A Multi-Functional Plant for Manufacturing Alternative Polyols in Dubai

Using in-house plants and their own waste production materials, companies can manufacture their own high-quality alternative polyols*) – in doing so, they cut costs.

German company Rampf Eco Solutions has worked with its collaboration partner Keil Anlagenbau to design a multi-functional plant for manufacturing polyols based on polyethylene terephthalate (PET), phthalic anhydride (PSA), and polyurethane (PU)/polyisocyanurates (PIR). It was delivered to a leading supplier of insulation technology in Dubai, erected on site, and put into operation. The facility now offers the option of manufacturing high-quality polyols from the customer’s own PU/PIR waste materials, the information says. Ester polyols based on PET or PSA could also be produced in the same plant.

As reported, the two companies are able to offer a complete solution for the international markets by combining their core areas of expertise:
■ “Rampf boasts comprehensive know-how in developing chemical solutions for manufacturing alternative polyols from PU and PET waste materials.
■ Keil Anlagenbau has extensive knowledge in developing and constructing tank farms and recycling, supply, dispensing, and process engineering plants.”

Expertise in the field of alternative polyols

According to Matthias Rampf, Managing Director of Rampf Eco Solutions, the company’s research teams have been developing high-quality alternative polyols for over 20 years. In two of the largest multi-functional plants in Europe at the corporate headquarters in Pirmasens, Germany, tailored ether and ester polyols were manufactured from industrial and post-consumer PU waste materials (from flexible to rigid foams) as well as PET/PSA.

As reported, the company has also developed a chemical process that makes it possible to use PET/PSA, other polyesters such as polylactide (PLA), polycarbonate (PC), and polyhydroxy butyric acid (PHB), and renewable or bio-based raw materials such as vegetable oils as sources of raw materials for manufacturing alternative polyols.

*) A polyol is an organic compound containing multiple hydroxyl groups. According to Wikipedia, a molecule with more than two hydroxyl groups is a polyol. Low molecular weight polyols are widely used in polymer chemistry, where they function as crosslinking agents.
