The invention is aimed at all players whose interest is to manufacture a biodegradable and compostable eco-friendly product which only uses processes, treatments, natural products and virgin biobased materials in order to obtain a product. molded or a product shaped from a lamination of which at least one surface is made hydrophobic by the sulfurization technique. Manufacturing processes allowing the production of a molded product and / or resulting from a molded lamination based on vegetable and animal and / or mineral pulp made hydrophobic by sulfurization or vegetable paraffinization (1) in that process no. 1 breaks down as follows: Wood and / or vegetable and / or mineral pulp absent of chemicals (10) is deposited or injected into a mold (11) to undergo a first forming pressurization to the desired shape, but without the all of its water content is removed, then the molded product with or without the mold depending on the case is soaked in a sulfuric acid bath or accepts spraying on at least one side (12) in order to break the fibers long and the resulting short fibers are partially solubilized and form a cellulose gel, which then remains plated on the molded product and clogs the pores, thus ensuring its impermeability and then the molded product is either directly passed to water and dried or accepts a second molding (12).
