Recycled milk bottles are used in the site's drainage system - 1,108,430 have been used to date, achieving a 90% carbon saving. Recycled materials, including bricks, metals, broken concrete and timber, are being used throughout the development. All materials - nearly five million cubic metres - have been retained on site for landscaping, resulting in a carbon saving of 7,978 tonnes.
Andrew Pilsworth, Managing Director, National Logistics at SEGRO, said: "Rapid advances in construction techniques and building design are enabling developers to deliver more sustainable warehouse units, but SEGRO Logistics Park Northampton will be the first time that net zero has been achieved across an entire large industrial site, including the provision of all supporting infrastructure on and off site."
The site is powered by hybrid generators, saving 12 tonnes of carbon per week compared to 100% diesel. Vehicles are powered by green diesel (a hydrogenated treated vegetable oil), with over 250,000 litres used to date, saving 607 tonnes of carbon. Concrete used on site has an average of 35% less carbon than traditional mixes. All steel used will have at least 30% recycled content.
