Many fabrics are considered to be biodegradable, but just because something is biodegradable does not mean that it is sustainable.
Bioplastics, such as polylactic acid, polyhydroxyalkanoates, and starch-based plastics, are derived from renewable materials like cornstarch and sugarcane and are biodegradable. They are essential for addressing the growing issue of traditional plastic pollution and find applications in medical devices, ...
Mainly prized for its ornamental properties, jacquard is also a relatively durable and heavyweight fabric, and it’s possible to accentuate these attributes by weaving jacquard using wool or other durable materials. Uncommonly used in casual garments due to its complexity and relatively high cost, te...

PLA is a new type of biodegradable material, made from starch raw materials proposed by renewable plant resources (such as corn). Starch raw materials are saccharified to obtain glucose, which is then fermented by glucose and certain strains to produce high-purity lactic acid, and then a certa...
More specifically, polypeptides such as collagen and silk are biocompatible materials that are used in pioneering research because they are inexpensive and readily available materials. The gelatin polymer is commonly used in wound dressings where it acts as an adhesive. In addition, biopolymer stent is...
So, what should be deemed “biodegradable”? If we take heed of some of these semi-formal explanations, we can begin to decipher what should be classed as “biodegradable”. Basically, the use of the word should ideally be restricted to products and materials that break down into smaller par...
