New post in our Factbook!

Prof. H. Rechberger, together with C. Roithner and O. Cencic, from TU Wien, Institute for Water Quality and Resource Management, has written a paper on the topic of a novel indicator for the recyclability of products. The recyclability of a product depends on three spheres: 1) the product itself with its material composition, 2) the waste management system and 3) the national economy. All three spheres must be considered for a product as a whole in order to be assessed as recyclable.

For the transition to a circular economy, products should be designed in a way that allows extensive material recovery and easy disassembly.

ISIE SEM 2022 – Congratulations!

At the 14th Socio-economic Metabolism (SEM) conference of the International Society of Industrial Ecology (ISIE) on “Transfering socio-economic metabolism in times of multiples crisis” the focus lied on the sustainable handling of plastics and plastic packaging. This year the conference was held at the Vienna University of Economics and Business (WU), bringing together industrial ecologists from all over the world.

We were delighted that CEC4Europe was able to donate a poster prize to the winner, Ms. Han Gao, from China. The objective of her study was on the consumption pattern of iron and steel in order to explore the disparities of recycling pattern of steel scraps in major economics.

Congratulations once again!

Winner Han Gao, „Characteristics of Steel Scrap Recycling under National Steel Consumption Pattern“

We are already looking forward to the next conference.

ISIE SEM Conference 2022

The Vienna University of Economics and Business (WU), together with the University of Natural Resources and Life Sciences, Vienna (BOKU) and TU Wien, organise the 14th ISIE Socio-Economic Metabolism section conference.

The conference will take place at Vienna University of Economics and Business (WU) from 19-21 September 2022.

CEC4Europe is very delighted and honoured to support the conference and we are already very excited about the many topics that will be discussed, such as

  • Methodological and analytical advances in socio-economic metabolism
  • Concepts, data, and modelling of the stock-flow-service nexus
  • Resource, waste and recycling management
  • Circular economy
  • Socio-economic metabolism and the energy, climate, land and water nexus
  • Trade, supply chains, and their embodied environmental impacts

… and many more.

We wish everyone an informative and exciting event!

Encouraged by the EU Commission’s Circular Economy Package (CEP)

CEC4Europe endorses the importance of closing loops and boosting resource efficiency, but at the same time, pleads for a more scientifically and fact based approach: A systematic analysis of our future raw material needs and all relevant secondary raw material sources is needed so we can achieve the common goals of the circular economy – environmental protection, securing of raw materials, economic benefit, and growth – in an effective and efficient manner, based on scientific evidence. Taking far-reaching economic and environmental policy decisions with an insufficient data basis would be speculative and not in line with the CEP objectives. CEC4Europe is an association under Austrian law, based in Vienna, AT, and registered in the EU Transparency register under No 628480917959-24 (24/06/2015).
