We are leading the way in research and low environmental impact technologies
in the cosmetics packaging sector
The need to safeguard the natural equilibrium of the environment is of increasing relevance to the manufacturing industry and the cosmetics packaging sector in particular. Markets are extremely keen to reward the use of technologies and materials with low environmental footprints.
For Pibiplast, these aspects are of crucial importance. Demonstrating the great importance it attributes to the environment, in the past year the company has carried out ongoing research into raw materials, developing new biodegradable and regenerable products.
Bottles in renewable material
Pibiplast is delighted to present bottles produced using raw materials from renewable sources. The challenge consisted in finding a way to use BIO-BASED materials with existing moulds, without making any modifications and with the possibility of continuing to use the moulds also with the petroleum-based materials normally used.
What does “renewable raw material” mean?
A renewable raw material is one that can be produced or generated quickly. Sugarcane, for example, is a renewable raw material since it can be grown and then grown back naturally with the cycle of the seasons. Plastics derived from sugarcane, like other plant-based plastics, are therefore called “renewable” or “bio-based”.
How to measure the renewables content
Generally, the unit of measurement adopted is the BCC, which stands for Biobased Carbon Content. The higher the percentage of BCC in a polymer, the greater the reduction in CO2 emissions.
The benefits of renewable plastics
- They reduce our reliance on the use of a finite raw material such as petroleum
- They help reduce CO2 emissions.
The materials currently available:
- Green PE is a bio-based polyethylene available in LDPE, LLDPE, and HDPE versions.
- Chemically speaking, it is a polyethylene so it has the same mechanical and physical properties (barrier, heat resistance…) as a petroleum-based PE.
- Green PE can be mixed with petroleum-based PE.
- Bioplastic PE can be recycled along with petroleum-based PE.
- It is used for the production of bottles and tubes.
- Petroleum-based PET is composed of 30% hydrocarbons (Ethanol) and 70% terephthalic acid.
- 100% plant-based PET does not yet exist: indeed, while ethanol can be substituted with a renewable component, petroleum-derived terephthalic acid cannot be replaced. The result is a PET that is 30% bio-based.
- The BCC of Green PET is therefore lower than that of PE, corresponding to 20% overall while also guaranteeing a 30% reduction in CO2 emissions.
- From a mechanical and aesthetic point of view, Green PET offers the same characteristics as PET.
Pibiplast uses bottles made from R-PET, namely PET obtained from the regeneration of recycled PET bottles.
The base material is derived exclusively from post-consumer bottles and industrial waste from PET bottles.
Recycling PET bottles for new products contributes significantly to the reduction of CO2 emissions.
For this project, Pibiplast chose high-quality regranulated PET, certified to food-grade standard.
Bottle to Bottle
Used PET bottles are taken by consumers to a waste recycling point and subsequently undergo a specific recycling process.
- Automatic disposal.
- Automatic removal of labels and sorting of colours.
- Granulation, washing and decantation procedure, after which the various sized granules are separated.
Regranulated PET can be personalised with solid colour or transparent masterbatches.
Finally, it can be used for the production of other bottles.
R-PE used by Pibiplast is based on the same process of plastic bottles post-consumer recycling, but not only. Pibiplast has in fact implemented a virtuous cycle at its internal, by recycling the bottles wasted inside of its own production process. The same as R-PET, also R-PE keeps the same technical performances of vergin PE, ensuring its optimal use on standard EBM machines and molds. Bottles produced in R-PE appear opaque grey, becoming very different from the ones produced in vergin raw material. For this reason, to make them more appealing, it’s generally suggested the use of colorant and/or the personalization through decoration.
