Company’s sustainable transformation

Circular economy strategy, sustainable development and related trends

Given the characteristics of the manufacture of plastic products on the EU and Slovenian markets, our company seeks to contribute to the circular economy strategy, sustainable development and related trends.

As part of the public tender “Promotion of sustainable business strategic transformation and development of new business models in Slovenian companies for easier integration into global value chains”, STRAMEX PET d.o.o. is participating in two ways:

➣ A Company participation in the TPSMP Academy.

➣ B Implementation of the applied research and development project “Development of the technology of manufacturing bottles from 50-100% R-Pet and polylactic acid (PLA)”.

Stramex PET d.o.o. is a proud member of Zeleno omrežje Slovenije – Zelena Slovenija.


What is corporate sustainability?

Corporate sustainability originates from the concept of sustainable development, which stands for such environmental, social and economic development of the planet that will enable our posterity to have at least the same, if not better, quality of life. When this “macro” concept is translated into a “micro” concept, i.e. the corporate level, it means our company’s contribution to the sustainable development of the planet – how the company contributes to environmental, social and economic development through its operations.

r-PET in PLA

What is r-PET?

It is a material obtained by recycling PET bottles and plastic.

In collection centres, they first get separated from other materials that are also suitable for recycling. The bottles are compressed and packed (there are usually between 6,000 and 7,000 bottles in a single bale) and sent to special PET recycling facilities. There they get sorted and washed and their labels are removed. Steam and certain chemicals are used in these processes. With the help of infrared technology and waste sorting metal detectors and finally on the sorting belt workers perform a final check and eliminate everything that is not PET. This is where the sorting process ends. This is followed by the grinding of the material into flakes, which must be completely clean, or they won’t be suitable for processing into rPET. Air sorting and washing is used in the process. At the very end, they wash all the material once more and dry it, and only then does it move on to further processing. In case the material is not completely clean, the molten material is additionally filtered, which eliminates all insoluble parts. The product is plastic pellets, which are even more practical for transporting and processing, mainly due to the uniform size of the particles.

What is PLA?

Biopolymers can be obtained from many different raw materials. Stramex PET bottles are made from polylactic acid (PLA), which is made from corn starch. It is a 100% biodegradable plastic that is produced on the basis of carbohydrate fermentation processes.

An environmentally friendly solution for those who do not want to have their packaging made from plastic or oil.

Our products can be sorted and included in the recycling process, but such material is not suitable for disposal in a home compost bin.

Recyclable and biodegradable!

Natural polymers are biodegradable. This means that our products can be composted in accordance with DIN standard EN 13432 and meet the requirement for breaking down into biogenic materials within 90 days.

7% lighter than plastic! Reduction of CO2 during transport.


What is HOT-FILL?

HOT FILL is a very attractive and more cost-effective solution for food and beverage manufacturers whose sustainable goals include health care and healthy eating.

Hot Fill means hot filling – a process in which a product is heated to a temperature of 80°C – 95°C in order to remove harmful bacteria and micro-organisms that are part of the product’s natural process.

Lower preservatives content and an extended product life.

Given the increasing consumer demand for more natural products that do not contain a lot of chemical preservatives, artificial flavours and colours, hot fill offers manufacturers the opportunity to provide a product that preserves high levels of nutrients and fresh taste, while also extending the shelf life of the product stored at room temperature from 6 to 12 months.

Longer product life = Reduction in product waste
