Dry trash is generated mainly through food preparation activities in the form of empty food and beverage containers. Dry trash also results from the use of general purpose wipes (described below), tissues, and the items vacuumed up during cleaning activities.
Containers are provided in which dry trash can be placed. The containers hold a liner in place which can be removed and sealed via a velcro strip when full.
When a dry trash bag is filled, it is removed and placed in a dry trash locker.
It is anticipated that each crew member will generate approximately TBD in3 of dry trash each day.
Since each dry trash bag can hold TBD in3, and anticipating a seven-day mission, TBD bags are required.
This requires that the dry trash locker be of TBD dimensions.
Two locations are provided for placement of dry trash (i.e. there are two garbage pails). Each of these trash lockers will require the space of a filled trash bag.
Note: this size is an estimate only; actual data have yet to be located.
One dry trash garbage pail should be located in the Galley area, and the other should be located in a location suitably far from the Galley so that no crew member has to travel a great distance to reach a trash container. If space poses a severe problem, the second garbage pail may be eliminated.
The dry trash locker will be located under the floor near the Galley.
Wet trash is defined as any garbage that is moist to any degree. This trash has the potential to out-gas noxious odors and therefore must be dealt with separately from the dry trash.
Wet trash is almost exclusively generated as a result of food preparation activities. This includes the cleanup after food preparation.
One wet trash container is provided in the Galley area. This container is similar to the dry trash container in that there is a liner which goes inside. The major difference in this case, however, is that the liner is airtight and has a nozzle on it.
The wet trash bag is airtight to keep any gasses that develop in it inside. The nozzle exists for a similar purpose. It allows the bag to be connected to the Waste Management System so that it may be vented to space.
Once a wet trash bag becomes full, it is removed from the wet trash locker and placed in an airtight locker specifically designed for wet trash. This locker vents to space thereby eliminating the need for any crew member to monitor the status of the wet trash to avoid out-gassing problems.
It is anticipated that each crew member will generate approximately TBD in3 of wet trash each day.
Since each wet trash bag can hold TBD in3, and anticipating a seven-day mission, TBD bags are required.
This requires that the airtight locker be of TBD dimensions.
One location is provided for placement of wet trash (i.e. there is one garbage pail). This trash locker will require the space of a filled trash bag.
Note: this size is an estimate only; actual data have yet to be located.
The wet trash garbage pail will be located in the Galley area since this is where most wet trash is generated.
The airtight locker will be located in the floor under the Galley.
Since the LTV is a completely enclosed environment, it is essential that it be kept free of dirt and bacteria. For this reason, a biocidal cleanser is provided along with disposable gloves for the cleaning of surfaces and the Waste Collection unit.
General purpose wipes are also provided for less intensive cleaning activities.
A wet wipe dispenser attached to the Galley allows the crew members to clean their eating utensils.
Planning for an extensive cleaning of the LTV to occur once per day while the crew is onboard, six pairs of gloves will be required as will one Windex-sized bottle of biocidal cleanser.
The dry wipes are of TBD size and thus it is estimated that TBD will be used per day. Since they are stored in containers that are TBD, TBD boxes will be required.
The wet wipes are of TBD size and thus it is estimated that TBD will be used per day. Since they are stored in containers that are TBD, TBD boxes will be required.
Note: this size is an estimate only; actual data have yet to be located.
All items should be stored in a locker designated for housekeeping supplies.
Some spills may be more readily cleaned through the use of a vacuum cleaner. In addition, the various air filters in the LTV will need to be vacuumed out periodically to clean them of matter pulled from the air.
The vacuum is electrically powered and thus, needs to be connected to an outlet prior to operation.
The vacuum is approximately TBD in size.
Note: these sizes are an estimate only; actual data have yet to be located.
Storage within the locker designated for housekeeping supplies.
