Lignin Industries materials for Polypropylene applications.

Renol® helps manufacturers meet sustainability goals without compromising on material strength or quality.

Renol® masterbatch for Polypropylene applications

Introducing Renol® for Polypropylene:
A masterbatch that reduces reliance on fossil-based materials while maintaining the high performance of conventional polypropylene, with added flexibility and a significantly reduced carbon footprint.

Renol® is made from 100% biobased materials: lignin and biobased oils. When we supply Renol® as a masterbatch, we blend it with a carrier polymer (the plastic material our customer will blend our Renol® with). In most cases, the masterbatch is a 50/50 mix of Renol® and the carrier polymer. This means that the final masterbatch has 50% Renol®—and therefore 50% biobased content.

It is versatile, suitable for extrusion and injection moulding, and integrates seamlessly into your existing operations—no adjustments in process equipment needed. It comes in granular form and works well with both recycled and virgin resins, offering a cost-effective alternative. For maximum CO2 reduction, blend up to 70% Renol® masterbatch with recycled PP or virgin PP.

Derived from a by-product of the forest industry, Renol® reduces fossil material usage and enables fully recyclable end products, contributing to a lower overall carbon footprint.

Benefits

  • Compatible with commercially available impact modifiers
  • Enables full recyclability with the lignin component bringing high amounts of antioxidants to the mix
  • Its natural color is a brown, reminiscent of the trees from which it is derived​
  • Possibility to colour in to other colours, except white and transparent colours
  • Strong forest and circular narrative​

Market fit

  • Industrial parts​

  • Building & construction​

  • Consumer products​

  • Automotive & mobility​

  • Gardening tools & outdoor furniture​

Reduce your carbon footprint with Renol® and
recycled Polypropylene

Growing trees act as a carbon sink, absorbing more CO2 than they release, making Renol® a carbon-negative material and contributing to significantly lower CO2 footprints in the end products.

The Renol® masterbatch for Polypropylene—containing 50% Renol® and 50% recycled Polypropylene—has a total GWP of 0.73 kg CO2-eq./kg and a temporary biogenic carbon uptake of -1.21 kg CO2-eq./kg.

In summary, this Renol® masterbatch has a CO2 footprint of -0.48 kg CO2-eq./kg.

FAQs

  • Renol® is made from 100% biobased materials: lignin and biobased oils. When we supply Renol® as a masterbatch, we blend it with a carrier polymer (the plastic material our customer will blend our Renol® with). In most cases, the masterbatch is a 50/50 mix of Renol® and the carrier polymer. This means that the final masterbatch has 50% Renol®—and therefore 50% biobased content.

  • Renol® is detectable and sort with the primary polymer in conventional recycling systems, up to certain concentrations. For polypropylene, this threshold is 60% for NIR and 40% for sink-and-float weight. Detailed recycling reports from Svensk Plaståtervinning are available upon request for further insights.

  • No, Renol® pellets are primarily biobased, but they are not biodegradable according to EN standards. However, this is actually a benefit, as they are designed to be recyclable, contributing to a circular economy rather than breaking down into the environment.

  • It offers a refined colour range, from soft greys, pastels and to deep browns and blacks.

  • We focus on cradle-to-gate because it reflects the stages of production we directly control and take responsibility for, up until the material leaves our facility. What happens beyond that—how the material is used and disposed of—depends on the end user, which is outside our direct control.

    However, cradle-to-grave data can be provided through collaboration with the end user for a more complete view of the product’s life cycle.
