Web220322: Hydrothermal Liquefaction – advanced carbon recycling for natural and synthetic polymers

Access the webinar recording

Recycling of mixed organic wastes can be difficult unless you have the right technology. Hydrothermal liquefaction is a viable technology for the production of  a high value biocrude oil which can be upgraded into transport fuels.

Hydrothermal liquefaction technology uses water under high temperature and pressure to enable advanced carbon recycling. The process converts polymers from both natural and man-made sources into smaller, less complex and cleaner materials which can be used as is or further upgraded to drop in low carbon intensity (CI) transportation fuels, chemicals and/or intermediates to enable circular economies.

The wastes able to be chemically recycled by liquefaction include municipal solid waste, biomass, plastics and tyres effectively transforming waste into a resource. The technology just needs feedstocks to be source-segregated so that there is no glass or metals, which can be achieved using current collection models, then fine-tuned to process the different feedstocks.

About the presenter

Alan Del Paggio has had 35 years in industrial catalysis with Shell. Building upon experience gained in the production of fossil-crude-derived petrochemicals, he shifted focus later to develop more sustainable solutions. He led activities to identify, validate, scale up and deliver sustainable commercial solutions including production of low carbon-intensity petrochemicals and base oils, renewable petrochemicals and hydrogen.

Most recently he has joined Licella to help deploy Cat-HTR™ technology to enable circular economies in post-consumer waste conversion and to upgrade biocrude to renewable ‘drop in’ hydrocarbon fuels.
