A big problem: Animal manure from farming
People love to eat meat, eggs, and dairy. Cows, pigs, and chickens will be a part of the human diet until replacements are found and implemented worldwide. These animals produce immense quantities of manure.
Manure slowly decomposes and gives off two important greenhouse gases: methane and carbon dioxide.
Manures are frequently applied to crops as fertilizer. Unfortunately, crops use and absorb only a small fraction of the nitrogen and phosphorous in these manures ( on average 30%) and the remaining nitrogen and phosphorous runs off into adjacent waterways and ecosystems.
A solution: Use animal manure for microalgal growth
At Demeter, we have developed microalgal growth techniques that use nitrogen and phosphorous in animal wastes from industrial farming operations. These wastes are currently environmental hazards. Our microalgae can remove the nitrogen and phosphorous from these wastes and convert them into useful sugars and fats.
