IBC container cleaning: The solution without a solvent.

Removes paint, adhesive and resin in an environmentally friendly way

Issue

IBC containers are standard containers commonly used in industry that need to undergo an elaborate and thorough cleaning process before being filled with highly sensitive substances such as car paint. The company uses a complex cleaning system in which the solvents used in the cleaning process are treated and disposed of in an environmentally friendly recycling process.

Challenge

Residues of paint, resin and adhesives are cleaned with volatile and flammable solvents according to generally accepted standards. However, use of these substances is associated with major risks and health risks for the company, the workforce and the environment. The requirements for handling these hazardous substances are extremely strict.

    Analysis

    The deposit build-up to be removed from the inside of the container consists of hardened paint residues, sometimes with several layers of residue on top of each other. They were removed in a semi-automated cleaning system using the solvent butyl acetate in a recycling procedure with brush cleaning. The resulting exhaust air was filtered off and solvent components were thoroughly removed by means of afterburning. Part of the butyl acetate used for cleaning was recovered by distillation and then disposed of.

    The cost drivers were unequivocally identified as the exhaust air systems and associated explosion protection measures. Thus, Caramba recommended switching to a water-based cleaning agent which has already achieved excellent results in the printing industry. The first laboratory tests were carried out at a temperature of 40°C. The same cleaning results were obtained on the dissolution system at 60°C using an aqueous solution of cleaning agent diluted 1:1, as with butyl acetate.

    Switching to Caramba Raster Clean as cleaning agent meant it was no longer necessary to use aromatic and aliphatic solvents for container cleaning. But this did not just result in a significant reduction in occupational health risks and environmental pollution. Changing to a water-based cleaning agent also yielded a 17.5% reduction in the annual cost of processing IBC containers.

„By developing a water-based product, we were able to achieve a tremendous cost saving of 17.5%, which mainly results from eliminating the thermal afterburner system and the explosion protection measures. Another key plus point is that there is no longer an unpleasant odour from the solvents. Thus, in terms of cost-effectiveness, occupational safety and environmental protection, the process we developed together is a realistic alternative to cleaning with solvents.“
