Wilmington DE Dumpster Rental Case Study: LEED Waste Diversion on a Commercial Renovation

Three Weeks, Nearly 100 Tons, None of It Landfilled

In May 2026, a contractor running a large commercial renovation in downtown Wilmington needed more than a dumpster. The project was pursuing the LEED v4 Construction and Demolition Waste Management credit, so every ton leaving the building had to be separated by material, weighed, and documented. They called WRS for dumpster rental in Wilmington, DE and our LEED reporting.

Over three weeks of reporting, the job produced 99.2 tons of material. All of it was recycled. Not one load went to a landfill.

Working Around a Shared Loading Dock

The tonnage was the easy part to plan for. The building made everything else harder. It was a multi tenant property in the middle of the city, and the crew was demolishing while other businesses stayed open around them.

• One loading dock, one lane, several tenants. Every container drop and pickup had to fit around the other businesses using the same dock.
• Tight corridors inside. There wasn't much room to work with, so containers had to be placed precisely.
• Rush hour traffic. Downtown streets back up in the morning and late afternoon, which is exactly when a job like this wants service.
• Debris all day long. The schedule kept crews tearing out material from start to finish, so it never stopped piling up.

How We Kept the Building Clear

We set a daily rhythm with the site supervisors and stuck to it. Containers were staged early in the morning before the crews showed up. Full ones were pulled late in the afternoon to clear out what the busiest hours produced. When demolition surged in the middle of the day, we ran extra swaps instead of making the crew wait.

Dispatch and the site supervisors stayed in touch in real time the whole way through. That's what kept debris from building up inside, and it mattered for more than housekeeping. Loads that sit around and get mixed together are hard to keep separated, and separation is the whole point on a LEED job.

We didn't miss a single service window, and the dock kept working for the other tenants the entire time.

Week by Week Tonnage

Metal made up most of the job, which is typical when a commercial interior gets gutted down to the structure. For the mixed loads, each ticket recorded how the material split. In week 3 that came out to 75% wood and 25% plastic.

What the LEED Paperwork Looked Like

On a LEED project, the hauling is only half the job. The other half is proving where everything went. For every haul, the contractor got:

• The material stream it belonged to: metal, wood or plastic
• The weight of that load
• The material percentages for any mixed load
• A summary for each reporting period with total tons diverted

The credit asks for at least 50% diversion. This project hit 100% in every reporting period, and the documentation was ready to go into the certification submission.

The Result

Three weeks, 99.2 tons, and nothing landfilled, all on a shared dock in one of the busiest parts of Wilmington. The renovation kept moving, the other tenants kept working, and the contractor walked away with the records they needed for the credit.
