Waste Recycling liyana mohamed yusof

municipal solid waste ‘ food, packaging, garden organics, plastics, glass, steel cans, paper/cardboard’

commercial & industrial waste ‘ food/kitchen wastes, cardboard, paper, metal, wood/timber, tyres/rubber, plastics’

construction & demolition waste ‘ soil , rocks, rubble, asphalt, timber, metals, concrete, plastics, plasterboard, asbestos ‘

‘ 681 kg of waste per household per year is collected from kerbside in metropolitan and 722 kg in non-metropolitan’

factors
The growth of population
Wealth
The growth of technology & economy
The growth of packaging industry and industrial
products
Lack of public awareness

landfills
The important part of South Australia’s waste management
infrastructure are landfills because the waste disposal here
has been dominated by these landfills.
Adelaide is served by :
Southern Waste Depot , Maslin Beach
Southern Region Disposal Depot , Mclaren Vale
Integrated Waste Services Balefil, Dublin
Waste management New Zealand, Inkerman
Waste management New Zealand, Nuriootpa
Northern Adelaide Waste Management Authority Balefil, Uleybury
These infrastructures provided 60 millions cubic
metres of landfill airspace

Major landfills service in Adelaide and small rural landfills
received 12.8 million tonnes of solid waste every year.
This is happening because due to low landfill costs, it is
more effective to dump rather than recycle.
When the waste is disposed to landfill, we will bury many
useful resources and prevent ongoing use of the materials.

It needs a high level of design to ensure the sitting,
rehabilitation and management of the landfills.
The operators of the landfills has to encourage the local
government and businesses to enter the long-term
contracts and set a minimum volume of waste to them.
This again will encourage them to dispose the waste to
the landfill instead of recycling.

Global warming
In landfills, the anaerobic (without oxygen) decomposition
of the organic leads to emissions especially methane
and also carbon dioxide and nitrous dioxide.
Methane is more effective green house gas than carbon
dioxide and has much greater greenhouse effect.
However the amount of the methane depends on the
quantity of the waste and the design n management
of the landfill site.

future issues
Shortage of landfill
In 2004 the disposal from the six landfills licensed to
received Adelaide's waste will only meet the Adelaide’s
requirement for several decades.
The will be possibilities that Adelaide will has not enough
space for landfill sooner than that.
They will need a new landfill and this can create more
issues in finding the logistic.

Amount of waste disposed of to landfill increased from 860,000 tonnes in 1995-1996 to 1,1100 tonnes in 2001-2002

32,800 tonnes from domestic waste
169,000 tonnes from commercial & industrial waste
509,000 tonnes from construction and demolition waste

recycling
SA is one of the most best in recycling. It managed to divert
65% recyclable from the landfill
The waste is either recycle within the plant or will be
transferred to business that could process the material.
One of the major challenge for recycling is they have to
to compete with landfills.
Other problem is low value waste and mixed of waste
make it difficult to recover usable materials.
This waste will then be disposed in the cheapest way
which is landfill.

“ Despite increase in the number of people recycling, the amount of waste going to landfill is increasing’ The 2003 State of the Environment Report for South Australia
