Organic matter is a very valuable resource. Our planet is a ‘balanced’ ecosystem and each part relies on many other parts for its survival. Most of the life on earth is contained in the biomass or topsoil that lies on the earth’s surface.

How does composting make a difference?

Soils play a vital role in carbon sequestration and water retention - approximately 20% of global carbon is held in the soil. By composting, we are putting the biomass into soil back rather than just taking it away.

When organic waste breaks down in an anaerobic environment - like in landfill - a significantly higher proportion of methane gas is produced, than if it breaks down in an aerobic environment - like a compost pile, where mostly creates carbon dioxide. Methane is a greenhouse gas that is 23 times more damaging than carbon dioxide.

So, composting your food waste reduces the production of methane, whereas food waste in landfill can contribute greatly to the greenhouse effect and climate change.

Best of all, we can use organic waste to create a useful product that helps to grow more food!

How exactly do we do it?

When we collect your compostable waste (or more specifically, a whole truck-full) we then head south to Tuakau, where we dispose of the compostable waste at a commercial facility, Envirofert. Here, the compostable waste is mixed with about 10 times as much green waste, mulched together, and then laid out into long piles called 'air assisted windrows'...Long story short, the organic waste is blasted with hot air (around 75 degrees) which over about 9 weeks, breaks everything down! After maturing, the fresh compost is then distributed to farms in the Pukekohe and Bombay areas. Fun fact: most of the compost generated by our collections here at We Compost is currently being used on kiwifruit farms! So you can see, it really is a full circle!
