Road Science has worked closely with many sustainability networks including the Sustainability Business Network and the Energy Efficiency Conservation Authority to develop continuous improvement programs. These include gains in both energy efficiency, waste minimization and waste material recycling.

Road Science has been working on energy conservation and decarbonisation for over 10 years. This started back in 2008 when Road Science first established a working relationship with the Energy Efficiency Conservation Authority (EECA).

One of our latest success stories which encompasses our passion for sustainable practices was the construction of a new bulk bitumen tank in Lyttelton that provides low carbon emissions. When looking at new bulk storage options a collective assessment was completed by the Road Science Engineering Team and our energy consultant Energy NZ. Our goal was to look for feasible low carbon process heat options. From this work Road Science constructed a bulk bitumen tank with direct electric heating only, this provides a carbon saving from traditional hot oil diesel furnace of 209t.CO2/year.
