The organic waste is arranged in rows of long piles called "rows" and aerated by turning the stack periodically by manual or mechanical means. The size of the row is very important: where the row is too large, the anaerobic zones occur near its center. These release odors when the spinner is rotated. On the other hand, small rows lose heat quickly and may not reach temperatures high enough to evaporate moisture and kill pathogens and weed seeds.
There are a number of specialized spinning rows that significantly reduce time and labor, mix materials thoroughly and produce more uniform compost. Some of these machines are attached to agricultural tractors or front loaders, others are self-propelled. Some machines can also load trucks and wagons from the row.
The rotational frequency depends on the rate of decomposition, the moisture content and the porosity of the materials, and the desired composting time. Because the rate of decomposition is higher at the beginning of the process, the rotational frequency decreases as the wind ages. Easily degradable or high N mixtures may require daily twists at the start of the process, but even then it may be difficult to control odor and leachate. As the process continues, the rotation frequency can be reduced to a single turn per week.
With stringent regulatory controls at the global level, consents for row systems near built environments are becoming increasingly difficult to obtain and row composting is rapidly being recognized as suitable for green waste processing (only in the garden or in the garden).
The leachate liquid waste is released during the composting process. This can contaminate local supplies of land and surface water and must be collected and treated.
Row composting often requires large tracts of land, robust equipment, a continuous supply of labor to maintain and operate the facility and patience to experiment with various mixtures of materials and turning frequencies.
With the row method, the active composting stage usually lasts from three to nine weeks depending on the nature of the materials, the turning frequency and local climatic conditions. In dry and arid climates or very humid periods (high precipitation) maintaining the correct moisture content can be difficult.
