AAC blocks manufacturing based on energy efficient technology
Avoidance of CO2 emissions through more efficient production
Budge-Budge, Kalkutta, INDIa*
Biltech's project activity is an initiative to produce 200,000 cubic meters of AAC (Guest Concrete Blocks) blocks at Budge-Budge, Kolkata (Calcutta).
The core of this technology is the special composition of the guest concrete blocks, their chemical constituents.
A blend of fly ash from thermal plants, lime, cement, gypsum and aluminum powder. This formulation allows the blocks to acquire the mechanical properties required during the hydration and hardening process without sintering (alteration of the material in the consolidation process).
This project is also focused on increasing energy efficiency in the production of building materials. Conventional energy sources are replaced by environmentally friendly gas, and kilns whose firing was previously oil can be shut down.
This project also helps India reach the Paris climate targets.
Climate protection taken seriously - through own fossil-fuel phase-out
According to the Climate Protection Index 2017 (Germanwatch), India ranks with place 20 nine places before (!) Germany in the international climate change ranking. And though India is one of the ten largest carbon emitters due to its population of 1.3 billion, its per capita emissions are still at a relatively low level. However, the country’s emissions are currently rising fast. About 25 percent of the increase in power consumption is covered by renewable energies, but there is still enough room for improvements.
India’s government intends to quadruple the share of renewable energies by 2022. Today, power from solar panels is already the cheapest source of energy in India. All coal-fired power stations should be dismantled by 2026. In 58 developing countries, including India, wind and solar energy is now cheaper than fossil-fuel power. (Bloomberg)
With our climate protection projects from India, we support climate protection efforts of the central government, which has been a true pioneer in the past for years, compared to Germany. Germany as alleged climate protection pioneer today and probably also the next decades, is funding the brown coal distribution with billions of public money.
