The idea of environmentally friendly, non-food wasting burgers sounds good but I'm not sure if it's possible. Meat is so phenomenally resource intensive[0][1] that reducing waste at the restaurant to zero still leaves you with a pound of beef that required up to 1,800 gallons of water to make. That number gets smaller if the animal eats wild grass or what would otherwise be waste products but a cow is a an inefficient way of getting nutrients to your plate.<p>Livestock in general eat large amounts of corn and oats, and with their feed conversion ratios[3] that's a 40-95% food loss of food humans are perfectly capable of eating.<p>[0] - <a href="http://www.huffingtonpost.com/2014/10/13/food-water-footprint_n_5952862.html" rel="nofollow">http://www.huffingtonpost.com/2014/10/13/food-water-footprin...</a>
