USA – Changing cement, changing emissions for the better

24 November 2003, Published under Cement News

The Portland Cement Association announced the latest effort by the industry to significantly reduce the emissions burden on the environment. Tom Chizmadia, PCA board member and chairman of its Environment and Energy Committee, outlined the change in Portland cement production by including up to five per cent ground limestone in ASTM C 150 Portland cement. Chizmadia stressed the importance of this move: “Such reductions could add significantly to the environmental gains already achieved by th...

Asia – Curbing global warming the Asian way

17 November 2003, Published under Cement News

Asia’s cement producers are contributing in global climate regulation by replacing coal with rice husks that would otherwise be incinerated and dumped in landfills. While rice husks do release carbon dioxide into the atmosphere, supporters say that sulphur emissions are around one-fifth of coal and lignite. Moreover, rice mills were burning the husks anyway, so net carbon dioxide emissions are predicted to fall as a result of the switch. In addition to the fuel advantages, the ash of...

USA – Rare flower discovered on former aggregate site

17 November 2003, Published under Cement News

When RMC South Florida Inc donated its aggregate site to Florida International University little did the company know that the site held botanical treasures. Preliminary research by the university has resulted in the discovery of two populations of bracted colic root (Aletris bracteata), a world endangered species related to lilies. That the discovery is a rare find is illustrated by the fact that it occurs only in Florida’s Dade and Monroe Counties, apart from the northern islands of the Bah...

Ireland – Proposals for use of animal waste in cement

17 November 2003, Published under Cement News

In a report to the Irish Cabinet, senior officials of four government departments, the Environmental Protection Agency and the Food Safety Authority, recommend the incineration and incorporation into cement of meat and bonemeal – considered a potential source of BSE – from slaughtered Irish cattle. Curently, meat and bonemeal is mostly sent abroad to countries such as the UK and Germany for incineration or is stored within the country, costing the local taxpayer around E150m in the past...

USA – Tyre burning plans at Lafarge Ravena, NY

10 November 2003, Published under Cement News

Lafarge North America plans to burn tyres at its Ravena cement works with the aim to reduce its use of coal as thermal energy source and possibly cut emissions. The plans outline the initial burning of tyres in one kiln in 2005. Retrofitting of the plant’s second kiln by the following year should enable the company to push up tyre disposal levels to 6-8m tyres annually. This would mean coal and other fuel consumption would be reduced by 20 per cent, leading to a seven per cent cut in pro...

USA – Senate rejects plan to limit GHG emissions

10 November 2003, Published under Cement News

While Europe gears up for carbon emission trading, the US Senate has rejected a market-based scheme to reduce the country’s emissions of carbon dioxide and other greenhouse gases. With a 43-55 vote, the Senate defeated the Climate Stewardship Act, which proposed a cap-and-trade system, designed to cut greenhouse emissions back to 2000 levels by 2010. The proposed law would limit CO2 emissions from power plants, vehicles and factories.

Businesses affected by the trading scheme must obtain a permit from the Environment Agency by 31 March 2004. The first phase of the new emissions regime (2005-2007) will focus on carbon dioxide, a major contributor to climate change that coul...
