Empty tote recycling in Montgomery County, Maryland

Biotech on the corridor

Maryland Commerce counts more than 300 biotech companies in the county. MilliporeSigma is investing $286 million and moving into a new 250,000 square foot space at the Traville Gateway campus in Rockville. The county had 14,692 manufacturing jobs in 539 establishments in 2024, and more than 130 local and long-distance trucking establishments.

Reagents and buffers move in 275 gallon totes, and they leave empty with an SDS attached. That paperwork is the strongest asset a lab has, because it names the last contents exactly.

The life-sciences labs page sets out how buffer, media, cleaner and solvent totes are graded.

Three corridor cities in one table

The county has 539 manufacturing establishments and more than 130 trucking establishments, so most of what a lab needs to move can move.

The Agricultural Reserve

Created by the County Council in 1980, the Reserve covers 93,000 acres, about a third of the county, and helps retain more than 500 farms. It is the buy side of this site: farms look for clean totes for stock water and irrigation. The food-grade history page explains what paperwork a tote needs for that work.

A tote that held a laboratory reagent does not go to a farm. A tote that held a food-grade ingredient and has the record to prove it can.

The Maryland rulebook

Maryland’s hazardous waste rules are in COMAR 26.13 and are enforced by MDE. The state does not recognize the federal very-small-quantity generator category and uses Maryland-defined small quantity and fully regulated generators instead. A Montgomery County lab should read its category from MDE, not from a federal chart.

The empty-container test is the federal one in 40 CFR 261.7. See the three rulebooks for how it sits beside DOEE and DEQ. Sites in 20850, 20878 and 20874 and the county’s other postal codes use the same form.

What to send from a lab

Send the SDS for the last product, the tote size and count, and the heel from the Empty Check. A laboratory that keeps batch records can add the lot, which turns a used tote into a traceable one. A line about whether the product is classed as acute saves a round of questions.

Manufacturing by the numbers

The county’s 14,692 manufacturing jobs in 539 establishments work out to about 27 jobs per establishment. Most are small plants and laboratories, not large factories, which is why a request from the county often lists a few totes of one product rather than a trailer load.

That also explains the paperwork. A small lab with one reagent supplier can usually name the last contents in one line, and the SDS for it is a single page.

Where the labs and the farms meet

The I-270 corridor holds the biotech employers and the Agricultural Reserve holds the farmland, within the same county lines. The two sides use totes in opposite ways: a lab tote is a one-way package for a controlled product, and a farm tote is a long-lived water or feed vessel.

The food-grade history page explains why a lab’s reagent tote never moves to the farm side, however clean it looks.

How the county and the corridor connect

Rockville sits at the south end of the biotech corridor, Gaithersburg in the middle and Germantown at the north, with I-270 running through all three. A lab in any of them can describe its site by the nearest exit, which helps a hauler plan a visit.

Reagents, buffers and media

A buffer is a solution that holds its acidity steady, a medium feeds cells in culture, and a reagent drives a chemical reaction. They arrive in different strengths, and a laboratory may buy all three in totes. Label each correctly in the request. A medium tote that held nutrients and water is far easier to place than a reagent tote that held a corrosive, and the grade follows from that alone.

Small counts, careful records

Laboratories keep lot numbers, certificates and batch notes as a matter of routine. Quote the lot number of the last product in a request, since it ties the tote to a supplier record that no label can match.

A lab that retires several totes at once after a project ends can send one tally with a row per reagent, listing size, count, heel and storage location.
