Demolition
• using the gentlest way to demolish a building
• using low-noise construction machines which
are up to date with the latest technology
• not exceeding the legal maximum limit by
construction noiseFUTURE.FUTURE.

Demolition
If pollutants will be discovered during thedemolition or completely overlooked, it can haveserious consequences
• cost risk
• delays in the building process
• additional costs for disposal
• environmental risk

Concept of disposal
The concept has to contain following information:
• waste code/ waste identification
• Description of the nature and composition of
hazardous demolition material, including
analysis of results
• Waste collecting points/ component
• Estimated quantity of waste in tons
• Disposal methods

prerequisites to be able to recycle and re-use• before starting demolition, it has to be secured how to get best results of an unmixed demolition waste
reusable components will be dismantled
recycling-oriented deconstruction

problems of recycling
• the material properties deteriorate
„downcycling“
• irreversible material composites
increasing importance in
„energy-efficient construction“
of buildings

materials to re-use
sale of re-useable components:
• component exchanges (e.g.: www.bauteilnetz.de)
• classified advertisements
• scap metal dealers
also a free disposal can be useful to reduce
the demolition costs

recycling- and re-useable materialsin new buildings
• recycling-materials are especially used in infrastructural measures
increasing sense of responsibility of contracting authorities are necessary for reaching higher recycling rates!
Directive 2008/98/EC on waste
• basis for the national law of the EU Member States concerning the waste management
• requires that EU member states adopt it in their national law
• Intention: waste management without endangering human health and harming the environment
• Objective: 70% minimum recycling rates preparing for re-use, recycling and other recovery of construction and demolition waste

KrWG (Recycling management law)
• the German “answer” of the EU Directive
• modernized the existing German waste law and will become effective in June 2012
• Intention: - Increase the Recycling rate of construction & demolition waste - resource efficiency
- the waste hierarchy is applied

Other National laws & regulations
• KrWG is supplemented by a series of ordinances about guidelines & operating rules - Waste Catalogue
• Other National laws 1. Industrial Waste law - regulations about the disposal of industrial, construction & demolition waste 2. Regulation groundwater, alternative construction material, soil protection
• in addition to the federal law there are several regulations and administrative provisions of the seperate 16 states

• Finite resources of relentless domestic
construction minerals
• responsibility for sustainability in the next generation
•reduce the volume of waste and the closure
of material cycles
where it´s reasonable and possible.
