The document discusses the processes of composition, decomposition, and recomposition as they relate to recycling and composting. It defines composition, decomposition, and their building block roles. Decomposition breaks down large organic materials into simpler molecules over time frames from weeks to millions of years. Proper decomposition is important to prevent piles of waste from accumulating. The document promotes recycling and composting to speed decomposition and reuse materials, calling them the "non-military cavalry" that can break down complex structures with help from microorganisms, earthworms, water, and other factors.
