It is necessary to work in a joint and articulated way, generating collaboration and innovation to propose new ways of manufacturing, use, reuse and recycling of plastics. It is urgent to address and prevent environmental problems, but at the same time the Pact invites us to take advantage of the enormous opportunity for value creation that is generated.

Chile is the third country to implement the Plastics Pact, along with the United Kingdom and France, and is the first country in Latin America and the first developing country to join this Global Network. This initiative expresses the determination to collaboratively lead the change in production models and, with it, their impact on the environment.

The Chilean Plastics Pact will work in line with the vision of the Global Commitment launched by the Ellen MacArthur Foundation. Four commitments have been defined for 2025, the progress of which will be communicated annually.

When and how was plastic invented?

The first plastic was parkesin, invented by the English chemist Alexander Parkes in 1862. It was essentially nitrocellulose softened with vegetable oils and camphor. The American John W. Hyatt discovered the fundamental role of camphor in plasticization and named the substance celluloid.

What is plastic and what is its origin?

Plastics are synthetic chemical substances, called polymers, with a macromolecular structure that can be molded by heat or pressure and whose main component is carbon. These polymers are large clusters of monomers bonded together by a chemical process called polymerization.

Who invented plastic?

Leo Baekeland, the Belgian millionaire who invented plastic while practicing his favorite hobby. Caption, It was created 110 years ago but today we continue to use plastic more and more.

Plastic has been incorporated into all societies, whether industrialized or agricultural, in remote places or in large cities. It has been used for clothing, for packaging or for play. It has been a phenomenon on such a scale that never in the history of mankind has there been a discovery of such rapid development and in such unimaginable proportions.

Alexander Parkes was born in Birmingham in 1813. He had no specific training in physics or chemistry but was occupied for a time in the processing of natural rubber, at a time when great strides were being made in this field with the discovery of vulcanization and the first processing machines.

Studying the cellulose nitrate obtained in 1845 in Basel by C.F. Shoenbein, Parkes obtained a new material that could be “used in its solid, plastic or fluid state, which appeared from time to time rigid like ivory, opaque, flexible, water resistant, colorable and it was possible to work it with a tool like metals, to stamp it by compression, to laminate it”.

When did the use of plastic begin?

In the 1930s, English chemists discovered a thermoplastic called polyethylene (PE). … In the 1930s, the first man-made fiber, nylon, was created. Its discoverer was the chemist Walace Carothers.

What is plastic explained for children?

Plastics are those materials that, composed of resins, proteins and other substances, are easy to mold and can change their shape permanently after a certain compression and temperature. … The condition of plastic is known as plasticity.

What type of material is plastic?

Plastics are materials obtained artificially through a major chemical transformation of substances of organic origin, i.e. they are synthetic materials that do not occur naturally.

Who created plastic

Plastics are synthetic materials made of polymers, large molecules consisting of a very long chain of repeated units, which, hence the name, can be shaped by heating. Each plastic has a certain temperature at which it ceases to be hard and brittle and becomes soft and malleable. A distinction must be made between thermoplastics and thermo rigid materials. The former remain malleable until they melt and retain the shape they have been given; if they are reheated, they can be reshaped by tensile forces. This happens because of the nature of the forces that hold their polymer chains together in a solid, with sufficient heat they can slide over each other. The shape of thermosetting materials, on the other hand, becomes unalterable above a certain temperature, usually high; the reason for this is the creation of cross-links, bridges of atoms that bind the polymer chains together and prevent the material from softening again when reheated. Cross-linked materials do not melt or dissolve, although they can absorb solvent; when they have absorbed too much, they become gels.

What is the plastic process?

By compression: The plastic material is pressed into the desired shape. By transfer: The molten plastic is pressed into a mold by means of a piston. Calendering: Forms plastic sheets. It is used for materials that withstand high temperatures and require special production processes.

When was half of the plastic in the world today manufactured?

Plastic use and production have accelerated to breakneck speed, with more than half of all plastic being manufactured after 2005.

How does the emergence of plastic affect today and in the future?

In addition to the fact that prices can be lower than other natural products and the improvement of technology, the use of plastic has increased and with it its impact. The marine environment is the most affected and its degradation is more harmful than on land. It also receives the largest percentage of plastic waste.

Origin of animal, vegetable or mineral plastic

Plastic is a material made up of organic or synthetic compounds that have the property of being malleable and can therefore be molded into solid objects of various shapes. This property gives plastics a wide variety of applications.[1] 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.[8] The plastics industry began with the development of plastics.

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.[9] Baekeland’s first synthetic polymer is called Bakelite.
