The Global Platform for Sustainable Natural Rubber (GPSNR), representing nearly 60 percent of the industry’s value chain, has established a standardised assurance system. This system, which was agreed upon at a recent Extraordinary General Assembly, offers a step-by-step process for companies to implement and verify sustainable practices.

The assurance system is undergoing pilot testing with volunteer manufacturers and processors until August 2024. Simultaneously, three of the four mandatory elements are open for public consultation to gather feedback and refine the model. This feedback and insights from the pilots will be incorporated into the assurance model before being presented to members for review at the Annual General Assembly in October 2024. By 2025, all GPSNR members will be expected to utilise this standardised system.

“ Having a system that can verify and cross check the implementation of our members’ commitments has always been our overarching goal at GPSNR. With the voting in of the Assurance Model structure, our members have demonstrated their intent to deliver on their sustainability promises. I am especially proud of the multistakeholder nature with which the assurance model has been agreed upon, keeping in mind the practical position of each member category,” said Stefano Savi, GPSNR’s Platform Director. 

The core of the model comprises four mandatory elements:

• Assurance Assessment Checklist: This checklist outlines companies’ minimum requirements across all aspects of the GPSNR’s policy framework.
• Assurance Protocol: This protocol provides guidelines for external assessors evaluating companies’ adherence to the standards.
• Remediation Protocol: This protocol lays out actions and timelines for addressing any gaps identified by the assessors.
• Members’ Journey: This broad timeline outlines the steps companies must take to comply with the requirements.
•  

Furthermore, the model includes supplementary tools to support member implementation, such as a due diligence framework and national risk assessments.

GPSNR members will convene next week in Singapore to finalise the details within the Assurance Model checklist, including the minimum requirements, permissible claims based on compliance, pilot feedback analysis, and the protocol for third-party assessors.

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.

Longxing Chemical Stock has announced plans to acquire 100 percent of China Rubber (Chongqing) Carbon Black from CSRC (Singapore), according to a filing with the Shenzhen Stock Exchange.

The target company is a key producer of carbon black, a vital material used in the manufacture of automobile tyres and other rubber products.

Longxing Chemical initially proposed purchasing a 55 percent stake in the company, with its actual controller, Liu Jiangshan, set to acquire the remaining 45 percent. However, the plan has been revised, and Liu Jiangshan will no longer participate in the acquisition.

The updated proposal is still in the planning stage, with specific terms and conditions yet to be finalised. Further details are expected as the process progresses.

PPG has formally announced the completion of the sale transaction of its silicas products business for USD 310 million (approximately) in pre-tax proceeds to Qemetica, a leading manufacturer of soda ash, silicates and other speciality chemicals.

Tim Knavish, Chairman and CEO, PPG, said, “We are pleased to complete this transaction with Qemetica, and I want to thank the silicas products business employees for their dedication and commitment to the business and to PPG customers throughout the years.”

Kraton Corporation, a leading global sustainable producer of speciality polymers and high-value bio-based products derived from pine wood pulping co-products, has increased the price of its SIS polymer products by USD 330 per MT.

The company said the price hike was due to continued increase in raw materials and process chemicals.

The price hike will be global and comes into effect from 1 January 2025.
