Regranulate production process

The process of creating regranulates from polypropylene (PP), high-density polyethylene (HDPE) and low-density polyethylene (LDPE) consists of several key steps that include collection, sorting, cleaning, milling and regranulation.

Collection of materials

The collection of raw materials is the first step in the recycling process. This involves gathering plastic waste from various sources.

We provide recycling services for packaging waste such as LDPE packaging film, household chemicals, and PP film.

Sorting

Sorting is a crucial stage, as different types of plastics must be separated to achieve a homogeneous regranulate. Sorting can be done manually or mechanically using advanced technologies, such as optical separators or spectral recognition systems.

Cleaning

The collected and sorted plastics must be thoroughly cleaned to remove contaminants such as food residues, labels, adhesives, or other substances. The cleaning process may involve water washing, chemical washing, and drying.

Grinding

The clean and sorted plastics are then ground into small particles. This process can be carried out using mills or crushers. The size of the grinding is adjusted according to the requirements of the final product.

Regranulation

The molten plastic is formed into pellets through the hot regranulation process: the melted material is pushed through a die and then cut into granules.

Cooling and drying

After granulation, the pellets must be cooled and dried to achieve a stable and uniform final product. the cooling process can be done using water or air.

Quality control

Our dedicated test laboratory carries out a range of tests to verify quality and continuous technical evaluation to ensure that the right product is received by the recipient.

Packaging and storage

Finally, the finished regranulates are packaged and stored. they can be packed in bags, big bags, or other containers, depending on the clients' requirements.

Summary

PP, HDPE, and LDPE regranulates are valuable secondary raw materials that can be reused in the production of new plastic products.

The recycling process is complex and requires advanced technology, but it offers significant environmental and economic benefits by reducing waste and conserving natural resources.
