I'm a student of Environmental Engineering and i'm writing a thesis on the Urban Biorefinery. The biochar derived by the pyrolysis conversion of the solid fraction of digestate of OFMSW results rich in Heavy Metals, and i'm thinking about a possibility of using that as soil improver for the Vetiver's cultivation that has a great capacity of adsorbing heavy metal.

In my opinion it could represent a barrier against a possible heavy metal's leaching in the soil.

Thanks in advance for your kind reply.
