Protection of natural environment is effected on many levels at CP Glass S.A. and focuses on:
- reduction of waste after production,
- development of packaging waste recycling system,
- reduction of energy consumption,
- reduction of water consumption,
- reduction of emission of greenhouse gases,
- reduction of noise emitted by production installations.
Production of glass packgagings at CP Glass S.A. is aimed at maximization of productivity and reduction of waste amounts after production at the same time. Manufacture of glass packagings is neutral to the environment, however it still generates some types of waste including cullet after production and small amount of other waste such are non-toxic technological dusts, hydraulic oils, used packagings after raw materials (paper and cardboard).
The main production waste is cullet. It is generated from defective packagings that did not pass quality control at final stages of the production process. Although as a result of modernization of technological lines in 2005 – 2007 amounts of defective packagings were significantly limited, our ambition to meet high expectations of our customers results in a certain amount of bottles being broken and sent back, as a raw material, to the glass furnace where it is melted again. The cullet circulation is a closed process that allows to recycle the waste in 100% within the plant.
The utilization of big amounts of cullet as a component of a batch gives significant savings in energy consumption because the temperature of melting a batch containing cullet is lower than the temperature of melting a batch composed only from mineral raw materials. Due to lower temperature of batch melting, smaller amounts of gas are burnt, which in turns results in reducing the emission of greenhouse gases. It is worth indicating that in 2006 and 2007 CP Glass S.A. had the industry’s lowest emissivity indexes i.e. amounts of emitted greenhouse gases per ton of melted glass, which is especially important nowadays when we face the threat of greenhouse effect and when global attempts are made to limit CO2 emission.
To sum up, the holistic approach to environmental protection issues at CP Glass S.A. resulted in removing 27.000 tones of waste from the market, energy savings were obtained and the emission of greenhouse gases was reduced by about 3,500 tons (compared to the amounts emitted when the business-as-usual policy is applied – according to the methodology used by KASHUE).
