Copper chloride, hydrogen peroxide, and the reality that some processes can't be made green—only less bad

Moving beyond standard processing to examine lith printing—where extreme dilution creates an unexpectedly favourable environmental story

Comparing RA-4 colour printing with scanning and digital output—which is actually more sustainable?

Colour negative processing adds real environmental concerns beyond black-and-white—but silver remains the dominant issue

Practical interventions ranked by actual environmental impact—silver recovery, water efficiency, and the hierarchy of what actually matters

Why the developer-versus-developer debate misses the point entirely—fixer contains silver at concentrations millions of times higher than lethal thresholds for aquatic life

Examining the environmental claims around coffee, wine, and plant-based film developers—what the chemistry says, what the toxicology shows, and why the conversation might be missing the point
