Eco Friendly Rock Wool Boards Sustainable For Green Buildings

Eco-Friendly Rock Wool Boards Sustainable For Green Buildings

As a new-type material aligned with modern environmental protection concepts, rock wool boards embody green properties throughout their entire life cycle and meet the needs of various fields. In terms of raw materials, they mainly use natural rocks such as basalt and diabase, giving priority to low-grade rocks to avoid the waste of high-quality resources. At the same time, they incorporate 20%-30% of industrial solid wastes like blast furnace slag from iron and steel plants and fly ash from power plants. For every ton of rock wool boards produced, approximately 0.3 tons of waste residue can be consumed, effectively reducing land occupation and pollution caused by solid waste accumulation and realizing resource recycling.

Performance

In the production process, rock wool boards are manufactured through processes such as high-temperature melting (around 1,500°C) and centrifugal fiber formation. Although high temperatures are required, modern production lines mostly adopt clean energy and apply heat recovery technology, reducing the energy consumption per unit product by more than 30% compared with traditional processes. No toxic additives such as formaldehyde or benzene are used during production, only a small amount of environmentally friendly binders. After treatment, the emission of pollutants from waste gas is far below the national standard, and the recycling rate of wastewater reaches 100%, achieving low-energy and low-pollution production.

The application stage is the core embodiment of its environmental value. With an extremely low thermal conductivity, when used as a building insulation layer, it can reduce winter heating energy consumption by 40%-60% and summer cooling energy consumption by 30%-50%, significantly cutting down energy consumption and greenhouse gas emissions. Meanwhile, its fibrous structure can achieve a noise reduction of 20-30 dB, effectively improving the acoustic environment. In the industrial field, applying it to equipment and pipeline insulation can reduce heat loss by more than 90%, enhancing energy utilization efficiency; it can also be processed into filter materials for flue gas dust removal. In the transportation field, using it for insulation in automobiles and ships can reduce air conditioning energy consumption and lower exhaust emissions; when applied in high-speed rail carriages, it can reduce traffic noise.

Benefits

After being discarded, rock wool boards have stable chemical properties and do not release toxic substances when buried in soil. Their main components can be naturally degraded, and they can be crushed and re-incorporated into raw materials for recycling. Even if landfilled, they will not cause significant pressure on the environment. In addition, their Class A non-combustible property can reduce the risk of building fires and toxic gas pollution, and their service life of 20-30 years can reduce material consumption and construction waste. In summary, through the full-life-cycle closed loop of "resource recycling - low-energy production - energy-saving application - harmless disposal after abandonment", rock wool boards have become an environmentally friendly material that supports the "dual carbon" goals (carbon peaking and carbon neutrality) and has multiple advantages.
