Sustainable biorubbers to substitute common TPEs.

RUBRAN®

B4Plastics’ RubberPlastics products, brought to you as RUBRAN®, aim to realize material properties akin to rubber or thermoplastic elastomers while still offering sustainability both at the raw materials side, including a recycled postconsumer plastic waste component and bio-based content, and at its end-of-life.

The challenge

Traditional thermoplastic elastomers (TPEs) are dependant on fossil-based resources. These materials are responsible for the accumulation of plastic waste because of their linear design, which is hindering the circularity. Around 4% of the global CO2 emissions and 40% of the plastics in packaging are due to these conventional elastomers.

The methods

With RUBRAN®, B4Plastics wants to revolutionize the elastomeric polymers field. We not only use bio-based building blocks, created from nature, but also incorporate post-consumer plastics waste, that would otherwise be incinerated or landfilled. Furthermore, it is our ambition to offer full circularity through our materials by closed-loop recyclability. The properties of our material are completely tunable to the end applications.

The result

Combined with the upcycling of post-consumer plastic waste, shorter transportation distances, and closed-loop recycling potential, RUBRAN®is forcasting a significant climate impact reduction potential of 1000 tonnes of climate-threatening CO2 equivalent emissions annually, based on a 500 tonnes/year production. Compared to conventional elastomeric polymers, this means a reduction of around 40% CO2

This amount is equal to driving a car around the world for 126 times, the annual emissions of electricity consumption of 429 EU households or the production of 2.5 million running shoe soles, which would be enough to provide every recreational runner in Belgium within one year. This approved climate impact forecast is third-party validated through a programme by the European Innovation Council and Climate-KIC.

The perfect sustainable biorubber for elastomeric applications.

Think high friction. noise dampening. bounce resilience. inflation. less microplastics. less CO2 impact.

Shoe soles

More than 5 billion people wear out their shoe soles every day between sunrise and sunset. Trillions of microplastics are released in that way. Time for RubberPlastics soles!

Forklift tyre

Our logistic systems exhaust a lot of CO2 because of fossil energy sources used. But what if we could make the tyres of our transportation systems such as forklifts, from RubberPlastics? Less energy and less microplastics!

Bike handgrips

You can sprint on the Champs Elysees to become an eternal winner. You can also enjoy RubberPlastics handgrips on your bike: the most guaranteed way to become an eternal sustainability winner.

Hoses & cables

You touch it mostly in the morning and in the evening: the charge cable of your smartphone. It feeds the power to your most intimate device during the day. Why not enclose the power to your smartphone in noble RubberPlastics? That’s what we call “experience eco-luxury” every single day.

RUBRAN®, together with the other B4Plastics' materials, is awarded Cleantech Materials Hero!

We cannot image a world without textiles, fishing nets, carpets, fibres in car tyres, ropes, and sportswear. Nevertheless, these materials are a major source of pollution. When used, these products release microplastics that are very harmful to the environment. Our efforts were rewarded by the Cleantech jury by choosing B4Plastics as true Cleantech Materials Hero 2022.

RUBRAN® is the first product of our RubberPlastics technology.

RubberPlastics are our elastomeric materials to help our New Plastics Economy land softly. The dampening properties of these materials go hand-in-hand with biobased or recycled raw materials, to give the best circularity of rubbery materials in the world.

Ready to challenge the future, together?

We are constantly looking for new challenges to redefine the composition of plastic and aiming for a sustainable future. Together, B4Plastics is on a mission.
