• Density: 15-30 kg / m3, comparable to expanded polystyrene (EPS)
  • Water absorption capacity: 20 to 40 times its own weight, so well comparable to Superabsorbent Polymers SAP
  • Very porous, with an extremely high internal surface, which is comparable to activated carbon
  • Acid-resistant, medium resistance to pressure

BABS filter material

BABS, after impregnation with acid, is an excellent absorbent of ammonia, e.g. from the exhaust air of animal halls or from microbial degradation processes. The ammonia is captured in the form of ammonium sulfate on BABS and can be used as a solid fertilizer. This CORMO absorption process is technically easy to implement, a significantly cheaper investment and simpler to operate than conventional acid scrubbers.

The method was developed by CORMO in collaboration with the University of Applied Sciences Freiburg and is ready for implementation. CORMO has the planning and operational know-how.

The exhaust air of animal halls, composting plants, slaughterhouses and the like contain high concentrations of ammonia and odors. Ammonia is a large-scale environmental pollutant and odor pollution is increasingly causing problems with the neighborhood.

CORMO, in collaboration with the University of Applied Sciences Friborg, has developed a process for the acid impregnation of BABS and for the treatment of this exhaust air. The process is simple and inexpensive to buy and reliable in effect.

BABS Fine Granulate

BABS is the best natural absorbent on the market due to its enormous water absorption capacity. This property can be used particularly well in various applications: BABS is now used as a component of substrate mixtures, increasing their water absorption capacity and extending the irrigation intervals.

Another application is in the coverage of plant substrates in greenhouses. Today, this function is often provided by Vermiculite. The use of BABS fine granulate protects the seedling and the substrate in the best way against direct sunlight, dehydration and crusting. BABS is compressed for this application. As a result, the storage and transport volume are reduced, and it can also be deployed easily and dust-free using spreaders.

BABS spreading granulate can also be used as an absorbent for oil, grease and chemicals.

Compressed BABS spreading granulate as a casing for plant substrates – protection of direct solar irradiation, dehydration and crusting.

BABS for Sprout Production

Bound and sterilised BABS as a substrate for the production of sprouts – less effort, better quality!

For the production of sprouts, a substrate is needed that is sterile, can absorb a lot of water, and allows oxygen transfer to the roots. BABS can do it all!

Sprouts of wheat, alfalfa, soy, sunflowers and many other plants are tasty and refreshing and therefore enjoy increasing popularity. In the download, Philip Pfleger explains the various health benefits of sprouts and everything else that makes sprouts so interesting!

BABS as a Component of Insulating Plaster

Facades must be renovated from time to time. The integration of a thermal insulation would be desirable, but is often not possible due to cost reasons. The use of BABS as a component of the facade plaster can be the ideal solution here, especially in older buildings. The porous structure of BABS provides excellent insulation properties.

CORMO, under the leadership of a globally active industrial partner, has prepared the BABS foam so that it can be sprayed onto the building facades as a mixture with a mineral mortar using conventional spraying equipment. The cost of this insulation effect is significantly lower compared to thermal insulation systems applying insulation boards.

BABS as Bonded Moldings

CORMO has found a way to make loose BABS granules into bonded packaging pieces and boards that are similar to Styrofoam, yet renewable and fully biodegradable. Unlike insulating materials made of natural fibers, the pieces and boards are resistant to pressure – even at a lower density. They can be produced using the known thermobonding process, in different densities and thicknesses.

The worldwide market for EPS sheets made of Styrofoam is enormous and is also growing rapidly. The opportunity for CORMO and its partners is to identify and conquer applications in markets where the specific advantages of BABS can be fully realised.
