At first, significantly higher-yielding cellulose sources can come from conventional breeding, experts say.

When rayon was first made, the cellulose sources were wood pulp and short cotton fibers that were not long enough to go into making yarn.

Dedicated energy crops, such as switchgrass, are also promising cellulose sources that can be sustainably produced in many regions.

Schweizer's reagent finds use in production of cellulose products such as rayon and cellophane, because wood-pulp, cotton fiber, and other natural cellulose sources are soluble in the solution.
