Plastic injection problems and contaminants on the living environment and its prevention (NH Engineering Group)

The material we deal with on a daily basis and is abundant around us, and if not used properly, is dangerous to the environment, it is plastic

One way to produce plastic appliances and products is plastic injection molding

In the following article, we will examine the harmful effects of plastic on the environment and ways to prevent it and the proper use of this material.

Definition of plastic pollution

Due to its suitable and useful properties, plastic has been and is a very valuable material for human beings.

In the definition of plastic pollution, it can be said that plastic products are collected in the environment, which is harmful to the environment and the residents and causes them problems.

?Types of environmental hazards of plastics

Toxic effects of plastic are the most important hazards that plastic can have on the environment, very few plastics are recycled; Most of them remain in the environment and will take about 1,000 years to decompose. During this time, toxins enter the soil and water.

These plastic parts are available all over the world and can cause any negative impact on the environment.

Investigation of plastic pollution of waters

How do plastic toxins get into the water and contaminate it? One of the most important reasons is clothing. The materials of fine acrylic, nylon, polyester, etc. fibers enter the sewage every time we wash our clothes. These materials are either processed in the waste processing system or directly into the environment.

According to research, every time a washing machine is turned on, more than 700,000 microplastic plastic fibers enter the environment, and if this trend continues, almost all sea fish will be destroyed by 2050.


When all kinds of plastic decompose in the environment

Normally, plastic parts remain in the landfill for up to 1000 years until they are finally decomposed.

Plastic bags take 10 to 1,000 years to decompose, and plastic bottles take 460 years to decompose.

Decomposable plastic

HDPE is a plastic that can be recycled, used for milk bottles, detergents and oils, toys and some types of plastic bags, and the process of recycling HDPE plastics is very simple and inexpensive.

Plastic production rate

About 350 million tons of plastic are produced worldwide each year, 52 percent of which is disposable; The use of these plastics lasts for a few minutes, but the effect they have on the environment is several years.

Iran’s production is estimated at 360,000 tons.

The newest and best methods of plastic recycling

About 10 percent of the plastic products that have been produced so far have been recycled.

Researchers are now using two methods to recycle plastic:

In the first method, plastics such as water bottles: washed and crushed or grated, melted and re-produced.

The second method, which is used for dirty and contaminated plastics, is spitting or pyrolysis; the method of work is to break the plastic with high heat to be used as oil and for energy.

Recycling mark on plastics

The triangle recycling symbol is marked with the numbers 1 to 7 inside it.

The meanings of the numbers are as follows:

1 Inside the triangle: Polyethylene terephthalate plastic material is PET or PETE. It is usually used on bottles of non-alcoholic beverages and water, salad dressings, vegetable oil dishes and mouthwash bottles.

2 Inside the triangle: Polyethylene compressed plastic (HDPE). Bottles of milk, shampoo, motor oil bottles, shopping and trash bags, bags inside serial boxes, and bottles of household cleaners and detergents.

In the following articles, we will examine other numbers.
