background

Circularity Engineering

... designs engineering systems in such a way that they consist of circular, environmentally compatible and resilient products, components and materials.

Circularity engineering is an ab initio concept starting with the materials selection, product design, manufacturing and process selection and not, like the currently practiced circular economy, starting with the waste of linearly planned products and systems.

As a core element of a holistic resource transition, i.e. for material, energy and also human resources, Circularity Engineering is central part of INATECH's research and education agenda.

Focus topics

Circular and system-integrated photovoltaics


Image

Separable micro and power electronics



Image

Value-preserving multi-material structures


Image

Material and structure digitization



Image

Resilient buildings and their engineering design

Renewable building technology



Vision: Rethink engineering quality - Circular, digital and transformative.

Anchoring ecological, social and health aspects in engineering processes: in the medium term, "Circularity Engineering" should become a core element of sustainable engineering science.


To this end, INATECH is developing the scientific basic principles for new engineering methods, processes and tools that can be integrated into all traditional engineering disciplines:

Methods for circular material and process selection.



Guidelines for a "Design for Circularity"



Manufacturing and recovery processes for circular products


Research and application of value-retention processes



Evaluation methods for resilient, circular and sustainable engineering systems

Circular business models incl. logistics concepts, stock management and resource conservation
