The technologies that should be developed to make small-scale solid waste processing facilities attractive and viable for small municipalities with solid waste between 50 and 250 tons per day are identified. Research and development needs for refuse derived fuel systems, thermal systems, and biological processes are listed. Selected research and development needs discussed for mechanical processing systems are: develop data bank for low-cost, low-energy shredder options; develop performance data for shredders applied after separation; develop data bank for Trommel performance; and identification and evaluation of low-cost materials separation equipment. Selected research and development needs discussed for thermal systems are: emission levels from solid/waste/to/energy systems; determination of the theoretical efficiencies for thermal processing systems; boiler erosion/corrosion evaluation for systems firing refuse derived fuel; optimization of feed and ash handling systems; refractory life and maintenance requirements; development of 5- to 20-TPD systems; and optimization studies of control systems for small modular incinerators. Selected research and development needs discussed for biological processing systems are: optimum design and operation to maximize gas recovery rates and investigate process configuration alternatives for anaerobic digesters.
