Seeking Innovations for more sustainable construction

Seeking Innovations for more sustainable construction

At CEMEX, we are constantly seeking ways to help our customers build more sustainable structures and, in doing so, reduce their—and our—environmental impacts. While concrete’s properties make it a good choice for building more energy-efficient structures that need little or no maintenance over their useful lives, we work through our Global Center for Technology and Innovation to develop new and innovative products that contribute to more sustainable built environments and reduce greenhouse gas emissions in the process.

Eco-labeled Rizal Green Cement Aids Sustainable Construction in the Philippines

We recently launched our Rizal Green cement, an all-purpose masonry cement that can be used for both masonry works and semi-structural projects such as driveways, fences, and ground-floor slabs for residential construction. The result of more than two years of laboratory and market research, Rizal Green has a patented formulation that reduces CO2 emissions by up to 32% when used as a substitute for ordinary Portland cement in masonry works.

In the short time it has been on the market, Rizal Green has become the brand of choice among contractors and builders in the Philippines; it facilitates construction through excellent workability and reduced application times. Rizal Green is among several CEMEX products that bear the Green Choice eco-label seal in the Philippines, which means that we manufacture our products in a manner that avoids detrimental effects on the environment ensuring that every step in our production process complies with the standards set by The Philippine Center for Environmental Protection and Sustainable Development, Inc. (PCEPSDI).

In the UK, our products offer a certification on carbon labeling and responsible sourcing

CEMEX UK is the first cement company in the world to provide certified carbon labels for its cement. The carbon label, which incorporates the Carbon Trust's Carbon Reduction Label, shows that, depending on product composition, CEMEX cements generate between 17 to 24kg of CO2 per 25kg bag.

The carbon footprint is the amount of CO2 and other greenhouse gases (CO2e) generated by our cement throughout its life cycle: from the extraction of the raw materials, to manufacturing, distribution, use by customers, and disposal at the end of life. The carbon footprint of our cement is certified to the PAS2050, the first international standard for companies to measure the carbon footprint of their products and services. The development of the PAS2050 standard was overseen by an independent steering group comprising NGOs, academics, business, and government representatives.

In addition, CEMEX UK's cement division has also been certified to the Building Research Establishment (BRE) Framework Standard for the Responsible Sourcing of Construction Products—BES6001 with a score of 'Very Good'. CEMEX is among the first in the industry to meet the standard, which covers all of the company's three UK cement plants as part of its efforts to meet the requirements of the Government's Strategy for Sustainable Construction.

This certification means that all cement supplied by CEMEX UK is certified as responsibly sourced to an independently verified standard that addresses the social, economic and environmental impacts across the entire supply chain.

To meet the standard, CEMEX's cement products were assessed in accordance with quality, organizational governance, supply chain management, and environmental and social impact. The certification also allows for traceability of the product to ensure that all areas within the supply chain are operating to high standards. CEMEX plans to extend the Responsible Sourcing certification to its entire business.

In this country, we are pioneering the use of recycled materials to produce blended cement which, in turn, is used to produce concrete. Designated CEM2 to distinguish it from CEM1 products that are made only with clinker, this innovative product is a factory blended Portland composite cement that reduces landfill by reusing fly ash, a by-product of coal-fired power plants in its production process. CEM2 avoids CO2 emissions by 25% per metric ton of cement produced. The CEM2 logo indicates that the product contains recycled materials.
