Background

The process for recovering plastic wastes comprises of the following steps: sorting, crushing, washing, drying and pelletizing. Sorting is the CRITICAL step. Plastic wastes must be sorted according to type.  Since crushing, washing, and pelletizing are different for each category.  For example, HDPE is hard to tell apart from PP, but these plastics do not mix therefore can ruin an entire batch.

Since the recovery of the investment in Waste Plastic Recycling Plant is very rapid, this industry is growing very rapidly all over the world. The process for recovering plastic wastes comprises the following five main steps: sorting, crushing, washing, dehydrating and drying flake and pelletizing. Among which, sorting is the critical step.

Plastic wastes must be sorted according to soft (ABS, HIPS, PC, AS ,PP, Acrylic), mild(PVC) and hard material(PET) since crushing, washing, and pelletizing are different for each category. The higher the homogeneity of the sorted recycle2plastic waste is, the better it is for subsequent steps. For example, PVC bottles are hard to tell apart form PET bottles, but one stray PVC bottle in a melt of 10,000 PET bottles can ruin the entire batch. It is understandable why purchasers of recycled plastic want to make sure that the plastic is sorted properly.

Waste plastic is valuable. It is important for the future of our environment that waste plastic is diverted from landfills. Recycling a single plastic bottle conserves enough energy to light a 60W light bulb for up 6 hour.

We can all make a big contribution to protecting the environment.

After collection, the plastic bottles are returned to our sorting facility where the bottles are sorted by colour as well as the following polymer types:

  • High Density Polyethylene (HDPE).
  • Low Density Polyethylene (LDPE).
  • Polyethylene Terephthalate(PET).

After sorting, the bottles are granulated into small flakes, which are then put through a washing process which removes all contaminants such as, food residues, labels, glue, and any other contaminants. After washing and drying, the flakes are used as follows:

  • BW rHDPE White: repelletized and used in the manufacture of coloured plastic product such as wheelie bins, crates and drums.
  • BW rHDPE Mix: repelletized and used to produce black materials for use in application such as drainage pipe manufacturing and the moulding of automotive components.
  • BW rLDPE Clear/Smokey/Mix: repelletized and used to produce blow-moulded plastic packaging.
  • BW rPET: extruded back intro rolls of sheet which are then thermoformed into new trays for packaging. It is also used to produce fibres for the textile industry.
