Energy conservation status in Taiwanese food industry

The food industry in Taiwan is labor intensive, the cost of raw materials is high, and there is much product diversification. Although this industry is primarily small and medium scale, it is a large user of electricity in Taiwanʹs manufacturing sector. The concentration of greenhouse gases (GHGs) from manufacturing activities and vehicle emissions has increased remarkably. Energy audits are a basic and direct means by which energy efficiency can be improved, energy consumption reduced, and carbon dioxide emissions inhibited. This work summarizes the energy saving potential of 76 firms and the energy savings implemented by 23 firms as determined by energy audit tracking and from the on-line energy declaration system in Taiwanʹs food industry. The results of this study can serve as a benchmark for developing a quantified list in terms of potential energy savings and opportunities for improving the efficiency of the food industry.
