3. Introduction
• New Zealend is an island country in the southwestern Pacific Ocean.
• New Zealand is long and narrow (over 1,600 kilometres (990 mi) along its north-
north-east axis with a maximum width of 400 kilometres (250 mi)), with about
15,000 km (9,300 mi) of coastline and a total land area of 268,000 square kilometres
(103,500 sq mi)
• the population of New Zealand was estimated at 4.69 million and was increasing at a
rate of about 2.1% per year.
• New Zealand industries and households discard over 3 million tonnes of construction
and demolition debris to landfills and cleanfills (about one tonne per person).
• more than 1 million tonnes of plant matter and food scraps are sent to landfills (320
kilograms/per person), 600,000 tonnes of paper and cardboard (about 170 kg/person)
& 220,000 tonnes of plastic (about 60 kg/person).

6. APPROACHES ADOPTED IN NEW
ZEALAND
• Converting existing small landfills into transfer stations.
• Used containers as a retaining wall, hooker bins for transferring waste.
• Custom designed transfer systems.
• Simple skip bin based transfer station.
• Grab based loading systems (transfer pit into truck).
• Simple wool fadge based recyclables collection.
• Store recyclable material in shipping container.
• Shredding/crushing green waste.
• Limiting opening hours.
• Rubbish skip made available a specific, limited time e.G. Saturday
morning at local hall.

8. WHEELIE BINS
• Bins available in sizes 80L, 140L and 240L bins, with weekly,
fortnightly and monthly pick up options for different areas.
• Taking care of a garden is hard work. Fortunately, clearing
away your lawn clippings and other garden waste isn’t. With
bin sizes from 80L to 240L to match your gardening activities,
you can make room for that new flower bed tomorrow.

9. SKIP BIN
• Skip Bin sizes range from 2m3 mini skips to
15m3 Jumbo Bins. For heavy materials like bricks,
broken concrete and sand, our 3m3 cleanfill bins are the
best choice.

10. FLEXIBIN
Keep garden waste in a green
flexibin until it’s full means
you don’t have to transport it.
Water drains away, so there are
no soggy leaf piles to deal
with. And they are strong
enough to capably handle the
usual garden waste as well as
heavier materials like soil and
tree branches up to 20cm in
diameter. And where possible,
your suitable garden waste will
get a second life as valuable
compost.

11. TRANSFORM STATIONS
• Asbestos
• Dangerous goods such as;
flammable liquids, flammable
solids, poisons, pool chemicals
and gas bottles
• Agricultural residues or
chemicals
11
•Scrap motor cars
•Animal by-products
•Medical waste of any nature
•Firearms
•Radioactive materials
•Explosives and fireworks

12. For Businesses

13. ELECTRIC RUBBISH TRUCK
• They collect waste form 1200 home in a day which preduce 6000kwh electricity
which is able to run a truck for full day and fill the electricity demand of 275 home.
• Using 23 trucks at present.
• At the end of 2017, target to add 1000 more electric trucks.

14. REDUCE
14
•Consider alternative products with less packaging
•Consider alternative products with easily reusable or recyclable packaging
•Consider bulk purchasing
•Reusable products
RE-USE
•Allow transfer station operators/supervisors to sell reusable items (furniture,
clothing etc.)
•Location at transfer station/disposal site for reusable items
•Promote informal networks for exchange of reusable materials (cardboard
boxes, plastic containers)

15. Type Solution
Compostable
material
Promote home composting or school based worm farms
Putrescible
waste
Potential for food waste to be fed to pigs (under proposed
biosecurity regulations will require cooking at 100°C for 1
hour)
Paper/cardboar
d
Reuse of boxes where appropriate recycling of
uncontaminated paper/cardboard (need simple collection and
transport systems) potential for composting of contaminated
cardboard and pape
Plastics Reuse of containers and bags where appropriate recycling
Metal Stockpile for mobile crusher/recycling
Glass Ground up for abrasive blasting media.
15
RECYCLE / COMPOST

16. DISPOSAL OF RESIDUAL WASTE
16
Type Solution
Cleanfill material Disposal to local cleanfill landfill
Disposal to local, high standard landfill
Transport to high standard landfill
General waste Disposal to local, high standard landfill transport to
high standard landfill
Hazardous waste Dedicated drop-off point at transfer station/disposal
facility periodic hazardous waste collections
Final disposal of waste can be managed within the local area or removed, depending on
location, volumes and local facilities available.
