In 2014, we completed the second phase of our new facility in Suzhou, built to manufacture some products previously made in Florida, US and Hull, UK and also designed to accommodate future growth requirements.
Designed for lean manufacturing, the plant will use 32% less energy/m3 of manufacturing space compared to our older facilities. Some of this saving was achieved by using evaporation cooling towers for the dominating clean room cooling requirement. Although this resulted in 56,000m3 of additional water being consumed, the overall environmental impact is lower.
Impacts of the transition
Ensuring continuity of supply to our customers requires an overlap of new plant commissioning with ongoing manufacturing in existing plants.
This resulted in an additional 9.9GWh of electricity consumed in 2014 compared to 2011. A further2.6GWh was averted by additional energy saving projects.
The clean room space, built with future growth in mind, provides optimum space from operating and energy perspectives. However, in the short term, until it is fully utilised means the total energy consumed per unit of output is sub optimum.
