“…An electrostatic approach using corona discharge has been successfully applied for cleaning and upgrading agricultural seeds (Kovalyshyn et al, 2013). Electrostatic separation of peelings and gluten from ground wheat grains was recently developed based on conductive induction charging of powders using a grounded metallic belt conveyor and a rotating roll electrode connected to a negative high voltage supply (Remadnia et al, 2014).…”

“…The less conductive particles, which retain more charge, are attracted by the roll A C C E P T E D M A N U S C R I P T 11 electrode and then collected by scraping, whereas the most conductive particles, which have lost their charge, stay on the belt where they are collected separately. A 50:50 mixture of material from finely-ground wheat grain peeling (corresponding to the outer pericarp) or from isolated gluten was conveyed on a belt-type separator (Remadnia et al, 2014). As pericarp and gluten exhibited similar conductive behavior, the corona charging was not an effective solution for efficient separation, so conductive induction was recommended.…”

This paper reviews studies on green resource fractionation for two different types of material displaying a lignocellulosic or granular-type structure or a composite of the two. It explains how the identification of specific biochemical or spectral markers helps monitor tissue fate along processing and thus increase our knowledge on material fractionation. The key role of tissue mechanical properties in fracture behavior and the value of characterizing them were highlighted to better understand particle composition and properties. The effect of different modes of mechanical stress and strain during grinding as the main step of fractionation was illustrated. The value of different types of pre-treatment before or at grinding to reduce energy required to fracture and enhance dissociation or compound accessibility was presented. Separation methods based on differences in properties of the generated particles, and particularly innovative developments based on electrostatic sorting, were reviewed.

“…Similarly, although in fact [23] were studying the separation of a synthetic mixture of 50% peel and 50% gluten originating from wheat grains, they showed that separation was more efficient when the particles were charged by induction, with 23% of peel recovered in the conductive fraction and 53% of gluten in the non-conductive fraction. The separation was hypothesized to be related to the big difference in particle size: small particles of gluten being attracted by the electrode because of their low mass, whereas big particles of peel remained on the conveyor belt because of their weight.…”

Today, most technologies used to fractionate plant materials are based on expensive chemical processes that often have negative environmental impacts by consuming water, energy, and solvents and creating large quantities of effluents. In addition, during the separation step, the major components are often partially degraded. Achieving high fractionation yields while maintaining the integrity of the macromolecular structure is a major challenge for the next generation of biomass refining processes. Electrostatic separation (ES), which enables the production of enriched fractions in compounds of interest while preserving their (native) functionalities has emerged as an ecofriendly biotechnology for the fractionation of agro-resources in dry conditions. In this review, the potential of ES in a biorefinery scheme is evaluated and the technological obstacles that still need to be overcome for its full deployment at industrial scale are identified.
