Lubrizol has a biomass balance TPU series, ESTANE RNW TPU. Four commercial grades were launched in 2024 (read the press release here), and is open to the discuss the development and introduction of selected additional grades.

The mass balance concept allows the chemical industry to gradually replace fossil based raw materials with recycled and/or bio-based ones. It is a chain of custody model used to track the total amount of sustainable raw material content (tracking through the manufacturing process/supply chain while ensuring an appropriate allocation of this content to the finished product). Rather than using virgin fossil feedstocks, the sources of sustainable feedstocks include:

Biomass – made using bio-based raw materials => Biomaterial
Recycled polymers – made using post-use => Circular Materials
And Biowaste – made using various sources of biowaste materials => Bio-circular materials.

The principle is simple. The amount of incoming sustainable materials is balanced with the amount of outgoing finished sustainable goods and are closely tracked. All mass balance attributed products that Lubrizol offers are certified under the ISCC PLUS certification scheme. This ensures full traceability of the supply chain for the sustainable raw materials.
