The PET Plastic Recycling Process
PET (polyethylene terephthalate) is a common plastic used worldwide. It’s found in many packaging items. Recycling PET plastic helps reduce landfill waste and saves natural resources8. The recycling process turns old bottles into new, useful materials.
Step 1: Collection
First, used PET bottles are collected. Billions are recycled in Europe each year9. People can recycle at curbside, local centers, or bottle bill depots.
Step 2: Sorting
Then, the bottles are sorted by type and color. This ensures the quality of the recycled PET. Advanced scanners help sort different plastics.
Step 3: Cleaning
After sorting, the bottles are cleaned. This removes labels, caps, and leftover contents. They are washed, ground, and sorted again for clean plastic8.
Step 4: Shredding
The bottles are shredded into flakes. Machines like the RUNI Screw Compactor make this step efficient8. The SK240 can process 5,000 0.5-liter bottles per hour. The SK370 can handle 20,000 0.5-liter or 8,000 1.5-liter bottles hourly8.
Step 5: Melting and Extruding
The flakes are melted into recycled PET pellets or fibers. Nitrogen is used to make the material food-grade. Mechanical recycling keeps the environment safe8. The pellets are used in packaging, creating a closed-loop system89. They also make fabrics for various products9.
| Recycling Step | Description |
|---|---|
| Collection | PET bottles are collected through recycling programs or deposit schemes |
| Sorting | Bottles are sorted by material type and color using advanced technologies |
| Cleaning | PET bottles are washed and cleaned to remove contaminants |
| Shredding | Clean PET is shredded into small flakes for further processing |
| Melting and Extruding | PET flakes are melted and extruded into recycled pellets or fibers |
Mechanical Recycling vs Chemical Recycling
There are two main ways to recycle PET plastic: mechanical and chemical recycling. Both aim to reuse PET plastic but work differently. They also produce materials of varying quality.
Advantages and Disadvantages of Mechanical Recycling
Mechanical recycling melts PET plastic to make new items. It’s more eco-friendly, needing less energy and less CO2 emissions than chemical recycling10. Yet, the recycled plastic might not be as good due to contamination and mixed materials. This can limit its use in food packaging and making brightly colored plastics10.
Even though it’s better for the environment, mechanical recycling gets less funding than chemical recycling10. In 2021, only 8.3% of plastics worldwide were recycled from post-consumer waste11. In Europe, 10.1% of plastics were recycled from post-consumer waste11.
Advantages and Disadvantages of Chemical Recycling
Chemical recycling breaks PET into its basic parts for making new PET. It can create higher-quality recycled PET. But, it needs more energy and might harm the environment with chemical use10.
Chemical recycling gets more funding and support than mechanical recycling. A chemical recycling plant in Rotterdam got nine million euros for a total cost of EUR 200 million from investors10.
Choosing between mechanical and chemical recycling depends on what you want to make and the environment. To get better recycled plastic, we need to invest in both methods. Also, improving how we collect and sort plastic is key. Recycling plastic waste increases by 13 times when collected separately, and by 80 times for packaging waste11.
Challenges in PET Plastic Recycling
PET plastic can be recycled, but there are big hurdles. Food residue, labels, and other non-PET materials can ruin the recycling process12. In the U.S., about 27 percent of PET bottles are collected. But only 18 percent are recycled, and about 9 percent end up in landfills12.
There’s also a problem with recycling infrastructure and public awareness. Sorting different types and colors of PET is expensive and slows down recycling. This makes people less likely to invest in better recycling tech12. Plus, recycling rules vary by place, making it harder to recycle12.
How people dispose of things also matters. Every year, the U.S. throws away about 4.6 billion pounds of PET in landfills12. This is bad, given that 12.7 million tons of plastic waste reach our oceans every year13.
We need everyone to work together to fix these problems. Governments, industries, and consumers must improve how we collect, sort, and recycle PET. Europe wants to recycle 50% of plastic packaging by 2025, with Spain aiming for 60% by 203013. But Spain’s demand for recycled PET doesn’t match its supply, showing we need to act fast13.
Creating a European Strategy on Plastics is urgent. Companies in the plastic recycling field must work together13. We need to balance the demand and production of recycled PET to meet our environmental goals13. Also, making sure recycled products are safe and clean is crucial13.
