Title: Latest Trends in Polystyrene Recycling - March 15, 1999

In 1998, the Polystyrene Recycling Association released data on the recycling status of expanded polystyrene (EPS). EPS is widely used as packaging material, and its recycling is crucial from an environmental protection perspective. The recycling rate in 1998 reached 51.5%, an increase of 1 percentage point from the previous year. Of this recycling, material recycling accounted for 31.2%, where EPS is processed into ingots and pellets and reused as plastic products. Another major recycling method, thermal recycling (energy recovery), accounted for 20.3%, where EPS is used for power generation and heat sources.

The increase in the recycling rate can be attributed to the expansion of EPS collection points called "Epsie Plazas," established independently by the Polystyrene Recycling Association. In 1998 alone, the number of Epsie Plazas increased by nine, leading to a rise in recycling volumes due to the heightened awareness and proactive efforts of companies in recycling and technology development.

The domestic shipment volume of EPS in 1998 reached 200,000 tons for domestic raw materials and 100,000 tons for imported raw materials. The amount of recycled EPS has increased proportionately, and reuse both domestically and internationally is advancing. Additionally, with advancements in recycling technology, the efficiency of material recycling has improved, and the quality of recycled products has also been enhanced. For example, improvements in the quality of ingots and pellets used as recycled plastic from EPS have been reported, contributing to the increase in the recycling rate.

Regarding thermal recycling, technological improvements in incineration facilities have led to increased energy recovery efficiency. These technological advancements have made it possible to recover energy through the thermal decomposition of EPS, contributing to the reduction of environmental impact. Furthermore, technologies to suppress the emission of harmful substances during incineration have been developed, minimizing environmental impact.

The Polystyrene Recycling Association plans to continue developing and promoting recycling technology, aiming to further increase the EPS recycling rate. They are also focusing on expanding the market for recycled products, collaborating with companies and local governments to build a recycling system. These efforts are expected to accelerate progress toward realizing a circular society.
