How to Recycle Polystyrene?

Polystyrene recycling is of increasing significance now. Commonly seen Polystyrene foam includes expanded Polystyrene (EPS), extruded Polystyrene (XPS) and Polystyrene paper, such as food tray and cups.

Polystyrene Foam Recycling Steps:

1. Collect waste polystyrene
2. Volume reduction, via an EPS compactor
3. Ship to recycling company to do the pelletizing
4. Reuse to make new products like picture frames

Why to Recycle Polystyrene:

Polystyrene is one of the most commonly used thermoplastic plastics,transparent and with the translative temperature higher than 100 degrees Celsius. But it is not easy to decay and degraded by recycle Polystyrene natural microbes, becoming the white pollution. So the polystyrene foam recycling is of great necessity.

Polystyrene Recycling by Volume Reduction:

All kinds of Polystyrene foam can be recycled and reused by different methods. But most Polystyrene products are currently not recycled due to the lack of incentive to invest in the compactors and logistical systems required. Generally, Polystyrene can not be recycled by curbside, Due to the low density of Polystyrene foam; it is not economical to collect. As a result, manufacturers cannot obtain sufficient scrap, so Polystyrene foam recycling is a business of great potential.

However, if the waste material goes through an initial compaction process, the material changes density from typically 30 kg/m3 to 400 kg/m3 and becomes a recyclable commodity of high value for producers of recycled plastic pellets. Volume reduction techniques, such as compaction and densification, significantly minimize the material's size, making it easier and more cost-effective to transport and process. This process reduces the environmental footprint of PS waste, and once compacted, the material can be transported to specialized recycling facilities for further processing or conversion into new products.
