IEA IETS Task 21 Decarbonizing industrial systems in a circular economy framework

Energy and CO2 savings through circular economy, especially directly through circularity in the area of carbon, and resource and energy efficiency through industrial symbiosis are two main approaches to decarbonizing industry. At the level of the IEA TCP "Industrial Energy Technologies and Systems", Task 21 was first established as part of a definition phase and then managed in a first period at the request of the Climate and Energy Fund, operationally carried out by the Energy Institute at the JKU Linz. Central Austrian tasks in the second period, which includes two subtasks (#2 Circular Carbon and #3 Industrial Symbiosis), are the management of the entire Task 21, the management of the subtask Circular Carbon and the content-related contributions to both subtasks; in addition, the requirements for dissemination and communication will be fulfiled.

The subtasks deal with (2A) how CCU can be integrated in LCA and energy system modelling, (2B) how carbon capture technologies can be established effectively and efficiently in different industries, (3A) industrial symbiosis is to be delimited scientifically and theoretically, (3B) which best practice examples exist for industrial symbiosis, (3C) which business models for industrial symbiosis exist or are proposed, and (2C/3D) which interactions exist with the topics of other IEA TCPs or IETS tasks.

The international work is accompanied by a comprehensive national communication and dissemination strategy, which ensures the involvement of stakeholders and the bidirectional transfer of knowledge.
The goals and expected results are the international broad discussion of the handling of captured carbon and industrial symbiosis in theory/modeling, but also, derived from this in practical, political and legal matters.
