Abstract
A pulping method using KOH-K2SO3-AQ system as cooking liquor on wheat straw was studied in this paper. Digestion quantities on pulp yield and hardness during cooking was discussed and determined. It looks promising to use effluents of cooking into fertilizer because it contains rich nutrition such as potassium and lignin. A new pattern of ecological cycling may be set up between paper industry and farming.
