For an internal carbon-tracking project last year we picked one tote at random from our long-term records and traced its history from its first life to its current one. The unit left a chemical sanitizer distributor in late 2018, originally heading to a dairy operation south of Sedalia. Six years later it is on its third reconditioning and its fourth distinct industry. Tracing the path is a useful exercise in what a properly-handled tote can actually do over a useful life.
2018: original food-side service
The tote shipped in October 2018 filled with a food-contact-approved dairy line sanitizer. It arrived at the dairy, was emptied over the following six weeks, and sat empty in the yard until a regional pickup in March 2019. Original carbon footprint for the tote at this point is roughly 420 lb CO2e — the new-build number we discussed in an earlier post.
2019: first reconditioning, into irrigation
Inbound to a reconditioner near Marshall, MO. Triple-rinse with caustic wash, light cage straightening, original valve retained after pressure test. Resold to a row-crop operation outside Marshall as part of a 12-unit irrigation cart. Served there for two seasons. Reconditioning footprint at this stage: about 45 lb CO2e. Cumulative service: roughly 18 months active use plus 4 months storage.
2021: second life, into ag chemical mixing
In late 2021 the irrigation operation downsized and the cart was sold to a custom-applicator service. The tote ran ag chemical mix water for two more seasons, mostly clean water and dilute fertilizer concentrate. Routine inspection at end of 2023 found a slow weep at the original valve — replaced in field, no other issues.
2024: second reconditioning, into rainwater
Inbound to our facility in spring 2024 from the custom applicator, who was retiring the cart. Standard reconditioning, new valve, light cage repair, painted exterior on customer request. Resold to a homestead build outside Tipton, MO as part of a four-tote rainwater array. Currently in service. Cumulative service since 2018: roughly 60 months active use, three distinct industries, four owners.
- 2018: dairy sanitizer, original ship
- 2019 to 2021: row-crop irrigation
- 2021 to 2023: ag chemical mixing
- 2024 to current: residential rainwater
- Cumulative reconditioning footprint: about 90 lb CO2e across two cycles
- Versus three separate new totes for the same span: about 1,260 lb CO2e avoided
What this lifecycle says about the model
One tote, properly handled and reconditioned twice, has done work that would otherwise have required three new totes. The carbon avoided is roughly 1,260 lb CO2e — call it a one-way drive from Columbia to Houston. The same physical bottle is still in service and will probably go through one more reconditioning cycle before the HDPE finally goes to the grind line. That is what reuse at this format looks like when the chain of custody and the reconditioning quality both hold up over time.
The most environmentally valuable tote in our yard is the one that has already been reconditioned twice. Every additional cycle multiplies the original embodied carbon across more service-years.
