Our 2023 patented HIPE-REC® (HIgh PErformance RECovery) process can produce a decent cellulose pulp.
We are convinced that this process can upgrade regional available feedstocks or wastes to quality products for the fiber or paper industries. First proofs of principles with different feedstocks have exceeded our expectations.
For instance Austrian wheat straw was investigated as a potential raw material for our new HIPE-REC® technology, applying distillable ionic liquids to selectively extract lignin.
The fractionation of the cellulose and lignin fraction as well as the recycling of the distillable ionic liquid have successfully been demonstrated.
The broadening of the potential feedstock portfolio for the HIPE-REC® process is essential. Besides spruce – the main soft wood species in Austria – which was previously investigated, the latest investigation of a grassy biomass feedstock is demonstrating the flexibility of this new technology.

“With every new feedstock we gain experience and fine tune our HIPE-REC® technology. This is exciting, and we are very happy with the high quality of our generated lignin and cellulose. The obtained HIPE-REC® products will now be tested in various processes developed by our cooperation partners to demonstrate the full potential of the technology. Promising preliminary tests offer a wide range of potential uses. We will first start with the production of paper, biobutanol as well as textile and technical cellulose filaments.ard-thinking textile production.”
