2. Preface With the global green transformation underway, the electrification of various industrial
processes is emerging as a worldwide trend, extending beyond Japan. This lecture will focus on
the processing of raw materials and by-products in mining processes, which traditionally rely on
fossil fuels as their primary energy source, as well as technologies for utilizing biomass as acarbon-neutral material, aiming for societal implementation. We will invite European
researchers as lecturers to share insights on microwave heating application technology. The
lecture will be conducted entirely online. Given the rare opportunity to hear from these lecturers,
we encourage your participation. Whether you are a member or not, we eagerly await youractive involvement.

13:00～13:45 “JEMEA Regular General Meeting”(Only JEMEA member can connect)【Chair 1: Associate Prof. Shutaro Tsubaki (kyushu University) 】
13:55-14:00 Opening
14:00～15:00 “ Can Microwave Heating Technology Contribute to Coal Alternatives and Powdered
Raw Material Utilization for Next-Generation Ironmaking? ”
Lecturer1：Prof. Ko-ichiro Ohno (Kyushu University)
Abstract: The challenges of transitioning from coal usage and developing technologies for the
direct utilization of powdered raw materials are central to the Green Transformation ofironmaking. This presentation will introduce ongoing research on coal alternatives anddirect utilization of powdered ores, while also discussing the advantages and challengesof microwave heating.
【Chair 2: Prof. Ko-ichiro Ohno (kyushu University) 】
15:00～16:00“ Microwaves as a potential energy source for the co-recycling of electric arc furnace
dust with halogenated plastics ”
Lecturer2：Dr. Sanad Altarawneh (University of Nottingham)Japan Society of Electromagnetic Wave Energy Applications (JEMEA)

Abstract：The accumulation of metallurgical wastes such as Electric arc furnace dust(EAFD) is considered a direct threat to the environment. Current research is split intohydrometallurgical and pyrometallurgical routes to mitigate the environmental
footprint of EAFD. Both approaches pivot around extracting valuable metals namely
zinc and lead leaving behind iron rich residue. The latter has been realised at anindustrial scale, however, with large quantities of harmful emissions to theenvironment along with extensive energy usage. Can the utilisation of microwave
energy provide the solution to these challenges leading to less overall energy
consumption and a reduced harmful emissions?

16:00～16:10

Break【Chair 3: Associate Prof. Shutaro Tsubaki (kyushu University) 】
16:10～17:10 “Biomass-associated reactions with SAIREM microwave equipment: pyrolysis andextraction. Identification of MW effect”
Lecturer3 : Dr. Alisa Doroshenko (SAIREM)
Abstract： Sustainable thermochemical technology for biomass valorisation should becontrollableand selective to maximize the value of biomass resources. Microwave
heating is an alternative to the traditional conventional processes. However, it possesses
improved control and higher selectivity due to a dipolar polarisation heating
mechanism.
Here we report a unique microwave system (MicroChem) with a possibility for an
optimisation of the applied electric field, which substantially increases the number ofsamples suitable for homogeneous microwave heating. The integrated solid-state
microwave generator has superior advantages over the magnetron-based technology
such as operating from 1 W to the maximal power with 1 W step accuracy and choiceof the suitable frequency from 2400 MHz to 2500 MHz. The power balance is providedby SAIREM equipment due to real-time monitoring and control of the forwarded,reflected and transmitted power. A combination of precise power control and power
balance opens an opportunity to determine thermodynamic and the kinetic constants ofthe process, monitoring the phase-transition reactions in real-time.

【Chair 4: Prof. Ko-ichiro Ohno (kyushu University) 】
17:10～18:10 “Microwaves energy as new technology for processing steelmaking sidestreams –Advantages and challenges“
Lecturer4：Dr. Mamdouh Omran (The University of Oulu)
Abstract： Steel industries generate large streams of by-products wastes annually. These wastes are
considered to be hazardous material in many European countries due to their highcontents of leachable heavy metals. The environmental regulations force the metalindustry to take major steps towards efficient recycling of by-products wastes andprohibiting the wastes landfilling. The current recycling techniques still facing
economic, environmental and technical problems due to high energy requirements andhigh pollution. Recently, microwave energy has been proposed as a new promising
method to efficiency recycling steelmaking by products and overcome theJapan Society of Electromagnetic Wave Energy Applications (JEMEA)

disadvantages of traditional recycling methods. In this lecture, a summary of the work
related to microwave processing steelmaking sidestreams, and the main challenges need
to be resolved in microwave technology to move forward and upscaling this techniquefrom the small laboratory scale to the full production scale.
