Life Cycle Analysis
23 April 2001
Vermicomposting is the process of creating reasonably odorless compost by red worms feeding on microorganisms that degrade organic matter such as food waste. The worm castings (excrement) are nutrient-rich in usable forms for plants, and therefore make excellent fertilizer.
INPUT = ORGANIC MATTER
SYSTEM = CONTAINER + “NATURE”
Basic design considerations
Size: 1 ft3 space/lb “food” per week
Temperature: 32 ºF < T < 85 ºF
Green design considerations
Packaging (commercial, shipping)
Source reduction: no container
OUTPUT = WORM CASTINGS
