What are 5 common plastics used in homes?

The 7 types of plastics

These changes undergone by the material have a direct impact on its recyclability. Thus, the elements of its composition will determine how possible it is to recover material from these plastics to reuse it and establish a less polluting consumption chain.

It is used in beverage bottles such as soft drinks or water, as well as in other light packaging such as food packages, cream jars and other pharmaceutical uses. Its second life is usually new bottles, textiles for clothing, carpets, models, tarpaulins and nautical sails or threads and ropes. Its recyclability level is 1 and the toxic substances it contains are antimony, formaldehyde, acetaldehyde and phthalate. It accounts for 11% of plastic waste on the planet.

It is used in many non-transparent containers such as milk bottles, detergents, food packages and motor oil. Its use after recycling is usually for new packaging, boxes, flower pots, garbage containers, toys, pipes, pieces of urban and garden furniture or new detergent bottles. Although its recyclability level is 1, it is a more resistant material than PET and contains antimony as a toxic substance. It accounts for 14% of plastic waste in the environment.

When we say “plastic” we are not referring to a specific materialBefore we start with the types of plastic, we must understand that when we say “plastic” we are not referring to a specific material. The nature of plastics is very diverse. A plastic is a material that is malleable and flexible at certain temperatures. Plastics are usually characterized by the fact that they are made up of polymers. This term refers to huge chains of molecules linked together to form a stable structure. In the polymerization process, the individual molecules are joined together one after the other to form a chain or mesh by changing some of their physical conditions. Thus, the plastic becomes… plastic. But, as we said, these molecules are not always the same. There are all kinds of substances that differ in their properties, their formation process, etc. For all these reasons, plastics have become indispensable substances in our industrial processes, construction, chemistry and much more.

What are the most commonly used plastics in your home?

Polypropylene (PP)Polypropylene is a thermoplastic derived from propylene gas. Often, this plastic is processed into fibers.polypropylene is the lowest density mass-produced plastic and floats on water. Its stability and resistance to chemicals is similar to that of low-density polyethylene, however, it can be used at higher temperatures. Since polypropylene is odorless and does not irritate the skin, it is widely used in the food and pharmaceutical industries.Uses:Food packaging, household appliances, automobile parts, construction, garden furniture, artificial turf, suitcase casings, medical devices, plastic bags, etc.

Polyvinyl chloride (PVC)Polyvinyl chloride is produced from chloroethene gas, known as vinyl chloride. This rather rigid plastic can be made elastic by adding plasticizers. Phthalates used as plasticizers in PVC can make up to 70 % of the material.PVC is a highly fire-resistant insulating plastic, making it an ideal material in the construction industry, particularly for pipes and window profiles. On the other hand, PVC is far from harmless: not only does it consist of carcinogenic raw materials and unhealthy phthalates, but it also releases toxic dioxins during combustion.Uses:Floor coverings, drainage pipes, window profiles, gaskets, vinyl discs, floats, etc.


– Polyethylene (HDPE) (high density, low density, linear low density, etc.): It is used to create various products such as: bags, cling wrap, flexible bottles, toys, tubes, juice and milk containers, etc.

– Polyvinyl Chloride (PVC): It is mainly used in specific fields such as construction and medicine. In the manufacture of flexible plastics for medical devices, and to cover floors, ceilings, or to insulate electrical cables.

– Polyethylene Terephthalate (PET): This variant is mainly used for bottled liquids such as soft drinks, milk, juices, chemicals, etc. It is one of the most popular plastics at international level.
