What is depolymerization?
Recycling through depolymerization involves breaking down the bonds connecting monomer blocks in the long polymer chain without damaging monomers themselves. This helps separate and purify monomers more easily than purifying polymers. Several depolymerization methods are available to break down the PS molecular bonds. Pyrowave has developed a unique technology using microwaves. The prominent feature of this technology is that it helps break down these bonds very precisely without damaging the monomer blocks, while other technologies destroy a significant number of blocks in the process.
The Pyrowave technology generates monomers which are screened out to be purified and to extract dyes and additives. These monomers are then repolymerized to generate a new PS.
