Review of energy efficiency technologies in the food industry: Trends, barriers, and opportunities

Abstract:

The industry sector has a significant responsibility for the depletion of fossil fuels and emission of carbon dioxide. Thus, several initiatives have been implemented by the industry sector to mitigate those issues. One initiative corresponds to the implementation of energy efficiency strategies. In particular, the food industry is heavily dependent on fossil fuels, and the food demand is expected to grow significantly in the coming years. Therefore, developing energy efficiency strategies for this particular industrial sector is crucial. This paper investigates the different opportunities for energy efficiency in the food industry. It first provides a brief overview of the various food industries and related energy consumption. Then, the different options for energy efficiency in the thermal and electric sector are discussed. New trends and opportunities, arising from industry 4.0 and demand response, are also presented.
