While our standard PET bottle washing lines are sufficient for most facilities, custom setups with additional machinery and increased capacity can be designed for your specific needs.
Our turnkey PET bottle washing line consists of a series of our plastic recycling machines connected using various types of conveyor systems.
Debaler Machine: The first step in our plastic bottle washing line is to break the compacted bales of PET bottles into a free flowing stream. Once the bales are “busted”, the bottles can move freely onto the next machine.
Trommel: An optional piece of equipment, the trommel is a slowing rotating tunnel lined with small holes. The holes are slightly smaller than the PET bottles so small pieces of contamination (such as glass, metals, rocks/dirt, paper, etc…) can fall through while the PET bottles move onto the next machine.
Wet Plastic Granulator: Sometimes referred to as a plastic crusher, our plastic granulator machine cuts the PET bottles into small flakes between 10-15mm in size. With water constantly spraying into the cutting chamber, this wet granulation process pre-treats and partially cleans the material before moving onto the next equipment.
Air Classifier: Air classification is a way to separate lighter materials from heavier ones. The main purpose of using the air classifier is to remove contaminations such as paper, cardboard, and plastic labels away from on PET flakes.
Sink / float Separation Tank: Using water as a medium, materials that float are separated from materials that sink. In the case of plastic bottle recycling, PET plastic will sink while plastic film (bottle labels) and PP/PE plastic (bottle caps) will float. A screw conveyor at the bottom of the sink float separation tank moves the PET plastic to the next piece of equipment.
Hot Washer System: Hot washed PET flakes are of higher value because this process dissolves glues (used to glue labels onto the bottles) and leftover beverages/foods that are difficult to remove in a cold wash process. Although you can just use water in the hot washer system, adding washing agents can added for better results.
Friction Washer: A efficient piece of cold water washing equipment, the high speed friction washer uses friction as a mechanical way to remove any hard to remove dirt and debris from the PET flakes.
Dewatering Machine: The first step in the drying process, our centrifugal dewatering machine uses centrifugal force to remove a large portion of water within the PET flakes before moving forward onto our thermal dryers.
Thermal Dryer: PET flakes are vacuumed out of the dewatering machine into the thermal dryer where it travels down a series of stainless steel tubes mixed with hot air. This process removes any remaining moisture by dehydration. An attached cyclone separator mixes the PET flakes with cool air preparing it for storage in the product silo.
Product Silo: A storage tank for the clean, dry PET flakes.
Pelletizer / Extruder: For the most part, PET flakes are used as is particularly in manufacturing polyester fibers. However, we do have customers requiring plastic pelletizing machines such as our single-screw extruder pelletizers and twin-screw extruder pelletizers.
Our PET washing line produces high-quality PET flakes that are clean and contamination free. Below are typical benchmarks for PET flakes produced from this recycling line:

Washing machines of PET bottle washing plant
The necessary washing machines for cleaning PET flakes are a washing tank, hot water washing tank, and frictional washing machine. In fact, the PET washing machines are adjustable to choose from, people with a low budget can choose these three machines to wash their plastic flakes.
But if the waste plastic bottle is too dirty or the plant would like to use more washing equipment to ensure the plastic’s cleanliness, the number of washing tanks, hot water washing machines, and frictional washing machines can increase to two or three.
PET bottle washing line
Our plastic bottle recycling line can also adjust the kind of washing machine according to the customer’s order and the raw material. The whole washing step includes three washing machines, which are two washing tanks, a hot water washing tank, and a friction machine. The following video shows the customized plastic bottle recycling line which uses only one piece of washing equipment.
How are recycled plastic bottles reused?
Many people may wonder where recycled plastic water bottles have gone. In other words, many people know that plastic bottles can be recycled, but they don’t know what they can do after recycling.
Prospects of the plastic bottle recycling business
A large part of the production of plastics depends on petroleum. The recycling of plastics is the recycling and utilization of petroleum resources.
From a macro perspective, the prospects of the plastic water bottle recycling industry are very optimistic. At present, the main recycling industries include waste metal recycling, waste paper recycling, waste rubber recycling, and waste plastic recycling. The reuse rate of waste metal can reach 70-80%, the waste rubber can reach 47%, and the waste paper 20-30%. However, the reuse rate for plastic is less than 30%.
Therefore, the recycling market of waste plastics is still very broad, and the plastic bottle recycling line is also very popular and practical. Combined with the global attention to environmental protection, resource conservation, and other issues, the requirements of plastic bottle recycle machines will keep increasing, and the development potential of the plastic recycling industry will only grow.
Profit of plastic bottle recycling machine
The main methods of dealing with plastic waste mainly include incineration, disposal in a landfill, and recycling. Plastic waste recycling maybe not be a very profitable business in many people’s opinion. Exactly, one plastic bottle has very low value, however, in the big cities, millions of waste mineral water bottles will be produced by people at least, one-ton mineral water bottle probably has 60 thousand plastic bottles， which can make a profit of about 300 dollars.
On the surface, the plastic bottle recycling line is a business with low profit, in fact, if you have a stable supply, comprehensive knowledge of plastic, and a team, plastic recycling is a profitable business for you.

Generally speaking, the production range of this production line is 500- kg per hour. The maximum output can reach more than 6 tons per hour.
What is the energy consumption of plastic bottle recycling machines of 500 kg per hour?
Processing one ton of material consumes 60 kWh of electricity.
Is it necessary to wash the PET flakes four times?
It depends on your raw materials, if your plastic bottles are not very dirty, it is possible to clean them less than four times.
How to choose PET recycling machines with a low budget?
Because the cleanliness of plastic bottles is different, the washing equipment they need is different too. A washing tank, a hot water washing tank, and a frictional machine are necessary for recycling PET bottles, if one has a low budget, he can choose these three machines at least.
But if he has a high budget, he can choose more three PET recycling machines, for example, one washing machine, two or three hot water washing machines, two frictional machines. Machines in different numbers will provide different effects. More cleaning machines can wash waste PET flakes cleaner, which also has a higher price.

Plastic bottles can be seen everywhere in our day-to-day lives. Products such as water bottles, soda bottles, cooking oil, food containers and other products are all made up of plastic. As we know there are different types of plastics but for producing bottles that contain food or potable water, we prefer Polyethylene Terephthalate which is also commonly known as PET. This material produces bottles that are lightweight, yet strong and durable. Although the process is slightly based on proprietary methods, the basic method for producing bottles is universal.
The empty PET discarded from the consumer is known as Post-consumer PET in the recycling industry. The government or local recycling agencies collect this waste and ship it to the material recovery facilities.
PET bottles are highly sophisticated material and it is highly valuable to throw it in a bin. It can be recycled, which means we can produce many new products using the used bottles. Every year billions of bottle waste get around the world. Collecting the whole waste can drastically reduce the waste and safeguard the environment. This recycling of PET starts from collecting the huge waste and compressing it to the huge bales and transferring it to the recycling plants and the PET bottles are crushed into flakes.
Bottles made of Polyethylene terephthalate can be used to make lower grade products. PET flakes means small fragments of PET bottles which are broken off from the whole by cutting or crushing operations.
After undergoing the recycling process, we get the end product in the form of flakes which is known as PET flakes. After testing the quality of flakes/pellets and ensuring it is 100% safe they are turned back into bottles.
To produce the PET bottles, we use an injection stretch blow molding machine or PET blow molding machine. This sophisticated machine melts the flakes then dries it and turns it to perform. The injection molding injects the performs into desired molds and the robots cool and pay the production. We need a blow molding machine to cool the performers. Finally, the performers come out in perfect shape which is easy to transport and ready to make new bottles. This way of making bottles from recycled plastics there won’t be any wastage or nothing to send to landfills. We can’t find unnecessary drain on new resources and it’s the best resource and has wide usability.
Here at bright PET washing line industries, we aspire to make top-grade PET flakes for our clients to meet the requirements on a satisfactory level. Post-consumer PET bottles are crushed, shredded, hot/cold washed and sorted into different colors that are offered for sale to manufacturing companies directly. PET flakes are used to produce a range of products starting from polyester sheets to turning them back into PET bottles.
These are used for several purposes such as:-
Polyester:- It accounts for roughly 60% of the world’s production of PET, more than what is used for making bottles. Polystyrene fabrics are used in clothes, home furnishing, shirts to hats, curtains, blankets etc.
Polyester Strapping:- This is a very strong material and can take up a lot of tension before elongation. It can be used to produce polyester strapping which is used in the packaging industry.
Polyester films:- Wide area of PET application is polyester films. Single and multi-layer films used for manufacturing industrial packages and food product packages.
Polyester Sheet for thermoforming:- We can use this sheet at least four ways such as insulation materials, packaging for toys, containers for grocery and food items.
Textile fibers:- Particular properties such as tensile strength, abrasion resistance and low moisture absorbing capacity, make the PET the most important raw material for manufacturing synthetics fibers. Textiles made of PET are crease resistant, weather resistant and fast drying, which makes them an excellent choice for manufacturing sports clothing- everyone can make a use of cozy polar fleece during winter time.
It may include labels and caps. These may have a thin PVC layer such as 88% PET, 4% PVC and the rest are multi-layer. Moisture is a common feature in cold washed PET Flakes. We should expect around 1% moisture. They can come as transparent as well as dark, gren, blue or in other colors.
These flakes are produced by crushing used PET bottles and may come with or without labels and caps. These flakes are widely used in industries for numerous purposes such as:-
Polyester resins:- PET in the form of resins is used as a component of paints and lacquers, and when combined with curing agents, it is used for making durable composites on the basis of polyester textiles.
Bottles:- Roughly 30% of the world’s production of PET is used to produce bottles. After the bottles are used by the consumers, they are collected, cleaned and crushed , then hydrolysed to be recycled back into bottles.
