NOx, PM levels dive in latest EPA air quality report

Sources: U.S. Environmental Protection Agency; CP staff 

The federal government’s latest annual report on air quality trends, “Our Nation’s Air – EPA Celebrates 50 Years!,” documents pollution reduction progress from 1970-2019, emphasizing gains during the last few years. The combined emissions of Environmental Protection Agency-designated criteria pollutants and their precursors dropped 7 percent from 2017 to 2019. That metric reflects three-year declines in the emissions levels of nitrogen oxides, -10 percent; particulate matter 2.5, -1 percent; sulfur dioxide, -16 percent; carbon monoxide, -6 percent; and, volatile organic compounds, -3 percent.

CalPortland blended cement series clips carbon dioxide load

Sources: CalPortland Co., Glendora, Calif.; CP staff

The two charter offerings in a new CalPortland line of blended portland-limestone cements (PLC) have an embodied carbon level about 10 percent below that of common ASTM C 150 materials. ADVANCEMENT LT (Light) is a lighter colored, higher albedo Type IL PLC suiting concrete in design and architectural conditions. ADVANCEMENT HS (High Sulfate) is formulated for general use concrete or when high sulfate resistance is required.

Report chips away at wood industry’s low carbon building narrative

Sources: International Institute for Sustainable Development, Winnipeg, Manitoba; CP staff

A Cement Association of Canada-funded report exposes the limitations of life cycle assessment (LCA) studies whose results have thus far painted a more favorable greenhouse gas (GHG) emissions profile of wood versus concrete or steel buildings. As the main tools to measure building products’ carbon footprints at the production, use and end of life phases, LCA studies as presently executed can exaggerate the importance of embodied GHG impacts when they discount or ignore other significant life-cycle emissions, according to “Emission Omissions: Carbon accounting gaps in the built environment.”

Cement production undeniably minor in EPA greenhouse gas emissions census

Sources: U.S. Environmental Protection Agency; CP staff

U.S. portland cement production accounted for 2.3 percent of carbon dioxide-equivalent (CO2e) emissions in EPA Greenhouse Gas Reporting Program 2015 data. Modern kilns increasingly running on natural gas and other coal alternatives, coupled with limited offsetting import factors, appear to position the domestic cement industry favorably in a business often tagged as the source of 5 percent of global carbon dioxide emissions.

Automatic saw traverses Elematic EDGE program

CAPTION: The E9-500’s remote control adds flexibility to precast/prestressed production, while distancing the operator from the saw cutting and noise.

Elematic Inc. is presenting the E9-500 Saw as an accurate and multi-tasking unit for cutting prestressed products safely and cleanly. Company engineers characterize the model as the right solution for hollow core producers who need automated cross, longitudinal, and diagonal cutting of slabs having thickness of up to 20 in. (500 mm) with a single saw investment.
