Olive pomace (OP) is a lignocellulosic waste from olive oil industry. In order to valorize these wastes as flame retardant (FR) fillers into polymers, OP residues are milled and screened into three different fractions. Two strategies are then investigated. The first one is to modify OP particles by phosphorus molecules using radiation grafting as already done successfully with flax. Nevertheless, pyrolysis combustion flow calorimetry analyses show that the introduction of phosphorus does not promote charring of OP and flame retardancy is not significantly improved whichever the considered fraction. The second strategy is to replace pentaerythritol by OP as char source into well-known FR systems based on ammonium polyphosphate. The incorporation of such system into ethylene-vinyl acetate copolymer leads to satisfying FR performances according to cone calorimeter tests. Moreover, the presence of high amount of extractives into OP such as oleic acid does not appear detrimental.

“…Reinforcing fillers can be easily produced by dry fractionation of a given lignocellulosic biomass, by combining dry grinding and sorting processes (Berthet et al, 2017;Lammi et al, 2018). Dry fractionation enables to avoid the consumption of water or chemicals and therefore generates very little waste (Lammi et al, 2018). 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.…”

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.

Komina masline kao ostatna materija u prehrambenoj industriji ne ubraja se u opasni otpad ili otpad općenito. To je potencijalni problem zbog njezinih određenih komponenata koje negativno utječu na ekosustav, a osobito na vodene organizme i biljke. Uslijed neadekvatnog odlaganja, spojevi komine bivaju isprani i procjeđivanjem dospijevaju u tla i podzemne vode gdje uzrokuju onečišćenja. Tema privlači dodatan interes zbog potencijala iskorištavanja komine masline u raznorazne svrhe, te je predmet mnogih znanstvenih istraživanja današnjice.
