A brief survey of non-silver processes and their environmental profiles—from genuinely sustainable to surprisingly problematic

Consolidating nine posts of research into a practical decision framework for darkroom sustainability

A process that produces stunning metallic colours—and some of the nastiest waste I've seen in a darkroom

Film washing is solved. Print washing is where the water goes—and where the biggest sustainability gains remain

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
