Using and establishing renewable raw materials and recyclates for the production of plastic pipes is the goal of the innovation network planned by the SKZ Plastics Centre in cooperation with HeiQ RAS AG from 2024. These are to be established for the supply industry, taking into account process capability, processability and economic efficiency.
Within the framework of the innovation network "Sustainable plastics in the supply infrastructure", the competences of the partners are to be bundled along a value chain. The aim is to achieve the complete production of plastic pipes based on renewable raw materials and recyclates. First of all, it is necessary to prove the long-term stability of bio-based plastics as well as to examine chemical stability, durability and fatigue strength (also under load) in detail. The focus of the network is to create confidence in the durability of bio-based plastics and the use of recycled materials.
In addition, technological solutions are to be developed and realised in a timely manner. Development topics are taken into account by initiating and implementing funding and cooperation projects in the network.
The research results from these projects are subsequently incorporated into standards and requirement catalogues of the relevant specialist networks and users. In this way, the use of sustainable raw material sources, especially sustainable bio-based plastics, for industrial applications is expanded. In the long term, the CO2 footprint can be reduced and sustainable material cycles established for industry.
The planned network brings together partners from SMEs, industry and science. If approved, funding will be provided by the Central Innovation Programme for SMEs (ZIM). Companies, institutes or universities interested in participating in the network can contact project manager Dr. Ruben Schlutter for further information: r.schlutter@skz.de
Bio-based raw materials for the production of plastic pipes
Pipe systems in the supply infrastructure (e. g. for drinking water supply) must meet high quality requirements, such as a long service life, as well as economic requirements. Currently, plastic pipes are made from petrochemical-based raw materials. Modern PE plastics are made for use in technical infrastructure. Properties such as corrosion resistance, chemical resistance, environmental compatibility and durability make them superior to conventional pipe materials. The switch to bio-based raw materials would sustainably secure the future viability of pipe manufacturers in Germany against the backdrop of increasing political demands for a circular industry. In addition, it can be assumed that petrochemical products will become more expensive due to the shortage of oil, while bio-based alternatives will tend to become cheaper.
