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

FUTURE.FUTURE.





Disposal

FUTURE.FUTURE.





recycle old material, to offer it as good as new raw material, is not only a vision of the environmental movement, but it’s already a technical advanced reality and economic necessity.

Concept of disposal

FUTURE.FUTURE.





material origin quantity Classifi-cation

prepara-tion

comment

concrete stairs, ceiling

3.800 t Z1.1 material to be screened

declaration

concrete workshop, floor

100 t Z2 material to be screened

declaration, removal

wood floor, roof 2,5 - 7 t A II container removal

plaster-board

walls 20 t A IV container removal

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

FUTURE.FUTURE.

LAWS & LAWS & REGULATIONS.REGULATIONS.




European guidelines

the confederation create guidelines about

recycling of construction materials.

The aims

• equivalent practice

• expanding of the guidelines

• common operating basics

FUTURE.FUTURE.





Categories for construction waste

• Hazardous demolition waste

• other hazardous waste

• Non-hazardous demolition waste

Recyclable construction waste• construction and demolition wood

• untreated wood

• treated wood

• cement

• bricksFUTURE.FUTURE.





non-recyclable construction waste

• asbestos cement

• contaminated rubble

• solvent-based paint

increased potential risk for humans and the

environment

FUTURE.FUTURE.





Places for Seperation

• 2748 Deponien in Gemany

• 39,1 Mio. t input per year

Disposal companies specialize in

certain materials

advantages of recycling and re-use

• saving natural ressources

• waste prevention

• energy saving

• CO2 reduction

FUTURE.FUTURE.





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

FUTURE.FUTURE.





problems of recycling

• the material properties deteriorate

„downcycling“

• irreversible material composites

increasing importance in

„energy-efficient construction“

of buildings

FUTURE.FUTURE.





materials to re-use

steel girders roofing tile pipelines

wooden beams sanitary facilities windows / doors

FUTURE.FUTURE.





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

FUTURE.FUTURE.





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

The 5-steps hierarchy

FUTURE.FUTURE.

LAWS. EU.LAWS. EU.




1. Prevention

2. Preparing for Re-use

3. Recycling

4. Recovery

5. Disposal

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

FUTURE.FUTURE.

LAWS. EU.LAWS. EU.




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

FUTURE.FUTURE.

LAWS. NATIONAL.LAWS. NATIONAL.




FUTURE.

• 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.
