The parameters will regulate the shape with moving components. When the compost is added on, the structure expands. When the compost shrinks, the structure squeezes. The input of wind, temperature, composted items, sun light etc will dictate the ever changing structure to create a new experience over time. The created soil will be used for making a green cover which will represent what can be done with one of mankind´s oldest technologies.
The compost will be a hot compost following the Berkeley Method. This involves a method called "hot composting" which will cut the time cycle from a year to 2-3 weeks.
Essential parameters for optimal composting:
Size of compost container: Minimum of 90 cm x 90 cm x 90 cm, sealed shut.
Size of compost parts: 1.25 mm - 3.75 mm. Softer materials do not need to be divided further, hard materials such as wood need to be more finely divided to decompose rapidly.
Temperature: Around 71° C is optimal temperature for rapid decomposting. If the temperature drops too far below 71°, the decomposition process will slow or stop. If the temperature goes too far above 71°, the microorganisms will die and the process will have to restart.
Humidity: Moisture content of materials should be 50%
Carbon / Nitrogen: Ratio of 30/1
"Green (organic waste)"/"Brown"(paper, wood) ratio of 50/50
Turning frequency of material: Every 24 hours
