Good practices and investments related to Cleaner Production
Example No. 1
Optimization of plastic processing in the thermoforming process - closed raw material cycle
FAMED Żywiec sp. z o.o.
Industry branch: electrical machinery industry (manufacture of medical equipment)
Resources in question:
- Waste (plastic waste)
After thermoforming and removal of the protective film, the pieces of ABS plates are ground. A mill grinds them into granulate, which is used as a raw material for the injection moulding machine to make further manufactured elements. The plastic processing process operated in FAMED is an example of a process with a minimum amount of waste, in which the raw material is in a closed cycle (pieces of ABS plates are reused in the production process). Products made of secondary granules may be slightly less resistant to sunlight, but this does not prevent the production of internal components (e.g. connectors, sleeves, etc.).
Stages of a closed cycle in the process described above: thermoforming of ABS plates (picture in the upper left corner), cutting of moulded parts, grinding of ABS pieces, drying of granules, using granules for injection moulding

Obtained benefits and effects of the implementation:
- No waste generation - closed cycle of raw material (ABS plastics)
- Reduction of material consumption
