Smart technology

The Renasci® waste processing system is a unique combination of high technology and connected mechanical, thermal and biological processes. Our system automatically selects and collects glass, ferrous and non-ferrous metals, plastics and biomass from the waste flow. The system then processes the plastics and biomass flows in an additional technology chain.


We separate plastics into recyclable and non-recyclable flows. We then use our patented P2F* system to convert the non-recyclable plastics into hydrocarbons for the production of diesel and petrochemicals.


We process biomass in a number of steps. In the first phase, we convert the biomass into biocoal using hydrothermal conversion (HTC). This biocoal is suitable for generating energy and for the production of syngas, biofuels and chemicals. In the second phase, we use enzymatic hydrolysis and fermentation to produce bioethanol and isobutanol.

We then convert the residual flows from the sorted waste and remaining items from the P2F and HTC processes into energy for internal use via a physical-chemical process at high temperatures. Finally, we use some of the inert residual flow as filler for building materials.

Locally adjustable input and output

Renasci® is the first initiative worldwide to offer bespoke solutions for local waste problems. We can coordinate the complete processing installation to your local situation and your specific input and output needs.


Each year, 120,000 tonnes of industrial, plastic and pre-treated household waste will be sorted fully automatically and converted into useful end products to the maximum extent possible.


Our advanced sorting line divides the waste into a variety of flows. Each material has its own characteristics with regard to magnetism, mass, form, reflection of infra-red light, etc., and the sorting installation uses these differences to divide the combined flow into separate sub-flows.

Ferro / non-ferro

We remove the ferrous metals using magnets.The non-ferrous metals are removed from the combined flow using an eddy-current system.


The plastics are divided into a recyclable flow and a non-recyclable flow.

The recyclable plastics are cleaned and conditioned for re-use.

Non-recyclable plastics are converted into raw materials for the production of diesel and petrochemicals

Organic materials

The organic materials (including paper & cardboard) are divided into a recyclable flow and a non-recyclable flow.

The materials in the recyclable flow are cleaned and conditioned for re-use.

The materials in the non-recyclable flow are converted into biocoal via hydrothermal carbonisation (HTC). These biocoal pellets have the same caloric value as natural coal.

In the second phase, we use enzymatic hydrolysis and fermentation to turn these materials into second-generation bioethanol, bio-isubutanol and GTBE.

The residue from this process can then be converted into biocoal via the HTC process.

Inert materials

Inert materials, sorting residue and byproducts of the various process are converted into energy and filler for building materials using physical-chemical catalysis. The energy is then used to generate electricity for the installation.
