Sustainability and the environment
Winstone Wallboards is committed to protecting the environment. Environmental matters are integrated into all business activities:
- Our operations strive to exceed all environmental regulatory requirements at all times.
- Protection of the environment is a day-to-day responsibility that we must all accept.
- We allocate appropriate management time and resources to address relevant environment issues and continuously improve our activities in that area.
- We will achieve our standards of performance through positive action, employee involvement and constant communication with our neighbours, local authorities and customers.
An EPD is like a nutrition label
Winstone Wallboards is proud to publish the first Environmental Product Declaration (EPD) for plasterboard in Australasia, complementing our existing Global GreenTag and Declare certifications. An EPD is like a nutrition label, but instead of calories, it covers carbon footprint, embodied energy and other environmental data. This allows the developer to choose the right product for their build, recognising that what is ‘green’ in one context may not be green in another.
“A key difference to other certifications is that EPDs quantify the environmental performance of GIB® plasterboard”, says Barbara Nebel, Managing Director of thinkstep in Australasia. Thinkstep supported GIB® plasterboard in developing our EPD and have completed over 700 EPDs globally.
EPDs are important for green building – particularly in the commercial sector – as they contribute points under Green Star, LEED, BREEAM and other rating tools. The global green building market is doubling every three years and now makes up roughly one-third of all new commercial, public and high-density residential buildings in Australia, the USA and Europe1. Locally, the New Zealand Green Building Council (NZGBC) has more than 20,000 homes registered or confirmed for Homestar, as well as 30-50 commercial buildings on its books for Green Star at any one time2.
How does it work? Under the Environmental Product Declarations Innovation Challenge3 within Green Star, a project is eligible for:
— 1 point where 2 different products hold current EPDs, or
— 2 points where 6 or more different products hold current EPDs.
The EPD for GIB® plasterboard meets NZGBC’s criteria to qualify as a product specific EPD and is therefore eligible for the full points. EPDs can also be submitted as an innovation challenge within Homestar, though the developer needs to have this accepted by NZGBC first.
When you’re next submitting a tender for a commercial or public building, think about submitting the GIB® plasterboard EPD along with it.Literature source: 1 Dodge Data and Analytics (2016).

Plasterboard Recycling Services
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 through Green Gorilla’s custom designed and built plasterboard processing system. The waste volumes and tonnages are recorded and reported per project for builders and their customers. This allows plasterboard recovery statistics to be provided as part of total site landfill diversion and environmental reporting for Greenstar and Homestar accreditation. To inquire about plasterboard recycling bags, contact Green Gorilla or visit greengorilla.co.nz
In Christchurch, Canterbury Landscape Supplies receives plasterboard waste from Winstone Wallboards in Christchurch via Container Waste Christchurch. The company processes these off-cuts by shredding and screening to return it to gypsum form. The recycled gypsum is supplied as a soil conditioner to farmers, freight companies, orchards and vineyards.

A widely recognised approach to sustainable construction is the Green Star rating scheme, a voluntary system created by New Zealand Green Building Council (NZGBC) to evaluate the environmental design and construction of buildings. Green Star is a comprehensive, national, voluntary environmental rating scheme that evaluates the environmental attributes and performance of New Zealand's buildings using a suite of rating tool kits developed to be applicable to each building type and function.
There are three credits within the Green Star Rating tool(s) where GIB® plasterboard, related products and services may contribute to Green Star points. The maximum contribution depends on the project type.
Global GreenTag Certification
Global GreenTag is one of the world's most robust, trusted and widely recognised ecolabels. Numerous GIB® plasterboards have achieved GreenTag certification. View certificates below.
Considered the most advanced sustainability certification in the built environment, Declare is like a nutritional label for building products, offering specifiers, contractors and building users insight into the ingredients used in the manufacture of building products.
Which GIB® products have Declare certification?
The following products have all achieved Red List Free status (the highest Declare status possible), meaning that these products meet the strict Declare materials standards:
- GIB Aqualine®
- GIB Fyreline®
- GIB® Standard
- GIB Toughline®
- GIB Braceline® GIB Noiseline®
GIB® plasterboard is 100% recyclable as well as having Declare status and can positively contribute to Green Star certification.
