Recycling of Construction and Demolition waste Situation in the
Netherlands Peter Broere BRBS Recycling EQAR May 8th 2015 Contents
Focus on stony waste Background Netherlands Legislation
Private regulations Applications Conclusions Association for
recycling companies
Founded 1980 (35 years) C&D waste recycling Breaking and
sorting 70 members /> 100 sites 7075% of Dutch market volume
Member of FIR Background Densely populated Geotechnical situation
Natural recourses
Nl 395/km2; Au 98/km2; D 231/km2; Fr 100/km2 Spain 91/km2
Consequences for building and demolishing activity Geotechnical
situation 1/3 part polders (clay on sand) Peaty soils Sand Natural
recourses Gravel: Northsea and riverbeds No rock / mining /
mountains Recycling: 20 Mton = 99% Use: 150 Mton minerals
Development of Recycling in NL
1970s: Need for materials 1980s: Environmental awareness 1990s:
Quality management 2004+: European regulations Legislation Landfill
ban Environmental management law
No disposal of reusable C&D wastes Sets basis for economically
beneficial recycling Environmental management law Waste to be
discarded at licensed site Use of waste only allowed if regulated
in decree (e.g. soils and stony materials if complied to SQD)
Licences in the supply chain Demolition: duty to sanitize asbestos
Demolition: duty to separate specific wastes C&D waste
recycling: Only to process allowed wastes (Eural) C&D waste
recycling: No hazardous wastes (Eural) National waste plan
Prohibition for mixing wastes of different quality Policy rules on
waste streams (basis for licences) Supply chain Legislation Waste
Frame Directive Construction Products Directive
Declaration of performance CE marking for recycled aggregates: end
products placed in the European market requirements and
Classification (national implementation standards) Legislation Soil
Quality Decree (SQD) Product decree asbestos
Regulation on emissions of building materials (eluation and
composition) end quality leading for total supply chain use and
recycling benefit from SQD same level as for primary materials:
fair system costs are acceptable minimized double testing within
supply chain statistical system focuses on to critical parameters
complexity is manageable Product decree asbestos Partly implemented
in the SQD Other (radiation, outdoor air quality, etc.) New topics
or acceptable levels? Not specifically product related Legislation
End of Waste regulation (02-2015): Voluntary system
Definitions, Acceptance policy, Processrequirements, Product
requirements, Quality system level, Conformity declaration
Codification of CE + SQD Other requirements National Standard
Requirements Certification
CROW Standard Requirements (private) Civil engineering works
Important basis for contracts National Standards Applications e.g.
in concrete Certification private system for product quality
management of production testing quality level of sampling quality
level of tests statistical evaluation covers environmental and
technical aspects also covers legislation aspects Products From
sorting and breaking materials from construction:
Mixed Concrete Masonry Asphalt Fine Sieve sand Recycling breaker
sand Other Bound and unbound Characterisation Grading, shape, LA,
etc. (EN 13242/EN 13285)
Composition (EN A1): Concrete + masonry > 90% in different
percentages Mixed aggregate > 45% concrete Concrete aggregate
> 80% concrete Primary stone: < 10% Other stony: < 10%
Asphalt < 5% Contaminants: < 1% and 0,1% for organic
contaminants Bearing capacity: CBR (EN Annex D) Base layer

footpaths Paving layer (recycled sand) Pile mattresses (0/40 0/90
mm) Fills and embankments Applications Aggregates for Concrete (EN
12620) Concrete mortars
Concrete products Up to 100% replacement of primary materials Fines
included Up to 50% concrete aggregate without redesign of mixture
Up to 30% use of recycled aggregate allowed without notification Up
to C35/45 (EN 206) = 65 N/mm2 Applications Asphalt (EN 13108)
Reclaimed asphalt for warm asphalt
Reclaimed asphalt for unbound base layers Reclaimed asphalt for
cement bound layers Applications Other: Drainage - infiltration
Dikes all components
Riverbanks, shores Fillers Clay / Chamotte Gabion or Pannier New
sources From TAR Containing asphalt (thermal) From Asbestos?
Gravel Sand Filler From Asbestos? From railway ballast From
household waste incineration (IBA) Metals Fine and course
aggregates Conclusion Netherlands: Europe: Market: .
recycling aggregate is very important resource regulations complex
but helpful for recycling Europe: more and more influence on
national regulations resetting NL regulations Market: many options
for products and applications road base market stabilizes other
outlet needed: aggregates for concrete . Thank you!
