Energy neutral

Practice what you preach. Therefore Leadax has the most sustainable production process possible. For example, the production facility is energy neutral as the entire roof is covered with solar panels. Leadax also uses bicycles to go back and forth in the plant. Also there is an efficient system for using packaging material. Besides reducing large amounts of waste as raw material for the product, the production process itself is designed to be fully sustainable.

Leadax creates building materials with a future, not of the future

Polyvinyl butyral (PVB) is the plastic foil in safety glass which could not be reused, until now. There is an abundance of PVB waste available worldwide. In Europe alone, 1.5 billion kilograms of PVB waste are added to this enormous pile of plastic waste. Every year. For comparison: This is the weight of 150 Eiffel towers. Besides that, current products for waterproofing buildings are not sustainable, have a large carbon footprint and are (often) toxic. If we want to reach the Sustainable Development Goals of the United Nations in creating a sustainable environment, this problem has to be solved.
