ABSTRACT:
A method for converting wastes, particularly municipal solid wastes, into usable low cost fuel is provided which yields discrete, substantially self-sustaining fuel pellets which can be easily shipped and stored in bulk and used by utilities or factories as a replacement for coal or other hydrocarbon fuels. The method includes the steps of pulping and fiberizing collected solid wastes followed by air convection drying and pelletizing thereof within relatively narrow temperature and moisture ranges which have been found to be especially conducive to the production of dense, self-sustaining fuel pellets. Treatment in this manner causes the fibrous organic materials such as paper and cloth in the collected wastes to serve as a type of adhesive binder for holding the pelletized product together and minimizing undesirable high volume, low density fines in the product. In the preferred process, the waste materials are treated continuously and a fraction of the resultant fuel is returned to the process for use in powering the process dryer.
