A plastic magnet is a non-metallic magnet made from an organic polymer. Plastic magnets could be used in computer hardware such as disc drives , as well as in medical devices such as pacemakers and cochlear implants , where the organic material is more likely to be biocompatible than its metallic counterparts.
The mechanical properties of biodegradable polymers can be enhanced with the addition of fillers or other polymers to make a composite, blend, or copolymer. Some fillers are natural fiber reinforcements such as silk nanofibers, bamboo, jute, in addition to nano-clay, and carbon nanotubes as alternatives to name a few.
Bioplastics can be made from proteins from different sources. For example, wheat gluten and casein show promising properties as a raw material for different biodegradable polymers. [41] Additionally, soy protein is being considered as another source of bioplastic. Soy proteins have been used in plastic production for over one hundred years.
Paintballs, also simply called "paint", are spherical gelatin capsules containing primarily polyethylene glycol, other non-toxic and water-soluble substances, and dye. Paintballs are made of materials found in food items, and are edible but taste disagreeable as they tend to dry up the mouth. [ 4 ]
Mixing these together can give a material with inconsistent properties, which can be unappealing to industry. For example, mixing different colored plastics with different plastic colorants together can produce a discolored or brown material and for this reason plastic is usually sorted by both polymer type and color before recycling.

Disposable plastic cups made from biodegradable plastic. Biodegradable plastics are plastics that can be decomposed by the action of living organisms, usually microbes, into water, carbon dioxide, and biomass. [1] Biodegradable plastics are commonly produced with renewable raw materials, micro-organisms, petrochemicals, or combinations of all ...
Toxic flame retardants can get into black plastic kitchenware and other items because the black plastic used to make them sometimes includes recycled electronic products that contain flame retardants.
Polymer degradation is the reduction in the physical properties of a polymer, such as strength, caused by changes in its chemical composition.Polymers and particularly plastics are subject to degradation at all stages of their product life cycle, including during their initial processing, use, disposal into the environment and recycling.
