Background
- China is a major global supplier and consumer of refractories.
- The environmental impact of refractory production has gained significant attention.
- Refractory manufacturing contributes to air pollutant and carbon dioxide (CO2) emissions.
Purpose Of The Study
- To quantify life cycle air pollutant and CO2 emissions from China's refractory industry (2009-2021).
- To identify the driving forces behind emission changes.
- To project future emission reduction potentials.
Main Methods
- Life cycle emission quantification for particulate matter, SO2, NOx, and CO2.
- Logarithmic Mean Divisia Index (LMDI) model to analyze emission drivers.
- Scenario simulation for future emission reduction projections.
Main Results
- Despite stable output, particulate matter, SO2, and NOx emissions decreased by 7.1%, 23.6%, and 27.8% respectively.
- CO2 emissions were reduced by 1.36 million tons due to product modifications.
- Industry shift from clay bricks to less polluting refractories contributed to emission reduction.
Conclusions
- Technological advancements and industry shifts significantly reduced refractory manufacturing emissions in China.
- Potential for substantial further emission reductions (23.1-77.7%) by 2030 exists.
- Policy and technological innovation are key to sustainable refractory production.

Carbon is the basis of all organic matter on Earth, and is recycled through the ecosystem in two primary processes: one in which carbon is exchanged among living organisms, and one in which carbon is cycled over long periods of time through fossilized organic remains, weathering of rocks, and volcanic activity. Human activities, including increased agricultural practices and the burning of fossil fuels, has greatly affected the balance of the natural carbon cycle.

Steel manufacturing is a multi-stage process that begins by smelting iron ore into cast iron in a blast furnace. This initial stage involves layering iron ore with coke, a type of fuel, and crushed limestone within the furnace. The coke is ignited with a high volume of air, leading to the creation of carbon monoxide, which acts to reduce the iron ore to pure iron.
During this smelting process, limestone plays a crucial role by forming slag. Slag captures impurities within the molten iron, such...
