The gasification plant produces energy and biochar from biomass

Biochar

BIOCHAR; ADDITIONAL RESOURCE OF OUR GASIFICATION PROCESS

When we use vegetable biomass to produce energy in a combustion process we give back the CO², previously captured from atmosphere, and produce ash that can be used in the topsoil, that contains mineral salts. With our system benefits for the environment are much more.

We transform biomass into synthesis gas with a process that supports itself, almost without using conventional fuels and we use gas to produce electricity, heating and cooling.What do we get from the process? Charcoal in huge quantities, that can be suitable to be incorporated into the soil as a soil improver, increasing its characteristics of permeability, porosity, aeration and ability to retain humidity.

In this way Biochar improves the soil from an agricoltural point of view;.«Until a century ago - says Franco Miglietta, a researcher of CNR Institute of Biometeorology in Florence – Italian farmland contained 130 tons of carbon per hectare, today almost half. 
Adding 700 kilos of biochar per annum, you may increase their fertility and store there for centuries the carbon dioxide, that plants have taken from atmosphere in order to grow.If, by assumption, this solution is adopted by the entire Italian agriculture, the country would take away 45 million tonnes of CO² per year from atmosphere.

For this reason more researches are focused on finding an economically and viable systems to capture and "kidnapping" the carbon dioxide, underground, produced by industry, to reduce greenhouse emissions into the atmosphere; CCS (Carbon Capture and Storage). In Italy there is a legislative decree, some patents, but no operational site yet. In other cases they have been used molecular sieves to capture the CO² that will be placed in the ground.Greenpeace, the worldwide environmental organization, said that the CCS is not a solution for energetic and climate problem; for several reasons. Meanwhile, at best, that technology is not expected to be available on an industrial scale before 2030.

In addition, CCS plants consume a lot of energy in turn, reducing efficiency of the plants to which they apply, and they have really high costs.As a viable alternative, the CNR and Greenpeace researchers support renewable energy sources, toward which the environmental organization proposes the investments diversion.

Otherwise our system, in addition of producing energy, supporting itself with a positive balance of energy and obtaining emission levels close to 0, allows to “kidnap” carbon dioxide from atmosphere and fixed in form of organic carbon in soil.

This is the answer to the past two decades of researches that combines so many expectations;

- Energy production from renewable sources (biomass)

- Reset of using fossil fuels

- CO² reduction

- Increase of the organic substance in soil and therefore of its fertility

As a practical example about the environmental benefits of our plant, we can say that we produce 4 MW of total energy with 1 ton of biomass (electricity, heating and cooling).This production, compared to a traditional plant, avoided more than 8000 tons per year of CO².We also fix into the ground, through biochar, 400 kg. of CO² per ton, that plants had absorbed from the atmosphere.

BENEFITS AND MANY USES OF CHARCOAL

Benefits of biochar useDifferent studies have demonstrated significant agronomic benefits, such as increased crops production, inside soils improved with biochar. Its application helps to improve the fertility of the soil and to increase water and essential nutrients retention for the plants, in particular calcium, potassium and phosphorus. 
Thanks to its porous structure and a high surface area, Biochar influences the physical properties of the soil, for example by helping water retention and by increasing the surface area.

Another positive effect is the increase in the pH of the soil, caused by the presence of basic substances in the char. This is particularly useful in acid soils, in which the increase of pH leads to an increase of the solubility of important elements for plants, such as phosphorus, calcium and potassium.Also, after placing in the ground, the surface of the char undergoes oxidation with the formation of carboxylic and phenolic functional groups, that confer negative charges pH dependent to the surface.
