STARTUP STORY
Many of us focus on plantation drives and opting for environment-friendly products to reduce carbon emissions. But in the process, we tend to overlook, or are unaware altogether, that the very walls surrounding are in our homes are also massive contributors to climate change. Gravel, sand, and cement extracted from the earth and mixed together with water have created a recipe for disaster.
Raw material such as limestone and clay comes from quarries. The material is crushed and mixed with iron ore or ash and fed to cylindrical kins at around 1,450 degrees Celsius. The process is called calcination, which splits the mixture into calcium oxide and Co2, giving out a new product called clinker. The new marble-sized and grey product is cooled and mixed with gypsum and limestone and sent as a ready-mix to concrete companies.
Half of the Co2 emissions from cement happen during the process. If cement were considered a nation. It would become the third-largest Co2 emitter in the globe, surpassing a massive country like India.

But a Roorkee and Vishakhapatnam-based social enterprise, Greenjams, might just have an alternative. the startup is creating carbon-negative building material from agriculture biomass and help blocks.
They made a product which is called Agrocrete, It made up of upcycled material and can reduce construction costs by 50%, increase thermal insulation by 50%, and cut down the time required for constructing buildings.
The startup solves the problems of crop residue burning, which costs the country almost 2 lakh crore rupees annually on health-related expenditure, and the carbon emissions from the built environment, which countries to almost 45% of global carbon emissions because of space conditioning of buildings and manufacture of construction materials.
