LyondellBasell together with Röchling Medical have announced a step forward towards their ambition to advance the circular economy. The companies created eye drop containers made by Röchling Medical using CirculenRenew polymers. LyondellBasell CirculenRenew polymers offer a variety of polypropylene (PP) and polyethylene (HDPE and LDPE) grades that are equivalent to virgin resin quality.

LyondellBasell CirculenRenew grades support the use of renewable feedstocks from bio-based sources that are not in competition with food sources. LyondellBasell and Röchling have collaborated closely to find the right grade for Röchling's eye drop containers. After several trials, the project team has chosen a Low Density Polyethylene (LDPE) not only because of its high purity, which is necessary for pharmaceutical applications, but also because it was ideal for use in blow molding.
