What is the MBT Process and how is the Solid Refuse Fuel made?
- Reception – Municipal Solid Waste (MSW) placed by resident’s curbside as it is today, will be brought to the proposed facility by a local hauler. The MSW will be deposited into an indoor aerated reception pit. Air is continuously drawn into the building to avoid odor buildup inside the Facility. There is no combustion or incineration in this process.
MSW processed at the Facility is anticipated to include all of the waste currently allowable by local waste haulers including but not limited to, kitchen organic waste, mixed unsorted paper, plastics, etc. Excluded waste includes all wastes that are currently prohibited by the local waste hauler such as hazardous waste, used oil, source separated recyclables, white goods and construction debris.
- Pre-screening – MSW will go through an initial screening process using a large rotary drum that will tear open the trash bags and combine the bagged waste with other non-bagged MSW. Large pieces of waste such as plastic, paper and cardboard are separated from the MSW and set aside for use during the refining stage. The remaining waste, including organic waste is referred to as “underscreen” material, is smaller in size and goes directly to a holding area. An air circulation system will be used to ensure rapid composting of the organic fraction of the waste. The air circulation system blows warm air through the under-screen waste in order to quickly start up the aerobic composting fermentation process.
- Biological treatment (oxidation/composting) – The underscreen material is moved from the holding area and placed on a pre-fabricated concrete floor that contains slots through which processed air is moved. The processed air is comprised of a controlled combination of fresh air and re-circulated warm air, which ensures a consistent breakdown of the waste. This reduces the amount of water in the material leading to a dry paper-like product. There is no combustion or incineration in this process.
- Refining – After the biological treatment stage, the now dried under-screen material will be re-introduced to the previously removed over-screen material in the refinement area of the facility. Using rotary screens, air separators and magnetic/infrared technology, the material is further separated to remove any metals and PVC plastics that may remain. Metals will be sent to the County Recycling Center on Grapevine Road. The PVC plastics will be sent to the local landfill. The product is then shredded into smaller pieces resulting in a product that can be used as an alternate fuel replacing traditional fuels, such as coal and petroleum coke.
How will emissions/odors from the facility be controlled?
Who will build the facility?
- A bonded Engineering, Procurement and Commissioning (EPC) Contractor
- A bonded General Contractor
- A design-build and construction management firm specializing in pre-engineered metal building design and construction
- Local contractors will be selected as sub-contractors for various elements of the construction of the proposed facility
- It is estimated that approximately 50-100 individuals could be involved in the construction project

Where will the MSW come from?
- The MSW would come from surrounding counties needed to operate the facility
- Household waste and C&D waste can be accepted.
- Select commercial waste may be accepted
