|Description of the Challenge||Large-scale process industries, such as agrofood, milk and beverage processing, are required to deploy the best available technology to reduce their impact on the local environment and reduce their contribution to sectoral and national carbon emissions. Current CIP systems consume large quantities of energy, water and cleaning chemicals and generate large quantities of effluent requiring expensive treatment in wastewater treatment plants. Reducing the resources used by CIP systems is the key challenge.|
Approximately one third of the water consumed in a modern milk processing plant is used by Cleaning –in-Place (CIP) systems for the cleaning and sanitising of milk contact surfaces; vessels, pipelines and equipment. Large quantities of a range of expensive cleaning and sanitising chemicals are used in the make-up in of cleaning solutions in CIP plants. Post cleaning the spent cleaning solutions have to be neutralised and broken down in effluent treatment plants.
|Fundamental requirements and constraints||
A prerequisite for such a closed loop system would be that it was robust enough to operate continuously on-demand under the high temperature, pH and high circulation flow rates of a central CIP system and have a low maintenance requirement.

|Name of the organisation||Lakeland Dairies|
Lakeland Dairies, a major dairy processing co-operative, operates within a nineteen county catchment area across the northern half of the island of Ireland. The Group processes about 1.8 billion litres of quality milk annually into a range of value added dairy foodservice products and functional dairy food ingredients.
