What goes into landfill?

What materials can be recycled?

Paper household & office

Household waste

Organic wasteOrganic 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.

Organic waste kitchen & garden

Solution to organic waste in AustraliaThe 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.

Construction debris

Steel & aluminium

Waste tyres

Leaky pipes can be made from waste tyres

IncinerationIncineration 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).

AdvantagesReduces 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

DisadvantagesCosts 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

LitterMinimisationPackagingRecyclingReusing

Generator of waste is to:Minimise wasteClassify waste (hazardous / non-hazardous)Segregate waste into recycling binsEnsure appropriate storage on siteIdentify appropriate waste management location to dispose of the wasteKeep 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 wasteAnyone 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 spillagesEnsure all containers are well secured on the vehicleHave insurance to pay for clean-up in the event of an accidentIncompatible wastes are not to be mixed

Mixed waste non-hazardousShould be sorted into:Food / organic wasteRecyclablesNon-compostable waste

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

GovernmentThe 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.
