Abstract
Discrete absorbant particles, useful for example as an animal litter, are produced by joining together layers of formed paper pulp, the layers being compressed together in such a way as to remain together under normal use conditions, prior to immersion in water, but so as to wholly or partially separate upon immersion in water, so that the particles are easily flushed down a toilet after use. The product also has uses other than for animal litter, such as in floor sweeping, as a mulch, packing, or otherwise.
