Chemical recycling 101 - Did you know?
Chemical recycling of plastics is an emerging sector that provides concrete solutions to the management of the end of life of plastics. As a driver of change and innovation, the chemical recycling of Pyrowave's technology allows the reintroduction of plastic waste in the manufacture of new products and packaging.
Get to know your facts about the chemical recycling of plastics!
Pyrowave’s microwave technology breaks down plastic into its elementary constituents – which are decontaminated at extremely high temperature and purified in the process - allowing it to be reused for the same applications as virgin resin.
Pyrowave offers a low-carbon solution to restore the full value of plastics at the end of their life and reduce the extraction of virgin resources.
It’s possible to melt all plastics together, however, it’s impossible to reuse this mixture in the same commercial applications as with virgin material.
Pyrowave’s low-carbon electrification of chemical process allows to sustainably recycle polystyrene by breaking it down into high quality and high purity styrene monomer, which can then be reused for the same applications as virgin resin.

How effective is the Pyrowave technology?
Pyrowave technology returns polystyrene (PS) to its pristine state. None of its properties are altered, allowing new products to be made with the same quality. Pyrowave microwaves can reach very high temperatures, destroying all contaminants. Pyrowave technology is the most powerful and highest yielding technology on the market, with liquid yields of nearly 98% on a pure PS basis. This means that for every ton of pure polystyrene injected, the PW6 reactor produces 980 kg of liquid containing the styrene monomer.
The amount of styrene in this liquid can reach 70%, which represents the highest styrene production rate in the industry.
Can Pyrowave technology remake food containers?
Microwaves heat can reach a high intensity, destroying all contaminants and returning the plastic to its basic constituents identical to virgin constituents. The qualities of polystyrene are not affected by the chemical recycling of the Pyrowave technology. Food packaging and containers produced with polystyrene recycled with Pyrowave technology therefore meet the same standards and food quality requirement as those made from virgin material.
Is the Pyrowave technology energy consuming?
Any process is energy-consuming. Pyrowave microwaves work with electricity, a source of renewable energy! Therefore, the Pyrowave technology consumes 15 times less energy and emits 5 to 7 times less GHGs compared with the manufacture of virgin polystyrene from petroleum.
The Pyrowave process consumes about 0.5 kWh of electricity per kg of pure material processed.
What is the quality level required for the polystyrene waste recycled by the Pyrowave technology?
The higher the quality of the plastic waste, the higher the efficiency of the Pyrowave technology. However, the microwave technology is very robust and can destroy most contaminants usually found in post-industrial and post-consumer plastic waste. Enquire with our team for additional information on the specifications.
Are the costs of recycled plastic with Pyrowave technology higher than those of virgin plastic?
The collection, transportation and sorting costs associated with post-consumer plastic recycling and the scarcity of the material make it expensive. The environmental benefits of recycling are essential to preserve our resources and our health. Governments could adopt mandatory recycled content targets for plastics to increase demand and reduce costs.
