GIB® Plasterboard - a green building material
GIB® plasterboard is a sustainable, non-toxic, compostable product made from natural gypsum and 100% recycled paper.
GIB® plasterboards do not use fly ash, a derivative of coal extraction, as a bulk filler* in place of naturally occurring gypsum.
* 10mm GIB Aqualine® board uses less than 0.7% fly ash as a processing agent, not as a bulk filler.
Green Gorilla Operates a plasterboard recycling service throughout the greater Auckland area. Plasterboard offcuts are collected from site with volumes recorded and reported per project allowing plasterboard recovery statistics to be provided as part of total site landfill diversion and environmental reporting for Greenstar and Homestar accreditation.
2m³ Green Gorilla plasterboard offcut site recycling bags can be purchased via your preferred merchant branch and included as part of your GIB® Deliver To Site order or alternatively a wider range of bag options can be ordered directly from Green Gorilla. greengorilla.co.nz.
Waste Management operates a plasterboard offcut collection service in the Christchurch area. Offcuts are then processed locally by Canterbury Landscape Supplies where the gypsum core is extracted and used in a range of compost and agriculture products. wastemanagement.co.nz
Allwaste and Waste Management operate plasterboard offcut collection services in the Queenstown area. Plasterboard offcuts are then transported to Canterbury Landscape Supplies for recycling. allwaste.co.nz, wastemanagement.co.nz
Winstone Wallboards is currently working with local waste diversion providers to expand plasterboard waste recycling options.
GIB® plasterboard and compounds are manufactured in New Zealand*. We have complete oversight of our factory conditions and the teams who work in our manufacturing plants. Our decision to manufacture locally supports local jobs and directly supports the country’s economy.
*Note: GIB Barrierline® plasterboard is manufactured to Winstone Wallboards’ specific specification from a reputable overseas manufacturer.
