Site & location: Land at Hams Hall National Distribution, Faraday Avenue, Coleshill, B46 1AL. [Grid ref: 419861.292156]. See plan in Appendix A 1 of 54 03 Hams Hall National Distribution Centre – Regulatory Committee 07.02.2017 Recommendation That the Regulatory Committee authorises the grant of planning permission for the construction and operation of a renewable energy centre (Use Class sui generis) for the recovery of energy (heat and electricity) from non- hazardous residual waste using an advanced conversion technology (gasification), with the associated plant and infrastructure, vehicular access and landscaping subject to the conditions and for the reasons contained within Appendix B of the report of the Strategic Director for Communities. 1. Application Details 1.1 This application seeks planning permission for the construction and operation of a Renewable Energy Centre (REC) on land at Hams Hall Distribution Park. The purpose of the REC would be to generate energy (heat and power) from non-hazardous residual waste. The proposed development would use an Advanced Conversion Technology (ACT) process known as gasification. Gasification is a process whereby the fuel source (in this case residual waste) is heated to very high temperatures causing the materials to breakdown whilst also generating a gas which when burnt off in a boiler creates steam, which in turn drives a steam turbine to generate electricity or exported as heat. 1.2 The proposed REC would have a capacity to produce around 14.5 MW of electricity plus around 1.5MW of heat. The proposed facility would be a form of Combined Heat and Power (CHP) plant. 1.3 The proposed Renewable Energy Centre would have a capacity to process up to 150,000 tonnes of non-hazardous residual waste per annum (waste left over following the practical removal of recyclable materials (pre-treated waste) that may otherwise be disposed of at a landfill site or exported to a similar facility abroad. The residual waste feedstock would predominantly take the form of Refuse Derived Fuel (RDF) which is a product derived from residual waste. 1.4 The application site extends to 1.96 hectares and is located within the western end of Hams Hall Distribution Park. 1.5 The development would comprised of the following key elements: 1.6 The main building would be located centrally within the application site and would measure 87.96 metres by 72.7 metres by 24 metres in height at its highest point. This building would accommodate the majority of the processing plant including waste reception hall, waste bunker, shredder, fuel bunker and three line ACT (advanced Conversion Technology) processing plant and associated feed water tank, control room, workshop and crane service area. The fuel bunker would have a capacity sufficient to store 4 days of waste feedstock. The main building would be finished primarily in profiled metal sheets (walls and roof) incorporating vents and louvres, with walls coloured in graded grey bands which would lighten in shade towards the roof. 2 of 54 03 Hams Hall National Distribution Centre – Regulatory Committee 07.02.2017 Vehicle access points into the building would be fitted with fast acting doors. 1.7 The facility would require a flue stack (chimney) which would be located towards the rear of the main building. The flue stack would measure 2.8 metres in diameter and stand 52 metres in height. The flue stack would be coloured grey. A walk around metal platform would be located towards the top of the flue stack to allow continual air quality monitoring access. 1.8 A number of structures comprising of silos and filters would be located at the rear of the main building. This would include: two lime silos measuring 4.1 metres in diameter by 18.7 metres in height, a carbon silo measuring 4 metres in diameter by 18.7 metres in height, two dust filter silos located within a framework measuring 10.5 metres by 5.15 metres by 19.5 metres in height and three gas flue filters each measuring 5.6 metres by 25.7 metres in height. 1.9 A Turbine Room, which would accommodate the turbines used to generate energy, would be housed in a separate building located to the rear of the site. The Turbine Room would measure 30 metres by 15 metres by 15.6 metres in height. 1.10 Air Cooled Condenser Fans (ACC) contained within a structure measuring 39.62 metres by 15.76 metres by 23.4 metres in height would also be located towards the rear of the a site. 1.11 A Sub Station, which would allow electricity produced on site to be fed into the National Grid, would be located towards the rear of the site. The Sub Station, measuring 48 metres by 25 metres and enclosed by 2.4 metre high security fencing, would consist of a transformer and electrical connectors standing up to 3.5 metres in height and a metering and control room measuring 3.5 metres by 5 metres by 2.8 metres in height. 1.12 Further ancillary buildings/structures would be located within the facility. This would include: an ash bunker measuring 12 metres by 10 metres by 5 metres in height, a fire water tank measuring 17 metres in diameter by 6.75 metres in height, a Pump Room located to the side water tank measuring 6.06 metres by 4.59 metres by 3.2 metres in height, a gatehouse/weighbridge office measuring 4.86 metres by 3 metres by 2.95 metres in height. 1.13 The yard area would include vehicle circulation space including sufficient space to allow for queuing of vehicles within the site and a carpark designed to accommodate 19 vehicles. 1.14 The facility would be enclosed with 2 metre high security fencing. 1.15 The external areas of the facility would be lit with a series of building mounted and pole mounted lighting. 3 of 54 03 Hams Hall National Distribution Centre – Regulatory Committee 07.02.2017 1.16 The facility would be accessed directly from Faraday Avenue as the site is currently. The existing access would be redesigned and reconstructed to allow vehicles a safe left-in and left-out priority access and egress from the site onto the highway. This would create sufficient width and capacity to allow vehicles to pass one another safely when entering and leaving the site. 1.17 A strip of landscape planting measuring between 5 and 10 metres in width, including native tree and shrub species, would be provided along the frontage of the site. 1.18 Waste and RDF is likely to be delivered to the site in both refuse collection vehicles (RCV) and articulated bulk haulage vehicles. The facility is likely to generate up to 88 HGV movements (44 in/44 out). These movements would include waste imports, deliveries of lime, carbon etc and removal of metals and ash, etc from the site. 1.19 Once operational the facility would operate as follows. Upon entering the site HGV’s loaded with residual waste/RDF would be directed to one of the two weighbridges to be checked in. Vehicles would then be directed to the waste reception hall within the main building for unloading. Once the vehicle is inside the waste reception hall fast acting doors would close. The waste reception hall would operate under negative pressure to draw in and contain odours. Once unloaded, waste which has arrived pre-processed into RDF would be transferred by overhead crane into the fuel bunker. Residual waste requiring processing would be transferred by crane into a shredder before being passed across a magnet to remove metals. The overhead crane would then deliver the residual waste to the fuel hopper of the ACT unit. The REC facility’s fuel bunker would sufficient storage capacity to allow the facility to continue operating for up to 4 days without a waste delivery. From here the residual waste enters the thermal conversion process. 1.20 The thermal conversion/gasification process takes place in two stages. The first stage, the gasification process does not burn (combust) residual waste but rather heats the materials at high temperatures until their composition breaks down. The output from the gasification process is a synthetic gas called ‘syngas’ and bottom ash. The second stage involves oxidation/combustion of the syngas within a high temperature oxidation unit. A heat recovery steam generator (boiler) would then utilise the heat produced to generate steam which in turn would either be used for the delivery of heat or for the production of electricity. The bottom ash generated would be removed from site to a licenced waste management facility for recycling or disposal. 4 of 54 03 Hams Hall National Distribution Centre – Regulatory Committee 07.02.2017 1.21 The REC would operate 24 hours per day 7 days per week throughout the year, except during shut downs for maintenance.
