In ancient Riga, like many other cities, a dense population led to significant environmental impacts, particularly concerning waste disposal. The Rīdziņa River, once a vital waterway, transformed into a dumping ground, showcasing the negligence and challenges of waste management through the ages. Historical documents reveal repeated warnings against littering the river, streets, and city walls, indicating that despite these prohibitions, the citizens frequently disregarded them.

Archaeological excavations have uncovered ample evidence that people historically disposed of their waste carelessly. Findings show that the Rīdziņa River became severely polluted over time, leading to its burial in an effort to mitigate the trash pile-up. This situation highlights the struggle of Riga's inhabitants to address waste management, as they attempted various solutions to combat the accumulation of trash while still facing the pressing need for daily sanitation.

The discussion by archaeologist Reinfelde also emphasizes that waste management was a concerned issue in the city's regulations, albeit often ignored by its citizens. The investigations into these ancient practices reveal that even then, urban waste issues provoked attempts at enforcement and societal responsibility, making it clear that the practice of waste disposal has evolved significantly, yet many challenges remain consistent today.
