Müller Milk & Ingredients is trialling different technologies to reduce the carbon footprint of its HGV fleet.
The dairy company, which maintains industry leading service levels by operating logistics in-house, is testing whether solar panels and kinetic energy can power its refrigerated HGV trailers, as an alternative to refrigeration powered by diesel engines.
Müller, in partnership with Sunswap, trialed the delivery of fresh milk using refrigerated trailers that are battery and solar-powered. 100% of the energy required came from free clean energy collected by the solar panels.
In collaboration with Carrier Transicold, the business is also testing a refrigerated trailer system powered by kinetic energy. The Carrier Transicold Vector eCool converts energy generated by the trailer axle and brakes into electricity, which is then stored in a battery pack to power the refrigeration unit.
As Müller continues to prioritise supply chain resilience and lowering carbon, the trials aim to establish whether renewable energy solutions with a lower carbon footprint allow the business to maintain its quality and service levels, which sit above 99% in 2023.
Per trailer, the solar and battery-powered Sunswap system would eliminate all diesel, saving 3,700 litres and 9 tonnes of carbon every year. Carrier’s Vector eCool system would eliminate all carbon emissions associated with traditional refrigeration units operating with an auxiliary engine.
Following completion of the trials, the business will consider further testing or a wider rollout throughout its network.
