Nitrogen Ratio Calculations
- 23:1 to 10:1 carbon to nitrogen ratio is acceptable in feedstocks - [1]. Nitrogen concentration of up to 5g/L are acceptable.
- Peeing 10x and flushing with one gallon - 10 gallons of input can handle up to 200 g of nitrogen in that input, assuming adequate ratios of carbon were available.
- Americans produce 90M gallons of urine per day, with 7M lb nitrogen. [2]. Per capita urine is thus 0.02 lb per day, or 9 grams. If urine is caught in a biodigester only during defecation, and other times it can be flushed separately, then only 1-2 grams of nitrogen would enter the biodigester per person from urination.
