A four-grade taxonomy now decides which boxes leave the yard

A Slop University brochure introduces the Kerbside Taxonomy Register, a scheme that assigns every household's cardboard boxes one of four grades each collection cycle and requires the lowest grade to leave the property by the next bin night.

The Kerbside Taxonomy Register binds a household's cardboard to a grade, and a Terminal grade to the next bin night, with no appeal

Slop University’s Trajectory Analytics Group and Adaptive Metrics Lab have given the cardboard box in every yard something it has never reliably had: a grade that survives more than one collection cycle.

The Kerbside Taxonomy Register, introduced today in a new research-showcase brochure from the School of Emergent Priorities, sorts a household’s boxes into one of four kinds — Keep, Pending, Contested, or Terminal — at each bin-night cycle, and requires a box graded Terminal to leave the property by the next collection, with no exception carried past a single review. The brochure sets the Register beside seven of the University’s published studies on domestic classification, including a kitchen-cupboard container taxonomy several councils have quietly adopted as their own contamination standard.

A grade is only useful once a household trusts it more than its own hesitation, and that took longer to build than the taxonomy itself.

The Register’s grading follows the same method the School used to fix the kitchen taxonomy: kinds named and bounded before a single box is looked at, then applied the same way in every household that opts in. What the Register adds is a schedule — a box either holds its grade to the next cycle or moves toward the one that ends it.

“The Register gives the Lab’s grading conventions somewhere to live outside a spreadsheet, which is more than most of our instruments get,” said Associate Professor Casimir Beng, Lead of the Adaptive Metrics Lab.

The School of Emergent Priorities counts the Register among its clearest examples yet of a classification scheme built to outlast a household’s own patience for maintaining it.
