DBPAS 10: Characterisation of food waste derived biofertiliser

A literature review of the characterisation of biofertiliser, including aspects related to:

  • Food waste feedstock - a detailed description of the organic materials used
  • Agricultural benefits - A summary of peer-reviewed research comparing biofertiliser to conventional fertilisers
  • Accreditation and risk management - An overview of New Zealand accreditation schemes and strategies for managing contaminants 
  • Application and storage - Practical considerations for handling and storing biofertilser
  • Social considerations - An exploration of public perception and societal factors influencing biofertiliser use in New Zealand

Digestate forms - Analysis of liquid, sludge and dry digestate.

This review draws from both local and international scientific research, certification schemes, and technical publications.  It serves as a foundation for BANZ to develop clear, high-quality information for biofertiliser users and producers.  Additionally, it identifies areas requiring further study to support the development of an accreditation scheme tailored to Aotearoa New Zealand's unique needs.
