  3. Table of content • Introduction • Flanders • OVAM and laws • Other organisations • Demolitionmethods • Selectivedemolition • Recycling • Conclusion

  4. 6 million inhabitants • Recycling ratio of 90% • 11 million tons of recycledC&D waste Flanders

  5. OVAM • Public Waste Agency of Flanders • Founded in 1981 • Prepareslegislationregardingwaste management • Has meanssuch as: • Subsidy • Tax • Sensibilisation • Industry engagement • Etc. • http://www.ovam.be

  6. OVAM • Project «  environmentallyresponsiblematerial use and waste management of buildings  » • Transition to sustainablematerial use • Since July 2007 5 steps • Eco friendlyregulations • Selectivedemolition • Rise the recyclingquality of aggregates • High quality stones fraction re-use • Close material life cycle of some C&D wastestreams in an efficient way

  7. OVAM & international networks • Cradle to cradle network • Austria, Hungary, Italy, The Netherlands, France, Finland, United Kingdom, Romania, Slovenia • Wasteprevention & management • Financed by European Union • Resource EfficiencyAlliance • Program of EPE ( EuropeanPartners of Environment) • Promote a low carbon and resource efficient economy

  8. OVAM’sMaterialsDecree • Only in Flanders (14th December2011) • Goal : decreasenetto impact of the waste cycle • Environment • Health • Sustainablematerialmanagement • Based on a 5 stepsladder

  9. 5 stepsladdermaterialdecree • Prevention • Eco-design • Ex: Ecolizer instrument • Preparation of re-use • Controle, washingoldmaterial • Back primairmaterial • Ex: Second hand shops • Recycling • Closed the cyclicmaterial circulation • Ex: Wood as fuel • Otherforms of application • To generateenergy • Ex: Incenirator • Removalpolicy • Flexibility to success

  10. Otherorganizations • VITO • Research center of clean technology • OCW • Research center of road construction • VLAREM • Flemischregulations for the environment • VLAREA • Flemish regulations relating to waste prevention and management

  12. Demolition

  13. How doesitwork? • Building waste • Stone fractions Consists of: concrete rubble, masonry, a mixture of both, ceramic & natural stone • Non-stone fractions Consists of: wood, plastics, scrap metal, paper and cardboard, waste gypsum, bituminous materials such as roofing, insulation, etc. • Otherresidues(container waste) Sortingnecessaryfor the different waste streams

  14. Selectivedemolition • 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

  15. Companieswithselectivedemolition

  16. Selectivedemolition • Selective demolition is not yet integrated (not yetsufficientlyestablished) • OVAM obligated the composition of a demolition inventory • Buildings with a volume over 1000 m³ • Different function than accommodation

  17. Selectivedemolition • 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

  18. Recycling ,(voorbeeldengeven- concretiseren) • Management system • Collecting and transport debris • Acceptance debris • Production recycled granules • Transport recycled granules • Use recycled granules

  19. Recycling ( kan je ietszeggen over de reclycling van bouwmetarialen/ van materialen van geslooptegebouwen) – collecting and transporting debris • Individuals • Container parks • Sorting companies • Container services • Contractors • Licensed establishments • Waste identification forms

  20. 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.

  21. 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

  22. 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

  23. 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)
