CirBind - Circular binder applications

How to generate safe, strong, and high impact circular binder applications? This scale-up of the Plantics-GX bioresin production process for an industrial environment.

In short:

There is a growing market for safe bio-based and bio-degradable industrial (polymer) products
We need to scale up on the GX bio-resin production
This can possibly save up to 80%-90% on CO₂ emissions

Scaling up: a challenge

Many construction materials such as wood panels contain toxic binders. These binders are persistant pollutants and carcinogenic as they are made of the hazardous formaldehyde-based polymer resins. There is a strong growing market demand for these safe bio-based and bio-degradable industrial (polymer) products, as there is no bio-based thermoset binder available on the market today.

An invention of the University of Amsterdam (UvA) is a polymer called Plantics-GX or simply GX. This is a polymer resin that is safe to use. It is 100% bio-based, recyclable, and if it enters in the environment it is bio-degradable. Moreover, it is a strong material and has very good binding properties. The spin-off company Plantics B.V. aims to further develop the production process, commercialize this invention and develop applications together with strong (market) partners. The monomers that are used for the process (partly waste from bio-refinery) of producing GX are abundantly available and very cost competitive. The product will have a significantly smaller carbon footprint than the type of binders that are used now. With 0.52-0.60 kg CO₂ per kg product the carbon footprint of GX is 5-10 times lower than that of existing thermoset binders. This means that it possibly saves 80%-90% on CO₂ emissions. The potential for replacement of current binders and thus CO₂ reduction is huge. In Europe alone over 5 million tons per year of thermoset binders are used in construction materials. Plantics aims for a 20% market-share as a midterm target.

More on Circular binder applications

CirBind aims the scale-up of the current lab-scale production (kg) of Plantics-GX resin (GX) to a 50-100 kg/batch plant at TRL5. The feedback from three high potential binder applications, partly in an industrial environment, is essential to adjust the production process and design/engineer a flexible production plant. This is done in close cooperation with knowledge institutes and end-users for selected applications. The resin will induce a step change in the production of this unique bio-based thermoset polymer and the introduction of applications in the Netherlands and Europe.

Our activities

The project entails both fundamental and application-oriented research combined with expert knowledge and the input from research institutes and end users. The project focusses on various aspects: on scaling up the GX bio-resin production; on the fundamental understanding of the chemistry of the polymerization for different formulations of the bio- resin and the interaction with other materials; on the development and testing of a specific binder application (one for each end-user). The Institute for Sustainable Process Technology will take care of the dissemination and the overall project coordination together with Plantics as project leader.

The project is executed in the Netherlands and Finland.
