Abstract:Energy saving is essential for the Dutch society. Together with many other organizations and companies, the Asfalt Centrale Twente (ACT) invests in energy efficiency. The ACT participates in the MJAIII (multi-year agreements) and therefore the ACT has to construct an Energy Efficiency Plan (EEP) for the period from 2017 until 2020. In order to meet the national energy agreements, current measures need to be complemented. The purpose of this research is to provide a recommendation, both to meet the MJAIII and to achieve a two percent energy saving by taking realistic, preferably easily feasible, measures. In order to achieve this goal, a literature study is conducted to investigate and list different energy-saving categories. In addition, the main energy-consuming factors for the asphalt plant, are mapped. Subsequently, an investigation of knowledge about current and future possibilities for energy saving is made. This required information is collected by literature research and interviews with different employees of the ACT. The literature shows that there are many opportunities to save energy in the asphalt production process. This can be achieved by increasing the process efficiency, chain efficiency and by exploiting renewable energy. At least one measure is recommended from each category. A lot of background information, from literature, about energy usage is available to review the feasibility of different measures. Further research is conducted into the basic idea behind the EEP. There are already several measures in the current EEP. These measures are reviewed and a lot of these are still applicable. Implementing these measures can result in an energy saving up to 10.3%. By interviewing, it became clear which measures, from the employees’ perspective are applicable to the asphalt plant of the ACT. Subsequently, the feasibility of these measures is investigated. The employees mentioned many aspects of feasibility. The measures are ranked on feasibility with current knowledge, using a SWOT-analysis and Multicriteria-analysis. For the missing aspects of feasibility, recommendations for follow-up research are given. From each energy- saving category, at least one measure with a high feasibility has emerged. For the process efficiency category, a roof on the PR-asphalt storage and the purchase of an energy efficient shovel give the highest feasibility. For the chain efficiency category, reducing transport movements to and from work is the most feasible measure. For the renewable energy category, switching from the shovel to biodiesel shows a high feasibility. Finally, it is recommended to carry out a follow-up research focused on specific measures. Other measures are also feasible, but different implementations of the recommended measures need to be investigated on social, environmental, economic and technical feasibility.
