Biogas: Alternative Energy at Work

working with pig manure you work with a 1:1 ratio, or rather, 5 gallons of water for the same 5 gallons of manure. In Costa Rica they use twice as much water for the cow manure because the cattle grazes on grasses, making the manure more fibrous than that of pigs. So, keep in mind that grain-fed cattle may produce less-fibrous and easily-digested manure.
