Wshop191030: Evidence for processing organic waste to biogas

We would like to thank our event sponsors:

EECA Business, BPO Limited, Calibre, Hitachi Zosen INOVA, and Organics Group


Interim Climate Change Committee (ICCC) has been looking at ways to incorporate stakeholder evidence and information to support development of New Zealand’s first three emissions budgets out to 2035.  The ICCC has called for evidence on options available to reduce greenhouse gas emissions over the period 2022 to 2035.

This workshop was to share evidence from recent and proposed projects and to identify those aspects which make projects successful, and identify barriers where new policies or assistance would assist get more projects committed. The workshop covered the treatment of solid and liquid municipal organic wastes, the use of food processing residues, and the opportunities for use of agricultural organic wastes.
