The proposed facility
The proposed design and site layout will include a range of environmental and safety controls.
All vehicles would be required to weigh in and out. Once they have entered the building all the loading and depositing manoeuvres take place within the building. Lorries would access the main building via roller shutter doors which would be closed at all other times.
Shredding of bulky waste would take place within the building rather than outdoors as currently happens. The vehicles for the bulky waste and shredding will exit via a second roller shutter door would then open to allow the vehicle to exit the building and then close afterwards.
Food waste and green waste will have a separate entrance and exit on the south/south western side of the main building. Vehicles leaving the food and green waste area will have to exit over the wheel wash prior to joining back on to the main route.
All vehicles would be required to weigh out on the outbound weighbridge prior to exiting the site.
A ventilation system and odour abatement technology would be provided to reduce the escape of odour.
Some changes to the ancillary buildings are also proposed to provide a modern and comfortable space for people working at and visiting the site:
- A new contractor’s office and staff welfare facilities (3m tall, 9.6m x 12.0m)
- The existing bungalow (3m tall, 9.6m x 18.0m) will be refurbished with capacity to host Buckinghamshire County Council officers and site visitors, and the existing workshops (~6m tall, 6.2m x 19.6m) will stay the same.
- The car park will also be reorganised.
Operational hours are proposed to be between the hours of: 7.30am to 6pm Mondays to Fridays, 8am to 3.30pm Saturdays, 8am to 1pm on Sundays, no working on bank and public holidays.Operational hours from 7.30am to 5.30pm may be required, but on no more than 20 Saturdays per year; to compensate for Public, Bank Holidays and unplanned disruptions in service. These are ‘catch-up’ Saturdays allowing for District Council collections that do not take place on bank holidays and public holidays (including any new declared by Government) and contingency for District Council’s service disruptions, including bad weather.
Looking ahead: population growth and contingency
The new building needs to be sized carefully to ensure it stays fit-for-purpose and is good value for money. To calculate the size, we looked at how much food, garden and bulky waste material is currently handled at the site and added a small fraction to accommodate for natural population growth (as detailed in District Local Plans).
An amount of contingency storage capacity is also required, in the event of bad weather or a processing backlog, or when the end destinations for the waste are not available for a period of time. This enables extra storage within the building on a short-term basis, over and above what normally arrives. To accommodate for the extra stored (short-term) waste, we need to make sure the building is large enough for it, plus the normally collected waste at any point in time. The planning application needs to include the total tonnage figure.
Once the building is open there will be no change in the traffic volumes. However, over time there will be year on year increase in line with population expansion. Occasionally, when contingency storage is required, a spike in traffic will occur.
Creating a safe, healthy workspace
The building has been designed with enough capacity for existing activities to continue safely.
Dimensions: 60m wide x 91.2m long x 13.66m tall at highest point.
Protecting the environment and wildlife during construction
The design and construction of the facility will be guided by ecologists to ensure the protection of the local environment and wildlife. Any bramble scrub removal will take place outside of the main nesting season for birds (March to August), and if any active nests are found, they will be protected and remain undisturbed until the young birds have fledged.
To protect the local bat population, sensitive lighting will be used to avoid light spill onto adjacent off-site bat flight corridors and foraging areas to the north and east of the site. Appropriate measures will also be used to protect reptiles such as slow worms during construction.
