WasteWhat is waste?

Waste - classifications• Household waste is that which arises from houses, flats, labour camps, schools, • universities and prisons.• Commercial waste comes from premises used for trade, business, and entertainment • such as malls, shops and recreation areas.• Industrial waste is that which arise from a factory or industrial process.• Agricultural wastes comes from premises used for agriculture such as fruit and vegetable • growing, seed growing, dairy farming, camel farming and other livestock breeding.• Medical waste comes from hospitals, clinics, nursing homes, dentists, surgeries etc. Wastes • constituted wholly or partially of human or animal tissues, blood or other body fluids or • excretions or drugs or other pharmaceutical products or bandages, needles, syringes, sharp • medical objects or any other contagious, chemical or radioactive wastes produced by • medical or nursing activities, treatment or health care, dentistry or veterinary and • pharmaceutical practices or manufacturing, research, teaching, sample taking or storage.• Marine waste comes from boats and ships visiting or working.• Packaging waste comes from products made to be used for containment, protection, • handling, delivery and presentation of goods from the producer to the consumer.• Hazardous wastes comprise of residues or ash of different activities and operations • containing properties of hazardous substances.

Household waste

Organic waste

• Organic waste produces methane in landfill. This methane is a serious greenhouse gas.

• Nutrients van leach through the soil and contaminate groundwater.

• This organic material contains many nutrients that can be used for compost/fertilizer on gardens and farms.

• Also, energy can created from this waste.

Solution to organic waste in Australia

The organic waste produced by the hospitality classes a college in Sydney is disposed of using the Pulpmaster Pro. This converts organic waste into bio fuel.

Each year, use of the Pulpmaster Pro at this small college producespower that:• prevents 476 tonnes of CO2 from entering the atmosphere • is equivalent to running 109 cars or 700 houses.• prevents the disposal of over 25,000 plastic bags.

Used motor oil contains heavy metals and other toxic substances, and is considered hazardous waste.

One quart (1/4 gallon) of oil can kill fish in thousands of gallons of water.

Used motor oil can be recycled.

Steel & aluminium

Waste tyres

Leaky pipes can be made from waste tyres

Incineration

• Incineration is usually done for 3 reasons:1. the destruction of waste 2. the production of energy from waste

3. the disposal of hazardous waste (scheduled waste)

• An incinerator is used to burn waste until it is reduced to ash.

Incinerator

Heat generated from incineration can be used to produce electricity (energy recovery).

• Advantages• Reduces the volume of waste for final disposal by about 90% • Yields five times greater useful energy per tonne of waste than

energy recovery from landfill • Suitable for many hazardous materials which should not be sent

to landfill

• Disadvantages• Costs are generally higher than landfill • Some emissions contain dangerous pollutants, such as dioxins • Highly toxic ash which still requires careful disposal

Waste hierarchy

Code of Practice 16:

Waste Management

Litter

• Minimisation• Packaging• Recycling• Reusing

Generator of waste is to:

• Minimise waste• Classify waste (hazardous / non-hazardous)• Segregate waste into recycling bins• Ensure appropriate storage on site• Identify appropriate waste management

location to dispose of the waste• Keep receipts from final destination (waste

management facility) for 3 years

A permit must be held by:

• A generator of hazardous waste • A collector / transporter of waste• Anyone who handles medical waste

• Permits to be issued by EAD or Sector Regulator

Before waste can be moved from homes and businesses to a landfill, be burned in an incinerator to make energy, or be recycled or treated, it needs to be

properly and safely packaged for transportation.

• The waste collector / transporter must:• Ensure all vehicles are constructed to prevent spillages• Ensure all containers are well secured on the vehicle• Have insurance to pay for clean-up in the event of an

accident• Incompatible wastes are not to be mixed

Mixed waste… non-hazardous

Should be sorted into:• Food / organic waste• Recyclables• Non-compostable waste

Landfills

• Must have controls over vermin, wind-borne litter, dust, leachates and gases

Government

• The government shall organise regular programs to collect household rubbish which is potentially hazardous, e.g. paints, oils, expired pharmaceuticals

• A manufacturer of HaxMats must keep a detailed manifest of all movements of substances for 3 years.
