Description
Greener straw pulping with soda ash help is the advance in a 2026 study by Qixi Xu and co-authors. Normal oxygen-alkali pulping of wheat straw runs hot, chews up cellulose, and lets silicon foul the process. Their low-heat method adds sodium carbonate and recycles the alkali mix.
At set heat and alkali levels, pulp yields rose over the standard method, and the test paper grew stronger on both pull and crush measures in the trials reported here. Far less dissolved silicon stayed in the waste liquor than under the old method, easing a key snag. The authors say the route gives steady, high-grade straw pulp with less waste strain.
