HF MIXING GROUP´s latest developments significantly improve the sustainability of the tyre manufacturing industry. The company has already launched several new solutions and is working on many projects to be launched soon. 

With a long history and strengths in the construction of machines, engineering of mixing room controls and automation, as well as complete solutions for the rubber processing industries, the HF MIXING GROUP is able to develop, deliver and optimise the customised mixing room to reach productivity, quality, sustainability and safety goals. 

The intelligent controllers – iXSeal and iRam – are software-based and both are included within the HF MIXING GROUP´s ADVISE automation system solution. Several customers already benefit from HF´s software with minimised wear, less cleaning effort, improved mixing quality, lower oil consumption and, therefore, less recycling effort and costs.

The latest machine developments, namely the newest surface treatment technologies and the maintenance box (mBox), deliver a more sustainable approach and safety concept with financial benefits by reduced maintenance effort and a longer machine lifetime. HF MIXING GROUP shows that sustainability and safety can be achieved simultaneously with better quality and increased productivity.

The partnership between HF MIXING GROUP and WF Recycle-Tech enables a revolutionary new pyrolysis solution, improving the recycling of end-of-life tyres (ELTs) to the tyre manufacturing industry. The patented, proven and tested system is designed to process the rubber into its base compounds: TDO (tyre derived oil), syngas and raw recovered carbon black (rCB). For example, 1.5 tonnes of rubber crumb derived from passenger car tyres produce a mass balance return of 50 percent TDO, 40 percent rCB and 10 percent syngas. All in all, the unique patented 2-stage process recovers carbon black and tyre-derived oil with excellent material properties.

HF MIXING GROUP is excited to announce further solutions within 2022 and is looking forward to fruitful conversations during the upcoming events in Germany, US and Asia. Reduce the energy consumption and optimise the footprint.

The Global Platform for Sustainable Natural Rubber (GPSNR) has introduced its new Assurance System, a significant milestone in advancing sustainability across the natural rubber supply chain. Developed through extensive collaboration among GPSNR's Singapore-based members – including smallholders, producers, traders, tyre makers, automakers and NGOs – the system aims to tackle critical issues like deforestation, biodiversity decline, labour rights violations and human rights concerns.

The framework enables companies to align with GPSNR’s sustainability standards, evaluate supply chain risks, undergo independent verification and disclose progress transparently. A key innovation is its risk-based approach, which adjusts oversight based on the severity of environmental or social risks in specific regions or operations, optimising resource allocation. GPSNR also provides tailored tools and guidance to help members implement the system effectively, fostering accountability and improved practices industry-wide.

Stefano Savi, CEO, GPSNR, said, “This is more than a milestone for GPSNR. It is a pivotal moment for the entire natural rubber industry. With our organisational design finalised and both Shared Investment and Risk-Based Assurance in place, we’re ready to move into implementation. I look forward to the impact this will have on smallholder livelihoods, the environment and supply chain resilience.”
