PepsiCo is launching a pilot project to convert over 40,000 litres of used oil into hydrotreated vegetable oil (HVO) at its snack plant in Burgos, Spain. HVO is a 100% vegetable-based biofuel – the HVO generated will be used to power the company's fleet of lorries that transport PepsiCo products, and is estimated to save 380 metric tonnes of CO2 per year. Biofuel is said to be able to reduce CO2 emissions by up to 90%, however, its availability is limited. As a result, PepsiCo – whose primary, secondary and fleet transport accounts for 11% of its emissions in Spain, Italy and Portugal – is promoting this type of initiative and extending its use in order to eliminate the use of diesel in the medium term. The company has also launched a pilot test in collaboration with Spanish supermarket chain Dia for transport with ‘duotrailer' trucks in the country. The truck features two trailers attached together "like a train carriage" and enables transportation of up to 6 tonnes of snacks. Javier Pérez Martínez, head of sustainable transport for PepsiCo Europe, said: "These are pilot tests that we hope will bring us very positive results and can be implemented definitively”. The projects are part of ‘PepsiCo Positive’, a “strategic business transformation with sustainability at its core”. Martínez added: "We want to and must be part of the solution and with initiatives like these, we are doing our bit to reduce greenhouse gases and advancing our sustainability strategy at the heart of PepsiCo Positive".
