Maas Companies announced May 7 that it has been appointed to conduct a court-ordered sealed-bid auction for two former Hero BX biodiesel refineries located in Clinton, Iowa, and South Roxana, Illinois.
This auction follows a federal court order placing the assets into receivership following liquidity issues.

The featured properties for auction are:
Clinton, Iowa facility: Located at 5640 44th Ave South, this site features a 10-million-gallon-per-year renewable fuel plant on approximately 13.33 acres within the Lincolnway Industrial Rail & Air Park. The facility offers strategic logistical advantages, including direct Union Pacific rail access and proximity to major Midwest markets.
South Roxana, Illinois facility: Located at 7350 State Route 111, this now dismantled asset, comprises a former 12-million-gallon-per-year plant situated on 5.59 acres. Positioned in a high-density industrial corridor near the Phillips 66 Wood River Refinery, it provides robust infrastructure for fuel wholesaling and regional distribution.
The sale will be conducted via a sealed-bid auction.
The sealed-bid deadline is June 18 at 4:00 p.m. Central time.
On-site inspections are available in Clinton, Iowa, May 20 from 9:00 a.m. to 3:00 p.m. and June 10 from 9:00 a.m. to 3:00 p.m. and South Roxana, Illinois, May 21 from 9:00 a.m. to 3:00 p.m. and June 11 from 9:00 a.m. to 3:00 p.m.
In addition, Matterport 360 virtual tours and drone tours are available to help potential bidders evaluate the layout, utilities and repurposing potential of each site.
A $20,000 deposit in certified funds will be required to be submitted with all sealed-bid offers.
A 10 percent buyers premium will also be added to the winning bid.
“These facilities represent a strategic opportunity for investors to acquire market-ready assets in the nation’s top biofuel-producing regions,” said Tyler Maas, the chief auctionologist with Maas Companies. “With established infrastructure and prime locations, these plants are well-suited for a restart in biodiesel production or a transition to other industrial manufacturing uses.”
