“…where D is the crystallites' size (nm), K is the crystal shape factor which was be taken as 0.9, λ is the wavelength of the X-ray radiation (0.154050 nm), β is the full width at half maximum (FWHM), and θ is the peak position of the XRD pattern. Morphological and elemental examination was conducted by means of Scanning Electron Microscopy (SEM), using a JEOL 6610LV [15]. The elemental analysis was carried out using an X-Max 80 (Oxford Instruments) Energy Dispersive Spectroscopy (EDS) detector attached to the SEM.…”

The current study presents an original chemical, elemental and mineralogical characterization of new quartz mineral deposits situated in Ios island, Cyclades, Aegean sea, Greece, via X-Ray Diffraction (XRD), Scanning Electron Microscopy with Energy Dispersive Spectroscopy (SEM-EDS) and Inductively Coupled Plasma Mass Spectrometry (ICP-MS) trace-element analysis. Actually, the mineral Quartz (crystalline SiO2) is found in nature in varying quality and is explored and traded for use in different applications of significant importance depending on the quartz purity. The results of the thorough chemical and mineralogical analysis indicate that quartz originating from the location examined in this research is almost free from other microcrystalline phases, and therefore it can be characterized as highly pure α-quartz. Thus, it can be used in the industry of ultra-high purity quartz production for specific applications, as long as the deposits are exploitable. In this framework, a preliminary estimation of the economic benefits from a potential exploration versus the environmental aspects of mining, taking into account sustainability issues in the region, is provided highlighting the local social needs

“…and feed, increasing the phenolic and unsaturated fatty acid contents, fiber content, and the oxidative stability of these products, among other effects 45. Other applications have been found for olive pomace such as a fertilizer and for energy purposes (production of methane and syngas) 45, 46 and as an additive in materials to improve properties like resistance to oxidation‐induced cracking 47 and reduce thermal conductivity 48. Moreover, it can be used as a source of lignin 41, phenolic compounds 49, 50, and pectins 51, which are objects of study in Sect.…”

The olive oil sector generates a high quantity of biomasses every year, especially in the Mediterranean region. Olive pomace is the main one, but depending on the extraction and subsequent processing, other derived biomass by‐products are generated like pâté, exhausted olive pomace, olive stone, and residual pulp. Their sustainable valorization is crucial. Therefore, this review first conceptualizes the current situation of the olive oil sector and describes these biomasses from a qualitative and quantitative point of view. Second, information on the bioactive compounds they present, the technologies used for their extraction, and examples of applications for their extracts is provided. Third, since the extraction of bioactive compounds will generate new residual biomasses, this review takes a step forward by integrating the extraction step in biorefinery cascading schemes. It also analyzes the benefits of this integration, the contribution to a circular (bio)economy, and the achievement of sustainable development goals.

“…The possible incorporation of olive pomace into clay bodies for developing ecofriendly ceramic materials has been positively assessed [75,80], although results from a Life Cycle Assessment (LCA) indicate that associated environmental benefits are very limited [77]. Biomass bottom ash deriving from the combustion of olive cake or olive pomace together with almond shell can act as alkaline activator to develop chamotte-based geopolymers as substitutes for ceramic bricks [81].…”

Available Pathways for Operationalizing Circular Economy into the Olive Oil Supply Chain: Mapping Evidence from a Scoping Literature Review

et al. 2021

Circular economy (CE) is increasingly seen as a promising paradigm for transitioning agri-food systems towards more sustainable models of production and consumption, enabling virtuous and regenerative biological metabolisms based on strategies of eco-efficiency and eco-effectiveness. This contribution seeks to provide a theoretical and empirical framework for operationalizing the CE principles into the olive oil supply chain, that plays a central role in the agroecological systems of the Mediterranean region. A scoping literature review has been conducted in order to identify the available pathways so far explored by scholars for reshaping the olive oil supply chain from a circular perspective. The analyzed literature has been charted on the base of the circular pathway examined, and according to the supply chain subsystem(s) to which it refers. Results are discussed highlighting the main issues, the technology readiness level of the available pathways, the prevailing approaches and knowledge gaps. A synthetic evidence map is provided, framing visually the scrutinized pathways into the Ellen MacArthur Foundation’s CE ‘butterfly’ graph. The work is intended to be a valuable baseline for inquiring how circularity can be advanced in the specific supply chain of olive oil, and which are the strategic opportunities, as well as the barriers to overcome, in order to foster the transition.
