The Iowa Economic Development Authority (IEDA) Board has approved incentives for a $55.5 million expansion by Archer Daniels Midland Company (ADM) that will strengthen the company’s precision fermentation capabilities in Clinton, Iowa.


The project is part of a wider package of assistance approved by the IEDA Board for manufacturing, community and strategic infrastructure projects across the state. Collectively, the two manufacturing projects supported by the board are expected to create 98 jobs and generate $57.2 million in new capital investment.


For ADM, the investment will see an underutilised 463,503-square-foot fermentation facility at its Clinton complex converted into a precision fermentation operation designed to support the production of additional high-value biobased products.


The project includes the installation of new processing equipment for separation, purification, drying and packaging, alongside upgrades to existing fermentation equipment, piping and supporting systems. The improvements are intended to enable large-scale production of proteins and enzymes, highlighting the growing role of precision fermentation in the development of new ingredients for food, feed and industrial applications.


ADM, a major global processor of agricultural commodities and producer of food, feed and industrial products, expects the project to create 53 jobs.


To support the expansion, the IEDA Board awarded ADM $2.23 million in tax credits through the state's Business Incentives for Growth (BIG) programme.


The investment comes as precision fermentation continues to attract attention across the food and beverage industry, with companies exploring its potential to produce proteins, enzymes and other functional ingredients more efficiently and at greater scale.


Beyond ADM's project, the IEDA Board also approved assistance for another manufacturing company, as well as Community Attraction and Tourism grants for projects in Forest City and Larchwood. In addition, three university-led Strategic Infrastructure Program projects received funding aimed at strengthening Iowa's advanced manufacturing, aerospace and defence innovation ecosystem.
