Due to the decline of the world's forest resources, non-wood fiber sources are becoming increasingly important as raw materials in fiber-based industries, One source of such non-wood fiber is S. alterniflora (Common Cordgrass) and related species, which are large-sized grasses, about 1-1.5 m tall, with leaves 20-60 cm in length). These grasses have invaded many coastal areas in China and can result in huge economic losses. Studies have shown that the fiber composition of S. alterniflora is: cellulose 35.9%, hemicellulose 34.2%, lignin 15.9%, ash 2.98%. The length of S. alterniflora fibers, which are shorter and narrower than bamboo fibers, makes it difficult to utilize S. alterniflora in chemical pulps. However, thermomechanical pulping of S. alterniflora stems can be used to prepare pulps which can then be suitably mixed with chemical pulps and used to manufacture a variety of molded pulp products The raw material for the pulp molding products is used S. alterniflora pulp mixing with other chemical pulp like bamboo pulp, off-cuts from the paper making factory, printing factory, corrugated factory and other paper product factories. The pulp molding products can be collected and reused again, which could control the rapid spread invasive species of S. alterniflora effectively. Even if it is abandoned in nature, it will be biodegraded into fertilizer within a few months.
