Current Situation

MDA is operating six ash disposal sites. At these sites infested and non-infested ash are processed to eliminate potential breeding and feeding material for the emerald ash borer. Ash that does not reach a value-added market will be sent to a landfill.

There are several existing markets for material harvested during the eradication process. The major markets for this material in the Detroit area are industrial biomass fuel and landfill cover. Smaller markets exist for commercial landscape mulch, wood pulp chips and solid wood products. These solid wood products can be items such as lumber or railroad ties. More information about these markets is needed.

The State Forester's office has information regarding the location of biomass fuel users, firewood processors, tree care firms and sawmills. MDA has information regarding the location of mulch manufacturers. Landfill locations are also widely known. Additional information about other potential users of this processed material is needed.

New markets may also be available. Chips can be used as a bulking agent for sewage sludge composting, or as feedstock for creation of pyrolysis oils. Pyrolysis oils can be used as heating oil, a carrier for creosote treating, or as a feedstock for the production of various wood chemicals. All of these uses need to be demonstrated in this area.
