Lesson-specific diagram for Chemical processes in local communities and industries. It visualizes the reasoning sequence tied to $\text{inputs}\to\text{transformations}\to\text{products/wastes}$. Text alternative: A chemical-process analysis should trace matter, energy, useful products, wastes, exposures, and local consequences rather than naming an industry alone. Choose a representation that matches the chemical scale and evidence; do not infer more precision or mechanism than the data support.
