Resource conscious pipe production

The LK Pex pipe manufacturing unit is located in Ulricehamn, Sweden, and was inaugurated in 2014. The factory has a total floor of 20 000 m² and consists of the production area, a large central warehouse, laboratories and offices for administration. When we took the decision to build an entirely new factory, it was important to ensure not only an increased capacity but also that the project would be undertaken in a sustainable way. It was very clear to us that the new premises and production had to be efficient economically, environmentally and in terms of energy usage. We are very proud to be able to deliver pipes that are not only of a high quality but also produced in an energy efficient way.

A closed system for cooling water in the new factory has made a significant reduction in water consumption of the pipe production lines compared to the old factory. We have reduced our energy consumption by upgrading our production machinery to more energy efficient units, but also by using motion activated LED based lighting technology in the factory. Our ambition is to increase our purchases of electricity from sustainable sources on an annual basis and reduce our fossile sourced electricity needs.

Waste heat becomes green energy 

Both the pipe production and the logistics centre are self-supporting for heating, thanks to recovery of excess heat from the pipe production lines. Heat exchangers are installed to recycle the waste heat from the production process.

In addition to providing heating for the factory and logistics centre, the excess heat is used in a snow melting system at the loading docks and as district heating in the municipality of Ulricehamn.

Environmental Product Declaration

Environmental Product Declaration

An EPD is an environmental product declaration that describes the product's environmental impact throughout its entire life cycle. An EPD includes product sheets, process descriptions, methodological choices for the life cycle assessment, and results of the environmental impact.

Keeping track of pellets

LK Pex has signed up the Operation Clean Sweep® (OCS) pledge in Europe and is implementing zero pellet loss measures in our operations. OCS is an international programme designed to prevent the loss of plastic granules (pellets, flakes and powders) in the value chain. Our commitment as a manufacturer of plastics pipes is to ensure that the raw materials we handle are always contained and do not spread to the environment.

Fossil-free electricity

Starting from January 1st, 2024, we have transitioned to 100% fossil-free electricity in all properties owned by LK. By using fossil-free electricity, we reduce our CO2 footprint, which in turn assists us in our sustainability efforts. For instance, we achieve lower values on our EPDs.We are continually searching for new areas where we can enhance our environmental impact. Lowering our CO2 footprint is a crucial part of this endeavor, and we are committed to making a difference.
