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	Описание
Collection	PET bottles are collected through recycling programs or deposit schemes
Сортировка	Bottles are sorted by material type and color using advanced technologies
Очистка	PET bottles are washed and cleaned to remove contaminants
Измельчение	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 загрязнение and mixed materials. This can limit its use in пищевая упаковка 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 инфраструктура переработки 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.

Innovations in PET Plastic Recycling Technology

The world is facing a big challenge with plastic production. It’s expected to double by 2050, leading to more plastic waste. New ways to recycle PET plastic are crucial. They aim to make recycling better, faster, and more efficient.
