“…Lama-Muñoz et al proposed a multi-step process that could allow an integral use of olive stone from the point of view of a biorefinery plant [ 129 ]. They proposed an initial aqueous extraction at 130 °C for 90 min without acid addition and a solid:liquid ratio of 1:2 ( w/w ), useful to recover liquors with higher phenolic content and antioxidant capacity.…”

Extra-virgin olive oil (EVOO) contains many bioactive compounds with multiple biological activities that make it one of the most important functional foods. Both the constituents of the lipid fraction and that of the unsaponifiable fraction show a clear action in reducing oxidative stress by acting on various body components, at concentrations established by the European Food Safety Authority’s claims. In addition to the main product obtained by the mechanical pressing of the fruit, i.e., the EVOO, the residual by-products of the process also contain significant amounts of antioxidant molecules, thus potentially making the Olea europea L. an excellent example of the circular economy. In fact, the olive mill wastewaters, the leaves, the pomace, and the pits discharged from the EVOO production process are partially recycled in the nutraceutical and cosmeceutical fields also because of their antioxidant effect. This work presents an overview of the biological activities of these by-products, as shown by in vitro and in vivo assays, and also from clinical trials, as well as their main formulations currently available on the market.

In another work on a biorefinery based on olive stones, a fractionation strategy is proposed to consecutively produce an antioxidant liquor using aqueous extraction, pentose‐rich liquor by dilute acid pre‐treatment, glucose rich liquor by enzymatic hydrolysis, and finally, lignin‐rich residual solid, with each fraction having a wide range of potential applications A biorefinery based on olive pomace .…”

Olive trees are cultivated in more than 40 countries worldwide over more than 10 million hectares. In addition to olive oil, a large amount of biomass is produced annually. All this biomass must be adequately handled and disposed of. Conventional disposal methods include direct burning or spreading in fields, but this has economical costs and environmental concerns, as well as wasting a source of energy and chemicals. This review summarizes the most recent proposals for the use of biomass derived from olive tree cultivation and olive oil production processes. Biomass produced from pruning, leaves, olive stones and pomace, extracted olive pomace, and olive waste water are considered, and the main options for processing are reviewed according to recent advances in the literature. The biorefinery concept applied to olive‐derived biomass is also presented and representative works are discussed. © 2017 Society of Chemical Industry and John Wiley & Sons, Ltd

“…The tropical exotic fruit by-products contain also a great variety of antioxidant compounds that could be used for the formulation of nutraceuticals (Ayala-Zavala et al, 2011). Other successful example byproduct that can show a good profitability for the extraction of phenolic compounds is olive-derived biomass (Nadour et al, 2012;Lama-Muñoz et al, 2014;Ruiz et al, 2017). The potato processing industry also generates significant amounts of waste that have been investigated for the extraction of phenolics compounds (Singh et al, 2011;Sabeena Farvin et al, 2012).…”

The society and industrial sectors are facing important challenges regarding the production of bioproducts influenced by social responsibility and environmental consequences. Biorefinery development reports two important goals in the transition towards a bio-based economy: i) the displacement of fossil-based products by biomassbased ones and ii) the setting up of a strong bio-based industry. In this sense, research is being addressed into bio-based products opportunities from biomass residues with the aim of obtaining promising building blocks and high-added value products.Environmental and economic analysis of some bioproducts can be found in the literature. However, social dimension of sustainability is regularly forgotten although many attempts have been performed to standardize and provide the procedures to assess the social dimension. This chapter presents the production of potential bioproducts from agri-food industrial sector and assesses their sustainability from environmental and social perspectives with the aim of identifying potential hotspots. Since the methodology to assess environmental consequences is well-known and standardised, special attention is paid on the selection of the social indicators considered for analysis. To do so, social impact assessment is conducted through involved stakeholders, surveys and field experiments. Thus, the methodology to assess the social dimension has been formulated in detail considering very different social well-being based indicators.
