The Ames, Iowa, refuse-derived fuel (RDF) plant is consistently processing 150 TPD of commerical residential waste. RDF from the plant is burned at the city's power plant and recovered metals are sold on a regular basis. The processing system is a single process line having a design capacity of 50 TPH. The system uses 2-stage shredding with ferrous metal recovery in between. After secondary shredding, the material is density-separated in a vertical-chute air classifier, which is similar to the Saint Louis unit. About 85% of the waste processed is recovered in the light fraction of the air classifier as RDF. An A1 recovery sybsystem consisting of a trommel screen and eddy-current magnetic separators connected in a series has not functioned successfully. About 7% of the total waste processed is recovered as ferrous metals and sold as scrap. Heat value of the Ames RDF averages 5700 Btu/1b, the moisture content 22%, and the ash content 17%. Project captial cost totalled $6,300,000. Plant operating and maintenance costs averaged $12.50/T of waste processed from June to December 1976. RDF and metals revenues averaged $10.25/T of waste processed. Capital costs of the Ames plant is compared to that produced in the St. Louis plant.
