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

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.

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.

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, optimizing the enzyme mixture, controlling process microbiology and developing the overall process concept. We will demonstrate also how bioethanol can be produced from construction wood and packaging waste, also as a continuous process.

 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.

 Key learning objectives:

  • Hear where we stand on the way to commercializing waste textile fibres
  • Discover the modern processing technologies that enable efficient utilization of lignocellulosic waste streams
  • Learn how to create added-value products from various waste streams
  • Find out the elements that form the competitive edge of the renewed raw material business
