Windrow gases

Composting - a living process!

Composting is an aerobic process (with oxygen). Therefore, a well-aerated compost windrow is a requirement for a proper decomposition. Valuable information about the aerobic decomposition process can be obtained by

measuring the carbon dioxide (CO2) and oxygen (O2) content of the compost windrow, as microorganisms consume oxygen in the course of the decomposition process, converting it into carbon dioxide.

Windrow gas instrument

Especially in the case of unaerated compost windrows, the measurement of windrow gases is important in order to guarantee a sufficient oxygen supply and to better plan turning times. As the microorganisms respire, they consume oxygen while simultaneously forming carbon dioxide. If the oxygen content drops too low, the process may reverse. In addition to high odor emissions, this also produces greenhouse gases such as methane.

Our electronic windrow gas instrument, operators like you can get an overview of current process conditions. The instrument measures up to seven different gases simultaneously and is also easy to use and low-maintenance.

Our standard windrow gas instrument is equipped with three measuring sensors for measuring the most important composting parameters (O2, CO2, CH4).

Technical data:

Standard sensors:

  • Oxygen (O2)
  • Carbon dioxide (CO2)
  • Methane (CH4)

The five additional sensor positions can be equipped with the following sensors, for example.

  • Ammonia (NH3)
  • Hydrogen sulfide (H2S)
  • Additional sensors on request

Carbon dioxide measurement

Due to the formation of carbon dioxide in the decomposition process, the compost windrow may begin to rot. To prevent this, the windrow must be aerated or turned over. With our simple, analog CO2 instrument, you can quickly gain the information you need about your rotting process to allow you to respond effectively. In addition, the instrument boasts especially easy handling and maintenance.
