A kraft pulp mill mixes chemicals,wood chips, and steam in a pressure-cooking vessel, which just happens to be called a "digester". Then the pulp
gets washed...in a "washer", of course....and then it gets pressed to remove the water and gets dried into shape.
But you don't have to put up millions of dollars to make paper. Use goats or sheep as "digesters", while you wash and dry.
Can't do much about the smell. Our noses are sensitive enough to smell a pulp mill from miles away--hydrogen sulphide only needs
a few parts per trillion to be detected as a "rotten egg" smell.
Goat and sheep poo in a large concentration isn't much better.
