Whareroa produces its own electricity, using a gas-fired co-generation plant. The plant produces 380 GWh of electricity per year, and more than 60 per cent of this feeds the national grid. Waste heat is used to run the site's milk processing plants.
It was the first site to implement more efficient manufacturing practices under Fonterra's Operational Excellence Programme – known as lean manufacturing. The site has achieved cost savings through improving its eco-efficiency, energy reduction, effluent losses and health and safety performance.
Whareroa wasn't the only Taranaki site to be recognised at this year's awards.
Kapuni won two awards – the Best Consumer and Foodservice Site and the People's Cup, while Eltham was also runner-up in the Best Consumer and Foodservice.
