4. Bio-activator stacking system Consists of stackable interlocking frames, it is adjustable in size and can be moved quite easily Double-walled, with a partial inner third wall which moderates temperature extremes, and therefore speeds up the composting process Ventilation slots and perforated walls help promote aerobic decomposition and inhibit foul odors

5. Bio-orb roll up system The large volume of the spherical Bio- Orb is better insulated at holding heat from microbial activity than other bins of comparable capacity. No mixing, no mess just rolling every 5-10 days. Rolling movement allows contents to decompose aerobically, producing a sweet pleasant aroma.

6. Composter mixer Generous recessed foot treads utilize leg power for easy rotation Custom-designed curved base allows you to mix in place, without rolling Double walled, air-core construction help keep the temperature in the optimal range Air holes provide for ventilation and drainage, if needed Days of the week stamped on the side to help user remember last time it was turned

7. Earth engine- double bin Made from environmentally responsible, weather-resistant frames Galvanized screens & hardware inhibits rust formation 10 Adjustable cedar slats allow easy access to separate storage bins Enormous capacity - almost 2 square yards of space

8. Wormcomposting Worms can compost garbage faster than any other type of composting method. Worms also are very efficient in digesting kitchen food wastes. Each day a worm eats half its weight in food. The care and feeding of worms take far less effort than maintaining an outdoor compost pile. This system is composed of a box to contain the worms; the worms themselves; a controlled environment; and regular maintenance procedures. AUT/ LHTEE
