Agricultural and Industrial Systems for Materials Handling, Air Quality and Biomass Energy

  • Biofilters for VOC's, vapors, mists, and odors.

  • Fuel, seed and feed bins, conveyors and controls

  • Advanced materials handling systems

    for currency disposal, conveyors, dust collectors, compactors.

  • Hay Dryers and Compactors for Export Markets

    T.R. Miles has developed commercial systems for drying and compacting hay and straw for export since 1975. The dryer and compactor designs have been in commercial operation since the 1990s. Drying systems include custom designs and testing use of moving floor, belt, rotary and suspension dryers for hay, herbs, switch grass, corn stalks, and bagasse. Large handling, processing and feeding systems have been designed for power boilers and biofuel production

  • Straw Utilization

    Innovative process and uses for straw utilization since the 1970s including straw fiber through thermomechanical pulping for hydromulch and wet process boards. He conducted pilot and small industrial scale field testing of system for handling and preparing straw for use as fuels, feeds, fibers, feedstocks for chemicals to test options for the utilization of more than 1 million tons of grass seed straw produced in the Willamette Valley of Oregon.

  • Feed Systems for Biomass Energy

    The special expertise of the firm is the development of energy conversion and materials handling systems for wood, straws and food processing residues. Project areas include harvesting and processing of Field Crops and Residues; Harvesting and processing of Forest Residues and Urban Wood; Boilers, Combustion, Carbonization and Gasification; Organic Recycling, Composting and Manure management.

The Bioenergy Lists are informal technical mailing lists for organized around the following bioenergy topics:

Created by Center for Renewable Energy Studies (CREST) and later hosted by the the Renewable Energy Policy Project (REPP), the Bioenergy email lists have hosted a world wide technical conversation that has nurtured effective, on the ground applications of renewable energy since 1994.
