| 1. A method of converting municipal solid waste into a useful compost material, the method comprising the following steps:
providing a stream of solid waste for treatment;
extracting materials from the solid waste;
scanning the remaining solid waste with a Geiger counter to detect the presence or absence of radioactive materials;
removing any detected radioactive materials from the solid waste;
grinding the solid waste into particles of 1 millimeter or less;
transferring the ground solid waste into a drum;
adding manure and sludge to the drum and thereafter sealing the drum;
rotating the drum to mix the ground solid waste, manure and sludge;
sterilizing the contents of the drum by adding steam in an amount sufficient to pressurize and heat the drum to 120° for approximately
37 minutes;
permitting the drum to cool for a period of 10 to 30 minutes and thereafter depressurizing the drum by venting the remaining
steam;
removing the contents of the drum.
