Shout it from the rooftops
Environmental protection is no longer an option, but a reality for everyone. a sector that has been using natural raw materials for decades, which are also limited, must be fully aware of this. Derbigum has been aware of this for a long time – and without compromise. We are attentive to the changes in our world and actively seek timely responses. Our willingness to move forward drives us even more towards the creativity and quest for innovation that drive our company. Derbigum decided very early to embark on a new path of its own, in response to its concern for sustainability and respect for nature.
The best way to achieve this and reduce our carbon footprint consists of extending the life of our products as much as possible and recycling the bitumen into a new raw material.
We stand out in each of these two strategies. Derbigum is a pioneer in bitumen recycling. At first glance, bitumen and ecology seem difficult to reconcile. and yet, while it is true that bitumen is derived from oil, it is also the most environmentally friendly waterproofing solution for flat roofs, not least because of their impressive lifespan. Derbigum’s waterproofing membranes have, in fact, a proven minimum 40-year life span on roofs. Afterwards, they may easily receive a new layer of Derbigum. And there they go for another 40 years, no worries. What’s more, the membranes are 100% recyclable into high-quality raw material for the manufacture of new waterproofing membranes. From this recycled material we have developed Derbigum NT.
Derbigum therefore demonstrates on a daily basis that sustainable and global growth is perfectly possible. Thanks to our know-how and experience in roofing recycling, we are today at the forefront of ecological commitment and innovation. Since we use raw materials that are subject to depletion, it is our duty to transform them into a product that is guaranteed to last a long time and can then be returned 100% to the production process.
That is why we remain optimistic despite the bleak climate outlook. it’s quite simple: the more the consequences of climate change become apparent, the more innovation will be required to deal with them. At Derbigum, we therefore want, more than ever, to maintain our role as a pioneer at the forefront.

Recycling process
Derbigum demonstrates this, day after day, thanks to a unique and differentiating recycling program, which dates back to 1990. Derbigum thus assumes its environmental and social responsibility and stands as champion of the circular economy.

Back to the future
Since the 1990s, imperbel has been involved in the recycling of bituminous roofing membranes that have reached the end of their service life. The developed process generates a completely new raw material, Derbitumen.

Derbigum NT = Sustainable membrane
Recycling allows the introduction of DERBITUMEN into selected DERBIGUM product mixes
- Developed with Imperbel’s know-how
- Derbigum NT: 25% of recycled material
- Derbicoat NT: 30% of recycled material
- Reinforcements partly composed by recycled raw materials (glass fibers and non-woven polyester)
- Produced with 100% green electricity (2750 tons CO2 emission avoided in 2018).
- 100% recyclable at the end of its life. Can be integrated into the No Roof To Waste program.

The most sustainable waterproofing
The Dutch Institute for Building Biology and Ecology, NIBE, examined as an independent research organization the life cycle analysis of the Derbigum membrane and came with a remarkable result.
