The present invention relates to a blend of reinforcement fibers for use in a variety of applications. In particular, the blend of reinforcement fibers can be used in cementitious compositions, such as Portland cement concrete and asphalt cement concrete compositions to reduce or preclude voids and/or cracks formed in the cement concrete upon placement. The blend of reinforcement fibers includes a plurality of first fibers and a plurality of different second fibers. The first and second fibers can be different based on coarseness/fineness, melting temperature, denier and specific chemical or material composition. In certain embodiments, one of the plurality of first fibers and the plurality of different second fibers has a melting temperature that is lower than the temperature of an asphalt cement concrete composition such that the plurality of first or different second fibers serves as a carrier/buffer to improve distribution and dispersion of the fibers in the Portland or asphalt cement concrete composition.

An assembly and method for processing human waste includes providing a supporting base having an opening within which a waste reservoir is affixed. The assembly may be installed on or below a rim of a toilet bowl. Solidification and pathogen killing materials are provided. The materials are deposited in the reservoir either prior to or upon accumulation of waste in the reservoir. The reservoir with the solidified waste is then sealed and transported to a collection facility.
