Abstract: The production of construction and demolition waste in the Netherlands is about 15 million tonnes each year. There are three different ways of reusing: reusing the construction, the elements and recycling the material. Furthermore the materials can be recycled (reuse in the own cycle) and downcycled (reuse in another cycle). About 80-90% of this waste in the Netherlands is being reused, for the main part as a road base material. The policy of the Dutch government aims at reuse of this construction and demolition waste in its own cycle, at the highest possible level.
Therefor a flexible order for the treatment of construction and demolition waste is developed; the so-called Delft Ladder. This Delfi ladder is a toolbox with 2 different items. Firstly 10 blocks (the 10 reuse options), and secondly calculation models which can fix the order.
These methods are the Life Cycle Assessment-method, The Eco-cost Value Ratio and the a new developed Degradation Factor.
Controlled reuse of materials, on technical, economical en ecological aspects, over and over again becomes possible with these methods.
