What does Cleaner Production mean? All manufacturing operations require energy for operations and or create air pollution. An independent audit of the energy consumption and processes in a production facility will identify areas for improvement of the energy efficiency.
If the facility owner implements the corrective measures the operating cost will be lower, and environmental impact of the facility will be reduced, so we have cleaner production. Shameless plug for my firm Kelcroft is a registered consultant for the Hong Kong Cleaner Production Programme called CP3 (refer image).
Need an example to clarify? Right let’s take a look at the injection moulding process. Like many processes the press creates heat energy therefore to cool the machine moulds cooling water is needed. It circulated through the injection moulding machine, and the heat rejected outside the building typically using a cooling tower. However, often the cooling towers are out of sight (and out of mind) they are not properly designed and not regularly maintained. Therefore the effectiveness of the whole process deteriorates causing excessive energy consumption.
This deterioration process does not occur overnight! No, it is a slow steady process. These apparently insignificant efficiency losses combine lowering the cooling capacity of the cooling tower installation until one day the injection moulding machine malfunctions, and the facility manager then replaces the whole cooling tower. An energy auditor familiar with cooling tower operation could identify the fix before a minor problem becomes a catastrophe.
