"Endlessly Clever" Design for a Garbage Can With an Endless Bag
From Sweden, the Longopac system
At some point, we've all thrown out a garbage bag that was not completely full, because it contained something foul that we didn't want to fester inside. In institutional settings like hospitals and restaurants, that practice can be extremely wasteful, burning through standardized bags with randomly non-standardized contents.
Swedish packaging company Paxxo has addressed this issue with their Longopac waste bagging system, which they refer to as "endlessly clever." That's because the system utilizes an "endless bag cassette," which is really a long tube of polyethylene--up to 125 meters (410 feet) in length. Loaded into their specially designed Longopac receptacle, which is open-sided, the end user determines how long each individual garbage bag will be.
Here's how it works:

Even with the added usage of zip-ties, the company claims the system still saves C02 in the long run, and confers benefits in "time saving handling, low material consumption and low transport costs." Hygiene is also improved, making the system popular in a variety of industries.
The bag cassettes come in different diameters, lengths and even hues, for operations requiring color-coding operations.
They've designed a variety of receptacle types for different industries and applications:
I'm not crazy about the amount of zip-ties required, but the design is quite clever, and I could see a lot of uses for it on the farm alone.

We had our warehouse floors ground and the propane powered dust collector used the same bag system. They would tie off and remove bags while the machine was running in a non-stop collection cycle. Looked like giant poops as they dropped bags while moving from one end of the warehouse to the other.
This is how my diaper genie works
The combination of scissors dangling on wire and zip-ties are an obvious flaw. I would expect to see an iteration with a heat sealer/cutter intergrated into the design, that would weld the bag shut and cut off the previous one. I guess that would require a power connection or batteries, so I can see why that would not work for all situations... Maybe a more rustic solution is possible? Can anyone think of a way to mechanically tie a knot? You would pull a lever to tie the knot and another to cut the bag? That would be quite satisfying!

Seems like the zip tied end at the bottom would be more prone to leaks.
I'm not sure what I'm missing, but I'm pretty sure this is the exact method most diaper pails use...
