Production of muesli is an energy intensive process which consumes enormous amount of energy invarious forms. In this study, energy flow accounting tool has been employed which is a valuable tool for mapping and quantifying the energy flows within a specific system such as a nation, city or factory. Thistool aids in highlighting the pathways of energy throughout the system and identifies the sources ofenergy loss. Furthermore, to support identification and assessment of CP measures the energy flowaccounting method was integrated within the CP assessment methodology framework. Energy balance established with the help of energy flow accounting method, also highlights different energy inflows andoutflows in the process such as steam, oil, gas and raw material. The utmost energy consuming subprocesses in muesli production are cleaning, rolling, air blowers, husk removal, extruder and mothermachine. Since Läntmannen Cerealia at Järna generates steam, hot water and district heating from removed husk, along with recovering the steam loss in form of condensate, the overall efficiency of their system is approximately 90%. Moreover, an attempt to establish extensive energy balance at the plant has not been undertaken. This factor serves as the stimulus for the study project as it promises futurework in this domain. This comprehensive report demonstrates a nearly accurate picture of the energybalance of muesli production at Läntmannen Cerealia. The energy losses in different manifestation ofenergy during various sub processes have also been presented in the report. Additionally, suggestions for improvement have been furnished to reduce the energy losses during the process of production. However, feasibility analysis is recommended before the implementations of these measures. Implementation of the aforementioned measures could potentially decrease the energy losses in production of muesli and can boost the environmental performance of the entire process.
