Why are reusable steel kegs more sustainable than PET kegs?
Reusable stainless steel kegs have the lowest carbon footprint for beverages processed on tap.
PET kegs are often marketed as recyclable, but most "recyclable" products are not actually recyclable due to the limitations of waste disposal facilities. PET kegs (including bag-in-kegs) are made of several types of plastic, often fused together, and each type of plastic requires its own waste stream. The economic viability is low and the recycling costs outweigh the benefits.
With reusable steel kegs nothing needs to be thrown away. They are simply recycled at the end of the product's life, making them a true zero-waste packaging.
Only the steel we use is capable of perfectly preserving the quality of the beverage from the keg to the tap. It prevents light and oxygen from affecting the beverage and guarantees constant reliability of the dispensing systems.
Reusable steel kegs need to be cleaned, but today's keg washers ensure that more than 90% of the water used to clean the kegs and tanks is recycled with a closed water recovery system.
The production of PET kegs, on the other hand, is water-intensive and based on petrochimical products.
