Trash Optimizer Dataset

Assembled waste classification dataset covering 18 categories, used to train the cpoisson/trash-optimizer-models series.

Built with a custom pipeline that normalises, filters and balances images from three sources:

Source	Categories contributed	License
RealWaste (UCI / Kaggle)	cardboard, food_organics, glass, metal, miscellaneous_trash, paper, plastic, textile_trash, vegetation	CC BY 4.0
RHWC (Kaggle)	cardboard, food_organics, glass, metal, paper, plastic, textile_trash	CC BY-SA 4.0
Custom (web-scraped)	battery, car_battery, light_bulb, mirror, neon, pharmacy, printer_cartridge, tire, wood	⚠️ Mixed — images sourced from the public web, licenses vary

Note: The custom category images were collected from publicly accessible web sources. Their individual licenses may vary. Use for research and non-commercial purposes.
