Valorization Strategies for Agriculture Residue: An Overview

Agricultural residues or waste represent a significant portion of current global solid waste output. It is detrimental to the environment, society, and economy if fails to integrate into the recycling chain. These residues are rich in organic and inorganic components and offer hidden opportunities for the production of specialty compounds and materials. This potential has been harnessed in recent years through biochemical, thermochemical, and biotechnological approaches to create a variety of bioproducts, including biofuels, bioplastics, biopolymers, biochar, biofertilizers, metabolites, nanocomposites, and specialty chemicals with credible applications in agriculture, food, pharmaceuticals, energy, and environmental remediation sectors. Additionally, contemporary technologies such as nanotechnology, artificial intelligence (AI), machine learning (ML), and the Internet of Things (IoT) have been utilized to enhance the accessibility and efficiency of valorization processes and functional byproducts. This chapter explores the fundamental principles and advancements in various valorization techniques as well as their benefits and challenges. It also examines the socioeconomic implications of agricultural residue valorization in fostering a circular economy and promoting a more sustainable and resource-efficient agricultural landscape.
