Recycling of waste into a secondary product seems to cause problems in the the life cycle assessment. This presentation is trying to visualise the flows, boundaries and principles of calculation as defined on the CEN-standard text in EN15804 and EN15978 (assessment for environmental performance assessment of respectively construction products and buildings)

Transcript

  • 1. Recycling: bridging to another life cycle Ir. Chris Hamans The Netherlands
  • 2. CPR : European regulation 305/2011 2
  • 3. BRCW 7 : SUSTAINABLE USE OF NATURAL RESOURCES The construction works must be designed, built and demolished in such a way that the use of natural resources is sustainable and ensure the following: • (a) recyclability of the construction works, their materials and parts after demolition; • (b) durability of the construction works; • (c) use of environmentally compatible raw and secondary materials in the construction works. 3
  • 4. Sustainability sustainability ENV SOC ECON Technical design Functional design • Without meeting the functional needs there is no sustainability • Without meeting the technical needs there is no sustainability 4
  • 5. recyclability • BRCW#7a: recyclability of the construction works, their materials and parts after demolition; • Recycling of functions? • Recycling of technical performance? • Bringing back into the same or another product life cycle • Recycling is bridging 2 or more product life cycles 5
  • 6. Product 1 6
