The core of the IETS activities is carried out in so called Tasks (previously called Annexes). Each Task has a defined work program and its own Task Manager (previously called Annex Manager). Interest in involvement and participation in the activtities within the Task should be expressed to the Task Managers directly. Please find contact details in the articles presenting each Task. More information about the formal steps to participate can be found in the About section of the website.

New Tasks can be proposed to the IETS Executive Committee (ExCo). Contact the IETS secretariat or ExCo chair for more detailed instructions.

Decarbonizing industrial systems in a circular economy framework

This Task aims to investigate the topic of circular carbon from an industry perspective, i.e. to describe industrial energy systems in the context of a sustainable, fossil-free economy, striving to meet the targets of both concepts, the circular economy and a sustainable energy system. Read more »

Membrane Processes in Biorefineries

Within the concept of biorefineries membrane processes have been identified as a key separation technology due to their high selectivity and low energy consumption. While the design and operation of membrane processes in other industrial sectors, e.g. the dairy industry, is well established, the design, integration and operation of membrane processes in biorefineries is largely empirical. The fact that process streams in biorefineries contain a large variety of components increases further the complexity. Read more »

Industry-based biorefineries towards sustainability

Annex XI has a multi-disciplinary approach to the concept of biorefineries integrated in industrial complexes, aiming at the optimization of energy efficiency in global terms. The approach is based on industry needs and application, combining the knowledge of industrial technologies with energy efficiency and biomass conversion processes. Different industrial sectors are considered, including the integration of bio with oil refineries, together with CCS options yielding hydrocarbons/hydrogen, looking into technology and systems aspects for a better use of energy.
