Some days trying to get her product to market seemed like one long, uphill battle with one step forward and two steps backwards - so being named a finalist for the KiwiNet Research Commercialisation Awards was just the boost Rotorua's Sarah Heine needed.
Biopolymer Network and Barnes Plastics were today named finalists in the research and business partnership category for their work developing ZealaFoam - a sustainable alternative to polystyrene.
Ms Heine, who is the chief executive of Rotorua-based Biopolymer Network, said being a finalist was really encouraging.
"When you're trying to get a product to market, it's an endorsement that you're on the right track."
Ms Heine had been working on creating the low density moulded bioplastic foam for almost a decade and said at times, it could feel incredibly difficult.
