Start collecting old car batteries...
For real though the guys I knew who were hunting and skinnin would usually eat a good deal of the meat, compost the blood with straw or hay, and probably the guts and brains and that stuff too if it wasn't left out in the woods.
I think in this guys case he should take it to have it done, and I wouldn't eat the meat or dog food it. I usually compost what the cat's drag in and don't finnish eating.
