Workshop on thermochemical technologies for feedstock recycling of waste
IEA Bioenergy Task 36 – Integrating energy recovery into solid waste management systems – will host a technology oriented workshop on so called advanced thermal treatment processes. Drivers and barriers for alternative thermal treatment of waste is one of the key task activities.
Thermochemical conversion technologies can provide a significant contribution to Circular Economy. Although transformation of today’s mainly linear economy towards CE is one of the major sustainability approaches, we have seen little long-term implementation of waste gasification, waste pyrolysis, or similar processes for feedstock recycling, so far. Being increasingly back in the focus, opportunities to promote technology implementation based on previous and ongoing activities and lessons learned speed up.
Bulk waste, typically being collected heterogeneously, can be thermally recycled in waste incinerators. Material recycling that has been implemented for some waste fractions requires extensive pretreatment and is very costly.
Feedstock recycling by thermochemical conversion in contrary deals with bulky waste, mixtures of organic and inorganic content, and degraded end-of-life products in such a way that the overall recycling rate is maximized. These technologies are scalable, can handle difficult feedstocks and can produce specified clean intermediates such as synthesis gas or synthetic crude that can be upgraded to chemicals or fuels in existing petrochemical value chains The purpose of this workshop is to put a technology oriented view on thermochemical conversion of waste as enabler of the future carbon cycle, the de-fossilization of industry and the recycling of mineral construction materials.
It will proceed in the frame of the IEA bioenergy task 36 “waste-to-energy” meeting at KIT, Karlsruhe, Germany on December 5, 2017.
During the workshop, an overview and several presentations on specific technologies will be followed by a discussion on common R&D needs.”
