UK’s leading sustainable construction solutions business is working with Renault Trucks & Total Vehicle Solutions to develop the next generation of mixers, with ambitions for their eventual widespread use across its urban operations. As Tarmac procures 100% of its site electricity from clean energy sources, wind, solar and hydro power only, the new vehicle will operate as a carbon neutral solution. In addition to making the transition to zero tailpipe emissions, EV mixers reduce noise and vibration, while contributing to improving air quality, particularly when operating in urban areas and low and zero emissions zones.

By utilising telematics information available for its fleet activity, the design team has been able to match the normal delivery profile of a truck to the indicative range of 120km and the power draw from the mixer drum in transit and discharge. The truck will have the ability to fast charge within 1.5–2 hours if needed and has a 265kWh battery with a guarantee of up to 10 years operation.

The 26 tonne Renault Trucks E-Tech D Wide will come with enhanced safety features, as the batteries provide a lower centre of gravity, improving stability. The speed of the drum rotation is also computer-controlled to optimise energy consumption for loading, unloading and transit of different types of mix.

The design of the vehicle has been developed following successful collaboration last year through Tarmac’s Supplier Innovation challenge and Supplier Sustainability Week, which saw suppliers working to find solutions to accelerate the industry’s progress to reach net zero.

Tarmac operates one of the largest HGV fleets in the UK, and this order comes as part of the company’s wider strategy to decarbonise its vehicle network, following its commitment to upgrade its 2,000-strong fleet of corporate cars and vans to EVs by 2030.
