Question

Write a report on the topic 'Plastic'

Answer 1

Answer:

Hii friend

Explanation:

Plastic bag pollution has become a hot topic. We've all heard about how plastic bags pollute oceans, rivers, and eventually our food supply. Yes, even the food we eat. There are reported facts about how bad that plastic bags are for the environment and the ocean. Is there scientific evidence to prove these facts? There are reports that say the facts are wrong. The reports, counter-reports and arguments filter down to what I call "The Plastic Bag Wars".

There seems to be a plastic bag frenzy. Countries, states, cities and counties are writing legislation and passing ordinances to eliminate plastic bags or decrease their use.

Plastic Bag Ban Report

The Plastic Bag Ban Report (PBBR) brings all the screaming frenzy together in one place. PBBR reports the latest on:

Plastic Bag Bans

Proposed Plastic Bag Bans

Fee Only Bans (charging a fee for using plastic bags)

Legislation and Ordinances

Battles: Arguments For and Against plastic bag bans

PBBR also brings you other information related to plastic bags, such as:

Ocean Debris

Reducing Plastic Bags

Recycling Plastic Bags

ReUsing Plastic Bags

Alternatives to Plastic Bags

Stay informed of what's happening in the Plastic Bag Wars.

I hope it's helpful for you

Answer 2

Answer:

Plastics are a wide range of synthetic or semi-synthetic organic compounds that are malleable and so can be molded into solid objects.

Plasticity is the general property of all materials which can deform irreversibly without breaking but, in the class of moldable polymers, this occurs to such a degree that their actual name derives from this specific ability.

Plastics are typically organic polymers of high molecular mass and often contain other substances. They are usually synthetic, most commonly derived from petrochemicals, however, an array of variants are made from renewable materials such as polylactic acid from corn or cellulosics from cotton linters.

In developed economies, about a third of plastic is used in packaging and roughly the same in buildings in applications such as piping, plumbing or vinyl siding. Other uses include automobiles (up to 20% plastic), furniture, and toys. In the developing world, the applications of plastic may differ—42% of India's consumption is used in packaging. Worldwide, about 50 kg of plastic is produced annually per person, with production doubling every ten years.

Plastics have many uses in the medical field as well, with the introduction of polymer implants and other medical devices derived at least partially from plastic. The field of plastic surgery is not named for use of plastic materials, but rather the meaning of the word plasticity, with regard to the reshaping of flesh.

The world's first fully synthetic plastic was bakelite, invented in New York in 1907, by Leo Baekeland who coined the term 'plastics'. Many chemists have contributed to the materials science of plastics, including Nobel laureate Hermann Staudinger who has been called "the father of polymer chemistry" and Herman Mark, known as "the father of polymer physics".

The success and dominance of plastics starting in the early 20th century led to environmental concerns regarding its slow decomposition rate after being discarded as trash due to its composition of large molecules. Toward the end of the century, one approach to this problem was met with wide efforts toward recycling.

Plastics are made from natural materials such as cellulose, coal, natural gas, salt and crude oil through a polymerisation or polycondensation process. Plastics are derived from natural, organic materials such as cellulose, coal, natural gas, salt and, of course, crude oil.
