Since the beginning of its activities, AMBISAT has been actively engaged with the environment and with technological innovation, regularly participating in national and international tenders for R&D&i projects that can be applied to environmental management.

AMBISAT projects have been developed to solve existing environmental problems, to ensure the rational use of renewable energy sources and thereby effectively reduce the effects of CO2 emissions into the atmosphere.

The two patents designed by AMBISAT Ingeniería Ambiental are:

“Using sludge from treatment plants for construction purposes related to road safety and acoustic shielding”, dated 27 December 1999 (published in the Industrial Property Bulletin on 16 February 2000 under number 2130086B1 and P 9702062)

Its purpose is to study the use of sludge from Urban Waste Water Treatment Plants for the construction of low resistance elements in public works, such as road safety elements and acoustic shields, or sub-foundations reinforced with steel on public streets and other practical uses.

This initiative would provide an easy, swift and local use for sludge from treatment plants that is currently a waste product that has to be eliminated. The use of these products as construction components contributes to minimize their transport to landfills and offers an alternative to the use as fertilizers when the presence of certain substances such as heavy metals, makes them unsuitable for agricultural purposes. However, mixing sludge, cement and lime strengths the final product for use in public construction projects.

The parts obtained are low density, porous with a high acoustic absorption capacity and easily moulded as they enjoy similar characteristics to concrete, which opens a wide spectrum of use in public works (acoustic shields, road sub-foundations...).

“Device for the Mechanical Exploitation of Marine Wave Energy aimed at improving Effluent Dispersion in Submarine Outfalls”

The main object of this project is the design and construction of a prototype device that allows the use of the mechanical energy of waves to drive sea water through a submarine outfall.

The use of renewable and free energy saves money, a fact that can be taken into account in the daily operations of desalination plants or Urban Waste Water Treatment Plants. It is possible to quantify the economic and energy savings made from harnessing renewable and free energy, such as waves.

This device would provide savings in the daily operations of desalination and treatment plants. The reason is that desalination and water treatment plants use effluent flow pumps that consume a large amount of electricity. Although there are a number of solutions that can be used to minimize these costs (maximum use of gravity, discharge during low energy cost periods requiring prior accumulation...), the costs will ultimately affect the energy and economic balance sheet of these facilities, apart from not contributing to Kyoto emission reduction commitments.

In order to quantify the problem, the economic and energy savings that come from harnessing renewable and free energy, such as waves, at a pumping station with two 45 kW pumps that alternately operate at full capacity, generating a flow of 400 m3/h to a distance of one mile would be about 30,000 euros a year. In terms of meeting the Kyoto Protocol, we would be talking about reducing CO2 emissions by 500 tons a year. Among the activities developed by AMBISAT, our R&D&i activities are considered strategic objectives. For further information, please click here.
