Reusable plastics number
PET is one of the most widely used plastics in consumer products, and is found in most water and pop bottles, and some packaging. It is intended for single-use applications; repeated use increases the risk of leaching and bacterial growth. PET plastic is difficult to decontaminate, and will require cleaning up harmful chemicals. Polyethylene terephthalates can release carcinogenic substances.
HDPE plastic is the rigid plastic used to make milk containers, detergent and oil bottles, toys and some plastic bags. HDPE is the most commonly recycled plastic and is considered one of the safest forms of plastic. It is a relatively simple and cost-effective process to recycle HDPE plastic for secondary use.
HDPE plastic is very durable and will not break down under exposure to sunlight or extremes of heating or freezing. For this reason, HDPE is used to make picnic tables, plastic lumber and waste containers, park benches, truck bed covers and other products that require durability and weather resistance.

These changes in 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 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.
Toxic plastic numbers
But do we know exactly what plastic is and what it is made of? Plastic is composed of resins, proteins and other substances that are easy to mold permanently. They are usually shaped by pressure and heat. They have some properties that make them very suitable for the uses we give them since they are quite resistant to wear and tear, as well as light.
We can find them mainly in water or beverage bottles. Once recycled, they can be made into new bottles, synthetic fibers used for textiles and even cosmetic bottles.
It can be found in many containers such as milk bottles or motor oil. After recycling, it is often used to make new packaging, boxes, toys, detergents, pots and even some furniture.
It is present in credit cards, pipes, cable sheathing, synthetic leather or some door and window frames. After being recycled, it can be used as drainage and irrigation tubing.
Plastic number 7 examples
Plastic is a material made up of organic or synthetic compounds that have the property of being malleable and therefore can be molded into solid objects of various shapes. This property gives plastics a wide variety of applications. Its name derives from plasticity, a property of materials, which refers to the ability to deform without breaking.
In 1839 Goodyear in the United States and Hancock in England developed in parallel the vulcanization of rubber, i.e. the hardening of rubber and its increased resistance to cold. This was the beginning of the commercial success of thermosetting polymers.
The plastics industry begins with the development of the first thermoset plastics by Baekeland in 1909. Baekeland produced the first synthetic polymer and also developed the plastic molding process, which enabled him to produce various articles of commerce. These early plastics were named Bakelite in honor of their discoverer. Bakelite is formed by a condensation reaction of phenol with formaldehyde. Baekeland’s first synthetic polymer is called bakelite.
