Plastics are so common in your lives and you know it when you see it, yet you presumably can’t find the difference among all plastic types. How to categorize and recycle plastics? For a beginner, there is no difference between HDPE and LDPE. Unless you work in the plastics recycling or plastics making industry.
Plastic is one of the popular materials our clients want to process. It’s also the most complicated material to recycle because plastic wastes often come in a mixture and often is highly contaminated.
Luckily, a product made of plastic is often stamped with a code, which is a number between one and seven inside a small triangle made of arrows. It’s the number inside the triangle that counts because each number corresponds to a different type of plastic.
Follow this number, we can categorize plastic waste and make our recycling machines’ jobs easier. Because once the plastic waste is sorted, the rest of the job is size reduced by shredder and crusher, washed by friction washer.

Recycling machines like sink-float tank can discharge non-PET products by density difference.
2. HDPE – High-density polyethylene
Yes, HDPE products CAN be recycled.
HDPE plastics are also extremely common. They’re those used to make paint pails, milk jugs, shampoo bottles, jerry can, chemical drum, oil canister, cleaning product containers and detergent bottles. Often they are compressed and baled, which are easy to be broken down by a shredder.
