A Systematic Approachto Hazardous Waste Managementfor Very Small Quantity Generators

This is the authors' abstract. We don't add key points for this paper.

Hazardous waste (HW) management remains a significant environmental and regulatory challenge, particularly for very small quantity generators (VSQGs), which often lack the technical resources and institutional infrastructure available to larger facilities. Despite generating relatively small volumes of hazardous waste, VSQGs contribute disproportionately to regulatory violations. Recent enforcement data indicate that approximately 46% of hazardous waste violations are associated with small generators (VSQGs and SQGs). When normalized by waste volume, violation rates are markedly higher for VSQGs (∼18.7 violations per thousand metric tons) compared to ∼2.2 for SQGs and ∼0.1 for large quantity generators (LQGs). These data indicate that most violations among VSQGs arise from fundamental compliance deficiencies, particularly in waste identification, container management, and labeling, highlighting systemic gaps in training and program implementation. This work presents a systematic framework integrating waste identification, on-site handling, transportation, disposal, and minimization, with emphasis on regulatory thresholds, including acute hazardous waste and universal waste requirements, to support improved compliance and reduced environmental risk.
