Leading supermarket chain diverts food waste from general waste

SUEZ recycling and recovery UK has been working with one of the UK’s leading supermarket brands as its waste and resource management partner since 2012. SUEZ provides collection and disposal services for the general waste, food waste and dry mixed recycling waste streams. The contract portfolio includes over 150 sites that are comprised of large retail outlets, distribution centres and service centres.

The mission

To provide an alternative solution for the disposal of food waste from the stores.

Our solution

When SUEZ first partnered with the supermarket, there was no reverse logistics operation in place at any of their stores in South West England.

Reverse logistics is the process of diverting goods from their typical final destination when there is an opportunity to capture any remaining value through another process before proper disposal.

SUEZ designed a solution for food waste recognising that a change from an individual store-side collection service to a backhaul system would achieve substantial cost savings, along with a significant decrease in environmental impact due to reduced vehicle movements.

In order to create the new process, SUEZ worked closely with the customer and the logistics partner – starting at the store and going right the way through to the disposal method via anaerobic digestion. During implementation changes to the store, processes were required. However, these were limited as much as possible to minimise the impact on the customer’s existing day-to-day operations.

Food waste collection system at retail park sites

Due to the nature of stores positioned at retail parks, they required a different solution for food waste; reverse logistics was not an option due to the far smaller volumes involved. A store-side collection model (involving both internal and external bins) was designed and implemented in collaboration with the customer and two facilities management companies (for catering and cleaning).
The results

The customer benefitted from a reduction in costs of 48%, equating to approximately £170,000 annually.

 

The new system was implemented effectively via a communications campaign to ensure that all staff involved in the process understood how it worked and what was required of them. In addition to the cost-savings, the carbon footprint has also reduced as a result of fewer vehicle movements and use of reverse logistics capacity, which would otherwise have been wasted.

 

As a direct result of this new system for food waste, approximately 150 tonnes per year is diverted from general waste, generating cost savings of £10,000. This represents an improvement in environmental performance by capturing this material for anaerobic digestion.

 

The backhaul system was highly successful, having initially been designed and implemented for food waste across the South West it can now be used as replicable model. The customer can apply the same process to materials such as card and plastics in order to achieve even greater savings in transport cost, environmental footprint and overall efficiencies in its recycling regime.
