["The installation is an Energy from Waste (EfW) plant which can process up to 467,082 tonnes of residual (non-recyclable) Commercial and Industrial and Municipal waste per annum, leading to a net export of approximately 37 MW of electrical energy to the National Grid. The facility comprises two identical moving grate incinerator combustion lines with a combined capacity of approximately 50 tonne/hr of waste of an approximate 9.8MJ/kg calorific value. The waste is delivered to the site by road, and rail by a dedicated onsite railhead served by two gantry cranes. The plant has two auxiliary burners to support start-up and shutdown on each incineration line, and a stand-by diesel generator to support emergency shutdown in the event of power failure.\n\nThe incinerator bottom ash (IBA) waste on the site is quenched to control dust fugitive emissions and transferred by covered conveyors to the onsite bottom ash recycling plant. The bottom ash recycling plant uses magnets, eddy current separators and a trommel to recover ferrous metals and non-ferrous metals from the bottom ash.\n\nHazardous air pollution control residues (APCR) from the flue gas treatment plant are collected and removed offsite for treatment. The treatment process involves the removal of contaminants and reuse of the fine ash material in a lime rich filter cake product for land remediation.\n\nSNCR (ammonia) is used to reduce emissions of oxides of nitrogen, lime to reduce acid gas emissions and carbon injection for reduction of organics including dioxins and PAH emissions, and heavy metals. Bag filters within the flue gas treatment plant remove dust (particulates) from the emissions to air. The treated emissions to air are released through two 118 metre stacks comprising two flues that run the full length of the stack (one for each incineration line). A continuous emissions monitoring system (CEMS) is installed, as required by the permit, to provide continuous analysis of oxides of nitrogen, sulphur dioxide, carbon monoxide, carbon dioxide, hydrogen chloride, particulates, total organic carbon, ammonia and nitrous oxide emissions to air from the two stacks. \n\nThe main emissions to air from the site are the combustion gases, predominantly carbon dioxide and water vapour. Trace gases present include oxides of nitrogen, sulphur dioxide, hydrogen chloride, ammonia, dioxins and furans, dioxin like PCB's and  polyaromatic hydrocarbons. Very low levels of particulates and some heavy metals may also be present. There are no emissions from the process to controlled waters. Water discharge of uncontaminated surface (rain) water is permitted.\n\nThe Severn Estuary SAC, SSSI, SPA and RAMSAR sites are within 10km of the site, along with the River Wye and Avon Gorge Woodlands.",null,null,null,null,null,null,null,null,null,"Include summary of plant design, design capacity, no. of combustion lines, electrical and heat capacity and any other general information that describes the facility, its location and purpose "]

["Activity listed in Schedule 1 of the EP Regulations\nS5.1 A1 (b) The incineration of non-hazardous waste in a waste incineration plant with a capacity of 3 tonnes per hour or more.\nFrom receipt of commercial, industrial and municipal waste by road and/or rail to storage of gas oil auxiliary fuel, to incineration of waste and removal of ash. The receipt, handling, storage, processing and treatment of incinerator bottom ash only from within the installation.\n\nDirectly Associated Activities\nThe generation of up to 39 MWe electrical power, with approximately 37 MWe for export to the National Grid, using a steam turbine from energy recovered from the flue gases. From receipt of commercial, industrial and municipal waste by road and/or rail to storage of gas oil auxiliary fuel, to incineration of\nwaste and removal of ash. The receipt, handling, storage, processing and treatment of incinerator bottom ash only from within the installation.\n\nStandby diesel generator for providing emergency electrical power to the plant in the event of supply\ninterruption. From receipt of diesel fuel to production of electricity for controlled shutdown of incinerator in the event of power failure at the site.\n\nRailhead; operation of designated railhead for the receipt of waste for thermal treatment and the potential dispatch by rail of recycled bottom ash as a secondary aggregate. From receipt of waste to the potential loading of processed IBA, limited within the site boundary.\n\nPlant Description\nIncoming contract waste is delivered to site by rail with each train carrying approximately 1,000 tonnes of waste in 78 containers. Each container is transferred by gantry crane to roll on/off vehicles and taken to the Tipping Hall for unloading into the waste bunker. Third party waste is received by road, checked in, weighed and delivered into the reception hall by Roro’s, refuse collection vehicles and bulk transport vehicles.\n\nRECEPTION HALL\nA large reception hall allows for vehicles delivering waste to the site to manoeuvre and tip waste safely. The tipping hall is constructed above ground level as part of the sites flood protection strategy. HGV access to and egress from the Tipping Hall is via ramps on the south and north sides of the building. Air needed for combustion is drawn into the furnace from here (above the waste bunker) so that negative pressure is maintained in order to avoid odour and dust escaping the building. The tipping hall also includes an automatic dust and odour suppression system.\n\nWASTE BUNKER\nWaste vehicles reverse to a wheel stop and tip their loads into a large concrete bunker. The waste cranes operate over the waste bunker automatically to mix the waste to improve the homogeneity of the incinerator feedstock and feed the waste hoppers for each incineration line. Manual control by crane operators is carried out as and when required. Inspection of wastes received is carried out by the Day Operations team to look for unsuitable material and non-permitted wastes to be removed.\n\nCONTROL ROOM\nThe plant’s control room contains the Distributed Control System (DCS) which centralises the operation of the plant, and all equipment, including the grab cranes used to mix and load waste into the hoppers that feed the incineration lines. All on-site functions are monitored automatically and manually. Its systems verify in real time that equipment is functioning properly, continuously monitor the combustion processes, flue gases, and maximise the efficiency of the entire EfW process.\n\nGRATE AND BOILER\nWaste is lifted into the feed hoppers by the waste cranes. From here it is dropped into the furnace feed chute and then is introduced onto the grate system by hydraulic ram feeders for incineration. Auxiliary burners are used at start up and shut down, and can be used to help keep the furnace temperature above 850°C if required. The plant has two auxiliary burners per incineration line. The thermal energy released from the incineration of waste is used to convert water to super-heated steam through the boiler and 4th pass superheater. At high pressure, this steam drives a turbine to generate electricity.\n\nELECTRICITY GENERATION\nThe turbine drives a step down gearbox, which in turn drives a generator. Electricity is generated at 11kv, with electricity production of 312,000 MWh/annum (based on 39MW and 8,000 operating hours) and exporting approximately 296,000 MWh/annum to the national grid.\n\nINCINERATOR BOTTOM ASH (IBA)\nAsh left on the grate after incineration falls through the grate riddling's or off the end of the grate, is combined with boiler ash produced in the superheater and passes into the bottom ash extractor. The bottom ash extractor contains water to quench the ash and to provide an air seal for the furnace. The material is removed from the bottom ash extractor by a drag conveyor passing the material onto the vibrating fingers for removal of the oversize metal content. The oversize metal drops into a skip for collection and the remaining IBA material is dropped onto a conveyor for transport to the on site IBA recycling plant. Up to 100,000 tonnes per annum of IBA is produced and then processed on site by the removal of ferrous and non-ferrous metal, stabilised and separated into fraction sizes prior to the export from site of the recovered aggregates and metals for re-use.\n\nAIR-COOLED CONDENSERS\nAfter exiting the turbine, the steam is cooled and condensed back into water through air cooled condensers. This recovered water is collected in the condensate tank, treated and returned to the feedwater system to supply the boiler drum and to produce more steam, thus reducing consumption of mains water.\n\nEMISSION CONTROL\nThe flue gases from the incineration of waste are subject to a rigorous cleaning process involving ammonia for removal of Nitrogen Oxides (NOx) by selective non-catalytic reduction (SNCR). A DyNor (Dynamic NOx Reduction system) is used to optimise NOx reduction and reduce ammonia slip by altering the ammonia injection point into the furnace, dependent on the temperature profile, so the injection takes place where the SNCR reaction will be most effective. Lime and powdered activated carbon is injected into the reactor where the lime removes acidic gases such as sulphur dioxide (SO2) and hydrogen chloride (HCL), and the activated carbon removes heavy metals, dioxins and furans.\n \nAIR POLLUTION CONTROL RESIDUE (APCR)\nThe cleaned flue gases pass from the reactor through fine-fabric bag filters to remove solid particulates (dust). The bag filters become coated with lime and carbon and provides a further reaction surface increasing the effectiveness of the carbon and lime. When the pressure differential between the inside of the fabric filters becomes too great, a jet of compressed air is used to remove some of the reagents and ash caking the outside of the bag filters. Some of this material is recirculated back into the reactor where atomised water jets reactive the reagents for further use in the reactor.\nThe remaining APCR collected from the bag filter housing contains ash particles from the incineration process, spent lime used in the flue gas treatment, salts and carbon dust. It is transported to and stored in two sealed silo’s until it is tankered away for recovery.\n\nCONTINUOUS EMISSIONS MONITORING SYSTEM (CEMS)\nThe flue gases are drawn through the flue gas treatment system by large induction fans which then vent and discharge the treated flue gases to atmosphere via the stacks. A continuous emissions monitoring system is installed on each stack to monitor these emissions. The data is used to make any necessary adjustment to reagent dosing to ensure compliance with permit Emission Limit Values (ELV’s). This data is relayed automatically to the control room and is under close observation by the Operations Team. The CEMS is subject to QAL3 calibration tests (zero and span checks) performed monthly by the maintenance team, and an external contractor carries out annual servicing, calibration and emission testing as required by the permit.",null,null,null,null,null,null,null,null,null,"Include summary of key processes and procedures such as (but not limited to); waste reception, control rooms, grate, bed and boiler, energy & heat  generation, cooling systems, residue management, emission controls, health and safety systems, maintenance"]

In addition to the typical scope of works and inspections, the major activities included boiler tube panel replacements on both lines (bullnose area for L1 and pass 1/2 dividing wall, upper header level for L2), bottom ash extractor chain replacement on L2 and full baghouse filter replacement and adjustment of chamber shut-off dampers on L2.\n\nNew projects also included the bottom ash drop-off chute modifications, installation of new boiler pressure testing points, ACC structural reinforcement improvements and biogenic C14 analysers and stackflow 200 probes.",null,null,null,null,null,null,null,null,null,"Include summary of key operational and/or maintenance activity undertaken in the year, such as any major component upgrades and/or replacements "]

["Summary of Residue Handling for the reporting year"]
[]
["IBA is the main residue by volume/weight associated with the burning of waste for energy generation. The IBA is the heavy ash produced by the combustion process that is discharged from the bottom of the furnace grate and the fine ash that passes through the moving grate to the bottom ash tank. The IBA at Suffolk represents approximately 21% of the annual mass of waste that is thermally treated by the incineration process. The plant therefore can produce up to 100,000 tonnes of IBA per annum.\nAPCR is the boiler ash that is produced in the furnace that is light enough to be carried through the boiler entrained in the flue gases. As it passes through the flue gas treatment (FGT) process, lime and carbon is added as part of the treatment process to remove acidic gases, heavy metals and other hazardous products of the combustion process including dioxins and furans.\nThis boiler ash combined with these reagents in FGT is referred to as Air Pollution Control Residue. APCR at Suffolk EfW represents up to 2.5% of the annual mass of waste that is thermally treated by the incineration process. The plant therefore can produce up to 12,000 tonnes of APCR per annum.\nIBA is sampled every two weeks for laboratory analysis and this is carried out in accordance with Environment Agency waste classification guidance. The two weekly samples include a partial hazard assessment, a further sample is carried out annually for full hazard assessment. This analysis and assessment is carried out to confirm the ongoing non-hazardous status of the IBA material. Additional sampling and analysis is carried out quarterly in line with permit requirements. The only emission limit value applied to the IBA is a 3% TOC limit. APCR analysis is carried out quarterly in line with permit requirements. Additional analysis of APCR was carried out during 2025 to udnertake a full hazard assessment to identify the hazard properties for this residue.\nThe IBA is treated by the onsite IBA recycling plant, operated by Blue Phoenix, to extract ferrous and non-ferrous metal for recycling, and to produce an IBA aggregate material to replace the use of virgin aggregate in construction projects.\nAll APCR material is treated for further use. It is removed from site and treated by Castle Environment at their site in Ilkeston.\nThe material is cleaned by their acid neutralisation process to reduce lime alkalinity to produce a non-hazardous solid filter cake. This process allows the material to achieve non-hazardous status and then it is re-used in land remediation where the residual lime can effectively remediate acidic land contamination from colliery spoils for example.

["Environment Agency explanatory note: The 10-minute average ELV is based on the “95th percentile”. In this case this means that 95% of the 10 minute averages in the relevant 24-hour period (i.e. 137) must be below 150 mg/Nm3, and 5% (i.e. 7) are allowed to be any value above 150 mg/Nm3. Whilst we expect operators to minimise CO emissions at all times, it is perfectly acceptable for the value of the maximum 10-minute average to be above 150 mg/Nm3, provided the 95th percentile ELV has been met for that period.
