Lakeside EfW Overview• Lakeside EfW Ltd is a joint venture with Grundon andViridor – leading UK recycling, renewable power andwaste players• Cost to build the plant: £160M• Design life: 25 years• Capable of treating 410,000 tonnes of waste per year• 37 MW capacity - equates to generating 250,000 MWhof electricity annually to the national grid• Lakeside EfW is privately funded and therefore thecost to the tax payer is nothing.• Created 46 new jobs

The Waste Hierarchy and ResourceEfficiency• Waste Hierarchy: Reduce, Re-Use, Recycle,Recover, Dispose• Grundon and Viridor – recycling-led service providers• Facility inputs from local authorities and businessesacross SE England – delivering landfill diversion andimproved resource efficiency• Lakeside recovers energy from non-hazardousresidual (post-recycling) waste only• New generation plant – safe, robust and efficient• CHP-ready

•Two process streams - throughput of 27 tonnes of waste per houreach.•Each stream will produce approximately 5.5 tonnes of bottom ash,and 1 tonne metals - re-useable commodities•Ash from the Flue Gas Treatment (FGT) system is approximately 0.9tonnes per hour (c.24 tpd) - classed as hazardous waste - taken fromsite, neutralised and landfilled.•95% of input produces energy or is recycled•

Environment• State-of-the–art engineering, monitoring and environmentalcontrol systems• Emissions controlled and monitored by Lakeside EfW• Also monitored and regulated by the Environmental Agency.• Emissions from all EfW plants must comply with the WasteIncineration Directive (WID) – do not compromise local airquality standards.

Monitoring Lakeside EfWThe plant is designed to meet the requirements of the WasteIncineration Directive (WID) as a minimum for release.Abatement equipment is designed to reduce emissions:-– Lime to remove acidic gases such as HCl, SO 2 and HF– Activated Carbon to reduce dioxins, PCB's, PAH's,mercury vapour and heavy metal salts.– The final stage is a bag filter to remove particulates– NO x removal is by ammonia injection into the furnaceto reduce the NO x to N 2

Monitoring Lakeside EfWThe plant will not continue to operate if:• emission limit values are exceeded for a period ofmore than 4 hours• Continuous monitoring equipment is out of servicefor more than 4 hours• Cumulative duration of abnormal operation exceeds60 hours in either of the above cases, calculatedover one calendar year.• Total particulates shall not exceed 150 mg/m 3• Total particulates half hourly limit 30 mg/m 3 or 10mg/m 3 daily average
