“…The National Pilot Circular Economy Zone Programme, launched by the State Environmental Protection Administration in 2001, and the laws that have been applied since 2003 to promote the circular economy, are examples of these measures. While not primarily aimed at promoting industrial symbiosis, they contribute to the spread of this practice by providing increased awareness of the importance of resource reuse and recognition of the fundamental role of the circular economy in China's development [23,24]. The China National Eco-Industrial Demonstration Programme launched in 2000 by the State Environmental Protection Administration [25] has also contributed to the increase in the number of potential industrial symbiosis cases and China's leadership in the publication of case studies [19].…”

Industrial symbiosis, which is characterised mainly by the reuse of waste from one company as raw material by another, has been applied worldwide with recognised environmental, economic, and social benefits. However, the potential for industrial symbiosis is not exhausted in existing cases, and there is still a wide range of opportunities for its application. Through a comprehensive literature review, this article aims to compile and analyse studies that focus on potential industrial symbiosis in real contexts, to highlight the margin of optimisation that is not being used. The cases reported in the publications identified here were characterised and analysed according to geographic location, type of economic activity, waste/by-products, main benefits, and the methods employed in the studies. From this analysis, we conclude that there is great potential for applications involving industrial symbiosis throughout the world, and especially in Europe, corresponding to 53% of the total cases analysed. Manufacturing stood out as the sector with the highest potential for establishing symbiosis relationships, and the most common types of waste streams in potential networks were organic, plastic and rubber, wood, and metallic materials. This article also discusses the main drivers and barriers to realising the potential of industrial symbiosis. The diversity of industries, geographical proximity, facilitating entities and legislation, plans, and policies are shown to be the main drivers.

“…Plastic represents one of the highest fractions of global waste by mass nowadays. This trend goes along with the increasing environmental concern for post-consumer plastic waste [23]. Its sale and reuse can increase the income for the university.Old tires: the number of vehicles is increasing, resulting in an increase in tire waste at the end of their useful life [29].…”

“…In this way, the campus inhabitants would achieve sustainable management and the University of Lome would be able to generate income and save energy. In addition, integrating the concept of circular economy on the campus could be considered an effective strategy that, not only reduces post-consumer waste pollution, but also mitigates greenhouse gas (GHG) emissions [23]. This is very important, as the University of Lome (the main university of Togo) serves as a model for the rest of the country and, consequently, would be providing value at a national level so that Togo could pave the way for a circular economy model in the future.…”

The circular economy aims to reduce the volume of waste generated in the world, transforming it into resources. The concept of indicator of circular economy was introduced to evaluate the improvement obtained regarding efficiency in terms of reduction, reuse and recycling of waste generated on the campus of the University of Lome (Togo). These indicators showed that 59.5% of the waste generated on the campus in 2018 could be introduced into the circular economy paradigm through composting, and 27.0% of the energy consumed could be replaced by clean energy obtained from biogas. The entire plastic fraction can be introduced into the circular economy paradigm by reusing plastic bottles and selling the rest in the port of the city. Thus, the income obtained could range from €15.5/day in 2018 to €34.5/day in 2027. Concerning old tires, 1.5% of the rubber needed to pave the entire roadway of the campus could be replaced by the waste generated by the tires currently existing there. Consequently, waste management on the campus could be controlled thanks to these indicators, and this could serve as a model for the rest of the country.

Towards a Circular Economy: A Case Study of Waste Conversion into Housing Units in Cotonou, Benin

Cotonou is the largest city and main economic centre of the nation of Benin, Africa. Following independence, the city has experienced major population growth resulting in the extensive development of slums on flood plains and marshes causing the loss of biodiversity of these fragile ecosystems. Infrastructural development, unable to keep pace with informal settlement development, and a cumbersome municipal service system, have led to the illegal dumping of organic and plastic wastes, and extensive land pollution. In addition, due to its primary dune coastal location, Cotonou is facing sea level rise risks demonstrating the urgent need to sustainably address urban development. Through a socio-technical framework, this paper considers the use of transformed plastic wastes as new settlement building blocks to reduce solid waste, create jobs, and develop low-cost housing. This new strategy offers employment empowerment and a strategy to generate an income of US$2,380,000 per annum and the creation of 3200 permanent jobs.
