Sustainability and circularity – the open science seminar on November 19 | Spoman OS

If you were not able to participate in the Open Science Seminar on November 19 or you want to revisit some of the presentations, you can now find them below.

Minna Hakkarainen, Department of Fibre and Polymer Technology, KTH Royal Institute of Technology

Turning plastic waste to functional chemicals and new materials

Taking care of and re-using produced waste, and in particular plastic and polymer waste, is one of the most immediate challenges for our world. Some obstacles for effective and economically feasible large scale plastic waste recycling are the collection and sorting of plastic waste and the need to ensure access to waste material of good and equal quality without presence of harmful additives, contaminants or degradation products. There is also an end to the possibility to mechanically recycle polymers to new products. Here, some alternative end-of-service strategies are presented turning plastic waste to property enhancers and new materials. These strategies are suitable for low quality plastic waste when the initial steps of reuse and mechanical recycling are no longer an option and include transformation of old plastics into functional chemicals, intermediates or carbon products for further use as polymer additives, adsorbents or monomers for new materials production.



Anders Kildegaard Knudsen, The Danish Plastics Federation

Perspectives for Denmark as a role model for Circular Plastic Packaging

Denmark generates annually 216,000 tons of plastic waste from packaging alone. At a global level, 30% of today’s plastic packaging must be fundamentally redesigned if it is to be recyclable. On the other hand, 50 % of today’s plastic packaging would be economically attractive to recycle, if we adjusted the design and collection structure. The launch of the EU’s first plastic strategy in 2018 lays the foundations for unlocking the circular potential of plastic packaging. A potential that Denmark has a unique opportunity to fulfill, while achieving increased sustainable Danish exports The Forum for Circular Plastic Packaging is a role model for how we in Denmark can achieve constructive results when companies, NGOs, politicians and stakeholders get together and engage in fruitful dialogue. Denmark is in a position to be right at the forefront of developing a circular flow for plastic packaging production and consumption. By rethinking the value chain for plastic packaging, we can put ourselves into a driving seat that can lead to innovation, new jobs, increased competitiveness – and better products for consumers and the environment.



Jasper Steinhausen, Ouroboros A/S

Why is a material focus essential for the circular economy

Jasper is a highly experienced practitioner of circular economy and specialized in helping companies find their pathway in the circular economy and get to action. In this talk he will focus how to approach circular economy, why it is coming at us so forceful and paramount role that a material focus has in the circular economy

Jytte Gad Lauridsen, Central Region Denmark

The importance of materials and initiatives at regional level

When we focus on circular economic the content and different type of materials is the key issue. The Central Region Denmark has been focusing on CE for more than 10 years. We have made testlabs, developed system and collected knowledge and learned from our initiatives at hospitals, industry and municipalities. And we have been cross runners and connected stakeholders from public and private bodies. The development of both the way we produce, consume and act are of importance. As well as standards for materials and focus on design. The Danish Regions has a mayor use of plastic at our hospitals. At the hospitals, with the circularity city initiative and other regional testlabs we are focusing on how we can achieve a more circular economy. Mutual approach and collaboration between the public and private sector are among the key issues and in the Central Denmark Region we would like to contribute to turning national and EU plans and goals into actions.


Anders Egede Daugaard, Department of Chemical and Biochemical Engineering, DTU

Polymers or plastics - does it matter for recycling?

When considering the opportunities there are in exploitation of plastics as a resource, it is relevant to consider the material, its original composition as well as its composition after recycling. Plastics generally contain a broad range of additives dependent on the intended application. Both intended and non-intended additives are important aspects that needs to be taken into account before relevant recycling scenarios can be considered. The presentation will give some examples of different types of plastic and how their origin affects recycling. In addition, we will also present some recent results from selective sorting of plastic fractions in an attempt to provide possibilities with respect to recycling of plastics from household waste.





Klaus Rønde, Quality, Safety and Environment, Vestas Wind Systems A/S

Circular Economy as a natural part of the company

Linking “eco-friendly”, “CO2 life cycle reductions”, “resource preservation”, “product life prolongment” etc. to Business models can create sustained prioritization to the Sustainability agenda. Circular economy provides a framework for this linkage by revisiting economic drivers for company growth: from a linear model with “manufacturing of a product; product usage and finally waste” to circular flows where products, components, materials are kept active at highest possible value with increased output and lifetime. In this session some of these circular economy flows seen in wind power plants from Vestas will be explored.

Sr. Technology Director Søren Kristiansen, LEGO System A/S

Circular economy in relation to LEGO Groups sustainability ambitions

Recycling is the fundament for obtaining a circular economy for plastics. Recycling is an opportunity, but also a challenge for the industry. Some challenges are about standardization, legal requirements and waste handling systems. Beside these challenges technical solutions are required in order create recycled materials which makes it possible to close the loop.
