Catalytic hydrogenation depolymerization: BASFRecent Research Landscape

Inefficient separation of aromatic amines during polyurethane depolymerization leads to low purity and high waste. This process engineers the chemical recovery of PMDA specifically as an HCl salt to ensure high-yield isolation from rigid foam waste streams.

What technical problems is BASF addressing in Catalytic hydrogenation depolymerization?

Inseparable multi-material polymer waste

(35)evidences

Variations in solid waste materials and melt streams lead to non-uniform output. Standardizing the processing of diverse polymer inputs ensures predictable target product specifications.

Mixed polymer waste contamination

(12)evidences

The thermal requirements for breaking polymer bonds lead to excessive operational expenses. Heat integration addresses the thermodynamic inefficiency inherent in large-scale chemical recycling.
