Currently, mono-waste streams are used for pyrolysis mainly consisting of plastic or rubber. HydroCat's 'feedstock' consists of a mixed waste stream of biomaterial contaminated with plastic. Think of a tomato plant growing up a plastic stem, a banana in a plastic bag, coffee in a cup, or ocean plastic with seaweed.
In the Netherlands alone, 8,000,000 tons of waste are incinerated each year, of which about half can be used for HydroCat. Prevention by improving the recyclability of materials is the best approach. But practice shows that a lot of unavoidable waste remains. HydroCat's hydro-pyrolysis process enables this waste stream, which is now difficult to recycle and non-recyclable, is recycled more extensively and with a much lower CO2 footprint than incineration.
With the third generation of hydro-pyrolysis, raw material for producing plastic is produced in the form of biofuel. This (partly biogenic) fuel can be used to produce plastics or low-sulphur, green fuel for shipping.
Moreover, HydroCat's hydro-pyrolysis process delivers a better-quality product than biomass in a conventional pyrolysis process. This is caused by an integrated hydrogenation step that generates hydrogen, where oxygen is removed from the biomass molecules (deoxygenation).
In traditional, second-generation pyrolysis solutions, fossil hydrogen from an external source is added, which has a negative impact on the business case and CO2 footprint.
The HydroCat solution is therefore economically stronger on a much larger stream of mixed waste than traditional pyrolysis processes.
In the animation below we explain the HydroCat waste conversion unit and all it’s advantages.
