How does the Organics Processing Plant work in Christchurch?
I'm glad you asked, this link http://www.ccc.govt.nz/homeliving/rubbish/kerbsidecollection/organics/index.aspx will explain it all, or check out this fancy pants video. http://www.youtube.com/watch?v=6nc8ufeO984
How much organic waste is collected and brought to the OPP and converted to compost each year?
Around 50,000 tonnes of foodscraps and greenwaste is collected from Christchurch homes which is converted into 50,000 cubic metres of compost.
How does Living Earth deal with the inorganic rubbish that may appear in your green organic bins?
Items such as glass, tin and plastic are removed starting at the beginning with a visual 'picking' on arrival and ending when the compost is passed through a fine screen before being sold.
What must not be placed in your green organics bin?
Do not place plastic wrapped around food, ash from the fireplace timber products and sawdust in your organics bin.
How long does the compost take to make?
The foodscraps and greenwaste collected from your gate is composted in an in-door tunnel system for up to 7-10 days, and subsequently aged in windrows outside for up to 30 days. Greenwaste dropped off at Metro Place is composted outside in windrows for around 90 days.
Where does the compost go from the OPP?
Currently all compost is sold to the Canterbury farming community. Canterbury soils suffer from years of intensive chemical fertilizer application and compost helps re-build healthy soil structure and increases moisture retention in the soil.
Can I buy compost in Christchurch?
Living Earth sells the compost to the local farming community, so there are no supplies available to Christchurch residents. But watch this space...
I've heard that the compost may contain herbicide residues - is this true?
Unfortunately it is sometimes the case with the Christchurch OPP compost. Residents should not place grass clippings in their green organics bin or drop them off for recycling, if they have previously sprayed their lawns with a selective weed-killer containing the active ingredient Clopyralid.
How does Clopyralid affect plant growth?
It can cause distortion of new growth in vegetables such as tomatoes, potatoes and beans
How do I make sure my green waste and food waste is recycled at the Living Earth Organics Processing Plant in Christchurch?
By placing all your organic waste - kitchen food scraps and garden cuttings and weeds - into your Christchurch City Council Organics green bin and placing it at your gate on your collection date.
