“Going green” is a buzzword these days. The same also applies to the construction industry. It is estimated that the CO2 emission from construction industry accounted for 23% of the total CO2 emission in 2009.
Thus, there is a need to take environmentally friendly measures in the construction sector to keep the carbon footprint at a minimum. The cement that is widely used in the construction sector has a vital role to play in environmental pollution.
How does the cement industry affect the environment?
The cement industry affects the environment in many ways. Right from its manufacture to the final transportation to the site, the cement industry is negatively affecting the environment. Here are a few ways the cement industry is contributing to global warming.
Different types of gases and dust are emitted when cement is manufactured, thus negatively impacting the environment. When the limestone is heated for making cement, it results in the release of CO2. Similarly, when fossil fuel is heated to burn the kiln, then also CO2 is emitted into the environment. All of this results in air pollution.
The production of cement results in the emission of carbon dioxide. This can affect the climate in the area. Moreover, if the energy used in the production is sourced from fossil fuel, it will also negatively affect the climate of the region.
The vibration and noise caused by the various machinery in the cement industry contribute to noise pollution. In addition to this, the blasting in limestone quarries also contributes to noise pollution.
Depletion of natural resources
Cement is manufactured by heating limestone, which is a natural resource. Similarly, coal, oil, and natural gas used for burning the kiln are also natural resources. Thus, large scale production of cement results in higher depletion of natural resources.
How can this be reduced?
It is the collective responsibility of all engaged in the cement industry to ensure that the green protocol is followed in every stage of cement production.
Using environment-friendly equipment
Equipment that is environment-friendly and which helps in reducing the dust during quarrying and cement production should be used. Even the limestone quarries should also be selected wisely after considering the environmental factors.
Recycling concrete material
Another method is to reuse or recycle the concrete material made from cement. Recycling and reusing help in reducing the construction waste and the quantity of material that ends up in the landfill. Concrete can be recycled by crushing it into small pieces and reused for construction activities. Concrete supply companies provides recycled concrete for constructing pavement, parks, and streets.
Use of dry kiln
Yet another effective method that can be adopted by cement suppliers is to use the dry-process kiln for manufacturing cement instead of wet or semi-wet process kiln. This helps to reduce energy consumption and CO2 emission.
Using pervious concrete
This type of concrete helps in retaining the moisture of the ground underneath.
What is pervious concrete?
Pervious concrete is a porous concrete that allows water to seep through it. Thus, it helps in recharging ground water. This type of concrete is mostly used for outdoor construction work like parking area, pedestrian walkway, and streets.
What are its advantages?
Compared to standard concrete, pervious concrete offers the following advantages.
It is porous.
The traditional concrete does not allow rainwater to seep through, thus leaving the area underground dry and parched. Pervious concrete, on the other hand, allows water to seep through thus providing enough moisture to the soil. This is particularly useful for construction in agricultural land where retaining the moisture of the soil is very important.
It helps in effective surface management.
Using pervious concrete in lowland areas helps in controlling the incidence of flood. As the flood water can drain through the soil, there is no water logging on the surface. As a result of this, there is no choked sewerage and the resulting damage.
It controls pollution.
Since the water seeps through the pervious concrete, the pollutants in it gets caught in the pores. Thus, there is a lesser chance for external contamination.
It avoids heating of surrounding area.
When traditional concrete is used in pavement and paths, it absorbs a lot of heat. This increases the temperature in the surrounding areas thus affecting the overall ecosystem. Pervious concrete has an open cell structure and light color because of which it does not absorb heat. Hence, there is not much change in the temperature of the surrounding areas. Thus, the overall ecosystem is not impacted, and a cool ambiance can be maintained.
It helps in the better utilization of land.
When pervious concrete is used, there is no need for a separate stormwater drain as the concrete itself is porous. Thus, there is no need to procure additional land for the filtering system. This also helps in reducing the project cost.
It is long lasting.
Just like the normal concrete, pervious concrete also lasts for a long time, if maintained properly. It does not rust, fade, or rot and is highly durable. Thus, there is no need for renovation work which would have otherwise impacted the environment.
