Recycled Granules
Recycled granules refer to small plastic pellets that are produced from the recycling of used plastic materials. This process involves collecting, sorting, shredding, washing, melting, and reshaping the plastic materials, resulting in the production of new granules that can be reused in various industries. In the following sections, I will provide more detailed explanations about the production process, benefits, types, and applications of recycled granules.
Recycled Granule Production Process
The production process of recycled granules is carried out as follows:
- Collection and Sorting: First, used plastic materials are collected and sorted from various sources, such as bottles, bags, industrial parts, etc. These materials are then separated based on the type of plastic (such as polyethylene, polypropylene, polystyrene, etc.).
- Shredding: The sorted materials are shredded into smaller pieces to make them easier to use in the subsequent stages of the process.
- Washing: The shredded pieces are washed to remove impurities, fats, oils, and other contaminants.
- Melting and Extrusion: The clean and shredded plastic materials are melted at high temperatures and then extruded through an extrusion machine to form thin strands.
- Cutting and Granulating: The molten plastic strands are quickly cooled and then cut into small pieces (granules).
Benefits of Recycled Granules
- Environmental Protection: Recycling plastic and producing recycled granule helps reduce the volume of plastic waste in the environment and prevents water and soil pollution.
- Conservation of Natural Resources: Using recycled granules instead of virgin raw materials (like crude oil) helps reduce the consumption of natural resources.
- Cost Reduction: Producing recycled granules is usually cheaper than producing new plastic materials, so using them can reduce production costs.
- Energy Savings: The recycling process requires less energy compared to producing new plastic.
Types of Recycled Granules Recycled granules come in various types depending on the plastic from which they are made:
- Polyethylene (PE) Granules: These granules are produced from recycling plastics like plastic bags, bottles, and pipes.
- Polypropylene (PP) Granules: These granules are made from recycling materials such as packaging containers, household appliances, and automotive parts.
- Polystyrene (PS) Granules: These granules are produced from recycling items like disposable containers and protective packaging.
- Polyvinyl Chloride (PVC) Granules: These granule is made from recycling materials like water pipes and window profiles.
Applications of Recycled Granules
Recycled granules have diverse and customizable properties, making them widely used in various industries. Below are some of the most important applications of this material:

However, the growing adoption of recycled granule is part of the global movement towards sustainability and reducing environmental impact.
Frequently Asked Questions
- Are recycled granule comparable in quality to virgin materials? Recycled granule may sometimes have slightly lower quality compared to virgin materials, especially in applications requiring high strength or precise specifications. However, with advancements in technology, the quality of recycled granule has improved, and they can often be a suitable alternative to virgin materials.
- What types of plastics are used to produce recycled granule? Recycled granule is typically made from commonly used plastics such as polyethylene (PE), polypropylene (PP), polyethylene terephthalate (PET), and polystyrene (PS).
- Are products made from recycled granule recyclable? Yes, products made from recycled granule can also be recycled. This process helps reduce plastic waste and improve the recycling cycle.
- Is it possible to use recycled granule in all industries? Recycled granules are widely used in industries such as packaging, automotive, construction, household appliances, and textiles. However, in industries requiring materials with very specific properties, the use of recycled granules may be limited.
- What impact do recycled granule have on the environment? Using recycled granule has positive environmental impacts, including reducing plastic waste, decreasing the need for new raw materials, and lowering energy and water consumption in manufacturing processes.
- Can recycled granule be used in their raw form? Recycled granule is typically used directly in the production processes of new plastic products. They are either added to other materials or used on their own in machinery to manufacture plastic items.
- Is the cost of recycled granule lower than virgin materials? Yes, the cost of recycled granule is generally lower than that of virgin materials, as the expenses related to extraction, processing, and production of virgin raw materials are higher.
