Predicting and Calculating Savings of Implementing Clean by Design's Ten Best Practices

Category Guidance for mills on energy/water management.
Published by:   Natural Resources Defense Council (NRDC)
Target Audience:  Textile mills
What will this resource help with? Follow NRDC guidelines on energy/water management in textile mills and applying them by using work sheets, checklists and calculation tables.  

The NRDC document on energy/water management guides mills through processes such as metering, leak detection, preventing unintentional water loss, generating savings through efficient water/energy usage and routine data recording and analysis. As the biggest energy conservation treasure in mills, condensate collection and recovery is broken down into three principles.  Since, dyeing and printing are the most water intensive processes in the textile industry, water reuse is a further topic. Furthermore heat recovery from hot water is highlighted due to the fact that about 20-30 % of the total energy in a factory is carried away by water. Boiler efficiency improvement, steam traps and steam system management, insulation improvement, heat recovery from hot air as well as electricity savings are detailed with regards to energy saving and management.

Throughout the document, calculations for potential savings for each step are given and are underlined by selected case studies. Additionally, key steps for evaluating program performance and achieving continuous improvements are presented. Practical work sheets and checklists promote a hands-on application of the document’s guidance.
