Kirin Unveils New and Faster Recycling Method for Plastic Bottles

Directions: Read the following article aloud.


Kirin announced a new technology for simpler and speedier recycling of plastic bottles that will enable the use of more recycled material in manufacturing.

Kirin Central Research Institute, a subsidiary of Kirin Holdings, announced a new technology in recycling PET bottles on December 15. The new development reduces the time it takes to break down plastic material by about 90%. The technology is based on chemical recycling, where raw materials are broken down to the molecular level to recover chemical components. Kirin aims to implement the technology by 2030.

Conventional chemical recycling methods require high temperatures of several hundred degrees Celsius and high pressure to break down PET (polyethylene terephthalate), a raw material used in plastic bottles and synthetic fibers. Processing can take several hours.

With the new technology, a mixture of PET, an alkaline component, and alcohol at specific ratios enables the plastic to degrade at a low temperature in the 35 to 55 degrees Celsius range, and in a short time of around 15 minutes.

The research institute also reported a new development in the purification process after dissolution based on joint research with Waseda University. This new technology allows for a significant reduction in the use of the chemical substances that were previously essential.

Kirin has set a goal to use recycled resin for 50% of the domestic PET resin by the year 2027. Along with the introduction of this new technology, the company plans to address challenges in scaling up and continuous operation to commercialize the new processes. The company plans to seek new partners for this purpose. A spokesperson from the Kirin Central Research Institute explained, "We aim to create an environmentally-conscious society where resources circulate."

ペットボトルの分解時間を9割削減でキリンが新技術 令和12年の実用化目指す

キリン中央研究所は15日、ペットボトルなどのリサイクルにかかる分解時間を約9割削減する新技術を開発したと発表した。

キリンホールディングス(HD)傘下のキリン中央研究所は15日、ペットボトルなどのリサイクルにかかる分解時間を約9割削減する新技術を開発したと発表した。原料を分子レベルにまで分解してから化学原料を回収する「ケミカルリサイクル」技術によるもので、令和12(2030)年までの実用化を目指している。

従来、ペットボトルや合成繊維などの原料になるPET(ポリエチレンテレフタラート)を分解するには数百度という高い温度と高圧力が必要で、処理に数時間かかっていた。新しい技術ではPETとアルカリ成分、アルコールを一定割合で混ぜることにより35~55度の低温で、しかも15分程度の短時間で分解できる。

また、分解後の精製工程でも、これまで必要だった化学薬品を大幅に削減できる新技術を早稲田大との共同研究で開発したという。

キリンは9年までに国内のPET樹脂使用量の50%をリサイクル樹脂にする目標を掲げる。今回の新技術では大規模化や連続運転などの課題解消と実用化に向け、新たなパートナーを探す方針。キリン中央研の担当者は「環境に配慮しながら資源が循環し続ける社会を目指す」と話している。
