Abstract:Energy efficiency in companies is addressed by established tools or procedures, such as energy audits or the implementation of an energy management system in accordance with the Energy Efficiency Directive. Both options indistinctly provide sufficient information for companies to identify opportunities for improvement and savings in their energy costs. However, the influence of cultural and behavioral aspects on employees and the organizational and structural configuration of companies impacts the effectivenes… Show more

“…The E2DRIVER project is an improvement of the INDUCE program [1], which in its conclusions determined that the methodology can be a very useful tool to promote energy efficiency in a company of any industrial or service activity in Europe, due to its flexibility and adaptation to any environment. In addition, it improves the results of the actions carried out [2]. In this case, the methodology developed is implemented in SMEs in the automotive sector.…”
Energy efficiency requirements in Europe are set by the Energy Efficiency Directive, considering energy audits as a systematic procedure to determine the savings in energy costs. These kinds of tools provide useful information for companies to identify opportunities for the improvement of their energy performance. However, the regulation is only applied for non-SMEs in Europe, which make up only 0.2% of the total number of European companies. Compared in terms of the value added or the number of employees, these companies are still at a lower percentage than small and medium enterprises. The wide versatility of small companies, however, makes it difficult to determine a regulation that promotes the objective of the Directive in a uniform way. For this reason, one aspect that is being worked on with small companies is raising awareness and training in energy aspects, encouraging them to carry out activities to improve their energy performance based on their own initiative. In this regard, within the framework of an H2020 research project based on the automotive sector, the E2DRIVER project, a collaborative–cooperative training methodology has been designed to motivate and empower the key actors within a company. This paper describes the methodology and its implementation in different companies in European countries, providing some representative results.
“…However, the main challenges facing the industry are high energy and water consumption, large waste generation as well as emissions of CO2 to the atmosphere (Scheller et al, 2008). The food and beverage industry is the biggest consumer of energy and causes 67% of the greenhouse gas emissions (Millán et al, 2020). It has been reported that, the major consumers of electricity in breweries are refrigeration (44%), packaging (20%), and compressed air (10%) (Scheller et al, 2008).…”
The brewery industry has a significant contribution to the national income. However, it is also associated with energy-intensive processes and pollution. In this work, the energy efficiency assessment of the largest brewery in Tanzania i.e., Tanzania Breweries Limited has been conducted. Energy consumption analysis was conducted according to IEEE SA 739-1995. Important parameters used to assess brewery energy efficiency were boiler efficiency and losses, equipment energy productivity as well as load factor. It was found that the main energy consumers are packaging (54.63%), brewing (29.30%) and utilities (15.17%). More importantly, it was found that about 68% of the brewery energy demand is thermal energy which is supplied by the boiler whose efficiency (62%) is significantly lower than the expected value of 94-95%. Load factor analysis showed that the equipment of both brewing and packaging line 4 are significantly oversized. Furthermore, energy productivity of 45.5 kWh/L of beer is significantly higher than the industry minimum of 23.6 kWh/L.
