Waste Processing


Bletchley landfill site lies 0.5km south west of Bletchley and 0.5km north east of Newton Longville near Milton Keynes, Buckinghamshire. The site is bordered by arable fields , restored industrial land and some suburban housing areas, and is bordered on the east by the Blue Lagoon Local Nature Reserve. The site is accessed from the west, via an access road off the A4146, Drayton Road.



  • Clay extraction and brick making commenced at Newton Longville during the early part of the 20th century.
  • Land filling with predominantly inert waste commenced by the start of the 1970’s and was operated by the then landowners London Brick Company.
  • Following the closure of the brickworks in 1984 Shanks acquired the site, and in 1989 sought revised planning permission to fill and restore the excavated site which was eventually approved in 2002. Approval was subject to new access being constructed to the east of the site to allow tipping in this area.
  • The consent comprises two planning permissions as the site falls within both Milton Keynes and Buckinghamshire boundaries.
  • [FCC] Waste Recycling Group took over ownership of the site and land filling activities in 2004, and the new access road was completed in 2007.
  • The nearest sensitive receptors to the site are;
  • Residential properties along Bletchley Road to the west.
  • Newton Longville to the south west.
  • Residential properties to the north backing on to the railway.
  • The Lakes Estate and Newton Leys development site to the east.
  • The Blue Lagoon LNR reserve to the north east.

Operations (Landfill)

  • Remaining void as of September 2012 was 17.1 m³, of which approximately 460,000 m³ is current operational void in Cell 7.
  • The site accepts approximately 65,000te of waste per month (roughly 200 to 250 vehicles per day).
  • Operational hours are from 7.00am to 6.00pm Monday to Friday and 7.00am to 1.00pm on Saturdays. Each Saturday following a bank holiday tipping is extended to 4.00pm for Council waste.
  • The waste that is delivered to the Bletchley landfill site comprises; industrial and commercial waste, household waste, transfer station waste, soils and other cover material.   During 2013 we expect to dispose of around 750,000 tonnes of waste at the landfill site.
  • Site front line machinery includes 1 x 50te compactor, 2 D6 bulldozers, 2 x 360 Excavators, 1x 963 tracked loading shovel, 1 x Bell dump truck and 2 x tractor and water bowsers.
  • The site employs 18 operational staff and also operates as a regional office where 15 FCC staff are based.

Operations (Materials Recycling Facility (MRF)


  • At FCC we are constantly looking to lessen the amount of waste that goes to landfill and to help this Bletchley landfill is building a materials recycling facility due to be open in April 2013.
  • Waste will be delivered over the weighbridge as normal and selected for diversion in to the plant where it will be stored in a waste bay before being loaded in to a shredder.  It will be screened and sorted to segregate metals, fines, aggregate, wood, plastic and WEEE.  The finished product will be 70% of the input volume and will be a bailed Solid Recovered Fuel [SRF].  The other materials can be recycled as appropriate.
  • Initially this facility should process 100,000 tonnes per annum.  We will be able to divert 100,000 tonnes of waste from the current landfill to the new MRF at Bletchley from the municipal, construction and industrial waste.
  • Waste acceptance at the facility will be in line with the landfill weighbridge hours detailed above
  • Operational hours at the MRF are from 7.00am to 10.00pm Monday to Friday and 7.00am to 8.00pm on Saturdays and Sundays.

Landfill Gas Generation & Leachate

  • All landfill sites naturally produce gas as waste degrades and breaks down. Made up mostly of methane, oxygen and nitrogen, this gas is captured for two reasons.
  • Firstly, it is a valuable source of green energy and can be used to generate electricity (see animation). The site controls gas and generates electricity via nine landfill gas utilisation engines and ancillary equipment connected to gas flare compounds.  Around 8.5MW of electricity is generated every day at Bletchley from burning gas. That’s roughly enough to power 7,600 homes.
  • Secondly, capturing the gas significantly reduces the smells it can carry. The process of extracting and using the landfill gas as fuel is carried out by Infinis ( ) at all of FCC Environment’s landfill sites.
  • A network of vertical 225mm and 160mm diameter wells (approximately 300) are installed across the site and collected via 160mm to 355m pipe work laid across the surface.
  • Leachate is pumped from wells across the site and collected in to three 50m³ storage tanks. From here it is pumped to a Leachate Treatment Plant on site where it is treated and discharged to sewer at a consented volume of 200 m³ per day.
  • The Leachate Treatment Plant has capacity to treat additional external leachate within this discharge volume.

Geology & Engineering Phasing

  • The site is located in an area where glacial till overlies Oxford Clay, Kellaways Sand, Kellaways Clay, Cornbrash Limestone, Blisworth Clay and Blisworth Limestone.
  • The landfill phasing comprises 12 areas and cells which have been filled progressively from the south west to north east of the site covering an area of approximately 91.5ha. A further 7 cells are anticipated.
  • Earlier engineered areas comprise a mix of clay lined non-engineered bases and seals and engineered bases and seals. Later areas and cells have been fully engineered including engineered capping.
  • Restoration of completed phases of the site has commenced and progressively follows completed operational areas. Approximately 40% of the site void has been filled and capped.

Future Development

  • A phase 2 extension to the MRF to increase the processing capacity to 200,000 tonnes per annum (Planning and Permit Approved)
  • Proposals for a single 87m wind turbine (Planning Submitted)
  • A wood shredding operation (Planning Submitted)
  • A Maize Anaerobic Digestion Plant (Planning Submitted)


  • We are working to a post settlement restoration scheme from 2003.  The scheme details a mixture uses including; low intensity grazing with potential for recreational use, scrub and rough grasslands, peripheral woodland, hedges, coppice and light woodland, agricultural grazing, footpaths, calcerous grasslands.

  • To date there has been some grass seeding and tree planting as the landfill has been progressively restored and capped.  We have also this year translocated some clay material from our neighbouring Taylor Wimpey site on to a capped area and we will trial how the local grasses grow on this area over the next three years.
