Abstract
A process for manufacturing paper from seaweed, including the steps of washing algal material with water, draining the water from the algal material, treating the algal material with an antifermentative to prevent putrefaction, grinding the algal material to a particle size not more than 500 .mu.m, refining the algal material in a paper refiner, mixing the algal material with cellulose fiber to form a homogenous mixture, placing the homogenous mixture in a papermaking machine to make paper. Also, the present invention relates to paper from the above-described process.
