Examples of materials posted on the marketplace (and their potential reuses) include common items such as bulk wooden pallets (mulch base) or used bricks (building materials). Other items reflect materials from industrial processes, such spent foundry sand (to be mixed with potting soil), and specialized items such as spent hydro-treating catalyst (metals recovery).
Along with browsing for materials, users of the marketplace can post "wanted" items, thereby seeking items that may serve as substitutes for raw materials or other items they currently purchase. Examples of such requests that have been posted thus far include bulk alumina oxide (for metals harvesting/recovery) and bulk food waste in packaging (to be used for anaerobic digestion/energy recovery).
In the circular economy, products and byproducts recirculate productively through reuse, remanufacturing, recycling and maintenance. Users of the Ohio Materials Marketplace can make or save money by finding a market for their unwanted materials and avoiding landfill tipping fees; buyers save money by having access to sellers' discounted (or free) materials; Ohio's environment benefits by having more material removed from the waste stream, Ohio EPA says.
Ohio is the first state in the U.S. to adopt a circular economy program of this scope and scale. This leadership from the Ohio EPA is paving the way for other states -- through a new public-private partnership between the U.S. Business Council for Sustainable Development and the Environmental Council of the States (ECOS) -- to launch state-level programs modeled on the Ohio Materials Marketplace over the next few years.
