Exploring alternative technology routes for recovering value from selected plastic waste streams through thermal and advanced recycling processes.
Discuss Your ProjectNot every plastic waste stream is equally suited to conventional mechanical recycling.
For selected materials, advanced recycling and pyrolysis provide alternative processing routes in which plastic waste is thermally converted into other potentially useful products.
Ant Spirits is developing this application area together with technology partners, supporting customers in evaluating suitable processing concepts according to their feedstock, capacity and project requirements.
Pyrolysis is a thermal process used to decompose suitable plastic materials into different product fractions.
Unlike mechanical recycling, where the polymer is physically prepared, melted and reprocessed, pyrolysis uses thermal decomposition to transform suitable plastic feedstock. Depending on the technology, feedstock and operating conditions, the process can generate liquid, gaseous and solid output fractions.
The suitability of a particular waste stream depends on its composition and the intended processing route.
Polyethylene-based plastic waste streams.
Polypropylene-based plastic waste streams.
Selected polystyrene waste applications.
Selected mixed plastic waste streams subject to process evaluation.
Liquid product generated through thermal decomposition of suitable plastic feedstock.
Gaseous products can be generated as part of the pyrolysis process.
A solid carbon-containing fraction may remain following thermal conversion.
Additional liquid fractions may be generated depending on the selected technology and feedstock.
Catalysts can form part of selected pyrolysis processes depending on the technology and processing objective.
Areas within our current technology scope include:
The performance of an advanced recycling process depends heavily on the characteristics of the incoming waste stream. Polymer composition, mixed-material content, contamination, available quantity and required outputs need to be understood before an appropriate technology route can be considered.
Ant Spirits works with customers and technology partners to understand these requirements and evaluate potential processing solutions.
