Each year, Auckland households send 90,000 tonnes of compostable waste to landfills. Ten percent of that is from the garden, while 40% is kitchen waste. The Compost Collective is working to reduce those figures, running free workshops on the basics of composting across the city. Jennifer Kerr works as an educator for the Collective. She joined us to explain the basics of the three main methods of composting, and to give us her top composting tips.
