How We Actually Decide What to Pay for Your Empties

A buyer asked us to walk them through the math behind our buy-back offers. Here it is, unredacted.

We get asked about our offer prices roughly twice a week. Most of the time the question is "why are you offering me $X and the recycler down the street is offering me Y?" Here's the math we use.

The four inputs

Our per-tank offer is a function of four things:

  1. Tank size and condition (drives our resale value once washed)
  2. Distance to your facility (drives our freight cost to pick up)
  3. Volume at your site (drives consolidation efficiency)
  4. Time elapsed since the prior fill (drives wash chemistry needed)

How each input moves the offer

A clean 275-gallon HDPE tote with an intact valve, prior food-contact fill, drained within 90 days, sitting on a site where we can pick up 20+ tanks: we'll pay the top of our range, around $65 per tank.

The same tank with a missing valve drops the offer by roughly $15.

The same tank in a site where we can only pick up 4 totes drops the offer by another $10 because the per-tank freight cost goes up sharply.

The same tank where the prior fill is "we're not sure, but probably industrial soap" drops it another $5 because we need to run a more aggressive wash cycle.

Why our offers beat single-tote recyclers

A single-tote recycler is monetizing only the HDPE scrap value, which is roughly $0.18/lb. A 275-gallon tank yields roughly 144 lb of HDPE scrap, so the raw scrap math gives them roughly $26 per tank. After their handling and freight cost, they're often paying $5–$15 per tank or charging you to take them.

We're monetizing the tank as a tank. Our resale path on a reconditioned 275 is $89–$185 retail. After our wash labor, gasket replacement, freight, and yard overhead, we have roughly $35–$50 of margin per tank. That's why our buy-back offer can be substantially higher than a recycler's: we get more value out of the same input.

Why we sometimes can't beat the local market

Two cases:

  • You're more than 4 hours from our yard and we can't consolidate the run. Freight eats our margin.
  • The tank has a structural issue we can't undo. We're paying you for fab stock at that point, which is roughly $5–$15.

The fair-deal note

When the math doesn't work for us, we'll tell you and route you to a partner. We'd rather lose a single transaction than damage trust by lowballing.

Our offer is roughly 1.5x to 3x what a local recycler will offer for clean tanks. It's not magic — it's just that we're monetizing a tank-shaped object, not 144 lb of HDPE pellets.
