Biochar and activated carbon: two recovery products not to confuse

Carbonization can produce a material useful for soil or energy; activation targets stronger adsorption properties for specific uses.

The process defines the properties

Feedstock, temperature, duration, atmosphere and possible activation determine porosity, surface area and product behavior.

Depending on quality and context, it can be directed to soil amendment, densified fuel or selected treatment functions.

It is valued for adsorption and must be characterized according to the pollutants and treatment process considered.
