Where does cellular waste get removed?
Cellular waste is a broad term. The stuff your cells excrete are transported away by different systems. Much of the waste products and useless chemicals end up being filtered out by the kidneys and are then tossed out of the body through urinating. Carbon-dioxide, the waste gas produced by the cellular metabolism, is reabsorbed into the bloodstream and exits through the alveoli in the lungs.
Why does food take so long in the stomach?
Because it needs to stay in the acidic environment of the stomach for 4-6 hours in order to start the digestion of protein.

How do you prevent disease or injury in the digestive system?
The best way to keep your digestive tract healthy is to eat a healthy diet with a lot of fiber. Fiber is found in most fruits and vegetables, as well as in products made with whole grain. Fiber is great for the bowels and keeps them running smoothly. Try to find yogurt with live cultures or probiotics. Probiotics are good for the large intestine.
As for preventing injury to the digestive tract, the best thing you can do is be careful. Chew your food throughly so that the bolus (lump of chewed food) can go down your esophagus smoothly. Avoid eating any foreign objects to prevent any tearing of the intestinal lining.

As backpacker, who has been on trips of several weeks carrying all supplies on the back, I assure you that you excrete little.
This is partly because the food is probably low-residue and carefully chosen, but if you're exercising a lot (as a backpacker does), then your excess is minimized.
On a 21-day trip, our party of 6 went OK (including 7 days snow-caving) on a diet of 24oz per day each. A little less than 700g/day.
[One slightly overweight member, who lost his tobacco during the trip was certain that he'd lost weight, (for his belt was more slack) so on reaching civilization again, his first move was to weigh himself. And was disappointed to find he'd gained weight!. In a 21-day period you can lose fat and put on muscle, which is more dense than fat.]
