Abstract

Food processing industries are extremely large consumers of thermal energy as well as bio waste generation and there are huge opportunities to improve its utilization. In this study a medium scale spirit plant situated in China was audited. Based on the data obtained, energy and mass balances were performed in order to find the sources of thermal energy, the potential cost effective reduction, recovery and assess potential uses to lower the fossil fuel consumption and CO2 emission. Fermented grains are used for the spirit production and even though they are re utilised during the process at the end are disposed as biological waste consisting mainly of wet distillers grains. The feasibility of using the waste as fuel for direct combustion or co-combustion with coal for the steam generation was studied and evaluated.
