据路透社2023年5月25日报道，美国著名化学制造商陶氏化学公司周四表示，陶氏化学公司日前已与生物转化公司New Energy Blue公司签署了一项长期供应协议，从玉米残渣中提取塑料材料，以期向可再生能源生产迈进。

陶氏化学公司全球可持续发展总监Manav Lahoti表示：“此次合作有助于重新定义我们为化学产品采购原材料的方式，使我们能够将可再生原料纳入其中。”

作为协议的一部分，陶氏化学公司将支持New Energy Blue公司即将在爱荷华州建立的工厂的设计，该工厂预计每年将处理275万吨玉米内芯和玉米叶来生产乙醇，其中将近一半的乙醇将转化为陶氏化学产品的生物基乙烯原料。

乙烯通常由石脑油制成，乙烯是加工成塑料等产品的石化产品的基本原料。

陶氏化学公司表示，该公司的目标是通过使用由农业残留物制成的生物塑料，减少生产所需的化石燃料，并减少随后的温室气体排放。

这项协议还为陶氏化学公司未来4个New Energy Blue公司项目提供了类似的商业供应选择。

今年4月，陶氏化学公司宣布与工业气体制造商林德公司建立合作伙伴关系，为加拿大拟议中的净零碳排放乙烯及其衍生物综合体提供清洁氢气和氮气。

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.
