In this work, the application of biochar from gasification as soil amendant, is studied. The effect on Ocimum basilicum growth with three different substrates was investigated: standard soil as the control sample, soil with 30% wt. of compost added, soil with 30% wt. of biochar added, which biochar was obtained as by-product of a fixed bed gasification process. Five samples for each of the substrates were used in order to increase the statistical validity of the results. 55 days of Ocimum basilicum growth showed that the biochar contributed to an acceleration of the growth and increased the fresh and dry weights with about 50%. In addition, plant height and essential oil content was higher with biochar-based substrates. This application can lead to more efficient and sustainable agricultural processes, giving new impulse to bio-energy production and recycling of by-products in a circular economy context.

Abstract
In this work, the application of biochar from gasification as soil amendant, is studied. The effect on Ocimum basilicum growth with three different substrates was investigated: standard soil as the control sample, soil with 30% wt. of compost added, soil with 30% wt. of biochar added, which biochar was obtained as by-product of a fixed bed gasification process. Five samples for each of the substrates were used in order to increase the statistical validity of the results. 55 days of Ocimum basilicum growth showed that the biochar contributed to an acceleration of the growth and increased the fresh and dry weights with about 50%. In addition, plant height and essential oil content was higher with biochar-based substrates. This application can lead to more efficient and sustainable agricultural processes, giving new impulse to bio-energy production and recycling of by-products in a circular economy context.
