“…The extraction moderately improved the material stability, with onset temperatures at 7 and 8 • C higher than the virgin fillers for ViSh-E and WiPo-E, respectively. The same results were observed for the enzymatically-treated rice endosperm [50].…”

Two winery residues, namely vine shoots (ViSh) and wine pomace (WiPo), were up-cycled as fillers in PHBV-based biocomposites. Answering a biorefinery approach, the impact of a preliminary polyphenols extraction step using an acetone/water mixture on the reinforcing effect of fillers was assessed. Biocomposites (filler content up to 20 wt%) were prepared by melt-mixing and compared in terms of final performance (thermal, mechanical and barrier). It was shown that the reinforcing effect was slightly better in the case of vine shoots, while it was not significantly affected by the pre-treatment, demonstrating that these two winery residues could be perfectly used as fillers in composite materials even after an extraction process to maximize their potential of valorization.

“…These can then be valorized for the production of bio-composite materials obtained by mixing a biopolymeric matrix (e.g., PHA, PLA, PBS and PCL) and a defined percentage of reinforcing bio-fillers, such as plant-derived fibers. As natural fibers are renewable, biodegradable, available in large amounts and cheap, they are particularly interesting for the preparation of polymer composites where they can improve the mechanical properties of the matrices and reduce the amount of expensive bio-polymeric matrix present in the final material [108,109]. The residues remaining after protein extraction from legumes have been exploited for the preparation of bio-composites together with polyhydroxyalkanoates (PHAs) as a biodegradable polymeric matrix [110].…”

The world is confronted with the depletion of natural resources due to their unsustainable use and the increasing size of populations. In this context, the efficient use of by-products, residues and wastes generated from agro-industrial and food processing opens the perspective for a wide range of benefits. In particular, legume residues are produced yearly in very large amounts and may represent an interesting source of plant proteins that contribute to satisfying the steadily increasing global protein demand. Innovative biorefinery extraction cascades may also enable the recovery of further bioactive molecules and fibers from these insufficiently tapped biomass streams. This review article gives a summary of the potential for the valorization of legume residual streams resulting from agro-industrial processing and more particularly for pea, green bean and chickpea by-products/wastes. Valuable information on the annual production volumes, geographical origin and state-of-the-art technologies for the extraction of proteins, fibers and other bioactive molecules from this source of biomass, is exhaustively listed and discussed. Finally, promising applications, already using the recovered fractions from pea, bean and chickpea residues for the formulation of feed, food, cosmetic and packaging products, are listed and discussed.

“…Moreover, fibres can be present also in the final solid residue obtained after extraction processes of high-value bio-active molecules, such as polyphenols, from agro or food processing by-products. Also this fibrous residue can find a final exploitation in reinforcing polymeric materials (Totaro et al, 2018). Biocomposites from lignocellulosic residues appear as innovative and promising materials for many sectors, including horticulture, building, automotive and packaging, provided that the presence of prohibitive contaminants can be discarded (Berthet et al, 2016).…”

Agricultural waste is a huge pool of untapped biomass resources that may even represent economic and environmental burdens. They can be converted into bioenergy and bio-based products by cascading conversion processes, within circular economy, and should be considered residual resources. Major challenges are discussed from a transdisciplinary perspective, focused on Europe situation. Environmental and economic consequences of agricultural residue management chains are difficult to assess due to their complexity, seasonality and regionality. Designing multi-criteria decision support tools, applicable at an early-stage of research, is discussed. Improvement of Anaerobic Digestion (AD), one of the most mature conversion technologies, is discussed from a technological point of view and waste feedstock geographical and seasonal variations. Using agricultural residual resources for producing high-value chemicals is a considerable challenge analysed here, taking into account innovative eco-efficient and cost-effective cascading conversion processes (bio-refinery concept). Moreover, the promotion of agricultural residuesbased business is discussed through industrial ecology, to promote synergy, on a local basis, between different agricultural and industrial value chains.
