Biodegradable polymers are mostly plant-base materials, which means they originally come from organic source like soybean or corn. These organic plants have the chance to be sprayed with pesticides which contain chemicals which can contaminate the crops and be transferred into the final finished product.
List of some addition polymers and their uses Polymer Abbreviation Properties Uses Low-density polyethylene: LDPE: Chemically inert, flexible, insulator: Squeeze bottles, toys, flexible pipes, insulation cover (electric wires), six-pack rings, etc. High-density polyethylene: HDPE: Inert, thermally stable, tough and high tensile strength
Starch is a common biodegradable additive, and blends of synthetic plastics with starch are becoming more and more prevalent. Because starch is a polymeric carbohydrate, it can be directly consumed by microorganisms. Starch is a renewable and cheap resource that is available all year round, making it a viable biodegradable additive. [1]
Different types may be suitable for agricultural use. A starch-based (grafing) hydrogel is biodegradable and cheap, and can be modified to adjust its ability to hold water. [3] Cross-linked acrylic acid polymer hydrogels are commercially available; they are effectively insoluble [4] but slowly break down releasing toxic acrylamide. [5]
In theory, laundry detergent sheets take less fuel to ship and can be made from biodegradable materials. However, some brands like Earth Breeze are made in China so the energy savings are ...
