Medical Waste Generator Categories: VSQG, SQG & LQG
How much regulated waste you generate each month puts you in a “generator category” — and that category drives your pickup frequency, storage limits, and paperwork. Here’s what VSQG, SQG, and LQG mean for your facility.
In this guide
The three generator categories
| Category | Monthly volume | What it means |
|---|---|---|
| VSQG | < 220 lbs | Flexible storage, less frequent pickups, simpler records |
| SQG | 220–2,200 lbs | Manifests, regular pickups, secure storage |
| LQG | > 2,200 lbs | Strict timelines, staff training, detailed tracking |
Why your category matters
- Sets how often you need pickups
- Caps how long you can store waste on-site
- Determines your documentation and training obligations
- Affects your cost structure
Getting sized right
Most physician offices, dental practices, and clinics are VSQGs — which makes mail-back a great fit. Higher-volume sites move up to SQG/LQG and scheduled pickup. We size your sharps and RMW program to your category so you’re compliant without overpaying.

Mail-back for VSQGs, scheduled pickup for SQG/LQG — compliant, right-sized, and documented, with no contract.
Frequently asked questions
What are the medical waste generator categories?
VSQG (very small quantity generator, under 220 lbs/month), SQG (220–2,200 lbs), and LQG (over 2,200 lbs) — based on how much regulated waste you generate monthly.
How do I know my generator category?
Estimate your monthly regulated-waste weight. Under 220 lbs is VSQG; 220–2,200 is SQG; over 2,200 is LQG. Most small clinics are VSQGs.
Does my generator category affect how I dispose of waste?
Yes — it sets pickup frequency, on-site storage time limits, documentation, and training requirements. VSQGs have the most flexibility and often use mail-back.
Can a small office use mail-back?
Yes — VSQG-level volume is ideal for prepaid mail-back kits with no contract.
