- Oleico+ project : olive mill wastes and the sustainability of the olive oil industry in EuropePublication . Duarte, José Cardoso; Santori, Francesca; Ribeiro, Belina; Augusto, GabrielaEvery year more than 15 millions tones of olive mill wastes (OMW) are generated in the EU. Those wastes consist in vegetation waters, effluents from olive oil, washing, leaves and other solids coming from wet pomaces from two phase extraction systems. Each of these residues presents different challenges, and is sometimes covered by different legal frameworks at European and National level. The Oleico+ project (LIFE07INF/IT/438), brought together four European Institutions from olive oil producing Countries, Greece, Italy, Spain and Portugal, to seek and select a set of environmental friendly technologies for the remediation or valorization of OMW, and to raise the awareness of olive oil stakeholders for an environmental sustainable olive mill waste management. The OMW management is becoming a critical issue for the sustainability of olive oil industry, because of the increasing quantities generated, the public environmental awareness and stricter environmental laws. Challenges posed by the OMW management are as diverse as the context of olive production itself. In all cases olive mill owners are in the top of an economic sector of major social and environmental importance in some of the more vulnerable Mediterranean regions of Europe, in an environment of depressed olive oil prices and a several of legal constrains and regulations. In this paper we examine the different contexts of OMW generation and management, their respective waste-streams and legislative frameworks. The work will also compare the situation across the four Member States, and presents the different technologies selected for the “Awareness Raising Campaign for the Treatment and Valorization of Olive Mill Wastes” now occurring in all Member Stat
- Oleico+ sustainability in the olive mill waste managementPublication . Ribeiro, Belina; Duarte, José Cardoso; Santori, Francesca; Auguto, GrabrielaOlive oil production generates olive mill wastes estimated at 2.5 million tonnes. More than 80% of olive mill wastes consist in water. Olive mill wastewater (OMW) has environmental impacts due to its high organic load and contents in phenols, lipids and organic acids. The project Oleico +, supported by the European Program LIFE, brought together 4 Institutions from 4 European Member States to seek and select a set of environmental friendly technologies for the remediation or valorization of olive mill wastes, and to raise the awareness of olive oil stakeholders for an environmental sustainable olive mill waste management. The OLEICO + project selected eight technologies to manage olive mill wastes that may be applied to different olive mill systems and amounts of waste generated. This selection was performed with a point to grid classification of technologies sustainability and status. To access eco-sustainability several parameters were accounted, including carbon dioxide emissions, landscape impacts and bead smells. Eleven technologies were selected out of 28 inventoried. Specifically five of these technologies deal with OMW and its detoxification, and four of them produce reusable water for irrigation. Other three technologies are focused in the energetic and or agronomic valorization of olive mill wastes. Some of these technologies present positive net income values, a many of them do not require specialized workforce, but the small dimension of olive mills make the management of olive mill wastes a challenge for the industry
