The novelty of the system lies in the possibility of having an on-site installation at the farm itself, thus avoiding the transport of the purines to other, off-site plants for their treatment.
ADE Biotec has undertaken the treatment of these residues in locations in Gipuzkoa, other areas of the Basque Country and a patented technology. In the case in hand, the purine treatment plant is installed on a pig farm at Egiluze in Renteria (Gipuzkoa).
Nowadays, the purines (excrement mixed with waste water from the farm) represent one of the most serious problems in agriculture, both from an environmental perspective (massive use thereof produces contamination of the water table and land) as well as for, an economic point of view (waste management demands much time and effort).
In this way, more than 80% of the oxygen consumed by the compounds that oxidise in the water – phosphorous and nitrogen – can be removed from the purines.
Other advantages of this technique are its low cost, the fact that there is no need for chemical reagents an there is no limitation of scale and its easy automation.

At the 2018 ILA Berlin Air Show from April 25–29, the Fraunhofer Institute for Laser Technology ILT is showcasing extreme high-speed Laser Material Deposition (EHLA): A video documents how for metal components that are highly loaded, EHLA has already proved itself as an alternative to hard chrome plating, which is now allowed only under special conditions.
When the EU restricted the use of hexavalent chromium compounds to special applications requiring authorization, the move prompted a rethink in the surface...
At the ILA Berlin, hall 4, booth 202, Fraunhofer FHR will present two radar sensors for navigation support of drones. The sensors are valuable components in the implementation of autonomous flying drones: they function as obstacle detectors to prevent collisions. Radar sensors also operate reliably in restricted visibility, e.g. in foggy or dusty conditions. Due to their ability to measure distances with high precision, the radar sensors can also be used as altimeters when other sources of information such as barometers or GPS are not available or cannot operate optimally.
Drones play an increasingly important role in the area of logistics and services. Well-known logistic companies place great hope in these compact, aerial...
