Braintree District Council asked us to undertake a full review of their glass bring site network to identify potential savings in the service they provide. Our review included a full assessment and modelling of three main options. We looked at the impacts of: making modifications to the existing service (including out-sourcing the service); reducing the network to only those which generate income; reducing the network to a small number of ‘super’ sites. The last two options were modelled with and without using bin sensors.
The aim of the project was to identify the potential savings to be made by modelling a range of different options. From this, to then identify the optimum model for the council to consider.
We identified the current land ownership, facilities, and access arrangements for the existing network. We identified the location and throughput at sites within a reduced network of income-generating sites. And we identified an optimal number and location of Super Sites, taking account of current tonnages and expected throughput, and identifying the optimum collection route for the Super Sites.
We conducted a cost benefit analysis for the options, including consideration of identified risks such as potential loss of income.
We identified collaborative working opportunities with local businesses and Parish Councils to see whether an incentive scheme to host a Super Site was required.
We assessed the impact that housing and associated waste growth might have on the network, accounting for the council’s Local Plan and the longer-term aspiration for North Essex Garden Communities.
We found that there are significant increases in income to be realised in all three scenarios we reviewed.
Overall, the results show that the optimum bring site service delivery scenario for Braintree District Council is the outsourced option. This realises an additional income generation in the region of £91,515 p/a above the current baseline, although a procurement exercise will need to be undertaken to establish exact contract costs, and therefore exact savings to be realised. In addition, the council will save up to £175,598 p/a in their current service delivery costs, although it should be noted that an annual contingency sum should be retained to cover cleansing costs during peak periods and that some management costs would remain (covering contract management and resident enquiry / complaint handling, for example).
