The Plastic Processing Sector
The industry’s main products are divided between ﬂexible and rigid structures.
Conventional plastic materials are of fossil origin, petrochemical base that presents high strength and durability. From the extraction of oil, naphtha is obtained, which is the most relevant fraction for the petrochemical sector. Naphtha is a raw material for the production of ethylene, propene, butadiene, benzene, toluene and xylene, inputs for the manufacture of the main types of polymers used in the manufacturing industry.
Bioplastics are plastic materials whose origin of raw materials is renewable, ie they come from maize, sugar cane, beet and these materials may or may not be biodegradable. Example is polyethylene obtained from ethanol via sugarcane which is a bioplastic but is not biodegradable. Biodegradable plastics are those that at the end of their life cycle are physically or chemically modified by the action of microorganisms under certain conditions of heat, humidity, light, oxygen and adequate organic nutrients.
