Abstract – Tuhinga Whakarāpopoto

This report adds to current understanding of the scale, scope and nature of organics collectors and processors across Aotearoa, with a focus on composters. The report is primarily designed to support those at central and local government charged with making investment and procurement decisions in relation to the infrastructure and services for collecting and processing organic materials. We conducted a national survey of operators, with the results showing a lot of diversity in the sector. To develop a shared language to support decision-making on organics materials management, the report draws on international literature and the survey results to develop a simple taxonomy for distinguishing operators based on factors most relevant to procurability and scaleability. This taxonomy is then used to explore the various challenges, impacts and outcomes for each type of operator.
