The construction and property sector cause large emissions of greenhouse gases, which has raised the issue of demolition vs. renovation. We talk about circular buildings and circular construction. Circular construction can mean that instead of demolishing an old industrial building and building a new residential building next door, the industrial building is converted into a residential building. And if you âbuild newâ, you use, to some extent, old building parts â that is, recycling of building materials â provided that these are mechanically durable. This development is already being driven by forward-thinking property companies and brings considerable environmental benefits in the form of less waste, reduced greenhouse gas emissions and lower resource consumption.
However, it is common for already used materials to contain chemical and/or microbiological contaminants that risk spreading to the indoor air in the ânewâ building. The problem can be easily solved by covering the structure (indoors) with the cTrap fabric that captures the emissions. cTrap therefore offers a unique opportunity to ensure clean indoor air in circular construction, which is especially important if the ânewâ building is to house apartments, schools, daycare centers, nursing homes, etc.
