With construction and demolition estimated to produce up to 50% of all waste generated in Aotearoa New Zealand, the GreenStuf Takeback Programme seeks to close the recycling loop for insulation and divert waste from landfills.
Working with Naylor Love, we chose Manurewa High School’s new Business Hub as a pilot project for the Takeback Programme. A new build of nine classrooms, a library, amenities and technology spaces, the low-maintenance, low-energy design encompasses a warm roof, automated skylights, double-glazed joinery and recyclable GreenStuf insulation.
‘Naylor Love were briefed by the school to minimise waste on site during the construction phase,’ says Aidan Hill, GreenStuf’s Technical and Sustainability Manager. ‘With GreenStuf already in the specification, we used this project as a trial to investigate how the scheme could be rolled out and what sort of challenges we might face on site.’
GreenStuf makes a great trial product
GreenStuf is a thermal and acoustic insulation made from 100% polyester fibre. Made on a zero-waste manufacturing line with a minimum of 50% recycled content, it was the ideal product to trial the Takeback Programme, as both packaging and product are recyclable at the end of their life. And by recycling the leftover material, offcuts can go into creating the next generation of products.
‘We put in a collection bin on site, where contractors would contain the packaging and insulation offcuts,’ says Aidan, ‘which we would then collect and recycle. It was essential that we had the right installers on site to ensure the products were separated properly and not contaminated with other material.’
