This new plant exploits the enormous potential of obtaining biogas from the organic matter contained in agricultural food waste, and will help the food industry to reduce the environmental impact caused by organic waste.
The plant, located at the AZTI-Tecnalia premises in Derio, aims to obtain biogas rich in methane by the process of anaerobic digestion* of the organic material contained in the sub-products from food, in order to transform it into electrical and heat energy.
In the same way, for 2010, the technological centre foresees adapting the plant and making a commitment to that renewable source of energy which has seen the greatest surge in recent years: hydrogen. So, the aim is to be able to obtain hydrogen and methane from the same combined fermentation process.
AZTI-Tecnalia specialists are thus researching the viability of obtaining benefit from a number of agricultural food sub-products, alone or in combination (co-digestion) with other elements from various sources, such as sludge from purifying plants or food waste from mass consumption. Amongst others are mixtures from animal husbandry silage (purines), together with waste from agricultural food industries (leftovers from fruit and vegetable markets, milk whey, fish ends, aquaculture waste, etc.
With the biogas plant it is possible to reduce the environmental impact caused by organic waste. The emissions of greenhouse effect gases into the atmosphere are reduced, smells are considerably reduced and the final value of the waste is enhanced, As a consequence, the industry can adapt itself to environmental and social requisites, at the same time as its processes are more efficient through making better use of available resources.
The plant is available to government bodies and to food enterprises and environmental services who are interested in developing R+D projects applied to the energy valuation of food sub-products, with the aim of obtaining information for decision-making in the installation of this kind of plant at an industrial scale.
AZTI-Tecnalia is supporting the food industry in sustainable development, implementing measures to enhance its environmental performance. The biogas plant complements the activities undertaken by the centre at its food processing pilot plant, in which valuation trials of sub-products as new sources of raw materials for transformed foodstuffs are also carried out. Likewise, more profitable and innovative options are being sought in order to manage subproducts and waste generated by the food industry and studies of the Life Cycle Analysis (LCA) of the products are undertaken, analysing where the main costs and environmental impacts lie, and proposing, in consequence, situations for the enhancement and optimisation of the process.
* Anaerobic digestion is a biological process which transforms organic material into biogas and into a digested sludge, which can be used as organic enhancement in agricultural applications. Biogas mainly consists of carbon dioxide and methane, the latter with a high calorific value and which, thereby, can be used as a renewable source of electrical and/or thermal energy, or as a fuel for vehicles.

An international team of researchers has discovered a new anti-cancer protein. The protein, called LHPP, prevents the uncontrolled proliferation of cancer cells in the liver. The researchers led by Prof. Michael N. Hall from the Biozentrum, University of Basel, report in “Nature” that LHPP can also serve as a biomarker for the diagnosis and prognosis of liver cancer.
The incidence of liver cancer, also known as hepatocellular carcinoma, is steadily increasing. In the last twenty years, the number of cases has almost doubled...
In just a few weeks from now, the Chinese space station Tiangong-1 will re-enter the Earth's atmosphere where it will to a large extent burn up. It is possible that some debris will reach the Earth's surface. Tiangong-1 is orbiting the Earth uncontrolled at a speed of approx. 29,000 km/h.Currently the prognosis relating to the time of impact currently lies within a window of several days. The scientists at Fraunhofer FHR have already been monitoring Tiangong-1 for a number of weeks with their TIRA system, one of the most powerful space observation radars in the world, with a view to supporting the German Space Situational Awareness Center and the ESA with their re-entry forecasts.
Following the loss of radio contact with Tiangong-1 in 2016 and due to the low orbital height, it is now inevitable that the Chinese space station will...

For the first time, an interdisciplinary team from the University of Basel has succeeded in integrating artificial organelles into the cells of live zebrafish embryos. This innovative approach using artificial organelles as cellular implants offers new potential in treating a range of diseases, as the authors report in an article published in Nature Communications.
In the cells of higher organisms, organelles such as the nucleus or mitochondria perform a range of complex functions necessary for life. In the networks of...
