<p>High-performance low-pollution process for the production of cellulose paste from annual plants, in which the process comprises the stages of: - subjecting the annual plant material to dry cleaning, - separating the cortical part from the inner woody part, - subjecting the raw material obtained from either the cortical part or the inner woody part separately to a washing operation, - subjecting the washed product to a mechanical pressing process. The process makes it possible to produce low-pollution wastes which can be purified at low cost, and is suitable for the production of cellulose pastes even in small installations.</p> |
