Abstract

Today, the meat processing industry plays an important role in boosting the economy of the region of Alentejo, Portugal, which possesses a strong economic linkage to rural traditional activities. However, several problems have been detected relating to an efficient use of the energy in their productive processes, leading to excessive and unnecessary consumptions, increasing bills and therefore costs of final products, reducing company’s competitiveness and causing increased emissions of greenhouse gases to the atmosphere.
The aim of this study is to characterize energy consumption of the meat processing industry in Alentejo, to understand where excesses are being committed and at the same time to identify opportunities for improvement of energy performance in the productive process. For this purpose data were collected through a field survey within a sample of companies and the respective findings were statistically analysed. Subsequently a study of the technical–economic impact of a set of efficiency measures was evaluated to reduce energy consumption and cost.
Results obtained showed that it is in the refrigeration systems and heat boilers that it is possible to achieve the largest reductions in energy consumptions and energy over costs, which may go up to 7 % (savings on consumption) and 19 % (savings on cost) through the implementation of efficiency measures with a payback period of less than 11 years.
