The presence of chemicals causing significant adverse human health and environmental effects during end-of-life (EoL) stages is a challenge for implementing sustainable management efforts and transitioning towards a safer circular life cycle. Conducting chemical risk evaluation and exposure assessment of potential EoL scenarios can help understand the chemical EoL management chain for its safer utilization in a circular life-cycle environment. However, the first step is to track the chemical flows, estimate releases, and potential exposure pathways. Hence, this work proposes an EoL data engineering approach to perform chemical flow analysis and screening to support risk evaluation and exposure assessment for designing a safer circular life cycle of chemicals. This work uses publicly-available data to identify potential post-recycling scenarios (e.g., industrial processing/use operations), estimate inter-industry chemical transfers, and exposure pathways to chemicals of interest. A case study demonstration shows how the data engineering framework identifies, estimates, and tracks chemical flow transfers from EoL stage facilities (e.g., recycling and recovery) to upstream chemical life cycle stage facilities (e.g., manufacturing). Also, the proposed framework considers current regulatory constraints on closing the recycling loop operations and provides a range of values for the flow allocated to post-recycling uses associated with occupational exposure and fugitive air releases from EoL operations.

Abstract The current dominating production and consumption model is based on the linear economy (LE) model, within which raw materials are extracted-processed-consumed-discarded. A circular economy (CE) constitutes a regenerative systemic approach to economic development which views waste as a valuable resource to be reprocessed back into the economy. In order to understand the circular strategy for a systemic change from an LE to a CE as a means of resolving the issue of plastic waste, this research aims to map current circular strategy trends across the system perspective contained in the literature relating to plastic CE literature. The novelty of the research lies in the mapping and review of the distribution of comprehensive circular strategies within the 9R framework across the entire system perspective (e.g. micro-meso-macro) down to its sub-levels in the literature on a plastic CE. The bibliographic mapping and systematic literature review iindicateed that the majority of the research focused on recycle (R8), followed by refuse (R0), reuse (R3), and reduce (R2). Certain circular strategies are more appropriate to handling certain plastic materials, despite CE's favoring of prevention and recycling over incineration. Recover (R9) is often used to process mixed and contaminated plastic. Recycling (R8) is the most popular circular strategy and the most applicable to plastic material with three recycle trends, namely; mechanical recycling, chemical recycling and DRAM (Distributed-Recycling-and-Additive-Manufacturing). Prolonging the product life through refurbishing (R5) is not applicable to plastic due to its material limitations. Reduce (R2) popularity as circular strategy reflects the preference to reduce consumption, either by launching campaigns to prevent waste or increasing production efficiency. Research on Rethink (R1) has largely focused on rethinking product design, consumer and organization behavior and perceptions of CE. Refuse (R0) strategy is an adoption of bio-based plastics which have a similar function to fossil-based plastics.

The notion of the circular economy (CE) has recently been put forth as a strategy to mitigate climate change. It has gained attention in policy circles and in the engineering and natural science literature. In contrast to the linear model of production, use and disposal, the point of departure for the CE is the creation and sustention of a regenerative system with the goal of minimising resource inputs and emissions. However, although the emerging literature has discussed the ongoing transition process towards the CE, mainly from an ecological perspective, the underlying mechanisms of industrial change including structural tensions have not been discussed. Responding to this gap in the literature, the aim of this paper is to discuss CE as an evolutionary process and to propose a conceptual framework that builds on a development block approach.

Understanding which drivers and barriers exist in the development of a circular economy (CE) is a relevant and timely endeavour. The aim of this paper is to contribute to this debate by analysing evidence regarding the different factors helping and hampering the development of a CE. Specifically, this paper focuses on the eco-innovation (EI) pathway towards a CE, and tries to coordinate available but fragmented findings regarding how “transformative innovation” can foster this transition while removing obstacles to sustainability. Drawing upon a new corpus of both academic and non-academic literature, this work offers a framework for analysis, as well as an evidence-based survey of the challenges, for a green structural change of the economy. We argue that the combination of the innovation systems' view with the more recent “transformation turn” in innovation studies may provide an appropriate perspective for understanding the transition to a CE. Ultimately, the paper aims to capitalise on these insights to contribute to the design of policy guidelines and organisational strategies.

In the ongoing sustainability debate, the circular economy (CE) has been steadily gaining ground as a new paradigm. At the same time, eco-innovation (EI) has been recognised as a key element in carrying out the transition from a linear to a circular system of production and consumption. However, little information can be found concerning whether and how EI can actually facilitate the change to a CE. While extensive literature on EI, and a growing body of research exploring the CE, already exist, there is, as yet, no comprehensive understanding concerning the connections between these two concepts. Drawing on academic contributions from the fields of EI and CE, this analysis seeks to clarify and synthesise findings at the intersection of these two fields. The aim is threefold: derive literature-based working definitions of CE and EI; review the role of EI at CE's macro, meso, and micro levels; and characterise CE-inducing EI in terms of targets, mechanisms and impacts. Our literature review shows that an EI-driven techno-economic transition to a CE requires specific solutions, i.e. different forms of EI-driven “clean congruence” at distinct levels of operation. Generally speaking, movement toward a CE is found to be contingent on “systemic” EI, that is, not only intense in technology but also involving dynamic and holistic combinations of service innovations and novel organisational set-ups.

The concept of circular economy (CE) is to an increasing extent treated as a solution to series of challenges such as waste generation, resource scarcity and sustaining economic benefits. However the concept of circularity is not of novel as such. Specific circumstances and motivations have stimulated ideas relevant to circularity in the past through activities such as reuse, remanufacturing or recycling. Main objectives of this work are: to provide a comprehensive review of research efforts encompassing aspects of resources scarcity, waste generation and economic advantages; to explore the CE landscape in the context of these three aspects especially when they are considered simultaneously; based on an idea of a comprehensive CE framework, propose an implementation strategy using top-down and bottom-up approach in a concurrent manner. To fulfill this objective a comprehensive review of state-of-the-art research is carried out to understand different ideas relevant to CE, motivation for the research and context of their recurrence. Main contributions of this paper are a comprehensive CE framework and a practical implementation strategy for a regenerative economy and natural environment. The framework emphasizes on a combined view of three main aspects i.e. environment, resources and economic benefits. It also underlines that joint support of all stakeholders is necessary in order to successfully implement the CE concept at large scale. The proposed framework and implementation strategy also identify new avenues for future research and practice in the field of CE.
