Precycling is a term I adopted within FutuREstorative to describe the decision making process when specifying, procuring, ordering and calling off materials. It is the thought process, not for only the avoidance of waste but in considering net-positive and secondary uses for a product at the end of its initial use.
Precycling is defined as ‘making purchasing decisions that will ultimately eliminate, delay, reduce the need to recycle or dispose of waste” and should be at the top of all waste hierarchies, as indeed it now is with some of the organisation whom I am supporting.
I have suggested elsewhere that product or material data sheets or passports within BIM should contain deconstruction, disassembly future use options within their attributes, hence enabling and informing precycling decisions.
“Precycling is one of the gateways into a construction circular economy” and assists in making the conversion from Site Waste Management Plans (that detail methods for reducing and better management of waste) to Material Conservation Plans (that detail methods for conserving resources)
Material Conservation Plans are a Living Building Challenge requirement under the Materials imperative. A framework for UK Project Material Conservation Plans is included within FutuREstorative
In January 2017 BRE published Material resource efficiency in construction: Supporting a circular economy (FB 85) which although still having a focus on Site Waste Management Plans assists in shifting waste thinking further up stream, noting that Material resource efficiency can be applied across a construction project’s life cycle, but with the greatest benefits at early, pre-construction stages
“There is increasing awareness that improved material resource efficiency will produce benefits across the construction industry such as cost savings, reduced environmental impact and an enhanced reputation. At a construction project level, resource efficiency can be implemented at all stages (design, procurement, construction, in use and end of life) using established tools and techniques.
This guide describes the material resource efficiency requirements in BREEAM. It provides the background, drivers, benefits and practical advice to assist clients, designers and contractors in achieving higher levels of material resource efficiency. It will also be useful to product manufacturers, suppliers and waste management companies”
