The manufacturing industry has difficulty achieving the goal of reducing emissions

According to a new report by researchers at the Massachusetts Institute of Technology (MIT, USA), the manufacturing sector will not be able to achieve the goal of reducing CO2 emissions by 2050 because it is difficult to further improve brand performance. energy use rate.

According to researchers, the manufacturing sector has come a long way in improving energy efficiency, but the ability to save energy for many important production processes has reached a stable level. and it is difficult to go further.

Therefore, the goal of reducing CO2 emissions by 50% by 2050 set by the Intergovernmental Panel on Climate Change is impossible, especially when the demand for materials globally is expected. double.

Researchers have identified five of the most energy-intensive materials in production today: steel, cement, paper, plastic and aluminum; accounts for about half of the energy used and more than half of CO ₂ emissions in the manufacturing sector.

Since then, researchers have drawn an optimistic scenario in which each production facility applies the best available technologies in the hope of improving energy efficiency by 75% - but the results of the research team found only half that value.

Using other tactics, the research team then put more recycled materials into reducing energy consumption, but this has met with supply restrictions, especially in developing countries. grow at high speed.

Looking for alternative energy-saving materials is also not feasible due to the different properties of the material and more, the actual trend shows that we are replacing more energy-saving materials. in exchange for less energy-efficient materials.

Finally, the team concluded that the manufacturing industry could only reduce energy use by about 50% due to the thermodynamic limit of the material - ie the minimum energy required to produce a magnetic material. raw materials. So, even though the manufacturer has made great strides, the best technologies available are slowly reaching their limits, especially with the five types of materials studied, making reaching the target far away. More is extremely difficult and expensive.

However, according to researchers, we still need to find other ways to reduce energy consumption. For example, materials should be designed for longer use or for more people. This may help reduce the need for which energy consumption and CO2 emissions are reduced.
