“…Looking at the extraction step, a viable green alternative (compared with the conventional using solvent) is represented by extraction with supercritical CO 2 as it reduces the environmental footprint (Coelho et al ., ). In fact, conventional extraction with n‐hexane represents the current technique typically applied in an attempt to reuse the seeds biomass, however, the solvent is characterised by some negative aspects (e.g.…”

Traditionally, wine production has been assumed as an environmentally friendly process. However, it requires a considerable amount of resources (e.g. water, fertilisers and organic amendments), and, at the same time, producing a large amount of waste and by-products. Environmental analysis of the wine making process reports that organic solid wastes and wastewater represent the main effluents of the sector. This review aims to make an overview about the recent insights and results related to valorisation of grape pomace and how this approach, considering the number of dedicated studies, is now reaching its maturity. By-products valorisation, a concept increasingly consolidated in the field of industrial residues management, holds immense potential for prospective production. In this regard, the valorisation of grape pomace is proving its effectiveness, obtaining remarkable results.

“…The value of k f for each case studied was estimated following Coelho et al [33], who used the relation of Wilke and Chang [35]. The k f values obtained were then set as constants in the kinetics model, thus reducing the degrees of freedom.…”

“…Recently, there were attempts to represent some vegetable oils as a mixture of several TAGs, with a varied successfrom a failure in the prediction of the phase equilibrium of the multicomponent mixture examined [32] to an acceptable quantitative and qualitative representation of the kinetic curves measured [33].…”

“…In view of the above, we chose triolein as the TAG to represent the chia seed oil, which was motivated by two reasons: 1) there are experimental data available on the VLE of the binary triolein + scCO 2 and 2) the estimated thermophysical parameters of triolein used by us have been proved to represent in an acceptable way the VLE of the system [33].…”

A B S T R A C TThe kinetics of the supercritical fluid extraction of edible and discarded chia seeds was studied and modelled for the first time. The total oil was removed at 45 MPa and 60 C after 240 min. The extraction kinetics was simulated using a dynamic model in gPROMS ModelBuilder environment and the kinetic parameters estimated. Triolein was chosen as a model compound of the chia oil. The agreement between the experimental yields and those calculated by the model was good with deviations in the range (1.2-6.6) %, except at 25 MPa and 60 C (AARD = 9.5%).

Research and technology development in the field of residual biomass exploitation for the production of biofuels is advancing. Non-food waste could form an excellent feedstock for biofuel generation. Residual biomass of food or first generation biofuels industries forms an ideal feedstock for fuel production forming simultaneously an environmentally friendlier solution for their disposal. A number of challenges are associated with waste-biomass exploitation as collection, transportation and their management can dramatically affect the economics of the processes. The economics can however be improved if added value products are extracted prior to their treatment for biofuels. Furthermore, technological challenges related to feedstock quality and quantity variations have to be resolved. In this section, promising biomass for the characterization and the potential exploitation of which, substantial research is already in place is presented. The relevant biomass is, or has the potential to be abundant and its exploitation in the near future is realistic and possible.
