The Circular Economy as a Creator of Value in Agribusiness 4.0: Proposals for a Life

The circular economy has come with momentum to settle in the countries as a new model of economic growth. Thus, sustainable development and the objectives set forth by the United Nations for its achievement and expansion highlight the concern and preoccupation of society for these issues. For this reason, this chapter deals with four specific aspects of the agricultural industry sector, which aim to improve our lives and the sustainability of our planet. These aspects refer to the use of biomass residues and their contribution to the food sector, the generation of biofuel and electricity from biogas for agricultural use, as well as the reuse of treated wastewater for irrigation. Finally, a decrease in cotton production and the use of regenerated cotton by the textile industry will be considered. Based on the theoretical framework, four specific proposals are established to achieve the aggregate global growth requirement posed by Sustainable Development Goal 8, compared to the reduction in the use of CO2, together with the reduction in the use of resources (Goals 6, 7, 9, 12 and 15). These proposals cover aspects such as the reuse of organic and biodegradable wastes, the reuse of water through different irrigation methods and its application based on its components, and the reuse of cotton from existing clothing. All of this provides economic agents, administration, companies, and households with opportunities for reflection and implementation of a more sustainable economic and social model.
