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

Among the most important agro‐industrial activities in the Mediterranean basin, olive oil production has a high impact on the economy of many Mediterranean countries. However, olive oil extraction generates huge quantities of byproducts, including leaves, pomace residues, stones and wastewater, which have severe environmental impacts mainly because of their phytotoxicity and great organic content. Olive oil byproducts are regarded as inexpensive and abundant raw materials rich in bioactive compounds with high and varied health‐related activities. Several phenolic compounds and terpenoids were recovered from olive byproducts using different conventional and advanced extraction methods due to their potential to be used in food, packaging, pharmaceutical, and cosmetic industries. Recently, the use of olive byproducts and their functional compounds to enhance the functional properties of packaging systems was investigated as a sustainable strategy for food preservation, fostering the sustainability of the olive‐oil chain, and promoting circular economy. In this framework, the main goals of this review are to summarize the main bioactive compounds in olive byproducts, to review the main advancements in their extraction, purification, and characterization, and finally to discuss their applications in food packaging systems as well as safety‐related aspects.

“…A range of interesting valorization options for such byproducts have been already proposed, including: recovering bioactive compounds; producing biofuel or bioenergy; manufacturing sustainable building materials; fertilizing or irrigating soil; practicing regenerative agriculture; feeding livestock; producing polymeric biomaterials; providing sorbents for aqueous effluents; synthetizing bio-fertilizers or biostimulants (Stempfle et al, 2021;Chojnacka et al, 2022). However, material recirculation, which is at the foundation of CE models, is not always feasible because of several technical and/or economic reasons (Donner and Radić, 2021).…”

“…The selected firm is in the Apulia region, which is the most important olive oil producing area in Italy, accounting for about 25% of olive-growing farms, 33% of olive groves, and 50% of olive oil production at the national level (data from the Agricultural Census ISTAT, 2011;ISMEA, 2021). Energetic valorization was elected as the circular pathway to focus on, since it is thematically dominant in scientific literature inquiring about the implementation of CE into the olive oil supply chain (Stempfle et al, 2021). Besides, energy crisis and independence from fossil fuels have become more and more relevant topics as also demonstrated by the recent geopolitical events (Russia-Ukraine crisis) that have highlighted the great vulnerability of the global energy supply chain due to the propagation of trade-related risks and price volatility, and the need to maintain this supply chain resilient using long-term approaches such as the recycling and circular strategy (Sun, 2022).…”

While the paradigm of circular economy (CE) and the processes of socio-technical transition have been broadly investigated at the theoretical level, understanding how the transition toward circular models can be implemented in practice is still limited. This contribution aims to provide in-depth and evidence-based insights on an emerging pathway for the operability of CE into the olive oil supply chain. A case study from the Apulia region (the leading olive oil producing area in Italy) is presented to show how an existing business model can be transformed into a circular one, and to what extent it can be replicated. The study focuses on a vertically integrated firm, in which a new industrial process has been introduced to manage olive pomace, which is one of the most important by-products obtained from olive oil extraction. The empirical analysis is built on the Circular Business Model Canvas (CBMC), which is conceived as a suitable theoretical and methodological tool to speed up the transition process toward CE at a micro-economic level. This analytical framework allows us to identify the interplaying elements that the firm combines to capture, create, and deliver value, as well as the relationships with the broader economic system. Particular attention is paid to two distinctive components of CBMC: material loops and adoption factors. Also, internal and external factors affecting the adoption of the new circular business model have been discussed by separating drivers and barriers of the transition process.

“…Therefore, analyzing all possible circular economic paths in the olive oil supply chain is essential. Stempfle et al ( 7 ) delineated these probable paths based on a thorough literature assessment. In this context, olive mill wastewater (OMWW) varies from 1.2 to 1.8 m 3 per tons of olives ( 8 ).…”

Valorizing the usage of olive leaves, bioactive compounds, biological activities, and food applications: A comprehensive review

et al. 2022

Olive oil production is a significant source of economic profit for Mediterranean nations, accounting for around 98 percent of global output. Olive oil usage has increased dramatically in recent years, owing to its organoleptic characteristics and rising knowledge of its health advantages. The culture of olive trees and the manufacture of industrial and table olive oil produces enormous volumes of solid waste and dark liquid effluents, involving olive leaves, pomace, and olive oil mill wastewaters. These by-products cause an economic issue for manufacturers and pose major environmental concerns. As a result, partial reuse, like other agronomical production wastes, is a goal to be achieved. Because these by-products are high in bioactive chemicals, which, if isolated, might denote components with significant added value for the food, cosmetic, and nutraceutical sectors, indeed, they include significant amounts of beneficial organic acids, carbohydrates, proteins, fibers, and phenolic materials, which are distributed differently between the various wastes depending on the olive oil production method and table olive agronomical techniques. However, the extraction and recovery of bioactive materials from chosen by-products is a significant problem of their reasonable value, and rigorous detection and quantification are required. The primary aims of this review in this context are to outline the vital bioactive chemicals in olive by-products, evaluate the main developments in extraction, purification, and identification, and study their uses in food packaging systems and safety problems.
