Which has a higher recycling value: plastic pyrolysis recycling(chemical recycling) or plastic granulation recycling(mechanical recycling)?

In the ongoing increasement of plastic waste, two popular plastic recycling methods—plastic pyrolysis recycling and plastic granulation recycling—have emerged. In this passage, we will have a brief discussion about these two plastic recycling solutions:

Plastic Pyrolysis Recycling

Plastic pyrolysis recycling, also known as plastic chemical recycling. Conversely, breaks down plastic waste into valuable components such as fuel oil, carbon black and combustible gas via high-temperature decomposition in an oxygen-free environment. This method stands out for its ability to handle a wider variety of plastics, including plastic type 2 (HDPE), plastic type 4 (LDPE), plastic type 5 (PP), plastic type 6 (PS), plastic ABS, plastic cable, plastic sheets, plastic bags, aluminum plastics, etc. The resulting products have wide applications and large market value.

Plastic Granulation Recycling

Plastic granulation recycling, also called plastic pellet recycling or plastic mechanical recycling, which starts with shredding plastic waste, followed by melting it down into small pellets. These pellets serve as raw materials for new plastic products. The simplicity of this process makes it cost-effective and accessible for numerous recycling plants. However, this recycling solution commonly recycle single-type plastics, which has higher requirements on the types and quality of plastic waste. For mixed plastic waste, it's not suitable for granulation recycling.

Value Comparison

• Economic Value

Economically, the answer varies based on market conditions. Plastic granulation recycling has lower initial costs due to its simplicity, but the market for recycled plastic pellets is unstable, swayed by the price of virgin plastics. Pyrolysis recycling, though more complex and expensive to establish, can yield high-value products like fuels and other valuable products, potentially providing better long-term profit margins.

• Environmental Value

Both methods help reduce plastic waste in landfills and oceans. However, pyrolysis recycling has a greater potential to mitigate the overall environmental impact of plastic waste. By converting plastic into energy sources, it lessens the dependence on fossil fuels, contributing more significantly to environmental sustainability.

In summary, neither plastic pyrolysis recycling nor plastic granulation recycling can be declared as having inherently higher recycling value. The choice between them hinges on factors such as the types of plastic waste available, local market dynamics, and environmental goals.
