Climate, sustainability and responsibility

Humans have an inherent desire to improve and simplify. Old methods are inexorably replaced by new ones, traditions and working methods are turned upside down. Industries are challenged and forced to change. And that can be hard!

If a method is more environmentally friendly, more advantageous economically, and has just as long a life expectancy as an older method, then why not adopt the new method?

For us, it is about taking responsibility here and now and doing the best we can for the future.

Lower costs up to 80% with Inpipe’s method

We all have limited resources and this should be enough. Suppose you need to replace 100 meters of sewage and stormwater pipes that are located four meters below street level. If you choose Inpipe liners and include everything — preparation, excavation, digging, transport of materials, new pipes, filling, restoring the surface, fuel consumption, time consumption and personnel — you can save up to 80% of the costs when compared to old excavation methods. Money that you can use to renovate more pipes.

We think that it is important to take responsibility in the here and now.

Reduce carbon dioxide emissions by 80%

Being climate-smart is more important than ever! When calculated according to the example above, carbon dioxide emissions can be reduced by about 28,000 kg* if you use Inpipe liners instead of digging, this translates into a cost reduction of about 80%. This is equal to the emissions of a new car** that is driven 220,000 km, or about 5.5 times around the globe. We believe that reducing environmentally hazardous emissions is taking responsibility for the future!

*According to calculations made with the NCC NoDig Climate Calculator
**According to the Swedish Transport Administration, the average emissions for a new car registered in Sweden in 2015 are 127 g CO²/km.

The environment and chemicals

Inpipe is constantly working to reduce the climate impact of our production, transport, and products. We strive to manufacture and deliver as environmentally friendly a product as possible. We achieve this by continuously setting goals to reduce emissions and environmental impact throughout the supply chain, from raw materials to finished installed product.

The manufacture of any kind of product affects the environment; it’s inevitable. Our goal is, as far as possible, to streamline production and reduce the climate impact of our products.

The product

Inpipe’s products consist of fiberglass, polyester, and foils.

We make our liner as thin and light as possible: this means less consumption of materials and lower emissions from manufacturing and transportation. We are constantly looking for ways to reduce our consumption of chemicals during production or replace them with more environmentally friendly alternatives.

Fiberglass: manufactured from a type of glass where, among other things, the use of so-called fluxes has been reduced, in order to also reduce environmentally hazardous emissions.

Polyester: used in liquid form. Polyester must contain a solvent, usually styrene. In our production, we have continuously reduced the use of and emissions from solvents. After several years of research and development, in the spring of 2021 we were able to release Inpipe Freeliner®, which is the world’s first fiberglass-reinforced polyester liner that is completely free of styrene and all forms of bisphenol.

Foil: the plastic foils used in the product are made from recyclable plastics.

“You wouldn’t drive 5.5 times around the world for nothing, right?”


We strive to coordinate all of our transportation, both when purchasing materials and delivering products, in order to reduce environmental impact.

Product installation

When an Inpipe liner is installed, the polyester is cured using UV light. This means that the styrene in the polyester binds and is consumed. A cured product contains less than 2% residual styrene. Emissions are minimal. If you also use Inpipe Freeliner®, the product does not contain styrene at all and, as a result, there is no risk of styrene leaching into nature and the environment.

Curing with UV light is very energy-efficient in comparison with, for example, curing with steam or hot water and no process water is formed that must be disposed of.

Inpipe’s environmental policy

Inpipe is located in Vilhelmina, in northern Sweden, in the heart of Southern Lapland.

We are surrounded by amazing nature and the natural environment, in what many call Europe’s last wilderness. Many of us who work at Inpipe live close to nature and understand that caring for it is entirely natural and very important!

Therefore, it is also natural for us to have a clear business focus on protecting the environment and nature. We have a clear environmental policy and cooperate closely with authorities and organizations on environmental issues.

Environmental policy

Our lowest level requirements are to follow the law and government directives. In addition, we constantly strive to reduce our environmental impact. Some examples are listed below:

  • We are continuously reducing our use of chemicals and solvents.
  • With our product Inpipe Freeliner®, we have completely removed styrene.
  • The polyester in Inpipe Freeliner® has biocontent, which reduces our consumption of fossil-based raw materials by up to 30%. Read more >
  • We co-deliver products as it is more efficient from a transport point of view and thus reduces CO emissions.
