description
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)

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.

• Without meeting the functional needs there is no sustainability• Without meeting the technical needs there is no sustainability

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
