Globally, daunting plastic waste has become a grave ecological concern, which has mounted pressure on ecologists, government, businesses, and researchers to explore innovative opportunities to manage the situation. As a perceived panacea, the reverse supply chain is now an essential approach...

In this study, we examine multi-level, dual-channel green closed-loop supply chain (CLSC) that incorporates circular economy (CE) principles. We focus on the implementation of an incentive-based recycling program for customers, and the investigation of various CLSC settings, such as centralized,...

Motivated by mounting pressures to achieve environmental sustainability, and the emergence of online waste exchange platforms, in this work we propose an optimization-based framework for studying waste-to-resource formation in the industry. We first develop a linear programming market clearing...

Despite more consumers paying attention to recycling symbols and labels when they purchase plastic products, few plastic products are actually recycled into new commodities. Instead, many “recyclable” plastic products end up incinerated or disposed in landfills. Consumers and environmental...

We simulate the performance of a gain-sharing charging scheme aimed at boosting the circularity of municipal solid waste management; its effectiveness is empirically tested by comparing it with the performances of unit pricing and standard schemes. When unit pricing charging schemes are in...

A linear flow of materials and energy is not feasible to maintain if industries are meant to be sustainable. In an effort to embrace sustainability, automobile companies are shifting from internal combustion engines to electric vehicles and embracing Industry 4.0 technologies. A solution to the...

Circular economy (CE) can potentially contribute driving our society towards an ecological transition. An adequate legislative system is considered among the most effective manners to support firms in the adoption of circularity. However, there is little clarity on what are the most effective...

Australia has long been observed to experience ENSO (El Niño Southern Oscillation) of alternating flooding and drought. It is currently experiencing its fourth year of La Niña heavy rain and flooding. At some stage this will revert to one or more years of El Nino drought, often severe. In...

Socio-technical niche innovations offer significant opportunities to accelerate Africa's transition to a circular plastic economy. However, information on how these opportunities can be operationalised is fragmented, and stakeholder networks appear to be significantly under-developed on the...
