This is the third in a series of webinars about organic and food waste, and how these are managed within the waste hierarchy. The purpose of the webinar series is to provide real world application of the waste hierarchy in action. Each session will focus on increasing the understanding of what that level means in reality when dealing with organic and food waste, how actions taken at each level contribute and why they are important.

The waste hierarchy is a framework prioritising strategies from most preferred (prevention) to least preferred (disposal) options for waste management. Efforts made at the top of the hierarchy avoid the extraction of valuable resources, keep valuable resources in use and prevent valuable resources from going to landfill.

Our third webinar will focuses on organic and food waste initiatives at Level 3 - Recycle, Compost, Anaerobic Digestion which in the context of food surplus or waste means recovering materials from waste to be reused or recycled. "Recycling" typically involves processing materials to make new, usable products, while "composting" is a natural process where organic waste (like food or garden waste) decomposes, returning nutrients to the soil. "Anaerobic digestion" is a process which breaks down organic matter in the absence of oxygen producing biogas (a renewable evergy source) and nutrient-rich digestate which can be used as a fertiliser. 

Join us in this session to hear from different experts on how actions to Recycle, Compost and Anaerobic Digestion make a difference in tackling food and organic waste in New Zealand.
