چکیده
Climate change has been identified as one of the biggest issues plaguing human life at present. Hence, immense attention is being paid to developing methods that can potentially reduce carbon dioxide emission. With help carbon-negative concrete, manufactured from alternative binders and cured with waste dioxide, a major part manufacturing industries emit be turned into sink. In this study, material streams in Finland, suitable for disposing carbon-dioxide-cured were mapped. Mine tailings, blast furnace steel slags, recycled biomass, coal municipal incineration ashes, green liquor dregs, foundry sands studied. It was found there sufficient amounts potential secondary raw materials (about 27 Mt/a) preparation Finnish cement production concrete (requirement: approximately 1.4 Mt/a 11.2 Mt/a, respectively). The total uptake estimated 1.9 (vs. emissions industry 0.84 Mt/a). addition, footprints conventionally block compared footprint produced by modeled slag block. If such novel used produce all concrete-based substances, it would bring down emission 1.9% negative 1.3% Finland.

Reducing Carbon Dioxide Emissions
DEBATE ABOUT the increasing concentration of carbon dioxide (CO2) in the atmosphere, and fears that it will result in an intensification of the Greenhouse Effect and global warming, have spurred consideration of sustainable development. It has been claimed that technology to improve energy efficiency already exists that is cost-effective without consideration of the gains from abatement of carb...
متن کاملSequestration of Carbon Dioxide Emissions
Background The world's oceans represent the largest potential sink for the carbon dioxide (CO 2) produced by human activities (anthropogenic CO 2). Already oceans contain the equivalent of an estimated 140,000 gigatons of CO 2. The ocean's natural carbon transfer processes span of thousands of years and will eventually transfer 80-90 percent of today's man-made CO 2 emissions to the deep ocean....
متن کاملAccounting for Carbon Dioxide Emissions
It is an adage of accounting to monitor what you can measure but there is concern that some elements can potentially be very important yet very difficult to evaluate. There are now many who care about accounting for CO2 emissions: from scientists interested in the global carbon cycle to environmentalists concerned about global climate change, regulators overseeing international or subnational a...
