We use plastics in every day life. We are also all familiar with plastic recycling. But what happens with the plastic once you throw it in the recycling bin? And what happens to plastics that slip through our recycling stream and end up in the ocean? This symposium sheds light on a broad spectrum of plastic recyling, focussing on the science and engineering involved.

The symposium will take place in Eindhoven, but a teams link will be send to the participants who want to attend online.

Guest speakers:

Dr. Yali Tang

Assistant professor at Eindhoven University of Technology

Dr. Yali Tang at Eindhoven University of Technology is leading a project to clean microplastics from water using acoustic technology. Microplastics are tiny, mostly unseen plastics between 5mm down to 1 micrometer in size. They are the result of break-down of larger plastics as well as microbeads that are added to cleaning and beauty products. They are notoriously hard to seperate/remove from water. Under the effect of an external acoustic field, the microplastics will be manipulated to stick together (agglomerate). These larger agglomerates can then be captured in traditional fashion. The project covers both experiments and simulations.

Dr. Sina Tajfirooz

Winner of the KIVI Hoogendoorn Award. Working formally at Eindhoven University of Technology, currently at Nuclear Research & consultancy Group

Dr Sina Tajfirooz did his PhD research on the numerical modelling of plastics in a magnetic fluid. Using this technique (magnetic density separation), it is possible to seperate various plastics based on density differences. Sina developed a model to predict the motion of these particles in such systems.

Silvia Zanoni

Research Chemist at Ioniqa Technologies B.V.

Silvia Zanoni is a research chemist at Ioniqa technologies B.V., a spin-off company from Eindhoven University of Technology, specialized in PET plastic recycling. Ioniqa’s process consists in transforming all kind of (coloured) PET feedstocks back into their building blocks – the monomers – via a catalytic depolymerization and separation process. These monomers can then be re-polymerized to obtain PET plastic of a virgin-like quality. Ioniqa’s technology contributes to a close-loop circular economy, where plastics can be infinitely recycled back into their original state, removing the need to use crude oil as a source for such materials.
