“…Shredded pruning residues likewise offer an opportunity to improve soil functioning as tangible water and soil conservation measure, also reducing erosion and preserving soil moisture. This agricultural operation allows to reduce the appearance of weeds and thus the application of herbicides, as well as contributes to the improvement in fertility and C sequestration (Gómez-Muñoz et al, 2016;Taguas et al, 2021). The other application that takes part in the reduction of chemical fertilizer use is the spreading of two-stage pomace from olive oil extraction.…”

This work aims to present a methodological proposal based on Life Cycle (LC) methodologies, and circularity performance indicators, to assess closed-loop pathways by providing comprehensive results on economic and environmental impacts generated by agri-food production systems. The methodological approach will be tested on olive oil production systems, one of the most important agri-food chains for Mediterranean countries, whose import and export significance is set to grow in light of the shrinking market supply of seed oils. Some insights for the co-products valorization are provided through the evaluation of the reuse of by-products as a possible resource capable to improve the sustainability of the olive oil farms. The integrated application of three different methodologies, Life Cycle Assessment (LCA), Environmental Life Cycle Costing (ELCC) and Material Circularity Indicator (MCI), enabled comparative evaluation of Extra Virgin Olive Oil (EVOO) production under a linear production model with production under a circular model. The circular scenario was better in most environmental impact categories, registering an improvement in Global Warming Potential (GWP) of nearly 30%. In economic terms, there was a lower production cost for the circular scenario and a lower environmental cost by reducing the use of synthetic products through the reuse of waste products. The circular scenario recorded a higher degree of circularity due to a reduction in virgin raw materials used in the production process and a reduction in non-recoverable waste. The implementation of circular strategies represents one of the possible trajectories to guide the ecological transition, and the proposed methodological framework can support the decisions of both producers and public decision-makers toward more sustainable and efficient production patterns.

“…Currently, the olive cultivation systems for the oil supply chain divides into traditional and modern. The density in traditional systems does not exceed 200 trees/ha, while in modern ones, it can reach up to 2000 trees/ha [56]. A further difference is that traditional olive groves are on marginal lands or in the edges of lands intended for other crops.…”

“…A further difference is that traditional olive groves are on marginal lands or in the edges of lands intended for other crops. In contrast, modern systems are dedicated plantations, equipped with irrigation systems, and designed to mechanize harvesting, pruning, and residual biomass collection [35][36][37]40,[55][56][57]. The usual classification considers high density (HD) and super high density (SHD) systems.…”

“…One of these [60] examines a new type of intensive olive grove called pedestrian orchards, proposed as an alternative to current HD and SHD systems since it could further reduce production costs and enhance the quality, functional properties, and typicality of the oil produced, simultaneously reducing environmental impact. The other [56] examines the problem of mulching with lignocellulosic material (leaves and pruning) resulting from the maintenance of modern SHD plants. The experimentation activity implies high costs and long times for both these aspects.…”

Evolution of the Olive Oil Industry along the Entire Production Chain and Related Waste Management

The production of olive oil involves the sustainable management of the waste produced along the entire production chain. This review examines the developments regarding cultivation techniques, production technologies, and waste management, highlighting the goals to be achieved and the most reasonable prospects. The results show that cultivation and production technology have evolved to an almost final solution to meet economic feasibility, keeping the oil’s high quality. Continuous horizontal decanters will coexist with traditional mills in many countries with old olive oil production and consumption traditions. High-quality products have conquered markets, especially in the wealthiest countries. At the same time, the exploitation of dried pomace by solvent extraction is increasingly an obsolete practice. However, waste management is still looking for one or a few reasonable solutions that meet modern society’s constraints. The enhancement of some experienced technologies and the full-scale application of emerging technologies and strategies should solve this problem in the short–medium term. A short discussion is reported on the possibility of unifying the nature and the quality of the waste, whatever the olive oil production method is. Furthermore, modern thermochemical treatment for solid wet organic waste disposal is examined and discussed.
