A central thesis of our business is that reuse beats recycling, and recycling beats virgin manufacture, for almost every measurable impact. The numbers come from public lifecycle assessments and our own internal cradle-to-gate data. Here’s the full math for one 275-gallon composite IBC.
Virgin manufacture
Industry LCA data for new composite IBCs converges on ~52 kg CO2-eq per unit for the HDPE bottle and ~18 kg CO2-eq for the galvanized steel cage. The pallet adds another 5–8 kg for wood, more for steel or plastic. Total: roughly 62–78 kg CO2-eq for a new composite IBC delivered to a Midwest customer, depending on pallet choice and transportation distance.
Reconditioning
Our internal data for a Grade B reconditioning cycle: 4.2 kg CO2-eq from wash bay energy and chemistry, 1.8 kg from pickup transportation (averaged over our typical 75-mile pickup radius), and 1.4 kg from delivery transportation. Total: ~7.4 kg CO2-eq per cycle. Including amortized facility energy and pallet/cage component replacement, total comes to roughly 8.5 kg per cycle.
Recycling
End-of-life recycling of the HDPE bottle as feedstock to other plastic products: ~12 kg CO2-eq per bottle for grinding, washing, and pelletizing. The recovered material displaces ~38 kg of virgin HDPE production. Net: about 26 kg of avoided CO2-eq, plus the carbon cost of the recycling.
The cycle math
One bottle in our reuse stream, averaging 11 deployments before recycling, has a carbon footprint of roughly:
- Virgin manufacture (amortized over 11 cycles): 62 kg ÷ 11 = 5.6 kg/cycle
- Reconditioning (per cycle): 8.5 kg
- End-of-life recycling (amortized): 12 kg ÷ 11 = 1.1 kg/cycle
- Total per deployment: ~15.2 kg CO2-eq
vs. single-use new tote: 62 kg per deployment.
Net savings: roughly 47 kg CO2-eq per deployment when comparing reused vs. single-use new.
Where the math breaks
Long-haul transportation erodes the benefit. A used tote shipped 1,200 miles from a coastal recycler to a Midwest end user adds about 24 kg CO2-eq in transportation alone, which would consume most of the deployment-level savings. The case for local reuse is much stronger than for cross-country reuse. We won’t ship empties more than ~500 miles for this exact reason — the carbon story stops adding up.
Water
Our recycled wash bay (covered separately) uses about 50 gallons of fresh water per reconditioning cycle, vs. an industry-typical 110–140 gallons. Over a fleet’s lifecycle this is meaningful but smaller in carbon-equivalent terms than the energy story.
