VINCI companies collaborate to drive down embodied carbon at EcoPark South

EcoPark South is the 100M recycling infrastructure contract awarded to Taylor Woodrow as part of North London Waste Authoritys (NLWA) 1.2bn programme to create a new waste management hub and Energy Recovery Facility on the site of the existing Edmonton EcoPark.

The team is collaborating with VINCI sister companies Bachy Soletanche, Roger Bullivant and Vibro Menard to deliver the projects geotechnical and piling work, with a strong focus on innovation to minimise the embodied carbon footprint.

The groundworks for the project have started and the team are deploying CFA piling, controlled modulus columns (CMCs) and a low permeability Trenchmix cut off wall to construct the foundations for the Resource Recovery Facility and the Reuse and Recycling Centre.

The use of CMCs brings considerable environmental benefits, which include; the elimination of reinforcement cages normally required in CFA piling, a reduction in the thickness of the ground slab saving on concrete and steel, and a reduction in the arisings produced due to CMCs being a displacement solution.

Trenchmix further enhances the projects environmental credentials through offering approximately a 30% reduction in the embodied carbon, when compared to the alternative of a traditional sheet piled wall this saving has contributed to an overall reduction across the project of between 10-16%.

It is the first of several sustainable methods being used to both construct the project and to deliver features that will enhance its sustainable credentials once complete. These include a rainwater harvesting system and a clean energy system powered by photovoltaic panels and use of ground and river sources for heating/ cooling in the buildings.

The project is part of North London Waste Authoritys drive to tackle the climate emergency by diverting up to 700,000 tonnes of non-recyclable waste from landfill. The project's carbon savings are the equivalent of 215,000 tonnes of CO2 each year, in an area that is home to around 2 million people.
