Cellulose in a circular economy - When will trash become cash?

Sponsored by: VTT

Focused on:

  • Cellulose
  • Waste Fibres
  • Waste Raw Materials

Date: 1 December


Time: 3PM London/10AM New York

Boost your business with waste streams from textiles, packaging and construction wood

Can we find new affordable fibre raw materials from waste streams? How can technology solve problems of fractionation and refining for fibre upcycling? Where are we on the way to commercializing recycling of textile fibres? This webinar reviews the status of technology and novel solutions for fibre recycling to brand-new consumer products, materials and fuels. All presented technologies have been piloted at ton scale.

Closed-loop textile recycling

Innovations that exploit waste textile fibres will answer to the need created by the new landfill regulations as well as to the need of growing textile fibre markets. We will show how VTT has developed technologies for textile fibre upgrading and is starting industrial-scale production of textile fibres from post-consumer clothes. www.reloopingfashion.org

Optimizing sugar production from waste streams

In certain cases, production of fermentable sugars from lignocellulosic waste streams is feasible. We will show how to optimize sugar production from waste streams by adjusting pretreatments and developing the overall process concept. We will demonstrate also how bioethanol can be produced from wood and packaging waste, also as a continuous process.

Construction waste to materials for new innovative outdoor applications

Construction waste can also be upgraded through defibration to new construction materials (e.g. for insulation) through mechanical treatments. We will demonstrate how established technologies can be applied to different waste raw materials.

Join this webinar to learn how you could speed up your development activities related to waste fibres.
