IBC Denver wasn’t founded to make money first and feel good about it second. It was founded because nobody else was bothering to wash out perfectly good tanks, and somebody had to.
Same form on every page. Same human inbox. We answer every inquiry — promise.
A new IBC tote takes around 32 kilograms of CO₂, 45 gallons of crude oil equivalent, and a tidy chunk of cage steel to manufacture. After one trip across the country, most of them get tossed into a chain-link junkyard somewhere off I-10 and forgotten.
That always seemed insane to us. So we built a company whose entire job is to keep that from happening — and to make it cheaper than buying new while we’re at it.
Today, an IBC Denver tote moves through an average of 3.4 lives before it’s finally too tired to refill. When it gets there, the bottle is granulated into HDPE pellet and the cage is baled for the steel mill — both back into manufacturing within 90 days.

0 lbs to landfill ✓The complete IBC Denver origin story, year by year, including the parts where we made mistakes that other tote companies are still making.
Founder Aldo Ramírez bought four empty IBC totes off a beverage co-packer, washed them in his driveway, and resold them on Craigslist for $40 each. Within six months he had a small lot, a leaky pressure washer, and a mailing list.
A 4,000 sq ft warehouse, one second-hand Hotsy hot-wash skid, and a hand-painted sign reading “REBORN TANK CO.” The first commercial buy-back contract was signed with a Denver-area glycerin distributor.
After three months of phone-tag with sales reps, we deliberately took the phone number off our business cards. Email-only became a feature, not a bug — turns out customers love a written paper trail.
We started arranging full-truckload pickups in Texas, California, Oregon, and the Dakotas. The diverted-from-landfill counter rolled past 5,000 totes for the first time.
After a year of validation work, our Denver reconditioning lines earned the documentation needed to sell into food-grade applications. Honey, syrup and concentrate buyers showed up almost overnight.
We dropped “Reborn Tank Co.” from the storefront and went all-in on the IBC Denver name — because the Front Range industrial corridor was already where the bulk of our reborn totes were rolling off trailers, and the city deserved its own tote yard.
A dedicated bay for cutting tops, welding nipples, fitting sight gauges, swapping valves. People started bringing us totes to convert into rain barrels, micro greenhouses, and aquaponics systems.
We partnered with a local plastics processor so that totes too tired to live another life are stripped, granulated and reborn as pellet — and the cages get baled for steel mills. Zero landfill, in writing.
Crossed 14,000 reborn totes and 3.9 million pounds of HDPE diverted from landfill. The original 2008 driveway is now a private museum the team visits twice a year.
Every tote that ships from our yard comes with a one-page Birth Certificate: prior contents (when known), grade, hot-wash log, leak-test result, and the name of the human who finished the inspection. We keep our copy on file for seven years.
PRIOR LIFE : Soybean oil WASH : 165°F caustic INSPECTION : Pass — no scuffs CAGE : Galv. — 2018 PALLET : Hardwood OK GRADE : Food-rinsed B INSPECTOR : Marisol G. EXPECTED LIFE REMAINING : 8–11 yrs NEXT LIFE : Maple syrup ✓
Reconditioning bays, the team, and the beat-up office cat all live a few blocks from the South Platte in southwest Denver — exactly where the “Denver” in our name says we should be.

We don’t have a phone number. We answer every email by hand, usually inside one business day. If you’d rather drop by the yard, swing on past — there’s usually coffee and almost always a forklift backing up.
The whole staff fits around a single conference table. Here is who you are emailing when you write to hello@ibcdenver.com.
Started the company in 2008 by washing four IBC totes in his driveway. Still personally answers customer email on Saturday mornings. Fluent in English, Spanish, and butterfly-valve diagnostics. Will not return your phone call because he does not have one.
Runs the reconditioning bay and signs the Birth Certificates that ship with every reborn tote. Has personally inspected over nine thousand IBCs. Was a chemistry teacher in another life and still occasionally lectures the bay staff about the difference between sodium hypochlorite and chlorine bleach.
Five years in the bay, the longest-tenured non-founder employee. Knows things about IBCs that nobody else in the building knows. Maintains the hot-wash skid the way some people maintain a vintage motorcycle.
Drives one of our two buy-back trucks. His weekly route hits twelve to twenty pickups across the Front Range and the Western Slope. Has been on more impromptu plant tours than anybody we know.
Joined in 2022 to take over the customer inbox so Aldo could spend more time on the yard. Replies to most quote requests within forty minutes. Has a graduate degree in environmental policy and is overqualified for this job in the most useful possible way.
Showed up at the warehouse as a kitten in 2019 and stayed. Spends most of her day asleep on top of the inspection table. Considered, at this point, a permanent fixture of the operation. Will accept tribute in the form of carnitas.
The figures we keep coming back to when we stop and look at what the company has actually done.
Three things we are working on right now that we are not in a hurry about, but which we believe will define the next decade.
We use about 18 gallons of city water and a small amount of natural gas to recondition every tote. We are evaluating an electric hot-wash system that would let us run the entire bay on electricity, and we are looking into greywater capture for the rinse cycles. Both projects are on a slow track because we want to get them right rather than fast.
The economics of buy-back are heavily freight-driven. A second yard somewhere in the Pacific Northwest or the Southwest would let us shorten freight legs for half our pickups. We are not in a hurry — opening a second location is the kind of thing that breaks small companies — but it is on the long-range plan.
The Reborn Wall — our gallery of unusual things customers have built from old totes — has become one of our favorite parts of the website. We want to turn it into a small print zine we ship to customers and post around the yard. We are looking for a designer who would like to collaborate on it.
We are not getting a phone number. We are not opening a Slack. We are not building a chatbot. We are not adding live chat. The customers who have stayed with us for ten years stayed because of what we are, not in spite of it, and we are not going to dilute it.
Every honest company history is mostly a list of mistakes that became lessons. Here are six that meaningfully shaped how we operate today, in roughly chronological order.
In our first year, we sold a batch of six rinsed-but-not-hot-washed totes to a small honey packer who refilled them with raw honey. The honey developed an off flavor. The customer came back politely but firmly to tell us about it. We refunded the order, replaced the totes with properly hot-washed stock at our cost, and changed our process so that no tote ever ships as "clean enough" again. Every reconditioned tote now goes through the full nine-stage cycle, no exceptions, no shortcuts.
We signed a route contract with a regional broker that paid us per delivered tote at a rate that turned out to be lower than our actual cost per delivered tote once fuel surcharges were factored in. We honored the contract for the full six months and lost roughly four thousand dollars on it. The lesson: never quote a freight rate without baking in fuel surcharge and seasonal variability. Our quotes today have been profitable on every leg since 2012.
We launched a monthly customer newsletter on a Mailchimp-style platform. The goal was to keep customers in the loop about new inventory and seasonal pricing. The unsubscribe rate was over 40% within three months and the time we spent assembling each newsletter was time we could not spend on customer email. We killed the newsletter at the end of 2014. We have not run one since.
We paid a third-party auditor to certify our hot-wash process under a specific food-safety standard. The certification cost about $4,800 and gave us a pretty seal we could put on our shipping documents. We discovered that almost no customer cared about that specific seal — they wanted the wash log and the Birth Certificate, both of which we already provided. The seal expired in 2019 and we did not renew. We use the same money on better wash chemistry instead.
We hired a sales representative to grow the business during the slow stretch in spring 2020. They were a fine person and a competent salesperson. The mismatch was that our customer base does not respond to sales outreach — they respond to honest documentation and patient email. The salesperson spent six months making calls that did not convert and we parted ways amicably. We have not hired a sales role since. Our growth comes from customers who find us, read the site, and write to us.
We had an opportunity to take over a second warehouse in Salt Lake City to expand our reconditioning footprint into Utah. The space was right, the price was right, the timing seemed right. We talked about it for two months and ultimately decided not to move forward. The reason was honest: opening a second location is the kind of decision that breaks small companies that are not ready, and we were not ready. We are still glad we passed. We may revisit the same idea in 2027 with more cash on hand and a bench of bay leads who could open a second location without us being there every day.
And the small handful of decisions that shaped the company in ways we are happy about.
The single most company-defining decision we have made. Eleven years later it is still the choice that current customers cite most often when explaining why they prefer working with us. We will never reverse it.
The $40 phone holder we bolted to the wall in 2018 has paid for itself many thousand times over. The practice has eliminated almost all post-shipment disputes and given us an operational visibility that we did not know we were missing.
The mods bay started as a side project and turned into a steady stream of customer relationships, customer photos, and a small but reliable revenue line that funds the rest of the operation. It is also where most of the most interesting projects have come from in the last few years.
The decision to commit, in writing, to zero pounds of material to landfill — and to issue Certificates of Recycling for every tote — was the moment when our sustainability story stopped being a marketing point and started being a competitive moat. Customers who care about closed-loop reuse cannot get the same documentation from anyone else in our region.
The decision to publish our carbon calculation methodology in full on the eco-impact page was unusual for a company our size. Several customers and at least one industry observer have told us it is the most transparent sustainability claim they have read in our industry. We did it because we wanted to be defensible in front of any auditor, and the side effect has been a lot of trust.
About 78% of our customers in any given year are repeat customers — people who have bought from us before and are buying again. Most companies do not break out their repeat-customer percentage publicly because it tends to be a smaller number than they would like it to be. Ours has been climbing roughly two percentage points per year since 2018, which we are quietly proud of.
When we ask our repeat customers why they keep coming back, the answers cluster into four themes. We have heard variations on these so many times that we keep them in mind whenever we are making operational decisions.
Customers value the predictability of our grading system, the consistency of our wash cycle, and the reliability of the documentation that ships with every tote. They never get a surprise. They know the Grade A tote in this order will look like the Grade A tote in the previous order. The consistency is a feature.
Customers know that the price on our quote will be the price on the invoice. They have been burned by other vendors who add fuel surcharges, environmental fees, regulatory fees, and last-minute "small order" charges. We do none of this. The boring honest pricing is the kind they remember next time.
The customers who initially worried about the no-phone policy almost always tell us, after the first transaction, that they prefer it. They get faster replies, written records they can forward to their team, and zero hold music. Email-only is the policy that converts skeptics into evangelists.
For customers in larger organizations, the documentation we provide makes it easy to justify the purchase to internal stakeholders. The wash logs, photographs, Birth Certificates, and Certificates of Recycling are exactly the kind of artifact that procurement audits ask for. Our customers do not have to fight for the purchase because we have already done the homework for them.
We are not for everybody, and the customers who have left us tell us so for predictable reasons. Sharing them honestly because the type of customer we are not a good fit for is also useful information.
