The first software built for household hazardous waste collection events.
You're managing 10-20 HAZWOPER staff, 100+ hazardous waste types, EPA e-manifests, supply trucks, forklifts, and a billing method that changes per client — for events that happen every weekend across multiple counties.
Spreadsheets can't run HHW events at this scale. This software can.
We know what your HHW event week looks like.
Monday
Pulling together the pre-op report for Saturday’s HHW event. Which site? How many HAZWOPER staff? Which billing method — per car or Chemsweep?
Tuesday
Calling staff. You need 15 HAZWOPER-certified techs who can drive to the site. You call 40 people to get 15 confirmations. Three will cancel Friday night.
Wednesday
Supply list. How many 55-gallon drums? How many Gaylords? Did someone order the CYBs? Where’s the forklift coming from?
Thursday
EPA manifests. Building hazardous waste manifests in Word or pulling up blank forms, filling in RCRA waste codes by hand. Again.
Friday
Dispatch orders. Who’s going where? What time? What equipment? You email a Word doc and hope everyone reads it.
Saturday
The HHW collection event. Something was missed. It always is.
Sunday
Building the invoice. In Excel. By hand. For the third time this month.
What if all of that was already done before Monday?

The Chemsweep Advantage
If you run Chemsweep household hazardous waste events, you know the billing is unlike anything else in the industry. Annual allotments. AG Summary reports. Tracking what's been used and what's remaining.
Every Chemsweep HHW operator we've talked to is doing this in Excel. We built Chemsweep billing software from the ground up because we sat next to the people who run these programs.
The PaintCare Advantage
PaintCare paint collection has program-specific rules, separate invoicing, and documentation requirements that generic billing software can't touch.
We built PaintCare collection software with the exact invoicing and reporting structure these programs require.

HHW Collection Events — Frequently Asked Questions
A household hazardous waste (HHW) collection event is a temporary site where residents can drop off hazardous materials from their homes — paint, oil, solvents, batteries, electronics, pesticides, etc. HHW events are typically run by municipalities or solid waste districts on weekends. They require EPA compliance, HAZWOPER-certified staff, manifesting, and complex billing methods.
Mercovi supports per-car flat rate, per-vehicle weight, per-item, Chemsweep (national rebate program for pesticide waste disposal), PaintCare (state paint take-back programs), hazard surcharges, and custom tiered pricing. Different events and clients use different billing — Mercovi automatically handles all of them.
You create the event, specify how many HAZWOPER staff you need, and Mercovi shows qualified staff filtered by certification type, distance from the event site, and past availability. Send SMS invitations — staff confirm directly from their phones. No calling 40 people to get 15 confirmations.
Yes. Mercovi integrates Chemsweep rebate tracking and PaintCare program billing. When items are logged during an event, you select the program, and Mercovi manages state rebates and invoicing automatically.
Yes. For any hazardous waste leaving the event site, Mercovi generates EPA e-manifests with all required RCRA waste codes, generator info, transporter details, and destination facility info. Submit electronically to RCRAInfo — all records stay audit-ready.
Mercovi alerts you immediately. You can reassign staff from your qualified pool with one click, or reschedule the event. No more cascading spreadsheet chaos when someone calls in sick.
