Italcementi plans to combine bio and fossil fuels effectively

Recently, the Italcementi group unveiled a new plan to supplement their fossil fuel consumption with renewable fuels. These new fuels are coming from algae grown on site at their Gargenville, France plant.

The benefits of such a system as this are three-fold. The first benefit is the fact that less carbon dioxide is being released in the air. Secondly, the algae can be dried and used as a partial replacement of the plant’s fossil fuels. Finally, waste heat from the plant can be used during the drying process instead of being discharged to the atmosphere.

A stone for CO2: useful for cement industry

Iceland is experimenting with pumping carbon dioxide underground and converting it into rock

Researchers are now pumping CO2 underground in a process that will convert the greenhouse gas into rock. This technique may be a model for other power plants and cement plants to control their emissions, creating a climate change solution literally set in stone.
