Persea Americana Agro-Industrial Waste Biorefinery for Sustainable High-Value-Added Products

Abstract

Significant problems have arisen in recent years, such as global warming and hunger. These complications are related to the depletion and exploitation of natural resources, as well as environmental pollution. In this context, bioprocesses and biorefinery can be used to manage agro-industrial wastes for obtaining high-value-added products. A large number of by-products are composed of lignin and cellulose, having the potential to be exploited sustainably for chemical and biological conversion. The biorefinery of agro-industrial wastes has applications in many fields, such as pharmaceuticals, medicine, material engineering, and environmental remediation. A comprehensive approach has been developed toward the agro-industrial management of avocado (Persea americana) biomass waste, which can be transformed into high-value-added products to mitigate global warming, save non-renewable energy, and contribute to health and science. Therefore, this work presents a comprehensive review on avocado fruit waste biorefinery and its possible applications as biofuel, as drugs, as bioplastics, in the environmental field, and in emerging nanotechnological opportunities for economic and scientific growth.

"Synthesis, Characterization, and Electrochemical Study of ZIF-8 Metal Organic Framework and its Application as Catalyst for Glucose to Fructose Conversion and 5-Hydroxymethyl Furfural "

“…Peaks with high intensities (112), (022), and (044) confirmed the formation of ZIF-8 NPs. These findings were compared to previously reported literature [17,18] and found to be comparable.The structure of the ZIF-8 material based on hkl values are 222 and 235.…”

“…In this regard, the valorization of plant biomass is critical in terms of environmental protection [15][16]. Renewable natural resources play an important role in economic activity [17][18]. Several natural resources have been investigated as potential sources of bio-products in this context.…”

“…La biorrefinería es como la refinería del petróleo, pero en lugar de emplear petróleo como material de partida, emplea biomasa para la obtención de materiales y energía, y todo lo positivo que implica para el medio ambiente. Como se observa en la figura 11, de diferentes tipos de procesos (químicos, enzimáticos, mecánicos, entre otros), es posible obtener productos de alto valor agregado como la lignina, la celulosa y el almidón, además de la fermentación de los jugos (dextranos), empleando métodos enzimáticos o microrganismos como el Leuconostoc mesenteroides (Menezes et al, 2021;Lecot et al, 2021;Mora-Sandí et al, 2021).…”

Green Synthesis of Antibacterial Silver Nanocolloids with Agroindustrial Waste Extracts, Assisted by LED Light

“…Ecuador is an agroindustrial country where several tropical crops are traditionally cultivated and exported worldwide, cacao beans and bananas being the main export goods [3]. The worldwide consumption of crops such as avocado and citrus fruits is growing; therefore, the production and export of these crops in Ecuador is also increasing [4][5][6]. These industries generate residues of around 2,200,000 tons; these residues are currently underutilized, and they pose a waste problem in Ecuador [7].…”
