Transition from linear to circular economy in pavement engineering: A historical review

Journal of Cleaner Production, Journal Year: 2024, Volume and Issue: 449, P. 141809 - 141809

Published: March 16, 2024

Navigating the complex pavement system to circular economy is a multi-dimensional and time-consuming endeavour. Obstructed by lock-in mechanisms of prevailing "take-make-dispose" linear mode, current studies in infrastructure often focus only on one certain type practice, featured fragmentation from perspective. This study presents first systematic literature review historical development trend concept sector based collected 59 2006 2022. also identifies soft (regulatory, social/environmental) hard (technical, market/economic) drivers of- barriers paradigm shift, aiming coordinate existing fragmented findings facilitate future systemic implementation economy. The synthesis results indicates that underdeveloped technical guidance legal are inhibiting shift Furthermore, authors argue importance transparent standardized data along whole supply chain should be highlighted. Ultimately, this paper suggests welcoming environment set road authorities crucial for innovation entrepreneurship, as well constructing where stakeholders can confidently take responsibility initiative.

Mapping the evolution of manganese flows and stocks in China from 2000 to 2021

Resources Environment and Sustainability, Journal Year: 2024, Volume and Issue: 16, P. 100152 - 100152

Published: March 1, 2024

Manganese is a strategic metal that has been widely applied in the steelmaking industry and emerging energy batteries industry. China largest manganese importer consumer, but critical features of its metabolisms, including supply demand, trade, waste management, remain unclear. By applying dynamic material flow analysis (DMFA) method, this research investigates evolution China's anthropogenic flows stocks during period 2000 to 2021. We found demand for had increased almost tenfold from 2021, mainly used steelmaking, while surging gradually increased. However, highly relied on importing concentrates due limited resources. The cumulative in-use also by reached approximately 168 million tons (Mt). In addition, end-of-life (EoL) final products 12 Mt few them were recycled, implying huge recycling potential. These findings provide valuable insights prepare more appropriate resource management policies, such as improving domestic mining technologies, enhancing recycling, diversifying resources, so overall efficiency can be improved.

A novel method of accounting for plastic packaging waste

Waste Management, Journal Year: 2025, Volume and Issue: 196, P. 42 - 50

Published: Feb. 19, 2025

The European Union (EU) has set itself the goal of becoming a resource-efficient circular economy. It therefore begun tackling its increasing amounts packaging waste using both regulations and strategies, with member countries aiming to increase their recycling rates for plastic 55% by 2030. However, EU states have different methods collecting data on rates, which makes it difficult compare performance in reaching that target. This article introduces method compile industry-specific accounting packaging, Finnish economy as an example. combines from extended producer responsibility scheme standard economic statistics, thus enabling calculation transparent estimates total amount placed market. also provides sector-specific management strategies are aimed at achieving higher material rates. is compared approach based analysis, demonstrating results market more reliable. available linked generalisations composition studies own uncertainties.

Published: April 23, 2024

Effective waste separation at the source is vital for sustainable management globally. However, motivating people to participate in can be challenging, especially developing countries' megacities, where rapid urbanization and surging solid trends are prevalent. A survey conducted Bangkok, Thailand, provides valuable insights into factors that encourage among individuals from diverse backgrounds. The study involved 456 respondents, an effect size of 0.35, a 95% confidence level, 5% margin error. sample groups were divided four modules based on their lifestyles analysed intention behaviour using extended theory planned structural equation model. results showed attitude critical fundamental factor influencing intention, while trust recycling system most significant behaviour. Furthermore, each module differ, highlighting need specific strategies promote with megacities.

Biotechnological model for ubiquitous mixed petroleum- and bio-based plastics degradation and upcycling into bacterial nanocellulose

Journal of Cleaner Production, Journal Year: 2024, Volume and Issue: 443, P. 141025 - 141025

Published: Feb. 8, 2024

Ubiquitous post-consumer plastic waste is often physically mixed combining recalcitrant petroleum-based plastics with bioplastics, forming (petro-bio)plastic streams. Finding appropriate end-of-life (EoL) strategies for highly pertinent in achieving environmental protection, sustainability value chain industries including recyclers and government policy makers worldwide. The presence of bioplastic polyethylene terephthalate (PET) or other streams poses a substantial drawback to mechanical recycling strongly impedes the development sustainable EoL routes. Here, we present model system management waste, demonstrating biotechnological route through synergy-promoted enzymatic degradation PET–representing petrochemical polyester plastic–mixed thermoplastic starch (TPS)–as bioplastic.
