    The compatibility of economic and ecological sustainability is increasingly determining the strategies of manufacturing companies. The focus of ecological sustainability is primarily on energy and material efficiency in the company's own production. However, many possibilities that could already be used in the company's own production to re-duce energy consumption and increase material efficiency remain unused. In the me-dium to long term, for an economy in a sustainable society, moreover, cross-company activities will increasingly have to be initiated and become effective. This requires close, product-specific cooperation from all participants along the respective value chains as well as the development and implementation of new sustainability approaches. There-fore, this paper presents current best practices for increasing energy and material effi-ciency in manufacturing. With a view to the potentials of tomorrow as well as the future challenges, promising possibilities and examples for realising the urgently needed cir-cular economy will continue to be highlighted, taking into account different R-cycles based on the digital twin of product and manufacturing.

    When manufacturing products, it becomes increasingly important to consider ecological factors in addition to conventional key performance indicators such as manufacturing costs, time or quality. The greatest leverage for creating the most sustainable form of product manufacture is in the early stages of technology planning, because emissions can be avoided in the long term through the selection of sustainable technologies. However, there are methods that allow ecological factors to be taken into account during technology planning to supplement the usual key performance indicators, but the level of detail and the applicability are not yet sufficient. In order to support decision makers in the planning and evaluation of technology chains, this paper develops a methodology that supports technology chain selection. For this purpose, an economic-ecological key performance indicator was developed which combines manufacturing costs, material flow costs and environmental impacts determined through life cycle assessment to enable a holistic view.
