Some embodiments are directed to a process for forming products from animal waste (e.g., poultry litter). The products may include a controlled release fertilizer and renewable natural gas. The process may include providing a feedstock comprising greater than about 80 percent poultry waste and a moisture content of about 25 percent. The feedstock may be diluted to form a slurry having a moisture content of about 90%. The slurry may be mechanically refined to reduce the particle size distribution and the average particle size of the slurry. The slurry may be anaerobically digested to produce biogas and a digestate. The biogas may be converted to renewable natural gas, and the digestate may be converted to a controlled release fertilizer. Additionally, some embodiments are directed to methods of reducing nitrogen emission from soil amendments. Some embodiments are directed to reducing nitrogen emissions sufficient to produce emissions offset credits.

Provided is a method of fixing a sufficient amount of carbon dioxide contained in a carbon dioxide-containing gas (e.g., a plant exhaust gas) simply, at low cost, and efficiently. The method of fixing carbon dioxide includes a contact step of bringing a carbon dioxide-containing gas into contact with powdery or grainy particles, which are each formed of a cementitious hardened body and each have a particle size of 40 mm or less, at a temperature of from 75° C. to 110° C. to fix carbon dioxide contained in the carbon dioxide-containing gas to the powdery or grainy particles, wherein the relative humidity of the carbon dioxide-containing gas is adjusted in accordance with the particle size of the powdery or grainy particles and the state of adjustment of moisture content of the powdery or grainy particles before the contact step.
