Technical Innovations

Using the latest science and technology to make the most of the business opportunity that food waste provides.


Two-thirds of the world’s 50 largest food companies are now committed to cutting food waste in half. The New Zealand government has recognised the business opportunity that food waste provides and has announced a significant investment in converting unmarketable crops into value-added products for export through the Bioresource Processing Alliance (BPA), a Ministry for Business, Innovation and Employment (MBIE) funded collaborative research programme.

Phil Bremer

Lead Researcher for Technical Innovations

Our researchers have added expertise in:

  • Extraction, optimisation and evaluation of bioactive compounds from food waste

  • Utilisation of food waste for energy, food packaging and related issues

  • Edible food coatings

  • New product opportunities relating to waste

  • Accurately predicting and enhancing the safety, quality and shelf-life of food and beverages

  • Determining the factors (chemical, enzymatic, biological) responsible for the end of shelf-life


Our Upcycled Food Lab

The Upcycled Food Lab utilises the Theme’s food science expertise and resources to work with businesses to create upcycled products from waste and by-products. We provide various services, from research and consultancy to food product development.
