Olive Mill wastewater bioremediation towards detoxification

Paixão, Susana M.; Ribeiro, Belina; Sàágua, M. C.; Baeta-Hall, Lina; Correia, Anabela; Duarte, José Cardoso

Olive oil production is a traditional agricultural industry in Mediterranean countries and Portugal is one of the ten major producers. This industry generates an effluent, olive mill wastewater (OMW), which does not undergo any treatment and, usually, is stored in evaporation lagoons or spread on the land. Disposal of olive oil mill wastewaters is a serious environmental problem due to its high organic loading,...

Oleico+ project : olive mill wastes and the sustainability of the olive oil ind...

Duarte, José Cardoso; Santori, Francesca; Ribeiro, Belina; Augusto, Gabriela

Every 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 (...

New technologies for municipal wastewater treatment

Ribeiro, Belina; Moreira, Cristina; Pontes, Diogo; Grasmick, Alain; Duarte, José Cardoso

New technologies to treat and recycle water from municipal waste water treatment plants are of utmost urgency. This study is taking place on the Mondego River, lower basin and estuary, from Coimbra to Figueira da Foz and contribute for the environmental sustainability of this region. In this work we developed a new treatment system using submerged membrane bioreactors for improved treatment and removal of pollu...

Oleico+ sustainability in the olive mill waste management

Ribeiro, Belina; Duarte, José Cardoso; Santori, Francesca; Auguto, Grabriela

Olive 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 ...

Ethanol production from enzymatically pretreated wheat straw

Duarte, José Cardoso; Pereira, Joana; Paixão, Susana M.; Baeta-Hall, Lina; Ribeiro, Belina; Sàágua, M. C

Lignocellulosic biomass can be utilized to produce ethanol, a promising alternative energy source for the limited crude oil. Wheat straw is an abundant agricultural residue which can be used as lignocellulosic raw material for bioconversion. There are mainly two processes involved in the bioconversion: hydrolysis of cellulose in the lignocellulosic biomass to produce reducing sugars, and fermentation of the sug...

Bioethanol production from agricultural wastes

Duarte, José Cardoso; Sàágua, M. C.; Baeta-Hall, Lina; Correia, Anabela; Ribeiro, Belina; Lourenço, V.; Pereira, J.; Paixão, Susana M.

In this study, different strains of Saccharomyces cerevisiae have been screened for the ability of bioethanol production. Yeasts were grown in synthetic liquid medium containing two different substrates: sucrose at different concentrations (10 to 400g/l) and cane molasses (120g/l of sucrose). The screening was made in batch regime and the growth rates, ethanol and biomass productions were determined. The result...

Treatment and reutilization of effluents: one Mediterranean project

Duarte, José Cardoso; Mateus, Marta; Eusébio, Ana; Almeida-Vara, Elsa; Ribeiro, Belina; Baeta-Hall, Lina; Hassani, Lahcen; Nejmeddine, Ahmed

The problematic of effluent treatment from olive oil industry as been the subject of an European Commission funded project (INCO-MED programme): “Mediterranean Usage of Biotechnological Treated effluent Water”. The potential that effluent offers to increase the availability of water, in mediterranean regions, was the final goal of the project, co-ordinated by INETI with partners from EU and MPC. In the project ...
