The London Borough of Hounslow wanted to bring their collection service back ‘in-house’ to their local authority trading company Recycle 360. In order to do so, they asked us to develop conceptual designs for their new waste transfer and processing facility.
We were commissioned with a brief to develop a kerbside-sort waste transfer station on an as-yet undeveloped site. We were allotted a specific space at the top of the site which gave us a determined size for the operation.
Once the size of the proposed site was finalised, our team began the design process. This initially required our modelling team to project recycling tonnages by separate streams to allow for 35,000 tonnes a year of material to be processed to ensure that the site would have enough capacity well into the future.
Our consultants used this calculation, combined with our depot builder model, to determine how big each of the bays would need to be to accommodate each material stream, taking into account the maximum period that each bay would be required to hold material for.
This work allowed our waste team to draw up an initial design for the site. This included a series of bays for card, paper, glass, mixed recyclate and metals and plastics, as well as sorting technology for the separation of metals and plastics into separated streams of plastic, steel and aluminium, and baler and a storage area for baled materials. Our team worked closely with Hounslow through a series of workshops to ensure that the design met all of their needs, and incorporated their amends into a finalised layout for the site.
The final conceptual design was then presented to Hounslow, along with an operational plan which detailed how the site would work in practice. This included:
- Swept path analysis, to confirm how vehicles would move around the site safely;
- The safety methods in place to ensure the smooth running of the site; and,
- Design constraints of the building size and operation.
As well as undertaking the design of the site, our waste team also coordinated its environmental permit, including developing an innovative Fire Prevention Plan (FPP) which was operationally specific to the site and tailored to the requirements of the transfer station.
Our final layout was then used by a leading engineering firm to develop planning applications and construction drawings. The waste transfer station has been in operation for over year, and was recently shortlisted in the Health and Safety Initiative category of the MRW National Recycling Awards for its fire safety measures.
Senior Consultant Sophie Crossette said:
“It was great to work with LB Hounslow to develop this site layout which provided a high-level of operational efficiency during the vehicle tipping process. It’s fantastic to see the site providing an essential service for the authority.”
A representative from the London Borough of Hounslow said:
“As part of our commitment to be cleaner and greener, we invested in our new state-of-the-art facility, with the aim of increasing recycling whilst generating revenue which can then support the Council’s frontline services. The Eunomia team provided us with comprehensive guidance and support throughout the project which was invaluable in enabling us to have a customised solution that met our needs.”
We also went on to support the procurement of the sorting and baling equipment required for the transfer station.
