據(jù)路透社2023年5月25日報道，美國著名化學(xué)制造商陶氏化學(xué)公司周四表示，陶氏化學(xué)公司日前已與生物轉(zhuǎn)化公司New Energy Blue公司簽署了一項長期供應(yīng)協(xié)議，從玉米殘渣中提取塑料材料，以期向可再生能源生產(chǎn)邁進(jìn)。

陶氏化學(xué)公司全球可持續(xù)發(fā)展總監(jiān)Manav Lahoti表示：“此次合作有助于重新定義我們?yōu)榛瘜W(xué)產(chǎn)品采購原材料的方式，使我們能夠?qū)⒖稍偕霞{入其中。”

作為協(xié)議的一部分，陶氏化學(xué)公司將支持New Energy Blue公司即將在愛荷華州建立的工廠的設(shè)計，該工廠預(yù)計每年將處理275萬噸玉米內(nèi)芯和玉米葉來生產(chǎn)乙醇，其中將近一半的乙醇將轉(zhuǎn)化為陶氏化學(xué)產(chǎn)品的生物基乙烯原料。

乙烯通常由石腦油制成，乙烯是加工成塑料等產(chǎn)品的石化產(chǎn)品的基本原料。

陶氏化學(xué)公司表示，該公司的目標(biāo)是通過使用由農(nóng)業(yè)殘留物制成的生物塑料，減少生產(chǎn)所需的化石燃料，并減少隨后的溫室氣體排放。

這項協(xié)議還為陶氏化學(xué)公司未來4個New Energy Blue公司項目提供了類似的商業(yè)供應(yīng)選擇。

今年4月，陶氏化學(xué)公司宣布與工業(yè)氣體制造商林德公司建立合作伙伴關(guān)系，為加拿大擬議中的凈零碳排放乙烯及其衍生物綜合體提供清潔氫氣和氮氣。

Chemical maker Dow signs supply agreement for bio-plastic materials

U.S. chemical maker Dow Inc said on Thursday it had signed a long-term supply agreement with bio-conversion company New Energy Blue for plastic materials made from corn residue, in a bid to move towards renewable energy sources for production.

"This collaboration can help redefine how we source raw materials for our products, allowing us to expand to include renewable feedstocks," said Dow Global Sustainability Director Manav Lahoti.

As part of the agreement, Dow will support the designing of New Energy's upcoming facility in Iowa, that is expected to process 275 kilotons of corn stalks and leaves per year to produce ethanol. Nearly half of this ethanol will be turned into bio-based ethylene feedstock for Dow products.

Ethylene, which is generally made from naphtha, is a basic feedstock for petrochemicals that are processed into products such as plastics.

Dow aims to reduce its fossil fuel sourcing for production and subsequent greenhouse gas emissions by using bio-plastic made from agricultural residues, the company said.

The agreement also gives Dow similar commercial supply options for the next four future New Energy Blue projects.

In April, Dow announced a partnership with industrial gas maker Linde Plc (LIN.DE) for clean hydrogen and nitrogen supply for a proposed net-zero carbon emissions ethylene and derivatives complex in Canada.
