Ek bangla banei nyara ( lets make one beautiful house)
So after that degree ,internships,job placements and that years of saving most of us go for that one big dream — Home.A lot of us find making our own home as an important leveling up in life. The more houses one owns , stronger is considered their economic hold .
And their is absolutely nothing wrong with that as everyone wants to measure their happiness ,sometimes in materialistic things.
The question is how do you build your houses ,
Is your dream of building a house in some way ruining your child’s future. Let us take a look
STATEMENT
If cement -concrete were a nation, it would be the third largest emitter of CO2 after US and China.
HOW
Concrete is made of limestone. Limestone is a fossil carbon made of millions of sea shells of tiny creatures over eons of time.We break apart these chemical bonds by burning fossil fuels , allowing them to achieve super high temperature and release CO2 in the air.
SOLUTION
Clays produce very reactive material when heated to around 800°C ,significantly lower than 1450°C ,used in previous method to produce cement (plus there is no CO2 emission from decomposition of limestone)
Now we take this heated clay(Calcined clay) ,add a bit of limestone without heating(so no CO2) and some cement and we call this. - "LC3"
This substance is equally strong as cement and produce 40% less CO2.
WHY
We have 10 years to flip this climate change story to save our civilization. Global pollution contributions by cement -concrete is 8% .If we continue our old ways of functioning in association to CO2 emission, we not will damage our lungs tissues and create serious threat to asthmatic patients but will also pose threat to national security, food security which in turn can lead to resource conflict.
Now i know that you are thinking that one person cannot change the entire market functioning and its not just housing but almost everything that is build around us , sure ,but if you just start demanding , asking question,
We will eventually start this change — first in thought process and then in our surroundings.
