Global Platform for Sustainable Natural Rubber’s new policy framework, which was approved in the recently general assembly, will provide a clear framework for GPSNR company members to establish/ update supply chain commitments through their natural rubber purchasing policies.

It covers specifies key commitment details to no deforestation/conversion/degradation, upholding human rights, supply chain transparency and monitoring and reporting.

Members who joined GPSNR before the GPSNR General Assembly 2020 will be expected to have policies or other documents aligned with these requirements within 6 months after adoption by the General Assembly. Members who join after the GPSNR General Assembly 2020 will be expected to align with these policies within 6 months of joining GPSNR.

aModeled around the Platform’s 12 Principles of Sustainable Natural Rubber, the new policy framework sets out eight overarching themes that include commitments to legal compliance, community livelihoods, healthy, functioning ecosystems (including no deforestation), and respecting all human rights.

“This is a tremendous milestone for the Platform and for the natural rubber industry. In just under two years, GPSNR members developed and approved concrete policy commitments for companies to integrate into their sustainable natural rubber policies. Today, and despite the challenges we all faced during this global pandemic, GPSNR members send a signal to the world about their commitment to achieving a fair, equitable and environmentally sound future” said GPSNR Director Stefano Savi.

Around 85% of the world’s natural rubber is produced by smallholders. In order to transform a sector that is primarily reliant on smallholder producers, GPSNR is embracing smallholder inclusivity and a concept of shared responsibility through the establishment of a Shared Responsibility Working Group, which will identify how the responsibilities and costs of implementation can be equitably distributed across all stakeholder categories, with the understanding that smallholders should not carry the burden of a higher cost to implement sustainability activities in complying with the policy or implementation guidance to be developed.

“Smallholders are a crucial link in the natural rubber value chain, and they have a key role to play in driving awareness on-the-ground and setting the global agenda for sustainable natural rubber” remarked Director Savi.

This year, GPSNR welcomed 28 smallholder members from seven rubber-producing countries. These smallholders now constitute a newly approved standalone category and play an equal role in decision-making within GPSNR alongside the other four categories: producers, processors, and traders; tire manufacturers and other natural rubber makers/buyers; car manufacturers, other downstream users and financial institutions; and civil society.

GPSNR’s virtual General Assembly drew more than 120 attendees, including members of the Platform, partners and invited guests. In addition to voting on resolutions, GPSNR members also elected representatives to the 2020-2021 Executive Committee, which comprises representatives from each of the membership categories. And for the first time, three newly elected smallholder producers with diverse geographical backgrounds will participate in Executive Committee discussions and decision-making.

A new bio-based cut & chip resin for the most demanding applications.

NaugaShield BIO-TR 30 is SI Group’s latest advancement in bio-based performance resins designed to significantly improve cut and chip resistance in high-severity rubber applications. With approximately 75 percent bio-based content, this innovative material delivers on sustainability targets while exceeding the performance typically associated with petroleum-derived resins, making it a strong choice for applications such as OTR tyres in mining, construction and agriculture, mining conveyor belts, rubber tracks and mill linings.

Cut and chip resistance is a complex set of material behaviours, including static mechanical strength, dynamic response under deformation and ability to withstand sharp impacts and abrasive environments. In demanding applications such as mining or agriculture, materials must tolerate repeated high-strain loading and resist the initiation and propagation of tears. NaugaShield™ BIO-TR 30 was developed precisely to meet these conditions, demonstrating notably low dynamic heat buildup and excellent tear strength – characteristics closely tied to enhanced cut and chip resistance and long-term durability under cyclical loads.

To evaluate its performance, NaugaShield BIO-TR 30 was benchmarked in an Off-road Rib Tread formulation against two widely used industry references: a gum rosin/semi-aromatic C5/C9 resin combination and a styrenated DCPD resin. All materials were tested at an equal loading of 10 phr to provide a direct and unbiased comparison. Under these conditions, the bio-based resin consistently outperformed both alternatives, offering a stronger balance of reinforcing behaviour, improved tear propagation resistance and superior resistance to thermal degradation during dynamic flexing. Further improvements were achievable by reducing the amount of free extender oil in the compound, underscoring the resin’s adaptability in formulation design and its ability to unlock even greater performance when optimised.

These laboratory indicators were corroborated through extended Coesfeld Cut & Chip testing (see chart), in which compounds were subjected to up to 3,000 cycles at 200 rpm under a 200N applied force. Formulations containing NaugaShield BIO-TR 30 exhibited substantially lower mass loss and maintained tread surface integrity more effectively than the hydrocarbon and gum rosin-based-benchmarks. The performance advantage was even more pronounced in compounds adjusted for lower free oil content, confirming that the resin can be tailored to meet the durability requirements of the most challenging operating conditions.

The strong performance of NaugaShield BIO-TR 30 in OTR tread compounds can be readily transferred to other rubber goods that encounter similar wear mechanisms. Applications such as mining belts, agricultural and construction tracks or mill linings benefit from the resin’s ability to reinforce the rubber matrix, reduce crack growth under repeated impact and maintain structural cohesion under high-strain deformation. This versatility allows manufacturers to integrate a 75 percent bio-based resin that supports sustainability by reducing fossil-based content and helping end products last longer while maintaining – and often improving – operational performance across multiple product lines.

NaugaShield BIO-TR 30 is currently available in commercial quantities, enabling compounders and manufacturers to move directly from laboratory evaluation to pilot- and production-scale trials.
