Why Capital Compost?

Through the Captial Compost initiative we help:

  • the environment by processing about 6,000 tonnes of green waste each year, including food waste from Wellington restaurants and other premises
  • schools, childhood education facilities and community garden groups to create food gardens, or complete native plant-restoration projects, through our community grants.

How do we turn green waste into compost?

Capital Compost shreds the organic waste. Through regular turning, we can get the garden waste to break down more quickly and at a more constant and higher temperature than most people achieve at home.

When 'cooked' (takes about 3 months), we screen it to get consistently-sized particles so that garden nutrients can be easily released.

We then get a sample of the compost tested to make sure it meets the Composts, Soil Conditioners and Mulches Standard. Samples are also tested for weeds and any other contaminates that aren't good for the soil. When it has the all-clear, the compost is either put up for sale or used to make other materials in our garden range.

All Capital Compost's products are sample tested to make sure they are 100% weed-free and organic.
