Recovery of Raw Materials and Obtaining Functional Carbonaceous Materials from the Circular Economy of Organic Waste

This chapter addresses on the recovery of raw agro-industrial materials and its use to prepare functional carbonaceous materials from a per the circular economy of organic waste perspective. In particular, the first section focuses on the methods to extract high-value substances and to obtain microbial metabolites from organic wastes. Later on, the use of experimental strategies as statistical optimization tools for organic waste recovery is discussed. In addition, an overview is given on the preparation of functional carbonaceous materials to be used not only as adsorbents but also as electrodes in the field of electrochemical advanced oxidation processes. Trends and perspectives for carbonaceous materials obtained from agro-industrial wastes are also discussed in this study.
