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.

Waste recycling

Winstone Wallboards works closely with local waste companies on initiatives to recycle plasterboard waste.

Green Gorilla has introduced a plasterboard recycling service in Auckland. Plasterboard is collected separately from general building and construction waste though the waste volumes and tonnages are recorded and reported per project for builders and their customers which allow 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 now be purchased via your preferred merchant branch and included as part of your new GIB® Deliver To Site order.

Recycling bags arrive to site along with your GIB® plasterboard order, when the bag is full simply contact Green Gorilla to arrange pick up from site (service only available in the greater Auckland area).

In Christchurch, plasterboard manufacturing waste from Winstone Wallboards in Christchurch is processed by Canterbury Landscape Supplies with off-cuts shredded and screened to return it to gypsum form. The recycled gypsum is supplied as a soil conditioner to farmers, freight companies, orchards and vineyards.

Local manufacture

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.
