Recycled insulation that saves space
We have created unique results with the recovery of the surplus material from production and can now cast insulation materials with 45% regenerated. Regenerate in the form of hardened PUR, where we recover the production waste and thereby contribute to a more sustainable production.
In the past, it has been associated with very large technical challenges to recover rigid polyurethane foam in a way where the material's most important technical properties are preserved. Industrial recovery of PUR has been minimal and success stories from the industry have been about recycling 2-10 % of the production waste.
Our success with upcycling is the result of an intensive development process, where reducing residual products and giving new life to waste has been the primary objective. In the process, we have worked with 2 methods, which have given good results. The one technology is now ready to be implemented in production and deliver greener insulation. With the latest results, it has thus been possible to cast products with a high degree of recycling, which at the same time have fully equivalent insulation value and material properties as ordinary molded PUR.
From waste to technical insulation
In the green transition, there has been an increased focus on the importance of insulating technical installations. It costs energy to heat up liquids and correspondingly to cool them down. Effective insulation of the piping is therefore an important ingredient in the recipe for more sustainable production and operation.
Pipe insulation in cell foam in the form of PUR and PIR has a formidable insulating capacity and a long life, as it does not absorb moisture or collapse. When using PUR and PIR insulation, the loss of heat and cold is reduced far more effectively than with classic insulation types, which saves the world from unnecessary CO2 emissions.

Polyurethane products
Work with polyurethane foam
Rigid polyurethane foam (PUR foam) is a thermosetting plastic known for its safe handling and use. This material has a number of advantages that make it a popular choice in various industrial and construction applications. One of the most notable features of rigid PUR foam is its ease of handling. It can be easily cut, shaped and adapted to different applications without the need for advanced equipment or technical skills. This makes it suitable for DIY projects as well as professional applications.
PUR foam is also known for its low weight in relation to its strength and insulation properties. This makes it easy to transport and install, while providing excellent insulation, making it ideal for insulating walls, ceilings, floors in buildings, as well as pipes and technical installations.
Another important advantage of rigid PUR foam is its resistance to moisture and mold growth. This makes it a reliable choice in wet rooms and other environments where humidity can be a concern.
Finally, PUR foam is known for its energy efficiency. It provides excellent thermal insulation, which helps to reduce energy consumption and maintain comfortable temperatures indoors. This makes it a greener choice, as it can help reduce energy consumption and CO2 emissions.
Overall, rigid polyurethane foam is a versatile and reliable material that combines ease of handling, strength, insulation and durability. It is a favorite in the building and construction industry and provides an effective solution for a wide range of applications.
Safety when foaming polyurethane foam
Working with ready-made foam does not require any special safety measures. The situation is different if the work consists of foaming polyurethane, i.e. produce polyurethane foam by mixing the raw materials isocyanate and polyol.
From August 24th 2023, appropriate training will be required before industrial or commercial use of products containing more than 0.1% by weight of isocyanates.
Only persons who have undergone special training may work with polyurethane foaming. The education is available at institutions for vocational education, e.g. AMU centers and technical schools.
Employers or self-employed persons who use the products themselves or weld must also have undergone the training before starting work. Everyone who works with isocyanate must undergo a two-day course. In addition, all employees who work with isocyanates in a way that may involve an increased risk of being exposed to the substance must in future complete a new AMU course on personal safety. The course has a duration of 1 day.
