Mineral carbonation of alkaline waste materials is being studied extensively for its potential as a way of reducing the increased level of CO2 in the atmosphere. Carbonation converts CO2 into minerals which are stable over geological time scales. This process occurs naturally but slowly, and...

Traditionally, voluntary measures have been evaluated using the same framework regardless of their structure. The framework assumes that the measure provides partners with a treatment (information, research support, etc) that will not be transferred to nonpartners. In this framework, a voluntary...

The framework for voluntary program evaluation assumes that voluntary programs provide partners with information that will not be transferred to non-partners. In this framework, a voluntary program is said to be worthwhile if there are significant differences between the behavior of partners and...

Carbonation of magnesium silicates offers an interesting option for CO2 emission mitigation in Finland, a country with large resources of serpentine-type minerals. Wet processes using aqueous solutions show reasonable chemical kinetics combined with poor energy economy. A dry, gas–solid...

Mineral carbonation presents itself as the most promising method to sequester CO2 in Finland. A staged process for CO2 mineralisation, using magnesium silicates, is being intensively developed at Åbo Akademi. A process energy analysis is made based on the most energy intensive steps, i.e. the...

In this study, the technical feasibility of the mineral carbonation of flue gas desulfurization (FGD) gypsum to sequester CO2 was assessed by considering various reaction parameters. Unlike other natural and industrial materials, FGD gypsum showed very high carbonation reactivity at room...
