The plastic industry includes the global production, compounding, conversion and sale of plastic products. Although the Middle East and Russia produce most of the required petrochemical raw materials, the production of plastic is concentrated in the global East and West. The plastic industry comprises a huge number of companies and can be ...
Alginates are the natural product of brown algae and have been used extensively in wound dressing, drug delivery and tissue engineering, as well as food applications. [ 9 ] [ 10 ] [ 11 ] Sodium alginate is an unbranched copolymer of 1,4-linked-β-d-mannuronate (M) and α-l-guluronate (G) sugars.
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.
Consumer Reports and other advocates are calling on the U.S. Food and Drug Administration to reassess whether these plastic chemicals should be permitted in materials that come into contact with food.
Demand for plastic resins in Europe during 2017 as a percentage of total plastic demand. [1] A comparison of standard plastics, engineering plastics, and high-performance plastics Commodity plastics or commodity polymers are plastics produced in high volumes for applications such as packaging, food containers, and household products, including ...
The plastics industry manufactures polymer materials—commonly called plastics—and offers services in plastics important to a range of industries, including packaging, building and construction, electronics, aerospace, manufacturing and transportation.
The term raw material denotes materials in unprocessed or minimally processed states such as raw latex, crude oil, cotton, coal, raw biomass, iron ore, plastic, air, logs, and water. [1] The term secondary raw material denotes waste material which has been recycled and injected back into use as productive material. [2]
The plastic kits and covers are mostly made of synthetic polymers like polythene, and tires are manufactured from polybutadienes. [1] However, due to the environmental issues created by these synthetic polymers which are mostly non-biodegradable and often synthesized from petroleum, alternatives like bioplastics are also being considered.
