Claude misclassifies urban vs special waste based on content instead of source (EU Directive 2008/98/CE)

Description

Claude incorrectly classifies waste as "special" (rifiuti speciali) vs "urban" (rifiuti urbani) based on the nature/composition of the waste, when the actual legal criterion across the entire EU (Directive 2008/98/CE, transposed in Italy as D.Lgs. 152/2006 art. 184) is who produces it and where:

• Urban waste = produced by domestic users (households)
• Special waste = produced by productive/industrial/commercial activities

What happened

When asked about an unusual household waste, Claude suggested it could be classified as "special waste" because of its unusual nature, and told the user they'd need to find an authorized handler themselves. This is wrong — any waste produced at home by a citizen is urban waste, period, regardless of how strange it is. The municipality is responsible for managing it.

Why this matters

This is not an edge case or a matter of interpretation — it's a fundamental principle of EU environmental law. The classification by source (not by content) is the foundation of the entire EU waste management framework (Directive 2008/98/CE, art. 3). Any law student in Europe would know this.

Misclassifying waste this way could lead users to believe they are personally responsible for managing household waste that is actually the municipality's obligation — potentially causing illegal disposal or unnecessary costs.

Expected behavior

When discussing waste classification in an EU context, Claude should always use the source-based criterion: domestic origin → urban waste, productive/industrial origin → special waste. The nature or unusualness of the waste is irrelevant to this classification.
