Abstract In Japan, full‐scale waste plastic recycling business started around 1970. Since then, in parallel with the efforts to develop new uses of recycled products, remarkable progress has also been made in recycling/molding technologies. The most popular recycling/molding technologies applicable to thermoplastics are of melt‐and‐mold type. This presentation discusses the technologies in their present situations, economics and existing disadvantages. The quality standards are set for some recycled products, the relations among recycling technologies, products' physical properties, and quality standards. Among others, explanations are given of waste‐derived solid fuel manufacturing technologies, incineration technologies paired with thermal energy recovery currently available.
