1. What Is Garbage-in? (Overview)

Garbage-in is a lightweight, electricity-free composter that turns everyday food scraps
into something useful through the natural power of microorganisms.
It reduces household waste, keeps odors low, and fits easily into small living spaces
-- making it perfect for busy homes.
And because it continues to work even when garbage collection is suspended
due to disasters or unexpected events,
it offers both everyday convenience and reliable peace of mind.

3. Structure & Materials

Hammock-Style Structure

Garbage-in uses a unique hammock-style design that keeps the inner bag lifted off the ground.
By staying suspended, excess moisture can escape into the surrounding air.
This helps maintain dry and airy environment where aerobic microorganisms can stay active
and decompose food waste efficiently.

Water Proof Breathable Fabric

The case cover and inner bag are made of waterproof, breathable material.
Rainwater or other water droplets will not get inside, and the moisture inside
will evaporate and escape to the outside.
This is also an important factor in preventing excess moisture from accumulating
in the bamboo powder.

4. How to Use Garbage-in

Placement

Set it in a well-ventilated location such as a dirt floor, balcony, or sunroom.
It can also be placed outdoors. A location under an awning or similar sheltered area
where it is not directly exposed to rain or snow is ideal.
The case is lightweight, so you can change its location depending on the season and how you use it.
