據安迅思新加坡10月11日消息，韓國SK創新公司周二在一份聲明中表示，該公司將在2025年下半年之前投資約1.7萬億韓元(12億美元)在韓國蔚山建設一個塑料化學品回收利用工廠。

該工廠占地21.5萬平方米，預計回收利用能力約為25萬噸/年，將有三個化學品回收利用過程，即高純聚丙烯(PP)的提取、解聚和熱解。

聚乙烯(PE)/PP、聚對苯二甲酸乙二醇酯(PET)和復合材料可以在該工廠回收利用。

該工廠將由SK創新旗下子公司SK Geo centre運營。

《韓國先驅報》援引SK Geo centre一位官員的話報道稱，該工廠將于2023年9月開始建設，建成投產后預計每年可生產約22萬噸“純塑料”。

今年1月，SK Geo centre和美國回收利用服務公司PureCycle同意在蔚山建立一個以分解為基礎的6萬噸/年回收聚丙烯(PP)合資工廠，計劃于2024年底完工。

PureCycle擁有專利技術，可以幫助從PP塑料垃圾中分離污染物、氣味和顏色，并將其轉化為超純回收（UPR）塑料。

蔚山塑料回收利用工廠是SK創新未來5年總投資目標5萬億韓元的一部分，該公司正在加速實現其凈零排放目標。其中3萬億韓元將用于通過生產設施改造和擴能增加環境友好型產品的產量。

公司方面表示：“石油產品作為直接能源資源，沒有替代品，因此計劃在中長期內更換生產設施，并對已生產的石油產品進行循環利用。”

S Korea’s SK Innovation to build W1.7tr Ulsan chemical recycling complex

SK Innovation will invest about Korean won (W) 1.7tr ($1.2bn) to build a plastic chemical recycling complex in Ulsan, South Korea by the second half of 2025, the company said in a statement on Tuesday.

The complex, which is expected to have a recycling capacity of about 250,000 tonnes/year, will be built at a 215,000sqm site and will have three chemical recycling processes, namely, high-purity polypropylene (PP) extraction, depolymerisation and pyrolysis.

Polyethylene (PE)/PP, polyethylene terephthalate (PET) and composite materials can be recycled at the complex, it added.

The complex will be operated by SK Geo Centric, a subsidiary of SK Innovation.

It is expected to yield about 220,000 tonnes/year of “pure plastic”, news daily Korea Herald reported, quoting an official from SK Geo Centric. Construction will begin in September 2023.

In January, SK Geo Centric and US-based recycling service firm PureCycle agreed to build a dissolution-based 60,000 tonne/year joint venture recycled PP plant in Ulsan, slated for completion at the end of 2024.

PureCycle owns proprietary technology that helps separate contaminants, odours, and colours from PP plastic waste to transform it into ultra-pure recycled (UPR) plastic.

The Ulsan plastic recycling complex is part of SK Innovation’s targeted W5tr total investment over the next five years as it accelerates achieving its net-zero emissions goal.W3tr will go into expanding eco-friendly products through facility conversion and expansion.

“As there is no substitute for petroleum products as an immediate energy source, the company plans to change facilities in the mid- to long-term and recycle petrochemical products it has produced,” the company said.
