Stainless steel is a group of iron-based alloys containing at least 10.5% chromium, with added elements like nickel and molybdenum to enhance corrosion resistance, heat resistance, and fabricating properties. The American Iron and Steel Institute (AISI) recognizes over 60 grades of stainless steel. Chromium forms a protective oxide layer on the surface, preventing rust by blocking oxygen from reaching the iron base.
“ Society is increasingly concerned about the health of the natural environment and the impact of materials on ecosystems. This awareness has led to the concept of “greening,” where the environmental performance of materials influences selection decisions.
The production process begins with selecting raw materials, which typically consist of 75-85% recycled stainless steel scrap and alloying elements like chromium, nickel, and molybdenum. This mixture is melted in an electric furnace and transferred to an Argon Oxygen Decarburization (AOD) vessel to reduce carbon content. Gaseous emissions are collected, and dust is recycled to recover metallic compounds. The molten stainless steel is then cast into slabs or ingots, which are further processed into various products through rolling, forging, or drawing.
Criteria for Evaluating the "Greenness" of Stainless Steel
A variety of criteria can assess the environmental performance of stainless steel, including:

Japan, one of the most earthquake-prone countries in the world, is leading the way in developing innovative earthquake-proof housing solutions. A standout among these is the levitating house by Air Danshin Systems Inc., a revolutionary technology designed to protect lives by lifting homes off the ground during seismic activity. The concept is simple but brilliant: if buildings kill people during earthquakes, why not temporarily lift them away from danger?

On March 28, 2025, a powerful earthquake struck Myanmar, causing extensive damage across the country and leaving over 140 people dead. The full extent of destruction was initially unclear, particularly in Myanmar, where a civil war has further complicated rescue and recovery efforts. Neighboring Thailand also felt the impact, with at least six fatalities in Bangkok following the collapse of a high-rise under construction. While this tragedy unfolded, it raises a crucial question: how do some countries successfully build earthquake-resistant structures? One of the best examples is Taiwan.

Throughout the history of hydraulic construction, the Chinese have relied on folk wisdom to protect bridge foundations and piers from water erosion and the impact of currents. One of the most unique and effective methods is the use of oysters—marine organisms with the ability to adhere firmly to hard surfaces, forming a natural protective layer for structures. Based on real-world observations, this method has gradually been researched and applied in modern construction, becoming a sustainable building solution.
