An innovative way to remove trash from the ISS has been tested and it is brilliant

Space waste could be reduced in the future with a new waste disposal system aboard the International Space Station. Nanoracks designed the system, which utilizes the Bishop Airlock. NASA's Johnson Space Center recently tested it with Nanoracks.

A key element of the new ISS waste disposal system is its simplicity. Even though it relies on incredible technology, a garbage bag thrown out the window can accomplish the basic idea.

According to Nanoracks, the system is more efficient and sustainable than the current waste removal model on the ISS. It was developed in collaboration with NASA's Johnson Space Center. As a result, astronauts aboard the ISS are hoarding their trash and waiting for the Cygnus cargo ship to arrive.

In the aftermath of Cygnus' arrival and unloading the vehicle, the trash is packed into the vehicle. It is then released from the ISS and burned up during re-entry into the atmosphere. The current waste disposal model for the ISS is effective, but it allows for the accumulation of trash for months.

Astronauts can gather their trash in the Bishop Airlock until the Nanoracks garbage bag is full with the new ISS waste disposal system. This bag can hold up to 600 pounds of trash. The bag is then jettisoned into the atmosphere when full.

There is no doubt that the system is a very interesting one and one that has the potential to increase the efficiency of commercial low-Earth orbit operations in the long run. 

Quite simply, the astronauts refit the airlock with a new bag after expanding and jettisoning the previous one. This allows them to store their trash and, between missions, throw it away without waiting months for the Cygnus cargo spacecraft to arrive.

A long-standing problem on the ISS is waste disposal, according to Cooper Read, the program manager for Bishop Airlock at Nanoracks.

There are around two cans worth of trash generated by astronauts aboard the International Space Station every week. As more people move to LEO stations, that amount will increase.

There is a lot to learn about the new waste disposal system for the International Space Station, and testing it now is key to making sure any kinks can be ironed out. This will make the astronauts' lives easier and cleaner.
