Plastic recycling lines contain washing basins, crushing machine, agglomerator, drying unit, granule extruder and packaging unit.Waste plastic recycling is recovery process of waste plastics and producing reusable raw material. Recycling of plastic starts by sorting waste material according to their resin types such as polyethylene, polypropylene, polystyrene, pet, pvc etc. Clean plastic waste can be melted and converted into pellets (granules) by using granule extruders.Before extruding, a size reduction or densifying process might be necessary. This can be done by using crushing machines or agglomeration machines. Contaminated plastic material has to be washed and dried first. For example plastic shopping bags which has been recovered from city waste has to be washed thoroughly before granulated. These shopping bags are made with high density polyethylene (hdpe) or low density polyethylene (ldpe). Agricultural films such as greenhouse covers (ldpe) also can be recycled.
Advantages of Plastic Recycling Line
Short Residence Time
The short residence time in the system largely avoids thermal damage, so that the chemical properties of the recycled material hardly differ from virgin material. Material changeovers are possible within minutes, so that production interruptions can be reduced to a minimum.
High Flexibility
The fully automated control of vacuum, extruder, metering, degassing residence time and filter change ensure on the one hand a consistently high quality of the recycled material and on the other hand enable the operator to use flexible and more cost-effective input materials.
Low Energy Consumption
The compact design and short residence time result in low energy consumption. Each input to the extrusion process is designed to be usable for the following process step. This significantly reduces the electricity, gas consumption and co2 footprint of the recycling process.
High (super-clean) Decontamination Performance, Even Suitable For Food Contact
In a single extrusion step, harmful contaminants can be removed so thoroughly that the repelletized material can be used in contact with food. Various regional approvals for pet, ps, hdpe, ldpe, and pp are available.

Working Principle of Plastic Recycling Line
Sorting is the first stage in the process of recycling plastics. This process helps in removing contamination from the material, which may render the recycled material un-reusable.
Polyvinyl chloride (pvc), the polyethylene terephthalate (pet), and the high-density polyethylene (hdpe) are carefully separated to remove contamination before moving to the next stage.
The next processing stage is the size reduction of the material. The machine cuts the material into smaller sizes that make it easy for further processing. Enables easy packaging and recycling.
The shaft shredders and the granulators ensure that the material a cut into the needed size. Some plastics vary in hardness, thickness, and weight. The shaft shredder cuts them well by rotating the blades.
The granulator consists of a rotor that is attached to blades. The motor is rotating within a chamber that contains a grid floor. The capacity of the granulator to process the plastic material depends on:
- The shape of the rotor
- The speed of the rotor
- The space of the grid
- The angle of the cutting blades
The cut flakes are washed to remove attachments such as glue, sand, paper, and grit. There is the application of continuous high-temperature water through the washing line over the plastic material.
The materials attached to the surface of the plastic material move in the process. Disinfectant agents and detergents are also used to ensure proper cleaning of the material.
At this stage, the flakes undergo separation treatments to eliminate potential contamination of the recycled plastics. The most separation process is based on the difference in the density of materials.
Some plastic recycling line also uses centrifugal force to separate material according to their weights. Other ways of separation are separation based on the ratio of surface area and separation based on melting point.
Pelletizing stage is the final stage in the operation of the plastic recycling line.
The pelletizing stage is where the plastics are converted to pellets for easy reuse, transportation, and other products' industrial manufacturing.
The machine uses screw extruders to process the flakes. The processing of the material here reclaims the waste plastic and convert it into pellets that are ready for other uses.
How to Set Up a Plastic Recycling Line
First, collect and analyse data. You want to understand what kind of plastic you currently use in the production cycles, and how it can be collected for recycling. Decide for yourself what you are going to do with recycled material: Will you use it in subsequent production cycles or will you sell it? It is also essential to investigate competitors who are few steps ahead and already started recycling. What do they do? Can their processes be improved?
Second, know your expenses. It is vital to know what quantities of plastic you need in order to keep your recycling processes economically feasible. To answer this question, consider costs associated with:
- Recycling equipment,
- Storage and\or recycling space,
- Salaries for employees,
- Collection process (including vehicles to deliver plastic waste).
Setting up a recycling line can be costly, so you want to make sure that you choose the best recycling equipment for your specific purposes, be it crushers, shredders, extrusion lines, blow molding or thermoforming lines. In short, the recycling process consists of the following stages: Sorting (manual, automatic or mixed), separation, granulation, washing, rinsing, drying and transforming flakes into pellets. There is no universal solution for every situation. Every recycling line is unique, so consult with a recycling machine manufacturer and decide on what combination of recycling machines will work for you.
Furthermore, consider if you have enough space to install the equipment. If not, you may want to rent or buy a spot to which vehicles have an easy access. Separating plastic from dirt or other types of garbage is an important step, so you also want to have a connection with a water treatment system and stable energy supply. Do not forget to make sure that your company has all the necessary documents (permits and licensing) and is ready for inspections.
Third, plan the collection process. Now you know how much plastic you need to make profit. Is it possible to collect this amount? If you collect plastic waste directly from consumers, establish good communication, install special recycling kiosks (like some major beverage companies do) or offer your costumers incentives for every used plastic item they bring back to you. Your company may also cooperate with volunteers or local centers for collection and disposal of plastic waste.
Tips To Improve Plastic Recycling Process Efficiency
Sorting recycling materials
The first essential stage in effective recycling is organizing plastic recycling materials according to their kinds and removing non-recyclable items from the material.
This could facilitate and aid in the ongoing recycling of plastic.
On the other hand, limiting humidity and contamination of plastic waste as much as you can can assist reduce material loss and improve the quality of the end pellet.
Use simple and easy to maintain machine design
Simple machine design, ease of operation, as well as upkeep, are all aspects that contribute to increased recycling efficiency.
Since these features enable operators to quickly learn how to operate the equipment efficiently and maintain the unit in good shape, this reduces operational expenditures.
Integrated machine structure
Several pieces of plastic recycling equipment perform crucial tasks during the recycling process.
For example, a cutter compactor lowers the size of the plastic waste, an extruder melts the items so that they can be reshaped, and finally, a pelletizer machine cuts the melted plastic into final pellet shapes.
These several pieces of machinery can be combined into a single plastic recycling machine thanks to a variety of user-friendly integrated machine designs.
By reducing operating phases, minimizing labor intervention, and saving time and energy, these integrations enable continuous operation.
Smart recycling solutions that are automated
Recycling automation not only saves personnel interaction but also allows for a quicker and more smooth recycling process.
In addition to the previously mentioned features, plastic recycling machines offer additional automation capabilities such as:
- Integration of third-party filter systems for further developed post-consumer recycling.
- Dual channel filter technique enables changing screens without having to restart the machine.
- Auto-adjustment of pelletizing blade speed and pressure for uniform pellet size and shape, resulting in no material loss.
- System of back-flush filters to perform automated melt waste discharge.
- Plc control framework with upgrade for executing a variety of jobs quickly, such as online troubleshooting, automated pre-heating, the optimization of parameters, and so on.
Plastic recycling line are comprehensive systems designed to efficiently process plastic waste, particularlybottles, and transform Them into valuable resources. These advanced recycling lines employ a series of interconnected processes, including sorting, crushing,Washing, and pelletizing, to ensure the highest quality recycled output.The primary function of plastic recycling line, such as bottle recycling lines, is to divert bottles from ending up in landfills or Incineration facilities. Instead, these lines enable the collection, sorting, and processing of bottles, initiating their journey towards a new life as recycled materials. By doing so, plastic recycling line contribute significantly to waste reduction and alleviate the strain on Already overwhelmed waste management systems.
The role of plastic recycling line, including bottle recycling lines and bottle washing lines, extends beyond waste reduction.These Systems also promote resource conservation and environmental preservation. By recycling bottles, the demand for virgin plastic Production decreases, alleviating the strain on natural resources, such as fossil fuels and petroleum. Additionally, plastic recycling line Contribute to energy conservation, as the production of recycled requires less energy compared to producing new plastic from raw Materials.
Moreover, the environmental benefits of plastic recycling line are substantial. By diverting pet bottles from landfills, these recycling lines help reduce greenhouse gas emissions associated with the decomposition of plastic waste. Additionally, they mitigate the pollution of ecosystems, including oceans and water bodies, as recycled materials reduce the likelihood of bottles ending up in these Sensitive environments.
Plastic recycling line also foster the circular economy. The recycled produced by these lines serves as a valuable resource for various Industries, including packaging, and textiles.
