**4. Discussion**

Based on the groups identified through a bibliography of 1842 selected articles from six fields, the proposed framework for a circular economy and sustainability-oriented innovation is presented in Figure 8. In general, circular economy and sustainability-oriented innovation relies on establishing strategic options and taking a multi-level approach that incorporates stakeholders into the practice of a circular economy [9].

This strategy enables the exchange of knowledge, provision of higher quality raw materials, and the adoption of technology and information that enables faster transitions for companies to build appropriate conditions to seize opportunities and develop a circular economy and sustainability-oriented innovation. The impact of this provides an environmentally oriented development pattern to spread the proposition of environmental values globally and to innovate, in a sustainable manner, towards the achievement of sustainable development goals (SDGs).
