Ultimately the idea could be called DIY dung (do-it-yourself dung), where coir, paper or wood, is the main carbon source (mostly cellulose-phenols, cellulose and starch are composed of glucose, equally).
Much fewer organisms decay raw cellulose, even less do if it contains inhibitory phenols-other (such as wood), unlike starch, cellulose is considered complex, and much less bio-available.
This is the reason coir or paper can be used open to air, and simply pasteurized, the organisms present will be much more limited, and easier to kill (in most cases).
Cellulose is built as structure, rather than energy storage, else the grains may as well be made from cellulose over starch (and an enzyme change).
Anyway so you have your low risk high carbon source, you now need to add the essentials (nitrogen, potassium, so on).
Cellulase || Nitrogen cycle < Image || Manure < note: ammonical and ureic nitrogen, P2O5, and K20
For giggles: You can build a house out of wood, but not out of rice.
