Recyclable one-way kegs for beverage producers who ship draught beyond their own region. Fills on your line, pours on standard draught equipment and is recycled where it is emptied.
A stainless steel keg only pays off when it comes back. On export and low-rotation routes it travels back empty, gets cleaned and refilled, and ties up capital for months. Sometimes it never comes back at all.
A Dolium keg ships one way, pours through your existing draught equipment and is recycled locally. The lower a keg rotates, the more that makes sense. On high-rotation routes stainless steel stays the better choice, so we are complementary to stainless steel kegs, not a replacement.
Increase your draught profitability by using the right combination of Dolium with your stainless steel park. Do not hesitate to contact us to help you find the right solution for each case.
Start with when a one-way keg pays off. Already buying them from someone else? Go straight to what makes a Dolium different.
Three steps, and none of them is a return trip.
Fills on your existing filling equipment at the same speed as stainless steel. No re-tooling, no special filling heads.
Pours through standard A, G, S and D spears. The patented APRV (Automatic Pressure Relief Valve) keeps the pressure safe over the whole trip.
The empty keg goes into the local recycling stream. Nothing is collected, nothing is cleaned, nothing travels back.
Draught is no longer just beer. The same keg, the same draught equipment and the same no-return economics carry every product family, each with its own reason to be on tap.
The question is no longer whether a one-way keg makes sense, but which one. This is where Dolium differs from another one-way keg, not from stainless steel.
A re-closable pressure relief valve, unique among one-way kegs. Opens at 5 bar, re-closes at 2 bar and can be released by hand to depressurise the keg when empty.
All standard A, G, S and D spears. Runs on your existing lines, no re-tooling. Fills at the same speed as stainless steel and is available prefilled with N or CO2.
No return transport, no cleaning, no capital lock-up, no deposit, no risk of loss. Nothing comes back empty, so no reverse logistics, no tracking and no write-offs abroad.
Class A under the Packaging and Packaging Waste Regulation (PPWR). Recycled through standard recycling streams and validated by a life-cycle assessment (LCA).
A single-wall keg with no internal bag, so no second failure point. The barrier sits in the wall itself, which gives one less variable in filling and one less risk in the field.
We make one-way kegs and nothing else, with short lead times when you need them. Every size, from the 12.5L SlimLine to the 30L Prime, is delivered within 2 weeks.
Same beer, same tap, two different cost structures.
| Dolium one-way kegs vs. stainless steel kegs | ||
|---|---|---|
| Feature | Dolium | Stainless steel keg |
| Upfront capital | None, you buy what you ship | Capital tied up per keg |
| Cleaning before filling | Arrives sterile, ready to fill | Washed every cycle |
| Return transport | Nothing comes back | Travels back empty |
| Deposit and tracking | Neither needed | Both needed |
| Empty weight | 0.95 to 1.25 kg | Average 9 kg empty |
| Risk of loss and damage | No keg to lose | Possible to lose and damage |
| End of life | Recycled locally through standard recycling streams | Reused, which only pays off on high rotation |
Buyers rarely open with the sustainability story. They open with compatibility, product quality, beverage integrity and cost, because those four decide whether a one-way keg can work at all in their operation.

Yes. Every keg comes with a standard A, G, S or D spear and runs on your existing filling and draught equipment. No special heads or couplers needed.
The patented APRV (Automatic Pressure Relief Valve) opens at 5 bar and re-closes at 2 bar. An oxygen barrier and a CO₂ loss of less than 5% after 6 months protect the beverage in transit.
No capital, no cleaning, no return logistics, no loss. On low-rotation and export routes that is a lower total cost than stainless steel.
Up to 18 months of barrier protection. The product sheets give a best before date of 18 months after production, and the CO₂ loss stays below 5% after 6 months.
Four volumes: 30L Prime, 24L Prime, 20L SlimLine and 12.5L SlimLine, delivered within 2 weeks. Every model comes with a standard A, G, S or D spear, and can be prefilled with N or CO₂ if you want.
