The burgeon concept of Circular Economy (CE) has fundamental issues hindering clarity and comprehensive assessments. This paper uses established ontological criteria to review and improve the CE definition and (assessment) frameworks. The review reveals that mainstream CE definitions and assessments are fuzzy, shift problems, oversimplified and not...

Lithium-ion batteries have become a crucial part of the energy supply chain for transportation (in electric vehicles) and renewable energy storage systems. Recycling is considered one of the most effective ways for recovering the materials for spent LIB streams and circulating the material in the critical supply chain. However, few review articles...

Introduction - The aim of this paper is to explore data quality as an antecedent of commercially viable business models within the circular economy. Australian state governments are developing policies to enable a circular economy. However, in the building industry most data systems rely on self-reporting, which has compromised the accuracy, object...
Technical Report
Full-text available
This report examines the challenges and opportunities arising from transitioning to a circular economy in Australia and New Zealand. The fact is that as populations rise, material use increases. Historically, we have seen a trend globally whereby material use per person increases as incomes grow. In developed economies, waste has largely been ‘out...

Circularity supports the move from linear to circular systems where more efficient, zero waste systems are created by closing material inputs and loops. The design, maintenance, manufacturing and use ensure virgin materials are no longer needed for day to day living. For the built environment sector, building materials and its use underpins the tra...
