Comparison of carbon emissions of plastic products with other sources

In today's world, people are paying more and more attention to the environment, especially carbon emissions. Covering carbon emissions is related to climate change and has a great impact on everything on earth. In the meantime, the carbon emissions of plastic products are compared with other sources, which is a topic that cannot be ignored.

Watching the production of plastic products requires a lot of energy. From the collection of raw materials to the molding, every step involves energy use, and the consumption of energy is more than the emission of greenhouse gases such as carbon dioxide. For example, when oil is used as raw material to make plastics, when oil is extracted, mechanical operation and energy consumption have carbon emissions; subsequent refining, polymerization and other processes require a large amount of thermal energy and electricity, and carbon emissions also increase.

As for other sources of carbon emissions, one is the burning of fossil fuels. Coal, oil and natural gas are the bulk of today's energy sources and are used in power generation, transportation, industrial production and many other places. Burning these fossil fuels, the carbon element quickly and oxygenates, generating carbon dioxide and emitting it into the atmosphere. Taking coal-fired power generation in power plants as an example, a large amount of coal is burned, and a huge amount of carbon dioxide rises into the air with smoke, and the amount of carbon emissions is quite considerable.

Second, in industrial manufacturing, metal smelting is also a heavy source of carbon emissions. For example, iron and steel smelting starts with iron ore and goes through multiple processes to form steel. During the high temperature reaction, coke and other fuels are required. In this process, the combustion of coke and chemical reactions all cause carbon emissions.

Compared with plastic products, the carbon emissions from the combustion of fossil fuels are wider and larger. Power plants, vehicles, factories, etc. around the world burn a lot of fossil fuels every day, and their carbon emissions far exceed that of the production of plastic products. However, the problem of plastic products is that they are widely used and difficult to degrade. Plastic products are discarded after use and survive in the environment for a long time. Although their carbon emissions during production may not be as large as those of fossil fuels, their long existence and the difficulty of post-disposal make them have a profound impact on the environment.

Although metal smelting has a lot of carbon emissions, its products can be recycled and reused to reduce its environmental burden to a certain extent. Plastic product recycling encounters many obstacles, and the collection rate is low. Most of them are landfills and incineration sites. Landfills occupy land and leachate or sewage soil water sources; incineration generates new carbon emissions and harmful substances, exacerbating environmental problems.

Compared with other sources, plastic products have their own characteristics. In order to reduce carbon emissions and protect the earth's environment, we should control the production and recycling of plastic products; in fossil fuels, we should accelerate the transformation and use clean energy; in industrial manufacturing, we need to innovate technology and reduce carbon emissions. Multi-party implementation is expected to slow down climate change and ensure the safety of the earth.
