Cleaning needs to be carried out in such a manner that is effective, efficient, without causing damage to personnel, equipment or surfaces and without causing cross or re-contamination and where cleaning and disinfection controls a hazard, it also needs to be validated.
As part of Holchem’s drive to provide a full range of hygiene solutions, we utilise bespoke programmes to make sure our customers are attaining the best level of clean, at the best value.
Cleaning methods need to be reviewed when changes are made which affect risk or process or in the light of new developments, such as cleaning detergents or cleaning tools. Such reviews can be used to identify opportunities for improvement, but must be carried out against clearly defined objectives; for instance: to improve the efficacy of the clean, to provide a reduction in the cost of cleaning or reduce the cleaning time, allowing a greater process plant up-time. For cleans that have been validated, such optimisation must maintain the validated objectives of the clean.
Once the optimisation objective has been met, the changes made must be recorded together with the validation results. This ensures that if any subsequent challenge arise, we can identify where in the process the issue manifested and if necessary the original procedures can be restored.
We work closely with our customer and utilising benchmarking models, we establish the performance of the current cleaning programme before any change, and monitor the performance of the new programme following any changes. Where sites have CIP sets with little or no capability of recording process variables, such as conductivity, temperature or flow rate, Holchem install data logging instrumentation to allow subsequent analysis of the cycle.
Holchem work closely with our customers utilising ‘cost of clean’ benchmarking models and in the case of CIP data logging systems. Our ‘cost of clean’ model provides an easy to use tool for our customers to calculate the overall cost of a clean, taking into consideration detergent, disinfectant, labour, energy, water and effluent. Once the cost of cleaning for an operation has been determined, the model allows the user to create various scenarios to determine where potential savings can be made, or to benchmark against other areas or sites.
