據安迅思休斯敦4月5日消息，美國Origin公司與AECI SANS Technical Fibres宣布擴大合作關系來開發Origin公司將生物質轉化為對二甲苯(PX)的工藝。

該合作伙伴關系包括一項購買碳排放為負值的聚對苯二甲酸乙二醇酯(PET)的協議，PET將用于廣泛的終端產品，包括服裝、內衣、鞋類和汽車縫紉線應用。

SANS是Origin的戰略投資者AECI的全資子公司。該公司生產用于服裝和汽車的線。

兩家公司還將合作開發和商業化基于Origin生產可再生PX工藝的新產品。

Origin公司的工藝可以將木質生物質轉化為可用于制造可再生PX的中間體。這個過程的碳排放是負值。

其他公司也曾嘗試生產可再生PX，但都以失敗告終。可再生PX不僅有助于抵消溫室氣體排放，而且提供了一種成本上具有競爭力的替代傳統的PX來生產PET。

然后，PX被用來生產精對苯二甲酸(PTA)，PTA與乙二醇(MEG)結合生成PET。

如果成功，Origin相信這種碳排放為負值的材料將幫助革新廣泛的終端產品，包括服裝、紡織品、塑料、包裝、汽車零部件、輪胎、地毯和玩具。

該公司估計，其技術的市場價值約為1萬億美元。

US Origin and SANS expand partnership to develop renewable PX from biomass

US Origin and AECI SANS Technical Fibres announced an expansion of a partnership to develop Origin’s process to convert biomass into paraxylene (PX).

The partnership includes an agreement to buy carbon-negative polyethylene terephthalate (PET) to be used in a wide array of end products, including clothing, intimate apparel, footwear, and automotive sewing thread applications.

SANS is a wholly owned subsidiary of AECI, a strategic investor in Origin. The company makes thread for apparel and automotive applications.

The two companies will also work together to develop and commercialise new products based on Origin’s process to make renewable PX.

Origin’s process takes woody biomass and converts it into an intermediate that can be used to make renewable PX. The process is carbon negative.

Other companies have attempted and failed to make renewable PX. The feedstock would not only help offset greenhouse gas emissions, but offer a cost-competitive alternative to traditional PX to make PET.

PX is then used to make purified terephthalic acid (PTA), which is combined to monoethylene glycol (MEG) to make PET.

If successful, Origin believes its carbon-negative materials will help revolutionise a wide range of end products, including clothing, textiles, plastics, packaging, car parts, tyres, carpeting and toys.

The company estimates that the market for their technology could be worth about $1tr.
