Waste Heat Recovery System
1st cement company in the Philippines to invest in Waste Heat Recovery
A large amount of heat is produced in the production of cement. Only a small portion of this heat is utilized in the production process with most of the heat ending up being wasted. In 2010, we commissioned the Waste Heat Recovery System at the Republic Teresa Plant. This involved the installation of a 4.5MW capacity turbine which captures and uses most of the waste heat to generate electricity. This is the first of its kind in the Philippine cement industry.
The Heat Recovery System has the capacity to meet approximately 30 percent of Teresa Plant’s power requirements, thereby decreasing the plant’s dependence on the power grid and cutting our CO2 emissions by approximately 12,000 tons per year.
The Heat Recovery System is the only approved Clean Development Mechanism (CDM) project in the Philippine cement industry.
Total Ash Management
Coal-fired power plants burn coal to generate power. In the process, a by-product called fly ash is produced, which the power plants have to dispose in ash ponds. We are able to use all these by-products in our cement manufacturing process through our Total Ash Management Solution.
This Solution provides the most ecologically sound alternative to the current disposal of fly ash. Moreover, the use of this by-product as an additive in our cement provides a sustainable alternative to pozzolan, limestone, and other non-renewable materials. We are the first local cement manufacturer to pioneer this solution and remain the only company to use this alternative material as an additive in the production of blended cement.
Tubbataha Ranger Station
Led by the World Wide Fund for Nature (WWF), preparations for the construction of the new Tubbataha Reef Ranger Station in Palawan are expected to begin any time soon. To be built with Republic Type V marine cement specifically engineered for saltwater construction, this new state-of-the-art ranger station will replace the aging structure that presently houses the eight rangers tasked to patrol over 130,000 hectares of some of the most diverse marine ecosystems on Earth.
Water is fast becoming a scarce resource. We have to protect and enhance the cradle of our water supply – our watersheds. One of the watersheds closest to us is the Morong Watershed. Sadly, rapid development in Antipolo, Teresa and Morong is putting heavy pressure on the Morong Watershed.
In partnership with the World Wide Fund for Nature (WWF), we are working hand in hand with various government agencies and the local governments of Antipolo, Morong, Teresa and Rizal to develop a sustainability and management plan for the Morong Watershed to ensure its continued protection and conservation.
