Yesterday Road Science celebrated the opening of an electric bitumen tank in Lyttelton! The tank boasts five million litres of storage for the substance that shapes New Zealand’s roads and pavements. It is made from a repurposed oil tank, and took the team 18 months to convert. The decision to repurpose and refurbish an old tank was made in line with best building practice for sustainability, as a new build would increase our carbon emissions.   The tank is the first of its size in Australasia to be fully electrified, instead of being process-heated by fossil fuels. Now that the tank is operational it has been assessed by Energy NZ and the results show significant carbon emissions savings, totalling 290 tonnes per year.   Craig West, Downer EGM for Transport says; “Downer is committed to finding solutions to decarbonise, and the innovation Road Science has delivered in the construction of our first electric tank is really impressive. They continue to be industry leaders and to find opportunities for us to build a sustainable future. The emissions reduction we have made at the Lyttleton plant provides us with a successful model to work from across our business.”   Construction of the tank began in advance of a decision made by Refining New Zealand to halt the production of approximately 100 thousand tonnes of bitumen at the Marsden Point refinery in February 2021. New Zealand uses 160 thousand tonnes of bitumen per year for surfacing roads including airports, ports, pavement and other roading infrastructure, and businesses are now required to import the product from as far as Europe and the United States. “The new tank increases onshore storage space significantly for the South Island, building resilience for our business and ensuring supply certainty for the entire roading industry, I would like to acknowledge everyone involved for making this happen, it took the Road Science Team, contractors and industry experts to get this tank operating. I would also like to thank Maui Stuart from Te Hapu o Ngati Wheke for blessing the tank at the official opening yesterday," Doug Carrasco, General Manager. #downer #sustainabilityatitsbest #greatworkteam
