wood

Wood is one of the easier materials to recycle from construction waste. Once all contaminants are removed from the wood fraction, the wood can be reused for furniture or building materials if the wood is unpainted. Alternatively, it can be recycled for energy recovery by burning it in, for example, a heating plant.

Plastic

Plastics contained in mixed construction waste can now be separated by simply blowing away the plastic with a wind shifter. Purified plastic streams are generally difficult to recycle, so they usually go on to energy recovery. At the same time, a separated plastic waste can make the rest of the waste possible to recycle.

Concrete

Recycling of concrete is an area where technology is developing and where we at Norditek have an ongoing test project right now. Concrete waste can come from houses to be demolished or waste from the concrete industry. Residual materials from industrial processes can be recycled as aggregates or as additives in new concrete. The latter is what we are currently developing.

Metal

Metals in a construction waste can be separated with magnets and eddy current magnets, depending on whether they are magnetic or non-magnetic. With the very powerful eddy current magnets we use, it is now possible to separate even small particles of non-magnetic metals. Metal can be recycled almost any number of times.

Waste material

When talking about the recycling of construction waste, one can also include waste materials from new construction. Waste material can either be reused or, as in the case of plasterboard waste, the material can be put back into new construction. 

These were some examples of materials that can be recycled from construction waste.
