SULINGEN, Germany—H&S Anlagentechnik GmbH said it has delivered the world's first industrial-scale system to recover polyol from flexible polyurethane foam waste to a Polish slabstock maker.
H&S said the equipment went into operation recently. It is designed to yield 2,500 tons per year of recovered polyol.
Besides the recycling reactor, H&S has supplied the storage and conveying facilities for the solid and liquid input materials as well as cooling and storage tanks for recovered polyol.
The technology developed by H&S's chemists is based on acidolysis method. The process enables the foamer to take all of the flexible foam residues arising during foam block cutting and return it to the production process.
The recovered polyol can be replace up to 20 percent of virgin polyol in foam formulation without compromising the quality of the flexible foam product, H&S said.
