HardGrey Metals Ltd., Sofia city, carries out buying of plastic waste which is processed to regranulate for reuse.

We buy and recycle the following types of waste plastics:

  • - HDPE - bottles, containers of cleaners, tubes, fuel tanks, drums;
  • - LDPE – stretch film, bags, nylon;
  • - PP - boxes, flower pots, basins, buckets, chairs and tables.
We supply different quantities of ready granulate of polypropylene and polyethylene to small and large factories.

The manufacturing process comprises the following steps:

  1. Retail and wholesale buying of plastic waste of low pressure polyethylene (HDPE) and polypropylene (PP).
  2. Sorting by material and color and mechanical removal of unnecessary impurities (labels, adhesives, etc.)
  3. Shredding (rough grinding) of plastic material through a mill.
  4. Laundering of raw material and passing successively through different phases before regranulation (washing, fractionation, sintering).
  5. Granulation of material – performed by extrusion line. The agglomerated material is heated up to a certain temperature. The molten material is cut to small granules.

Thus the recycled plastic granulate is ready for reuse.
