Specifications

Sorba0006

BABS consists of cellulose. It is produced from the spongy tissue of maize straw. The key specifications of BABS are:

  • Water absorption and retention capacity is 25-35x its own weight (similar to the Super Absorbent Polymers SAP)
  • Density: 25 – 50 kg/m3 (similar to EPS)
  • Reactive inner surface is extremely high (similar to activated carbon)
  • 100 % renewable, acid-proof and biologically stable for more than 12 months (depending on the environment)
  • In a composting process 100 % biodegradable in the medium term.

The preparation of BABS is specifically tailored to suit its various applications.

Application as plant substrate suppl.

IMAG1053[1] (Mobile)Application as a plant substrate supplement

Ricoter, a commercial substrate manufacturer in Switzerland, uses BABS as a supplement to several plant substrates. One blend is currently marketed by the supermarket chain Coop under the name “Premium substrate with biological water absorbent.

A BABS supplement of 3-5%, results in substantial quality improvements of the plant substrate:

  • increased capacity for water absorption and retention
  • extended irrigation intervals
    • higher total substrate volume at lower density

BABS is certified for organic production.

Application air filters

BABS is the basis of our radically new filter that retains ammonia (NH3), odour and dust from the exhaust air of animal production halls (poultry and pig production). In this application, BABS is impregnated with an acid that reacts with ammonia to form a stable salt. The proven ammonia removal efficiency is >95%.

The advantages of the BABS-filter versus today’s state of the art solutions for air purification include savings in capital and operating cost, as well as higher operating safety. We expect overall cost reductions of 20-30%.

The BABS-filter has been developed and tested in cooperation with the University of Fribourg (Switzerland). The first commercial scale units will be installed in 2016. BABS-filters will be sold via professional suppliers of ventilation solutions for animal halls.
