How Are The Different Types Of Plastic Sorted During Recycling?

There are plastics everywhere, whether we like them or not. You can see the hundreds of plastic goods you use if you open the fridge or glance around the house. If you look closely, you’ll see a recycling symbol on the back, front, or one of the sides of every plastic item. This triangle of pursuing points represents a number between 1 and 7 and serves as a recycling indication. The bottle recycling depot in Calgary and worldwide gives valuable information about the recyclable resin and the item’s capacity to be recycled. Remember that just because an item has a plastic recycling code printed doesn’t imply it can recycle. All it does is provide data regarding the potential for recycling. Suppose you are concerned about getting insights about the types of bottles for recycling at a bottle return depot and sorting methods. So please continue reading.

Plastic Bottle Sorting

Many different types of plastic bottles can be sorted and separated before recycling at the return bottle depot in Calgary and elsewhere. It is pretty easy for the bottle depots to get the pre-sorted bottles. In another case, bottle depots have different technologies to separate bottles so you can easily recycle them. Let’s explore some kinds of plastic bottles and their method of sorting.

1. polyethylene terephthalate

This term refers to one of the most popular thermoplastic polymer resins, polyethylene terephthalate. We often refer to it as PETE or PET plastic. Where does PET plastic fit into our everyday lives? So, this plastic is often used for water bottles and other drinks, jugs, and containers for food, salads and oil, fiber for clothing, and mouthwash bottles. This plastic is often transparent and is meant for a single function.

2. Density polyethylene

One of the most certain plastics available today, High-density polyethylene (HDPE), is a material with excellent wear resistance due to its high strength-to-density ratio. Since HDPE materials are unaffected by temperature extremes, they may utilize year-round. There is no danger in recycling this plastic. HDPE is widely used in production because of its durability and dependability.

· Cosmetic and cleaning product containers that won’t break easily

· Outdoor furniture such as stools, seats, and sunbeds

· For the playground, we have toys.

· There are several plastic bags here.

· Adaptable conduits

· cases for bottles

· Rope

· Enclosures made of plastic

· Plastic milk, juice, and water containers

3. Polypropylene

Polypropylene (PP) plastic seems to be the second most commonly manufactured plastic after polyethylene. Because of its low weight, high resistance to heat, and high strength, PP is used in many types of packaging. In current times, pp Plastic is often utilized for

· Cups for yogurt

· Cereal box liners

· Toilet paper products

· caps for plastic bottles

· Kitchenware

· Use of disposable dishes, glasses, and silverware

Because of its widespread usage in food packaging, many people are curious about how PP reacts inside the human body. To what extent does polypropylene not pose any danger? Is it true that PP plastic is safe to use in the microwave? The recycling sign with this plastic often indicates that a product may be cooked in a microwave without noticeable damage. Even microwave-safe plastic has been linked to asthma attacks and hormonal disturbance, so using glass containers is preferable.

Typically, A Series Of Sorting Stages Is Used To Organize Plastic Trash.

1. These comprise magnitude sorting (whichever using sieves or manually), elimination of non-recyclables (like glass and metal), separating plastics, and granulating into recyclate.

2. You could also use gravity in an airflow (air classifier) or a water flow to filter out unwanted particles (sink-float).

3. You can also use the magnetic characteristics of metals to extract them; for ferrous metals, this is accomplished by magnetic attraction, and for nonferrous metals, this is accomplished through induced magnetic repulsion.

4. Some polymers may be separated using gravity, such as polyolefins, compared to PVC or PET, which has a density of 1.4 g/mL (which has a density of 0.9 g/mL). Electrostatic or magnetic fields may help refine the gravity sorting, but the improved accuracy looks pretty vulnerable to future trash contamination.

5. It is more popular, however, to use a conveyor belt to spread out the different plastics. Then it would help if you used an infrared sensor (e.g., near and short wave infrared SWIR or NIR). To identify the plastic to sort, use an actuator or air jets to sort the plastics.


it is expected that this article will help give you a complete guide about different types of plastic bottles and how efficiently you can sort them at a bottle recycling depot in Calgary and your nearby area. Because when bottles are sorted, you can efficiently and effectively recycle them. Moreover, you can get extra cash on pre-sorted bottles at the bottle return depot.
