“…The emerging concept of biorefineries (142,143,156) may open new approaches to valorizing FLW by enabling the extraction of high-value active compounds from FLW material flows (142,157,158) (Table 3). Beyond extraction of high-value biochemical compounds, biorefining can develop products that enhance ecosystem services, especially for crop production, including conversion of FLW to alternative fertilizers and fumigants (159)(160)(161).…”

“…Beyond extraction of high-value biochemical compounds, biorefining can develop products that enhance ecosystem services, especially for crop production, including conversion of FLW to alternative fertilizers and fumigants (159)(160)(161). However, biorefining techniques still require more research and are not currently a commercially viable solution for large-scale treatment of FLW (146,156).…”

It has been estimated that one-third of global food is lost or wasted, entailing significant environmental, economic, and social costs. The scale and impact of food loss and waste (FLW) has attracted significant interest across sectors, leading to a relatively recent proliferation of publications. This article synthesizes existing knowledge in the literature with a focus on FLW measurement, drivers, and solutions. We apply the widely adopted DPSIR (Driver-Pressure-State-Impact-Response) framework to structure the review. Key takeaways include the following: Existing definitions of FLW are inconsistent and incomplete, significant data gaps remain (by food type, stage of supply chain, and region, especially for developing countries), FLW solutions focus more on proximate causes rather than larger systemic drivers, and effective responses to FLW will require complementary approaches and robust evaluation.

“…Many wastes are also generated from the winery industry, mainly from Southwestern Europe (Italy, France, Greece, Portugal, and Spain), which is responsible for almost 50% of worldwide wine production. 1 In Greece, for example, ∼5 MhL of wine are produced per year, 18 resulting in about 5 tons of waste per hectare of land, during cultivation and harvesting, and in 650,000 m 3 of winery wastewater. 19 Portugal is the 12th wine producing country worldwide with 6.6 MhL in 2017, 20 and therefore, the amount of winery wastes generated is, at least, similar to Greece values.…”

The concept of bioeconomy has been promoted worldwide in order to replace fossil-based resources and to find new strategies for waste management, by converting biomass into energy, chemicals, and value-added products, in a sustainable way. Despite the efforts that have been made in this area, there are still some unexplored raw materials globally, namely from agricultural and forestry industries. Therefore, the aim of this work was to characterize four abundant residues from the Portuguese agroforestry industry, including pruning residues (pine branches, PB) and stumps (PS), tomato waste (TW), and winery wastewater (WW), for analyzing their potential within the biorefinery context. Volatiles were analyzed by gas-chromatography, and compounds with repellent/attractant properties were found for PB and PS, while flavor-enhancers were particularly identified in agrowastes. Composition analysis revealed that both TW and WW had the potential for biogas generation (BMP ∼340 and ∼250 NL CH4/kg VS, respectively), whereas forestry residues (PS and PB) can be recovered for thermal energy (HHV ∼20 MJ/kg) and bioethanol production (∼0.3−0.4 L/kg). Among all the aqueous extracts that were obtained, PS showed both the highest antioxidant activity (IC 50 ∼6 μg/mL) and total phenolic content (∼400 mg GAE/g extract). All residues were demonstrated to be promising for the Portuguese biobased economy.

“…The use of all raw material flows in accordance with the concept of circular economy and zero waste generation, embracing all pillars of sustainability, i.e. the environment, society, and the economy, is one of the main premises of biorefineries (108). Therefore, new refining approaches have been proposed for conversion of dairy by-products into valuable bio-based products (e.g.…”

The dairy industry produces large amounts of whey as a by- or co-product, which has led to considerable environmental problems due to its high organic matter content. Over the past decades, possibilities of more environmentally and economically efficient whey utilisation have been studied, primarily to convert unwanted end products into a valuable raw material. Sustainable whey management is mostly oriented to biotechnological and food applications for the development of value-added products such as whey powders, whey proteins, functional food and beverages, edible films and coatings, lactic acid and other biochemicals, bioplastic, biofuels and similar valuable bioproducts. This paper provides an overview of the sustainable utilisation of whey and its constituents, considering new refining approaches and integrated processes to covert whey, or lactose and whey proteins to high value-added whey-based products.
