Sustainability and Circular Supply Chains

Ifeyinwa Juliet Orji, Frank Ojadi
Nevertheless, the open loop supply chains and circular economy's industrial symbioses collaborative emphasis entails a broader supply chain network perspective where supply chains from many industries share their low entropy wastes and by-products to be utilized as an input material. Industrial symbiosis is a central area of circular economy literature that depends on cooperative organizational behaviors to enable the emergence of an industrial ecosystem that simultaneously reduces the resource utilization of virgin input materials and the output of waste products and emissions. For example, a past published study presented the notion of “industrial chains” to emphasize the significance of collaboration between many supply chains in a larger supply chain network that usually covers over many industries. This suggests that a transition to circular supply chains is facilitated when the traditional upstream and downstream collaborative interactions are widened to involve organizations beyond the immediate industrial boundaries of a supply chain. Indeed, for many industries, the transition toward a circular economy is rather challenging because firms need to collaborate with actors within and beyond immediate industry boundaries. Businesses are more likely to establish vertical collaboration than horizontal collaboration during implementing circular economy initiatives.

Symbiosis means a local partnership, where it provides, share and reuse of resources to generate shared value (Chertow, 2007). The industrial symbiosis is a concept where two companies make an association in which waste or by-product of one is used as input by the other (Jacobsen, 2006). Figure 4.8 reprsents different motives to have industrial symbiosis. Industrial symbiosis is cooperation between two or more separate industries to exchange resources, by products or materials that are no longer of use to one, but of use to other (Baldassarre, 2019). It is beneficial from commercial as well as an environmental viewpoint. The application of this concept allows materials to be used more sustainably and contributes to the creation of a circular economy. It leads to reduction in the requirement of raw material, reduction of waste of associated carbon footprints (Cao et al., 2020). Moreover, industrial symbiosis generates new business opportunities for recyclers and trading companies.

Circular economy is a systemic shift that requires changes in current production and consumption patterns. Firstly new, innovative technologies must be developed and introduced (eco-innovation and eco-design). Besides the technological innovation, social and organizational innovation is inevitable. Secondly, the actors must change their interplay by giving repair, refurbishment, remanufacture and recycling higher importance. All these changes cannot be done if not supported by regulation (such as rethinking incentives, providing a suitable set of international environmental rules) and cultural shift in changing the manner of both consumers and producers. (Kirchherr et al. 2018, EEA 2016) Among the enabling factors, we would like to highlight the industrial symbiosis as a new business model, a local or global partnership where companies of different sectors collaborate to make one’s waste or by-product a resource for another. By providing, sharing and reusing resources industrial symbiosis can create loops of technical or biological materials and minimize waste. (PwC 2018, EEA 2016).
Energy and economic assessment of mixed palm residue utilisation for production of activated carbon and ash as fertiliser in agriculture

For environmental and economic impact using the combinational techniques of Lenzen et al. [33] based on the uncertainty analysis for multi-region input–output models – a case study of the UK's carbon footprint and Chertow and Lombardi [34] which centres on environmental costs with less attention to benefits. The environmental benefits of industrial symbiosis are quantified by measuring the changes in the consumption of natural resources, and in emissions to air and water, through increased cycling of materials and energy. The economic benefits are quantified by determining the extent to which companies cycling by-products can capture revenue streams or avoid disposal costs; those businesses receiving by-products gain advantage by avoiding transport fees or obtaining inputs at a discount.
Barriers and enablers of circular economy in construction: a multi-system perspective towards the development of a practical framework

Two approaches can be adopted in the use of enablers to drive CE implementation; the Top-down and the Bottom-up. This study through the multi-level analysis and expert considerations recommends the bottom-up approach as a more practical alternative for CE implementation with greater potential for integration within the built environment. A systematic bottom-up approach is needed to build effective collaborations between actors at same and other levels, build capacity and create an enabling environment for CE implementation. For instance, it is essential to promote stakeholder interest while providing access to funding initiatives for CE at the basic firm level first, before creating large markets for circular construction products for the industry. Innovation and technology, as well as circular business model development, are required to drive change at both the firm and inter-firm levels. Market creation and collaboration between organisations where industrial symbiosis is encouraged is needed to drive the transition. At the highest level, policy and regulations are vital to drive, city wide and national scale transitions. To further drive the implementation of CE within the construction industry, a holistic framework is needed, and awareness created through education to cut across all system levels of CE.
Economic and environmental implications of the interfirm waste utilisation

Industrial symbiosis is a nature-inspired solution and emulates the mutualism symbiosis of the natural ecosystem with an aim to reuse all the materials from production activities (Turken et al. 2020). The classic definition on IS from Chertow (2000) encourages traditionally separate industries to collaboratively involved in the physical exchanges of material, energy, water, and by-product and emphasises the crucial role of collaboration and geographical proximity in the formation of symbiotic relationships. One notable example is the Guitang Group which has evolved from a stand-alone refinery to an industrial symbiosis complex composed of interlinked production of sugar, pulp and paper, alcohol, and fertiliser by utilising the two key by-product streams from sugar production: molasses and bagasse (Zhu and Cote 2004; Zhu et al. 2007). Another example is the Tianjin Economic-Technological Development Area (TEDA), a National Eco-industrial Park Demonstration Program in China, where a series of industrial symbiosis activities involving energy and water cascading and solid waste exchanges have emerged among the four pillar industries (electronics, machinery and automobile, biomedicine, and food & beverage sectors) driven by the excessive scarcity of both water and usable land (Shi, Chertow, and Song 2010).
