The Better Buildings Partnership has released a draft of its Strip Out Waste Guidelines for comment. The guidelines aim to assist tenants, building owners, property managers and demolition contractors to reduce the amount of waste sent to landfill from defit projects by setting out a general methodology for best practice.
The guidelines have specified the various elements that apply to each of the stakeholders in a defit – with a clear allocation of responsibilities and opportunities to contribute to better outcomes.
They were developed based on the BBP’s expertise and the work done by its Waste Technical Working Group, chaired by Lendlease senior sustainability manager investment management Jon Collinge.
There was also input from BBP partners and suppliers. Property managers including DEXUS and GPT; contractors including Demolition Plus, Built and Buildcorp; and Good360, a repurposing social enterprise, also contributed.
Learnings from recent case studies conducted in Sydney have been incorporated, including the Governor Macquarie Tower defit carried out by Edge Environment with funding from the NSW EPA’s Circulate, Industrial Ecology grants program.
These pilot projects informed the development of a number of tools and strategies including setting a 60-80 per cent diversion rate, making an inventory of items and materials that is coded by recovery pathway, procurement of defit contractors, compliance checks and reporting, and specifying re-used items in refits.
It also highlights the importance of agreeing on the conditions of the make good settlement early.
The BBP states that projects carried out to date have shown that a resource recovery rate of 60-80 per cent is both “highly desirable and achievable”.
BBP members have committed to implementing these guidelines and recovery targets, and are including the principles of these guidelines in their tender processes. Strip out waste industry stakeholders are encouraged to acquaint themselves with this guideline.
