世界の再生ゴム，ゴム粉末，リサイクルゴムの動向

抄録

Many companies produce reclaimed rubber across the world, including Japan, China, India, the EU, and other countries. However, Japanese production has decreased in recent years. Reclaimed rubber is commonly utilized for manufacturing tire compounds, belts, hoses, rubber mats, and general-purpose rubber products. China is the biggest producer, and India is the second. The new manufacturing process uses twin high-speed screw devulcanization technology. Rubber crumb is used for producing artificial grass, modifying asphalt, and other applications. Manufacturers are seeking technology to make finer crumbs. There has been a growing demand for environmentally friendly, sustainable, and recycled rubber materials from used tires in recent years. Rubber crumb pyrolyzed products and recycled carbon black are among the most popular products in this category. Recycled carbon black is produced by more than 30 companies outside Japan. Silicone rubber can also be broken down and returned to intermediate raw materials.
