TMO Renewables Limited has recently signed a 20-year contract with Maryland-based Fiberight LLC. The said contract involves the construction of waste-to-ethanol plants in the United States in which both companies will be integrating their respective proprietary technologies. As the name implies, the plants will focus on converting solid and associated cellulosic wastes to ethanol. If estimations are correct, this will earn TMO and Fiberight around USD 25 million per annum during the term of the contract.
According to contract provisions, TMO is expected to build a total of 15 waste-to-ethanol plant in the next five years. Apart from the annual revenues, the company will also receive an initial, one-off design fee for each of the 15 plants.
TMO will begin construction of the first plant by next year. To date, five sites have already been identified for construction. Fiberight, for its part, has also agreed to commission some of the plants across the country every year.
Each waste-to-ethanol plant will combine the technologies from TMO and Fiberight. Fiberight utilizes fractionation and digestion techniques to sort non-recyclable municipal solid wastes and other associated cellulosic wastes for conversion to clean fibver stream. This clean fiber stream will then be fed directly to TMO’s technology. This process can recover more than 80% of residential waste and convert them to biofuel without any requirement for external water and energy inputs. TMO’s technology, on the other hand, uses a specialty bio-organism known as thermophilic microorganism to convert biomass to ethanol. The combined efforts from TMO and Fiberight is expected to give the waste-to-ethanol plants an edge in terms of ethanol producing technologies since this will allow their process to become more efficient and to produce less water emissions discharge.
TMO and Fiberight are now pilot testing the process in a demonstration facility in Britain. TMO has produced over 90 gallons per ton of ethanol from municipal waste coming from Fiberight. Fiberight receives revenues from 5 million gallons of ethanol produced from the demo plant in addition to tipping fees that they get from using municipal and commercial wastes.
Right now, half of the municipal waste feedstock is consumed for ethanol production while the remaining half is sold as recoverable plastic and metal materials. |
