ODS Abatement, fridge & freezer recycling, recovery of CFC & Pentane from foam and insulation material

LESNI's combined CFC and VOC recovery plant provides the ultimate integrated solution for purifcation of ozone depleting substances. The package generally consists of several purification steps upstream of a selective catalytic abator with a tail end chemical scrubber in a compact, but favourable and economical approach to onsite recovery.

The solution offers a complete purification of all emissions generated by the recycling process thus reducing waste, disposal and operating costs. This proven and developed technology has been successfully in operation across Europe as soon as the US. The mixture of organic and non-organic gases, formed during the mechanical pulverisation and recovery of blowing agent from the insulation material in fridge and freezers are completely purified to EU directive for VOC.


Air Purification

Air Purification is the final step in the sterilization process, and without a doubt it’s the most important step, due to the potential risk associated with flammability and toxic nature of the ethylene oxide. LESNI solution focuses on the safety, performance, and reliability of the purification system to handle variable and peak concentrations of ethylene oxide from the process various stages.

The LESNI Catalytic Abatement Plant (CAP) is installed to purify exhaust air from production facilities or processes contaminated with organic compounds, which does not contain any components that can poison the catalyst. The organic pollutants are converted into CO2 and H2O on condition that all pollutants are compounds containing only carbon, hydrogen, nitrogen and oxygen. 

The plant supersedes US emission limit legislations demanding better than 99 % purification or less than 1 ppm, as well as meeting current European standards of 0.5 mg/Nm³ (TA-Luft).
