Cement Plants: Waste Fuels

Many cement plants have adjacent landfills as part of their quarry restoration programme, and in some instances, gas that would otherwise be burned is collected and used as fuel. Kiln fuel was supplemented by this means at both Norman and Swanscombe from 1983 onwards. The landfill must be carefully compacted and sealed to allow anaerobic decomposition to be established: even then, at least one

Environmental impact of concrete

The environmental impact of concrete, its manufacture and applications, are complex.Some effects are harmful; others welcome. Many depend on circumstances. A major component of concrete is cement, which has its own environmental and social impacts and contributes largely to those of concrete.. The cement industry is one of the main producers of carbon dioxide, a potent greenhouse gas.

Top 4 Environmental Compliance Issues at Concrete Plants

Surely a concrete plant doesn't release toxins, right? Well sort of. I'm going to assume your operation has an air permit, which allows your facility to discharge a small amount of air pollution (in the form of cement dust from your silos). Well it's no secret that cement contains some pretty nasty stuff in it, like lead and mercury, even if only in very, very small amounts. The problem

Cement and Concrete: Environmental Considerations

01/03/1993 There are approximately 210 cement plants in the U.S. and 4,000 to 5,000 ready mix plants (where cement is mixed with aggregate and water to produce concrete). The Portland Cement Association estimates that U.S. cement consumption has averaged between 75 and 90 million tons per year during the last decade, and projects that consumption will exceed 100
