Sustainable Management Strategies for Fruit Processing Byproducts for Biorefineries: A Review

Abstract

The fruit processing industry generates enormous amounts of byproducts, which are primarily removed through landfill or incineration. However, these processes cause carbon dioxide and methane emissions and release dioxin into the environment. The management of fruit processing byproducts is important for reducing the amount of food waste that is sent to landfills and for developing strategies through the reuse of these products for valorization and economic added value. Fruit processing byproducts are rich sources of bioactive compounds and fermentable and nonfermentable sugars. Therefore, these materials are very attractive feedstocks for developing integrated multifeed biorefineries that coproduce a wide range of natural products and bioenergy. The studies presented here have shown sustainable strategies for managing fruit processing byproducts via a biorefinery approach to achieve full valorization via a circular economy. The full valorization project proposed five main phases, namely, pretreatment, extraction, dark or aerobic fermentation, anaerobic digestion, and post-treatment, as well as two additional pathways to generate additional bioelectricity. When choosing the appropriate directions for the presented concept, a technoeconomic analysis should be carried out, considering the type of biomass and its availability at the site of the biorefinery and throughout the year of production. Applying the proposed concept of biorefineries in closed-loop technology is a promising way to enhance economic efficiency and decrease environmental influence in accordance with sustainable development.

“…Therefore, the reuse of these byproducts can lead to both economic and ecological benefits. Activities related to reduction, recycling, and reuse are part of the global trend associated with the concepts of sustainable development and consumption [1][2][3][4][5].…”

Data-Driven Strategies for Optimizing Albania’s Utilization of Renewable Energy Sources from Urban Waste: Current Status and Future Prospects

“…This transformative approach advocates for the optimization of resources through closed-loop systems, wherein products and materials are reused, recycled, and repurposed to minimize waste and environmental impact. The management of waste is an essential component in addressing the impact on the environment and it is something that a variety of industries can be involved in [4][5][6][7]. Albania, amidst its journey toward European Union integration, has emerged as a proactive participant in this transition, spearheading initiatives aimed at embracing the circular economy ethos [8].…”
