Also, there is a growing demand for high-precision 3D thin glass components. To reach net zero and meet the market demand, efficient manufacturing technologies need to be developed. In addition, the volatile electricity market makes the implementation of energy-efficient technology a necessity to minimize unit costs. Current processes are both ecologically and economically questionable due to long cycle times, high energy consumption, and low tool lifetime. These aspects can be addressed by Life Cycle Assessment (LCA), where cycle times can be reduced substantially thus enabling low cost and low emission production while retaining high forming accuracy. The ecological assessment of two thin glass forming process chains with the help of LCA is performed. The same glass product will be produced by two different process chains. The main goal is to reduce emissions and unit cost while achieving at least comparable, ideally better, shape accuracy. The LCA can serve as an identification of process optimization potentials. Once these are identified, the process can be optimized using multiple strategies. Three main points will be addressed: Simulative, experimental, and machine learning process development and optimization techniques. This requires deep process knowledge and a fundamental understanding of where emissions, costs, and shape deviations occur. First, the objective and scope of the investigation will be defined. Second, a Life Cycle Inventory (LCI) will be made, defining quantitative process values as well as the functional unit. Last, the impact assessment will provide the ecological impact. An exemplary process chain can be found in Figure 1b. Regarding unit cost, an in-house developed calculation tool will be used to assess the unit cost for both process chains which can be used in an either industrial or scientific setting.enThin glass formingLife cycle assessmentSustainable production600 Technik, Medizin, angewandte Wissenschaften::620 Ingenieurwissenschaftenpresentation
