environmental trade-offs emerge, including substantial particulate matter emissions (170–180 kt annually) and varying impacts on marine eutrophication (up to 90 % higher for amine-based systems compared to hydroxide-based alternatives). Low-temperature DAC systems exhibit higher human toxicity and ecotoxicity impacts due to increased electricity demands, while metal resource depletion varies significantly based on system design and energy sources.
