1. A method of removing acidic gases from wet air streams comprising putting an adsorbent comprising
a) a waste material composition, comprising:
one of compost or compost materials and sludge;
(1) wherein the compost is one of tobacco waste, waste paper, wood char or a combination thereof;
(2) wherein the sludge is at least one of waste oil, metal, or municipal sludge;
(ii) 20-30% porous organic carbon with incorporated organic nitrogen species; and
(iii) 70-80% inorganic matter;
b) adsorbent characteristics, wherein;
(i) the adsorbent is capable of adsorbing up to about 30% of the adsorbent's weight in hydrogen sulfide;
(ii) a surface area of the adsorbent is 10-200 m2/g; and
(iii) the pH of the adsorbent is between 7-12;
in contact with the wet air stream and allowing the adsorbent to adsorb the acidic gases.
