The construction sector is one of the most resource-intensive in the world. It accounts for around 50% of all raw materials extracted, 35% of the waste generated in the EU and a significant share of carbon emissions. When a building is demolished, an enormous quantity of materials - steel, concrete, timber, glass - ends up in landfill, even though much of it could be reused.

The reason for this waste is simple: no one knows exactly what is inside the wall. What kind of concrete, what reinforcement, what insulation materials, whether they contain asbestos or other hazardous substances. The Digital Product Passport for construction products is the answer to this problem.

The Construction Products Regulation (CPR) and the DPP

The revised Construction Products Regulation (CPR) now includes DPP requirements for a range of building material categories. The goal is for every brick, window, beam or insulation panel placed on the EU market to carry its own digital passport with complete information on origin, chemical composition and end-of-life behaviour.

The Concept of a Building Material Passport

The individual DPPs of construction products come together in a larger concept - the Building Material Passport. This is a digital twin of the entire building that aggregates the passports of all the materials it contains. The benefits are revolutionary:

• During renovation: The owner knows exactly which materials are in the walls and whether they are compatible with new ones
• At sale: The buyer receives the full history of the building, including data on every renovation
• At demolition: Construction companies know exactly what they can recycle and at what price - the building becomes a material bank
• For insurers and banks: A more accurate assessment of value and risk

What does a DPP contain for a typical construction product?

Let us look at a specific example - a window with a PVC frame and an insulating glass unit:

• Manufacturer, date and production batch
• Chemical composition of the PVC - whether it contains phthalates, lead or cadmium (banned substances)
• U-value (thermal transmittance) - an official, verified test
• Recyclability class - what percentage of the material can be recycled and how
• Disassembly instructions - how to separate the glass from the frame for recycling
• Expected lifespan and maintenance recommendations

The challenges facing the construction sector

Across Europe, the sector faces a set of specific challenges - Bulgaria being a telling example:

• Ageing building stock: A vast portion of buildings were constructed during the socialist era with no documentation whatsoever of the materials used - retrospectively creating passports for them is a complex task
• Numerous small contractors: Unlike the manufacturing sector, construction relies on many small firms with low levels of digitalisation
• Imported materials without a DPP: Many construction materials arrive from Turkey, China or Ukraine - with no DPP documentation

Conclusion

The construction sector stands on the brink of a profound transformation. The building of the future is not merely a physical structure - it is a bank of materials whose value is digitally documented and accessible. For construction companies and building material manufacturers, investing in the DPP now means positioning themselves at the forefront of circular construction in Europe.
