Each of these materials requires different amounts of energy to be produced and recovered. Through recycling, the energy cost of using these materials can be reduced. spte tinplate material and aluminum require less energy than plastic and require less energy for recycling. Compared with plastic, recycling tray tinplate and aluminum can save nearly 8,200 kWh of energy.
This is very important, because the energy used for the production, recycling and use of these materials mainly comes from non-renewable fossil fuel resources, which generate waste that is harmful to the environment. More than 80% of all energy produced in the world comes from fossil fuels. The main forms of fossil fuels are coal, oil and natural gas. These are mined, refined and processed through processes that are very energy consuming and harmful to the environment. They come from under the earth's crust, which requires them to use oil wells and mining for mining, both of which have high environmental costs. After extracting and refining them, they are distributed all over the world and converted into energy.
One way to reduce the impact of climate change is to reduce the use of fossil fuel energy. The use of recyclable metals (such as aluminum or tray tinplate) is a good way to reduce energy consumption in packaging production. Compared with plastic, every kilogram of spte tinplate material or aluminum recovered can save 8,000 kilowatt-hours of electricity, which is equivalent to saving 2,300 kilograms of carbon dioxide. This reduction in carbon dioxide is considerable. If metal packaging is used instead of plastic packaging, it will help reduce the negative environmental impact of climate change.
