System with Membrane Cover

Composting & Biological Drying

For composting and biological drying of organic waste with pressure ventilation and membrane cover.

The CONVAERO process takes benefit from the natural biodegradation of organic matters by microorganism existing in waste. Special designed membrane cover is placed over waste heap, air channels in the floor provide sufficient flow of air through the waste.

In this controlled and monitored environment, the microorganism decompose organic matter and heat is produced as part of the metabolic activities, which causes the temperature in the waste heap and under the cover to rise. Depending on client‘s requirements, the process is customized according to the purpose of waste drying or composting.

Biological Drying or Composting

For waste drying, temperature rises to 60 - 70 degree Celsius to evaporate water in the waste. After 2 to 4 weeks, what remains of the waste is a dry, odourless and stabilized substance which is easy to handle and separate.

While for composting, temperature of 60 - 70 degree Celsius sanitizes the waste. The process
is designed to provide sufficient O₂ to maintain aerobic condition and this creates an ideal
environment for degradation of waste.

Flexible, low-emission & reliable

CONVAERO System is very flexible in terms of budget, area requirement and setup time. These features enable users to implement the system in large scale waste management plants, as well as in small scale waste treatment facilities. It can also be operated on a full scale operation with small throughput. Beside these, it is very suitable to be used on a trial basis for feasibility studies purpose.

CONVAERO System is especially effective in solving odour problem which is one of the biggest challenges in waste treatment. Furthermore, energy consumption is relatively low compare to other waste treatment methods. The system is tested and proven with valid references.

For the purpose of composting, waste is reliably sanitized and stabilized after a short process time. For the purpose of biological drying, standard water content in the output waste (after drying) is 20% or less depending on requirement. The system can treat Municipal Waste, Green Waste, Organic Waste, Sewege Sludge or Digestate.
