Biochar is a waste product from gasification
The main "waste" product from gasification is charcoal. For every pound of chips you put in, you get about .5 pounds of charcoal out the bottom. Importantly, this charcoal, has a plethora of uses: it can filter water, it can be used as a secondary fuel source (it cooks veggie brats nicely!), or it can be used to create Terra Preta or Bio-Char. - Read More

Existing markets for hydrogen
There are two substantial existing markets for hydrogen: 1. Petroleum refining uses H2 to upgrade larger and heavier molecules in crude oil to the smaller hydrocarbons in gasoline; 2. H2 is eracted with atmospheric N2, using a nickel catalyst, to form ammonia, which is in turn used in fertilizers

The basic concept is that the toilet has two receptacles for the different kinds of waste. - Read More

Fertilization of Lands
On nitrogen-deficient lands, fertilization could probably increase crop (biomass) production hundreds of percents. An increase in agricultural productivity per unit area (land) could make it possible for some of the farm lands to return to forests, which can be a positive contribution to global CO2 sequestration.
