Composting with CARBON/NITROGEN (C:N) RATIO
Human waste has a carbon to nitrogen ratio less than 10 parts carbon, whereas the optimum C:N ratio for composting human de-jecta (waste) is 20-30 parts carbon. A bulking agent with a high C:N ratio is therefore preferred, as this allows a smaller quantity of the agent to be used in comparison with other materials.
Representative ratios for commonly available bulking agents are shown below to indicate the relative ability of the materials to provide additional carbon.
