Sumitomo Rubber said it has now developed reduced odour natural rubber that emits ‘significant’ less odour.

The company , with its proprietary raw material processing technique, achieves a significant reduction in odour by suppressing the breakdown of odour-causing non-rubber components (such as proteins and lipids) that are found within natural rubber in its raw material state.

“We believe that the establishment of this new technique represents a major step toward solving longstanding odour issues not just at natural rubber processing plants, but also at tyre factories and other sites where natural rubber is handled,” said Sumitomo Rubber.

 

Specialty material solutions provider Trinseo has announced that it has established a tool that provides cradle-to-gate Product Carbon Footprint (PCF) and Life Cycle Assessment (LCA) data.

The tool features nearly 6,000 Trinseo products, which can be accessed by customers to know the exact carbon footprint associated with a particular product.

On the other hand, LCA assess the environmental impacts of a product beyond PCF, including the use of resource, human health, ecological impacts, and more. This data the company said is crucial for understanding the environmental impact of products, allowing effective material comparison, enhancing R&D innovations, and ultimately contributing to a customer’s sustainability goals.

The Trinseo’s PCF and LCA tool follow the TfS guidelines and the latest European Product Environmental Footprint (PEF) methodology and are compliant with the GHG Protocol and ISO standards 14040, 14044, and 14067.
