Speech title "Pretreatment based on ball-milling and thermal hydrolysis for anaerobic digestion of slaughter byproducts"
Abstract-Biogas production from unconventional biomass, such as livestock residues or slaughter byproducts has been a challenge due to their long biodegradation periods. In this study, we aimed to produce biogas by anaerobically digesting animal residues, e.g., internal organs, skins, etc. collected from a local slaughterhouse after it was pretreated with a ball-mill process and a subsequent thermal hydrolysis. Food waste was used as a base feedstock to which slaughter byproducts were added. A series of batch experiments were performed with the slaughter-byproduct-containing food-waste samples to evaluate their biomethane potentials. Three treatments were prepared; (1) the unconventional biomass without any pretreatment, (2) a mixture of food waste and the livestock residues without pretreatment, and (3) a mixture of food waste and the livestock residues pretreated by the ball-mill and thermal hydrolysis processes. When food waste was alone anaerobically digested, 654 mL of CH4 could be produced over the 25-day of digestion period. However, the anaerobic digestion of the unconventional biomass without pretreatment could produce only 100-mL CH4, which is slightly higher than the amount of CH4 produced from the control without any organic substrate. From this result, it was confirmed that the biomass from a slaughterhouse was not easily biodegradable. When the un-pretreated slaughter byproducts and food waste were mixed at an 2:8 ratio and digested in a batch reactor, 571 mL of CH4 could be produced over the batch digestion period. Normalizing this result based on the mass of food waste added to the reactor revealed the unconventional biomass had not been digested. Finally, the mixture of food waste and the livestock residues pretreated via ball-milling and thermal hydrolysis could produce 658 mL of CH4. Calculating the amount of the unconventional biomass added to the mixture, it was found that the pretreated slaughter byproducts could produce CH4 of about 74 mL g-1VS L-1, which is 2.1 times higher than the amount of CH4 produced by the un-pretreated slaughter byproducts (i.e., 35 mL g-1VS L-1). From the result of the current study, it was concluded that even unreadily biodegradable biomass could, if properly pretreated, be a promising alternative bioenergy source.

Speech title "Transforming Water Governance in Japan: Leveraging Green Infrastructure Solutions"
Abstract-Abstract—Japan has improved its approach to managing water resources and developing infrastructure in response to the need to address diversifying water resource demands, socio-economic changes, climate change, and environmental concerns. This presentation discusses the evolution of policies, strategies, and technologies that have shaped Japan's water governance framework. It also introduces the green infrastructure that has emerged and developed as a result of growing concern for environmental issues. Historically, Japanese water management strategies have focused on large-scale infrastructure projects, such as dams and levees, to manage water resources and reduce flood risks. However, growing concerns about the environmental and social impacts of these traditional approaches have led to a shift toward a more sustainable and integrated water management model. Green infrastructure combines engineered solutions with approaches that harness natural functions to achieve multiple objectives, such as improving water quality, reducing flood risk, enhancing climate resilience, and promoting biodiversity. This presentation provides insights into the evolution of Japan's water governance and the development of green infrastructure, offering valuable lessons and inspiration for other regions seeking to achieve sustainable and resilient water management systems.

Speech title "A study on adaptation measures to climate crisis for water supply system of Jeju Special Self-Governing Province"
Abstract-Risk assessment on Jeju Special Self-Governing Province(JSSGP)'s water supply facilities and establishment of adaptation measures for climate crisis factors were implemented. JSSGP's vulnerability to the climate crisis was high in the order of drought, heat wave, heavy rain and strong wind. As a drought adaptation measure, a water saving policy is considered to be a priority in terms of demand management and a policy to improve the revenue water ratio management. As for the heat wave adaptation measure, the introduction of an advanced water treatment process was suggested in response to the increase of algae cell number which resulting in taste and odor problem. As for heavy rain adaptation measures, the installation and operation of automatic coagulant injection devices for water purification plants that take turbid surface water were proposed. As a measure to adapt to strong winds, stabilization of power supply such as installation of dual power line was proposed in preparation for power outages. It is expected that water facilities will be able to supply high-quality tap water to customers in extreme climate conditions without interruption through risk assessment for climate crisis factors and active implementation of adaptation measures.

Speech title "Expanding sustainable energy by way of hydrogen energy systems"
Abstract-While the world’s energy sources
become less based on fossil fuels like coal, oil and natural gas,
two energy forms, hydrogen and electricity, are expected to be the
two dominant energy carriers for the provision of end-use energy
services, in what is often referred to as a hydrogen economy.
In particular, as relatively easily accessible fossil fuel supplies
become scarcer or more expensive to harvest and as environmental
concerns, especially climate change and the global warming that
leads to it, expand and become more concerning, hydrogen is likely
to become an increasingly important chemical energy carrier.
The growth for sustainable energy is enhanced through the use of
hydrogen energy systems in which hydrogen is an energy carrier.
The technologies needed for hydrogen energy systems are undergoing
much research and development. For instance, there are many
processes and technologies for producing hydrogen, for the
transport, distribution and storage of hydrogen, and for utilizing
hydrogen as an energy carrier, especially in transportation.
In this presentation, the role of hydrogen as an energy carrier and
hydrogen energy systems, and their economics, are described and
reviewed.
