Construction waste
The amount and composition of construction and demolition waste varies considerably at different construction sites and different phases. With good planning and implementation, recycling can be increased. By the year 2020, at least 70% of home construction and demolition waste should be recycled.

Always observe local and collection point specific instructions! The following are some general guidelines based on prevailing practices.
Yes
The following waste fractions must be collected separately at the construction site when technically and economically feasible
- concrete, brick, mineral tile and ceramic waste
- gypsum waste
- non-impregnated wood waste
- metal waste
- glass waste
- plastic waste
- paper and cardboard waste
- soil and rock material waste
In addition, hazardous waste needs to always be kept separate from other waste and material
Remember
The sorting obligation can be fulfilled either by sorting and separate collection of construction waste or by providing mixed construction waste to be sorted by a treatment plant.
However, hazardous waste and considerable amounts of gypsum waste must be separated already at the source.
Usually it makes sense to correct for example metal, concrete and wood waste separately from other construction waste.
Collecting and transportation
Especially at larger construction sites, waste is sorted into different waste types. The sorted or mixed waste is then delivered to collection points where they are either treated for utilisation or forwarded to appropriate treatment. By sorting different factions you get a financial saving and the waste can be utilised as raw material
Construction waste is transported from collection points to treatment plants, if necessary. Concrete and brick waste can also be processed at the collection point and clean surplus soil can be sent directly to be used.
Handling
At a treatment plant, construction waste is separated into different materials, stored and delivered to recycling or further treatment.
Recycling and recovery
Waste that can be recycled should be separated already at the source i.e. the construction or demolition site.
Crushing manufactured and quality controlled concrete and bricks yields material that can be utilised in earthworks, such as in the structural layers of road and field construction. Clean surplus soil can be utilised in terracing, filling and landscaping.
Most wood waste is used for energy production. Pallets are recycled and mould materials are reused as much as possible. Wood waste can be used for example as raw material for composite materials.
A treatment plant utilising a good separation process can capture 85–90% of all waste for recycling and energy utilisation.
Responsible organizers
When applying for a construction permit, the constructor is required to clarify the amount and type of waste produced and the sorting methods. Construction and demolition waste is the responsibility of the constructor or, if so agreed, the main contractor. As the waste holder, they are also responsible for each waste type getting transported to the appropriate collection point.
