Abstract: Multiple Tray Vermicomposter with Thermal Siphon Airflow is a vermiculture composting device that uses earthworms to create compost where worms eat and digest food to excrete compost. It is a multiple tray system with a base and a lid. New compost trays with freshly loaded food and bedding are stacked on top of older trays containing worms and compost to instigate a continuous upward migration of the worms thereby creating continuous compost production. Compost trays have permeable bottoms to allow worms to pass through. Compost production is accelerated from thermal siphon airflow to provide ample airflow to the worms without the requirement of a power source. Light-tight air-permeable connections between trays, lid, and base, also accelerate compost production by keeping the worms completely dark. If worms fall through the bottom compost tray, there exists a ramp to enable the fallen worms to climb back into the bottom compost tray.

Abstract: Wire trellis cable trays (10, 10') made of cross wires (1) and longitudinal wires (2) connecting the former are to be made stackable so that they can be stored and transported in practical groups in a space-saving manner. For this purpose, the side legs (3) of the U-shaped cross wires (1) are crimped toward the outside at a certain height, resulting in a proportional widening of an upper portion of the tray cross-section. The stackability (with the cross wires being slightly offset in a longitudinal direction) is thus attained.
