The joint project ‘Energy and Sustainability in the Textile Industry: Energy Efficiency and Renewable Energies in Partnership for Climate Protection’, funded by the Federal Ministry of Education and Research (BMBF) from 2021 to 2025, aims, among other things, to support the Indonesian textile industry on its path to a sustainable future. As part of this project, ifeu is responsible for the ecological assessment of current processes in the Indonesian textile industry and measures for greater sustainability. This includes, among other things, the optimisation of processes, the substitution of technologies and the comparison of textile products. The questions included in the ecological assessment were defined by the project partners.
One of these questions was formulated by SUNfarming GmbH and addresses the electricity supply for Indonesian textile production and the possibility of a shift towards greater sustainability. The background to this is that demand is currently met by a country-specific electricity mix, approximately 80% of which is based on fossil fuels. In future, part of this electricity supply could be covered by renewable energies, including electricity from photovoltaics (PV). The question was therefore raised as to what ecological impact would be associated with covering part of the electricity demand of the Indonesian textile industry with PV electricity.
The aim of this study is to identify the ecological impact of partially covering the electricity demand of the Indonesian textile industry with PV electricity. To this end, two PV concepts, rooftop and ground-mounted PV, will be considered. In addition, life cycle stages that contribute in a particular way to the overall result are to be identified in order to gain initial indications of possible optimisation opportunities. The research interest also lies in deriving the ecological impacts on the basis of a generic system comparison of ‘conventional electricity generation versus electricity generation from photovoltaics’ and not in relation to specific local conditions and/or a project-specific design.
The interest in findings was covered by a rough assessment in which the key factors influencing the overall result could be identified. A so-called overview life cycle assessment is particularly suitable as a methodological framework for this. A number of specifications are necessary to carry this out, the most important of which are listed in detail in the following chapters.
