| Abstract | The bioeconomy is considered one of the three main sectors with the greatest opportunities for the development of the circular economy in Brazil, who is one of the largest silk producers in the world; and sericulture is an agribusiness that contributes greatly to the bioeconomy in Brazil. Therefore, this research aimed to identify opportunities for creating value by internalizing flows in the production of silk cocoons by promoting a circular bioeconomy. To that end, a tool was used to assess the circularity of the referred system. The current circularity of the production of silk cocoons, at the farm level, is 74.19 % for material, and 0 % for energy. A range of measures are proposed, based on (i) engaging with reverse logistics practices, (ii) establishing a local agroindustrial cooperative, and (iii) building community biodigesters, which aid a potential circularity of 85.51 % (material), and 100 % (energy) at the farm level, and 98.42 % (material) and 100 % (energy), at the cooperative level. On top of increasing circular value, the proposed measures might bring environmental benefits, such as lessening environmental impacts of logistics (by valuing local resources) and replacing non-renewable energy, and social impacts, through increased quality of life for sericulturists. Economic implications need further investigation and are suggested to be addressed in future research endeavors, along with policy implications for the development of a circular bioeconomy. Furthermore, an increased circularity can also contribute to a few of the sustainable development goals (SDGs) proposed by the United Nations, such as SDGs 2, 7, 9, 11, 12 and 13. |
