You're talking about the 0.0001% of things it doesn't recycle. But almost every single molecule of your body will be recycled in dozens of different ways by hundreds and thousands of hungry little mouths that specialize in recycling viable organic matter--even your bones. Effectively everything within ~10cm of the surface of the Earth is going to get recycled into usable matter for the biosphere, and even those things ~1m will slowly decay in rich soil. Soil is alive by the way. It's not dead dirt, but 50% by volume bacteria, fungus, and other micro-organisms. Sure, soil accumulates and packs down and sediments out, as evidenced by so many geologic layers, but that's the 0.0001% I was referring to--limestone, sandstone, peet, shale, oil--the leftover of the very active recycling system back that pumps matter back into the biosphere and extracts latent chemical energy from it. Think of it; a layer in the sedimentary record that represents 10,000 years might only be 1cm thick, globally. That's not much waste. And it roughly balances out from all the volcanic eruptions, asteroids, meteorites, and space dust the Earth sweeps up.
