Our commitment to sustainability
Green Vision is committed to providing environmentally sustainable engineering solutions that enable the recovery and reuse of materials and assets through the creation of new products and lifecycles.
Green Vision was established out of a desire within the industry to take greater responsibility for the impact waste materials from construction and maintenance activities have on the environment. The founders of the company wanted to reduce the pressure construction places on the country's natural resources and in turn, reduce construction waste to landfills.
In recent times, there has been increased attention on the industry to identify and take action on waste and resource use by adopting a more sustainable approach to the recovery of construction and maintenance of assets that reach the end of their useful life.
The biggest challenge has been to turn ideas, policies, and plans into engineering reality. Green Vision is at the forefront of this change encouraging the adoption of low-energy manufacturing techniques and the recovery and recycling of construction wastes. Green Visions’ robust production disciplines ensure their clients receive high-quality products.
Green Vision is working on developing tools to help companies measure their carbon footprint for respective projects when using recycled products.
Environmental Product Declaration (EPD)
The ability to measure carbon savings can be achieved by using tools such as an Environmental Product Declaration (EPD) for Recycled Crushed Concrete (RCC) and Recycled that will help you determine the reduction of carbon footprint achieved when using recycled products versus virgin aggregates.
Green Vision has launch the RCC EPD in August 2022 which is now available for download and to support your sustainability goals.

Green Vision looks forward to working with you to recover materials and repurpose them to meet your needs. Together we can better combat climate change and support our environment.
Carbon reduction by using recycled products example
This calculation has been compiled specifically for Auckland Council
Auckland’s infrastructure will help to better protect and manage our finite natural resources while improving the whole of life cost to our city. Green Vision is committed to providing sustainable, high quality recycling components for use in infrastructure and construction.
Benefits of recycled crushed concrete compared to natural aggregates include:
+ Reduced tipping and freight costs.
+ Cost Effective
+ Achieve reduce greenhouse gas emissions.
+ Reduce pressure on landfill resources
+ Reduce pressure on natural resources
An example:
Comparison of the aggregate required for the construction of 1 kilometre of road pavement, with two lanes in either direction. (Similar to main road access around the Auckland CBD and inner city suburbs)
Based on current market rates, the use of recycled crushed concrete would save 18% or $55,000 per kilometre versus using natural aggregate sourced from within the Auckland region. In addition, the use of recycled materials would remove approximately 13,428 tonnes of concrete from clean or managed fill.
Using the ISCA rating method the carbon reduction in CO2 is also significant. The use of Green Vision recycled crushed concrete would equate to a carbon reduction of 104.5 tonne of CO2 emissions, the equivalent of a 55% reduction compared to aggregates from one of Auckland’s major quarries.
A commitment to a consistent pipeline
The design modelling prepared by Downer’s Transport Services technical team assumes 100% use of either recycled crushed aggregate or natural aggregate, not a combination of products.
While use of recycled aggregates is increasing across the region, the volume required for 1 kilometre of road construction alone would use a significant proportion of available supply.
As a result, any change in design and procurement practices by asset owners to specify recycled aggregates would need to include detailed consultation with the sector to ensure a viable sustainable supply chain for market.
