c) Technical PerformanceIn IRIS <strong>the</strong> technical assessment of alternative systems focuses on <strong>the</strong> performance oflandfilling of garbage versus alternative waste treatment. The existing system, <strong>to</strong>ge<strong>the</strong>rwith Option 7, involves landfilling of domestic garbage hence <strong>the</strong>ir technical performance is<strong>the</strong> same. For Options 1 <strong>to</strong> 6, garbage is processed using an MBT process. Its technicalperformance differs <strong>to</strong> that of landfilling.In assessing relative technical performance, eight criteria are used. Results are summarisedgraphically in Figure 5.8. Landfills outperform MBT technologies for <strong>the</strong> following threecriteria:• Flexibility in Feeds<strong>to</strong>ck Quality: Landfill technical performance is not impacted by <strong>the</strong>composition of incoming wastes. MBT technologies may require quality control,removal of contaminants and some blending for optimal processing.• Staffing: For landfilling, relatively small numbers of staff are required and <strong>the</strong>technical skills required from staff are relatively low and are readily available locally.• Operational Reliability: Landfills have high operational reliability, reference facilitydata indicates high availability over long periods of continuous operation.MBT processing outperforms landfilling for <strong>the</strong> technical criteria of System Modularity;Process Control; Efficiency in Waste Reduction; and Area Requirements. Both technologiesperform equally under <strong>the</strong> technical criterion of Proven Technology.8Relative Performance6420Landfill (Existing, Option 7) MBT (Options 1 - 6)Flexibility in Feeds<strong>to</strong>ck QualityProcess ControlProven Technology / Reference FacilitiesArea RequiredModularity of SystemStaff RequirementsEfficiency in Waste ReductionOperational ReliabilityFigure 5.8: Relative Technical Performance<strong>Liverpool</strong> <strong>City</strong> <strong>Council</strong>46Waste Avoidance and Resource Recovery <strong>Strategy</strong>
