Increased diversion can be achieved through a range of possible initiatives including:Possible Initiative 1: Increase Dry Recyclables RecoveryA recent survey of resource recovery and environmental issues carried out by Council (IRISResearch; 2004) identified there is some confusion amongst Liverpool residents on what canand cannot be placed in recycling crates. A number of residents also indicated that the sizeof the crate inhibited their recycling behaviour. Measures that could be undertaken byCouncil to increase recovery of dry recyclable material include:• Foster increased resident participation in recycling, through further education andawareness;• Increase the range of materials that can be recycled (for example, more plasticsgrades); and• Kerbside recycling service enhancement (for example, provide mobile receptacles ofincreased capacity for collection of dry recyclables).Possible Initiative 2: Garden Organics RecoveryIntroduce regular (fortnightly) collections of garden organics (recovery rates are maximisedwhere rigid mobile containers are provided for collections).Possible Initiative 3: Alternative Waste Treatment 2Process collected garbage through an Alternative Waste Treatment facility instead of directdisposal to landfill as currently occurs, thereby providing further opportunity to achieveimproved sustainability outcomes including:• Reduction in the quantity of material for final disposal;• Waste stabilisation to reduce gas formation and leachate pollution; and• Production of outputs (organics / energy / gas / recyclables) that can be beneficiallyre-used.2Alternative Waste Treatment (AWT) are processes that:• Reduce the quantity of material for final disposal;• Stabilise the material to reduce gas and leachate formation; and• Produce outputs (energy / compost / oil / gas / recyclables) that can be beneficially re-used.AWT processes can be categorised under the following headings:1) Mechanical Biological Treatment (MBT): Processes that incorporate mechanical sorting and separation of waste into predominantlybiodegradable and non-biodegradable streams. The biodegradable stream is subject to a biological treatment process (for examplecomposting and/or anaerobic digestion). The “non-” biodegradable stream can be further sorted to extract recyclable materials.2) Thermal treatment (Energy from Waste - EfW): Processes that use heat to decompose waste and produce a stable residue fordisposal. Energy is recovered during processing in the form of heat and/or electricity.3) Combinations of bothLiverpool City Council18Waste Avoidance and Resource Recovery Strategy
