ABSTRACT:
A water absorbing particulate polymer material wherein the polymer material when in dry powder form has a particle size of about 50 .mu.m to about 500 .mu.m and wherein the particles consist of internally bonded finer particles which finer particles have a size below 50 .mu.m. The process of using the water absorbing polymer, material to convert a wet sticky mass of inorganic particulate such as coal fines into a crumbly or flowable solid. A process using a water absorbing particulate polymer material to convert a wet sticky mass of organic particulate material into a crumbly or flowable solid wherein the organic matter can be, for example, food waste or sewage.
