AUSTRALIA delivering commercially superior solutions to their customers while installing state-of-the-art equipment and processes to ensure the most efficient manufacturing , with significant attention being paid to environmental protection .
In its mission toward sustainability , Holcim focuses on limiting the environmental footprint of its production , specifically in regards to energy and water usage for producing each ton of cement .
With a commitment to make major investments in the latest technologies , Holcim intends to develop an energy-efficient culture within its staff by embedding energy efficient habits of consumption into their daily work .
This will be accomplished by upgrading current equipment to reduce the volume of electrical and thermal energy used , substituting fossil fuels with alternative fuels to generate fewer CO2 emissions and using mineral components in all products to preserve the quality expected by its customers . One of Holcim ’ s largest investments is the company ’ s
Waste Heat Recover ( WHR ) Power plant , which has been operating since 2012 . The steam-cycle plant is among the first in Vietnam to use heat from the production process to generate electrical energy .
The plant uses two waste heat sources : a kiln preheater exhaust and a clinker cooler exhaust . Since the WHR plant meets 25 per cent of the plant ’ s electricity requirements , it takes pressure off the national grid supply and significantly reduces CO2 emissions by an estimated 25,000 tonnes per year . This provides massive benefits to the environment , economy and society as a whole .
Some of the company ’ s other investments include using a Vertical Roller Mill ( VRM ) to reduce energy consumption in cement production , installing bag filters to reduce dust emissions and perfecting co-processing technology in Hon Chong cement plant . Using co-processing in cement kiln technology , Holcim developed its operation using considerable investments in new technology for its co-processing actions at the Hon Chong cement plant .
