BTB plant, pioneer in assessing construction and demolition waste


The plant Bizkaiko Txin-Txor Berziklategia (BTB), located in La Orkonera, Ortuella (Bizkaia, Basque Country) is the first plant of the Basque Autonomous Region dedicated to the assessment of waste derived from construction and demolition. Its set up, after an investment of 2,6 million euros, is going to prolong the average life of dumping sites.

The construction company Pavisa and the public corporation Garbiker, dependent on the Regional Council of Bizkaia, have designed the plant BTB for the treatment of construction waste, constituted basically by concrete, and domestic waste, sent to the garbigunes (centre of waste recovery).

The plant applies an adequate environmental treatment for this kind of waste and its subsequent re-utilisation. To do that, waste is first ground in a mill. The clean concrete is sieved and domestic waste goes to manual separation of wood, plastic and iron material. During the grinding and sieving process, iron remains are eliminated and fractions of different granulation are obtained. This material, once it is homologated, is ready for its re-utilisation. BTB has obtained the authorisation of the Basque Government to give added value to this kind of waste.

Less extractive activity

One of the benefits the new plant for the treatment of construction and demolition waste (CDW) produces is the diminution of extractive activities in Basque quarries, due to the substitution of those materials with recycled ones. CDW constitutes an environmental problem that must be solved to relieve dumping sites, eliminate dump, re-use primary materials and reduce deteriorating extractions for the environment.

The second stage of the Integral Plan of Urban Waste of Bizkaia establishes as objective to recycle 220,750 tons of CDW in 2007. In that scenario, CDW that mainly derives from minor works and home reparations takes a special relevance. This initiative of the Regional Council of Bizkaia has been materialised in the BTB plant. In relation to its design and machinery, it is one of the most innovative among this kind of installations in Spain.

The recycling of those materials allows a high level of exploitation of bricks, tiles, ceramics, concrete, wood, metals, paper and plastics. All that prolongs the useful life of dumping sites, as they are not used for this kind of materials. The recycling of the materials derived from construction and demolition waste provides some advantages, such as the lack of problems of storage or transport.

Treatment of 300,000 tons/year

The company Pavisa and the public corporation Garbiker share 50 % of the capital of Bizkaiko Txintxor Berziklategia (BTB). The plant is next to the controlled dumping site of inert waste dependent on Garbiker. It has been designed and mounted by Talleres ZB from Renteria (Gipuzkoa). The civil work has been done by Viuda de Sainz and the project has been developed by Idema. The whole output of BTB is 300,000 tons/year, with one working shift, distributed in 200,000 tons/year of treatment of specific material of concrete and 100,000 tons/year for the assessment of domestic and assimilable waste.

Im Focus: Researchers at Fraunhofer monitor re-entry of Chinese space station Tiangong-1

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...

Im Focus: Tiny implants for cells are functional in vivo

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...
