## Short answer
PVC pipes (polyvinyl chloride) are used for drainage installations, sewer pipes, and electrical conduit. They are inexpensive, smooth, and chemically resistant. PVC is controversial for environmental reasons: production involves chlorine gas and plasticisers (phthalates), and PVC is difficult to recycle. PE and PP pipes are more climate-friendly alternatives.
## Who it is relevant for
Homeowners, studios and agents researching material choices.
## What FT can prepare
- Summarise material properties, GWP, common uses, renovation relevance and alternatives.
## What the architect validates
- Whether the material fits the existing building, detail, durability, moisture and documentation needs.
## Key figures

| Metric | Value |
| --- | --- |
| GWP | 2.41 kg CO₂-eq/kg |
| Density | 1400 kg/m³ |
| Expected lifetime | 50+ years |
## Use

- Drainage pipes and sewer pipes
- Electrical conduit
- Gutters and downpipes
- Cooling water and drainage installations
## Renovation relevance
PVC drain pipes are standard in Danish construction from the 1960s–1990s. In renovation, it is recommended to switch to PP pipes for repairs and replacements. Electrical PVC conduit can be preserved.
## Comparison

| Material | GWP |
| --- | --- |
| PE pipes | 1.89 |
| PVC pipes | 2.41 |
| Copper pipes | 3.5 |
| Stainless steel pipes | 5.5 |
## FAQ
### Are PVC pipes dangerous?
The pipe in use is normally harmless. Problems arise during production (chlorine gas) and incineration (dioxin). PVC should not be burned — it must go to chemical waste or specialist PVC reception.
### What are alternatives to PVC drain pipes?
PP pipes (polypropylene) and PE pipes are alternatives to PVC drainage installations. They are easier to recycle and contain no chlorine compounds. PE is standard for water supply pipes.
### Can PVC be recycled?
PVC is technically recyclable but difficult in practice, as it is typically mixed with other materials and contains additives. The recycling rate for PVC building waste is low.
### When is PVC still the best choice?
PVC is difficult to replace in electrical conduit systems (flexible, chemically resistant) and certain drainage installations. For drain pipes, PP pipes are a direct alternative at roughly the same price.

## Uncertainty and boundaries
Material numbers depend on product, EPD, assembly, lifetime and project context.
## Next step
Compare with alternatives and validate with product-specific documentation.
