Speech title "Recycled Construction Materials: Current Status and Future Research Directions"
Abstract—Recycled construction materials,
sourced from construction and demolition waste, offer a sustainable
way to reduce the environmental impact of construction projects.
Despite their significant benefits, several challenges hinder the
widespread adoption of these materials. These challenges include
technological and regulatory barriers, concerns about the structural
integrity and durability of recycled materials, market acceptance,
the construction industry's traditional resistance to change,
quality inconsistencies, and the lack of standardized guidelines.
To address these issues, it is essential to have a comprehensive
understanding of the current research on recycled construction
materials. In this invited speech, I will provide an in-depth
analysis of the research landscape related to these materials. I
will explore their utilization, advancements, challenges, and
potential within the construction industry. The discussion will
cover the current status and emerging trends in using recycled
materials across various categories, including concrete, wood,
steel, plastic, asphalt, and more.
My goal is to inspire ongoing research and development by offering
valuable insights that can shape future research directions and
industry practices regarding recycled construction materials. By
doing so, we can effectively tackle global climate change and build
a sustainable society for future generations.

Speech title "Environmental damage, its causes, and our responses: What motivates restoration?"
Abstract—Economic value is a factor in comparing alternatives for the purpose of policymaking. As the economic value of non-market goods is unknown, economic valuation techniques are applied. This study provides an overview of existing studies that examine if the difference in the cause of environmental damages influences economic value. The modern economic theory stipulates that the result is not influenced by the difference in causes (e.g., natural or human) as long as the result is the same, while psychological evidence has provided the opposite results. Recent studies from both economics and psychology have considered differences in alternative causes, and two effects are proclaimed: outrage (Kahneman et al., 1993), which indicates that people find man-made cases more serious than natural cases, and moral responsibility (Walker et al., 1999), which implies the opposite. Subsequent studies have resolved these opposing claims by pointing out whether or not responsible subjects are specified. Relevant studies have accumulated, but further research is needed because many other factors may be related to the results. This study summarizes most of the related literature and suggests remaining issues for the sake of future analyses and real-life applications.
Anatoly Zinchenko is currently an Associate
Professor in the Materials and Energy Design unit at the Graduate
School of Environmental Studies, Nagoya University, Japan. He earned
his master’s degree from M.V. Lomonosov Moscow State University in
2001 and received his Ph.D. from Nagoya University in 2004, focusing
on the physical chemistry and biophysics of DNA. After completing
his Ph.D., he continued his research as a postdoctoral fellow in the
Science Department of Kyoto University, Japan, where he worked on
constructing artificial systems that mimic DNA assembly in nature.
In 2007, Anatoly accepted a Lecturer position at the Graduate School
of Environmental Studies, Nagoya University, where he began
developing materials based on biopolymers such as chitosan and
cellulose for environmental cleaning. He was promoted to Associate
Professor at the same Graduate School in 2011. In 2019, Anatoly
established the Sustainable Materials Laboratory, which focuses on
utilizing waste plastics and biomass for environmental and civil
engineering applications, including wastewater treatment and soil
improvement. Anatoly has authored approximately 100 refereed
publications that have received over 2000 citations.
Speech title "Application of Biomass Polymer and Nanofiber
Networks for Soil Improvement"
Abstract—Biomass-based alternatives to traditional ground improvement materials are increasingly considered in geotechnical applications owing to the renewability and low carbon footprint of biomass. We have elaborated methods of soil improvement with self-organizing biomass-derived polyions, carboxymethyl cellulose (CMC), chitosan (CS), and their nanofibers. CMC and CS interact electrostatically and being mixed with soil, self-assemble into polymer network films and impart superior mechanical properties to the soil composite showing the unconfined compressive strength (UCS) of 500 kPa in a wet state and 2.5 MPa in a dry state. Furthermore, cellulose, CMC, and CS chitosan nanofibers (NFs) were produced by ultra-high-pressure water jet technology and were also studied for the reinforcement of soil materials. Any type of natural NFs provided a moderated reinforcement effect on the order of 120 kPa in a wet, and 1.7 MPa in a dry state, while is inferior to the effect of polymeric networks Various strategies to increase the reinforcement effect of soil materials with NFs by designing two-component networks or introducing a cross-linking agent were tested. Excellent soil reinforcement, suppressed biodegradability, and chemical functionality of biomass-derived IPECs hold promise in utilizing renewable polymers in geotechnical practices of ground improvement addressing the needs of the sustainable use of resources.
