MIMICO Environment & Community Award

Wayne Scott, MIMICO Award judge, said Road Metals stood out in a very strong field of entries due to the originality of this project in providing power to quarry fixed plant, while delivering significant reductions in CO2 emission. The solar system complemented work already done at the site to replace diesel powered trucks with an overland conveyor.

In collaboration with Platinum Energy, pioneering 528kWp solar PV system on rehabilitated quarry land. This project not only revitalised the site but also maximised land use efficiency while minimising environmental impact. Annually offsetting nearly 150 tonnes of CO2 equivalent emissions, which is over 55,000 litres of diesel, this initiative underscores commitment to sustainability and operational efficiency at Rolleston Quarry.

Wayne Scott, MIMICO Award judge, said Fulton Hogan won through due to the scale of this ecological project to establish fish passage between water course adjoining Willowbank Quarry.

Inheriting a partly constructed but non-operational fish ramp from the previous operators of the site, Fulton Hogan redesigned and constructed the fish ramp that drops down 25m over 90m to enable fish passage from a stream below the quarry to the upper catchment areas on the Willowbank farm.

Wayne Scott, MIMICO Award judge, said Winstone Aggregates won through doing the first Environmental Product Declaration (EPD) for aggregate and sand products in New Zealand.

In February 2022 Winstone Aggregates released their first EPD for aggregate and sand products, which covers the embodied carbon of products from eight quarries across the North Island. To be a sustainable business means to operate in a way that is protective of people, our community, the environment, and the economy. The EPD does this by focusing on five key workstreams; social, biodiversity, water, waste and carbon reduction.

Bernie Napp, MIMICO Award judge, said Blackhead Quarries won through being the first quarry in the country to use an electric truck. The 30 tonne truck, imported from China, costs about $4 a day to run, carting 600 tonnes of aggregate at the Logan Point Quarry in Dunedin, as opposed to burning 80-90 litres of diesel.
