While most people practice sustainable habits with reusable grocery bags, other folks get it done slightly more creatively! As one of the largest coal mining organizations globally, AngloAmerican most recently started purifying water that had been contaminated as a result of the company’s mining ventures. Based upon a CNN.com report, the South African organization is making efforts to maintain the environment by constructing eco friendly housing by using the industrial waste content. The business is using a by product known as gypsum to build cost-effective as well as energy efficient structures. AngloAmerican is combining gypsum with cement to manufacture eco-friendly bricks to construct structures in the city of eMalahleni. Incredibly, the name eMalahleni actually translates to ‘city of coal’ in Zulu.  

Progress made by AngloAmerican

The action was taken by Peter Gunther, the company’s head of sustainable development. AngloAmerican has fabricated 62 houses in the city thus far. Each and every residence must have about 8 tons of gypsum and the organization is accumulating over 200 tons of this waste by-product daily. eMalahleni is one of the fastest developing urban areas in the country and utilizing eco friendly substances to construct new dwellings is a huge step in the right direction. The company began building housing with gypsum infused bricks for its employees in 2010. AngloAmerican eventually proposes to construct homes for all its workforce with four hundred homes slated for 2012.

Why gypsum?

Deficiency of housing and also the large quantity of gypsum got the company thinking before it proceeded to build environmentally friendly dwellings with safe waste by-products. Gypsum is a basic material which has minerals such as calcium and sulphur. This mineral matter is non toxic but soluble in water. A unique property of gypsum is that it gets much stronger plus more adhesive as it gets dryer and hotter. Gypsum is not as strong when it is wet. The flexible properties of gypsum make it most useful as household plaster. Gypsum is furthermore utilized in many other industries, for constructing fireproof doors as well as in dental procedures and surgery.  

Gypsum is traditionally used because it’s a robust binding agent which reduces the volume of cement necessary to make the same number of bricks. It is estimated that the decreased specs for cement is reducing in excess of 3 tons of carbon dioxide for every residence. Gypsum is a readily found mineral in the world and is an ideal insulator of heat and it’s also physically strong provided that it’s completely dry. As it is water soluble, the utilization of gypsum in cement bricks was typically questioned. Gunther reasons that considering that the bricks are also composed of cement, they are water resistant.  

How efficient is it?

Peter Gunther states that the new bricks fabricated with a mix of cement and also gypsum have advantages over typical cement bricks. The combination bricks are likely to be harder in addition to lighter than common cement bricks. Gypsum also will allow these bricks to be much better insulators of sound and heat. Such bricks are easier on the environment as they lessen the demand for cement. It’s estimated that cement production results in 5% of the carbon dioxide emission, that’s proven to speed up global warming.
