How to Use This Calculator

Enter the number of crew and mission duration in days.
Set the waste generation rate per person per day for solid, liquid, and packaging waste.
Input the waste treatment method (incineration, compaction, processing) and volume reduction ratio.
Review total waste mass and stored volume over the mission.
Design waste storage to keep processed waste volume below 1% of total habitat volume.

How the result changes with Crew size

Crew size: Number of crew members.
Mission duration (days): Total mission length.
Recycling level (1-3): 1 = Basic (15%), 2 = Moderate (40%), 3 = Advanced (65%).

Identify Input Parameters
Crew size = 6, Mission duration (days) = 180, Recycling level (1-3) = 2 = 3 input(s) provided
Calculate Daily waste
Daily waste = dailySolidWaste + dailyUrine + dailyTrash
12.66 = 12.66
Calculate Daily for disposal
Daily for disposal = totalDailyWaste * recyclingFactor
7.6 = 7.6
Calculate Total mission waste
Total mission waste = round(wasteForDisposal * missionDays)
1367 = 1367
