This review aims to streamline the approach assessing most used valorization methods for fruit and vegetable waste (FVW) that are eco-friendly, cost-effective, sustainable within a circular economy framework. Green processing technologies extraction of bioactive compounds from FVW, their applications, technico-economical assessment FVW’ biorefinery support highlighted. Important value-added products generated by FVW include compounds, pectin, protein isolates, such as soy, natural pigments anthocyanins, quinones, carotenoids, betalains, chlorophyll. At this time, prospects using have increased in food supplements, edible packaging, agriculture, energy, water purification fields. The findings report proper management not only minimizes addition landfills absence composting, but also promotes efficient utilization resources development innovative materials with wide range beneficial applications. Implementing possible solutions described paper would reduce environmental impact, open up new economic opportunities through FVW.

Optimization of biohydrogen production by dark fermentation of African food-processing waste streams

International Journal of Hydrogen Energy, Journal Year: 2023, Volume and Issue: 49, P. 266 - 276

Published: Aug. 16, 2023

In the challenge of mitigating greenhouse gases produced mainly by fossil fuels, recovery agricultural and food waste to produce biohydrogen dark fermentation is considered a promising source for future. However, industrial-scale production remains challenging several parameters significantly influencing application technology need be finely tuned. present study, an evaluation from cassava pineapple waste, widely available in many African countries, was carried out using different microbial consortia originating industrial biogas plants Italy. The defined both screening most appropriate inoculum "centered composite design" optimize pretreatment time pH. From which abundant starch (43%), highest hydrogen levels (62.32 mL H2/gVS) were obtained at pH 7.72 adopting 4-h heat treated anaerobic digester fed with corn barley silage. Higher yields (75.50 achieved 6 once pineapple, has high content hemicellulose, converted another selected inoculum, isolated olive pomace treating plant, where hemicellulose one common polysaccharide. correlation coefficients R2 adjusted are close unity, proving model express concentration produced. This combined approach performed successfully represents strong strategy residues even contexts.

Elucidating the role of pH and total solids content in the co-production of biohydrogen and carboxylic acids from food waste via lactate-driven dark fermentation

Fuel, Journal Year: 2023, Volume and Issue: 338, P. 127238 - 127238

Published: Jan. 6, 2023

Notwithstanding lactate-driven dark fermentation (LD-DF) can cope with inhibition issues associated the over-proliferation of lactate producers, there is still a knowledge gap about role key operational parameters. In this study, effect pH and total solids (TS) content on co-production hydrogen carboxylic acids, including medium-chain acids (MCCAs), from food waste (FW) via LD-DF was investigated. A series batch fermentations conducted, first, without control, then at fixed values 5.5, 6.0 6.5, while maintaining constant TS 5 %. It observed that higher pH, lower accumulation extent rate production, sustaining maximum production yield 81 NmL/g VS fed 9 NL/L-d, respectively, 6.5. second tests, adjusted to 5, 7.5 10 % set The highest performance (103 NmL/g-VS 13.3 NL/L-d) achieved TS, which also resulted in MCCAs, particularly caproate, an titer 8.7 g/L. Hydrogen plateaued exhaustion regardless condition tested. Further assessment through biochemical methane potential tests showed effluents be alternatively valorised into biogas. Overall, results obtained confirmed FW suggested non-conventional route may alternative approach flux diverted toward undesirable non-hydrogen-producing metabolic pathways.
