The paper presents the application of MEFA on a solar panels’ assembly facility in the MENA region. The importance of thorough data collection is highlighted as it allows for accurate mapping of how materials and energy are flowing through a system especially in case of manual assembly lines. The challenges in data acquisition are addressed and the improvement scenarios are presented by using simple innovative methods such as QR codes to streamline the data collection process, saving time and reducing errors. Overall, this paper demonstrates how material and energy flow modelling can be used to identify areas for improvement in sustainability practices in small and medium enterprises using simple digital tools.ensustainabilitydigital toolsmaterial and energy flow analysissolar energyMENA region.Text/Conference Paper10.18420/env2023-0181617-5468
