Conclusion
Flanders 6 million inhabitants
Recycling ratio of 90% 11 million tons of recycled C&D waste
OVAM Public Waste Agency of Flanders Founded in 1981 Prepares legislation regarding waste management Has means such as:
Subsidy Tax Sensibilisation Industry engagement Etc. http://www.ovam.be
OVAM Project « environmentally responsible material
use and waste management of buildings » Transition to sustainable material use
Since July 2007 5 steps1. Eco friendly regulations2. Selective demolition3. Rise the recycling quality of aggregates4. High quality stones fraction re-use5. Close material life cycle of some C&D
waste streams in an efficient way
OVAM & international networks Cradle to cradle network
Austria, Hungary, Italy, The Netherlands, France, Finland, United Kingdom, Romania, Slovenia
Waste prevention & management Financed by European Union
Resource Efficiency Alliance Program of EPE ( European Partners of
Environment) Promote a low carbon and resource efficient economy
OVAM’s Materials Decree Only in Flanders (14th December 2011) Goal : decrease netto impact of the
waste cycle Environment Health
Sustainable material management Based on a 5 steps ladder
5 steps ladder material decree1. Prevention
Eco-design Ex: Ecolizer instrument
2. Preparation of re-use Controle, washing old material Back primair material Ex: Second hand shops
3. Recycling Closed the cyclic material circulation Ex: Wood as fuel
4. Other forms of application To generate energy Ex: Incenirator
5. Removal policy Flexibility to success
Other organizations VITO
Research center of clean technology OCW
Research center of road construction VLAREM
Flemisch regulations for the environment VLAREA
Flemish regulations relating to waste prevention and management

Demolition methods Selective demolition Recycling
Conclusion
Demolition
How does it work? Building waste
Stone fractionsConsists of: concrete rubble, masonry, a mixture of both, ceramic & natural stone
Non-stone fractionsConsists of: wood, plastics, scrap metal, paper and cardboard, waste gypsum, bituminous materials such as roofing, insulation, etc. Other residues (container waste)Sorting necessary for the different waste streams
Selective demolition Selective collection of different flows of waste Happens when buildings get demolished Waste
that gets collected separately is easier and/or cheaper to recycle
Use of recycled goods reduces the use of primary goods
Selective demolition is: Smart Ecologically viable Economically viable
Companies with selective demolition
Selective demolition Selective demolition is not yet
integrated (not yet sufficiently established) OVAM obligated the composition of a
demolition inventory Buildings with a volume over 1000 m³ Different function than accommodation
Selective demolition Recycling has different advantages
Saving raw materials Saving energy when producing products with recycled
materials Reduction of external dependence of raw materials Creation of new jobs (labor-intensive process)
Recycling process: Pollution of the recycled materials Quality loss Not always possible to use recycled material (low quality)
Concrete -> foundation materials Magazines -> toilet paper
Recycling ,(voorbeelden geven- concretiseren) Management system
Collecting and transport debris Acceptance debris Production recycled granules Transport recycled granules Use recycled granules
Recycling ( kan je iets zeggen over de reclycling van bouwmetarialen/ van materialen van gesloopte gebouwen) – collecting and transporting debris
Individuals Container parks Sorting companies Container services
Contractors Licensed establishments Waste identification forms
Recycling – Acceptance of debris
Acceptance and storeage on basis of Kind of debris Origin and composition Equipment processing plant
Certain streams of debris need seperate approval Debris from a fire Debris from soil remediation works Debris from the sieving of soils that do not meet VLAREBO Debris from the physicochemical cleaning.
Recycling – production of recycled granules
VLAREA ‘Flemish regulations relating to waste
prevention and management’
Unitary regulations
Environmental friendly quality Structural requirements Certification of recycled granules
Environmental license
Recycling – transportation of recycled granules
Delivery to location Delivery form provided by the certificate
holder The builder can not put the granules on the
market
Intermediate storage is prohibited For example on premises of the contractor or another licensed location
Recycling – use of recycled granules
Following applications are allowed Applications for which a harmonized European
framework exists Applications based on the standard specifications of
the Flemish region Mixing unit for hydraulically bound mixtures Applications as building material in a "work" based on the decree of 9 May 2008 laying down the list of architectural land-use of excavated soil (non-exhaustive list)
