RUBIO's main Goal is to Produce bio-based PBS from Central Germany for the world market

We focus on the biodegradable plastic polybutylene succinate (PBS) , whose raw materials succinic acid and 1,4-butanediol can be produced both fossil and - as envisaged in our project - from glucose.

Based on five RUBIO collaborative projects, a total of 17 million euros (of which 12 million in funding from the Federal Ministry of Education and Research) will be invested over the next few years to achieve the following goals:


Waste materials from regional agriculture and forestry (e.g. fermentation and wood residues) are tapped as a raw material base for PBS production.

All technological steps of a PBS circular economy, from the extraction of bio-based succinic acid to the necessary polycondensation and processing procedures to recycling, are researched and optimised in a practical manner.

Formulations for a whole family of PBS types for a wide variety of applications such as packaging, transport, textiles, etc. are being systematically developed.

During the ongoing research and development work, the establishment of regional value chains will be started and PBS production will be scaled up from laboratory to industrial level.

Annual production of about 5,000 to 10,000 tonnes of PBS in the Central German Chemical Triangle for the German market is planned for 2024. In the following years, capacities in the region are to be expanded to 200,000 tons per year and more with the support of further investors, and international markets are to be developed.
