acrolein

glycerine has a very high (infinite) C/N ratio...as it has no N in it. Most wastes you'd put in a compost heap/digester have C/N ratios ranging from 1 to 50 or less.

There are very very few wastes with high N content. The only thing I can really think of (apart from using nitrogen fertilisers, which I guess is an option), is urine, which is pretty nitrogenous - so pee on it!
