About Construction Material Consumption in US., You Have to Know

  • US raw material (non-fossil fuel or food) use rose 3.14 times more than the population from 1910 to 2014.
  • After rising 62% from 1970 to 2005, total material consumption in the US (including fuels and other materials) reached 6.0 billion metric tons in 2017, which is still 12% higher than 1970 levels of material consumption.
  • In 2017, US per capita total material consumption (including fuels) was 18.6 metric tons, 42% higher than Europe.
  • After increasing by 30% from 1996 to 2006, US raw material use decreased 33% from 2006 to 2010 following the global financial crisis.
  • Construction materials, including stone, gravel, and sand, account for around three-quarters of raw materials use.
  • The use of renewable materials decreased dramatically over the last century—from 41% to 5% of total materials by weight—as the US economy shifted from agriculture to industrial production.
  • The ratio of global reserve to production rate is an indicator of the adequacy of mineral supplies; it can range from a few centuries (aluminum, chromium, lithium, platinum, phosphate rock), to several decades (copper, gold, iron).
  • Rare earth elements (REEs) are a group of 17 elements used in metal alloys, batteries, and as catalysts, with 75% used as catalysts. Substitutes for REEs are available, but are less effective. China controlled more than 58% of REE production in 2020.

About Construction Material in China

The construction industry is one of the fastest consuming industries in China, and its energy consumption accounts for more than thirty percent of the total national share. Every year, China's new housing construction area in urban and rural areas is nearly 2 billion square meters, of which more than 80% are high-energy-consuming buildings; existing buildings are nearly 40 billion square meters, and more than 95% are high-energy-consuming buildings.

At present, China's energy consumption per unit of floor space is more than 2 to 3 times that of developed countries, so the government's efforts to implement energy-saving and emission reduction policies are gradually increasing, and several building energy-saving standards are proposed, aiming to promote and regulate the development of energy-saving building materials. Now, there are many kinds of building thermal insulation materials appearing in the market and being researched, which can be divided into 2 categories in terms of material composition, one is inorganic thermal insulation type materials, such as aerated concrete, glass fiber, rock wool, etc.; another is organic thermal insulation materials, such as extruded polystyrene board and polystyrene particles, etc. But at present, the traditional insulation materials generally have certain problems in the comprehensive insulation effect.

Traditional insulation materials in buildings have such weakness,

  • Low thermal insulation efficiency, energy saving and emission reduction effect is not significant.
  • Poor environmental performance, difficult to dispose of the product after disposal and pollution of the environment.
  • Poor hydrophobic performance, large deformation coefficient, short service life.
  • Part of the material is not fireproof, and easy to release toxic and harmful gases at high temperatures.

Compared to mentioned above, Sino-Aerogel Insulation Materials have such advantages, 

Sino-Aerogel SA450 Thermal Insulation Material Blanket Aerogel | Mid-Temperature Collection

  • Low thermal conductivity, good insulation performance, thin insulation layer thickness, space-saving.
  • Good fireproof and hydrophobic performance, long service life.
  • Safe and environmentally friendly, harmless to the people.
  • Porous structure, high specific surface area, sound insulation and noise reduction, creating a comfortable environment.
  • Easy to cut, convenient construction, reduce construction cost.
