The use of biowaste for the production of biodegradable superabsorbent materials

Abstract

Climate change, the large accumulation of waste, the generation of microplastics, and the recent scarcity of raw materials are some of the problems that have led to a radical change in the conception of economy from a linear system to a circular system. Thus, different policies, such as the European Green Deal or Horizon Europe, have been created on these aspects. In this context, the use of biowaste for the production of superabsorbent materials can be a clear example of how circular economy can be applied. This opinion review aims to be a global view of these initiatives, presenting examples of the use of different biowaste in superabsorbent materials and explaining the deficiencies that have prevented their inclusion in the market. This review shows that, although the use of biowaste seems to be a key factor for change, further research is needed to make the products more competitive in the current market.
