30 ILCS 500/45-75: Biobased products.

When a State contract is to be awarded to the lowest responsible bidder, an otherwise qualified bidder who will fulfill the contract through the use of biobased products may be given preference over other bidders unable to do so, provided that the cost included in the bid of biobased products is not more than 5% greater than the cost of products that are not biobased.

For the purpose of this Section, a biobased product is defined as in the federal Biobased Products Preferred Procurement Program.

This Section does not apply to contracts for construction projects awarded by the Capital Development Board or the Department of Transportation.
