Article Synopsis
- The research aimed to create a model to assess airflow resistance through composted organic materials, specifically testing organic material under 80mm from municipal waste.
- The study varied key parameters like hydraulic load and airflow direction over 19 to 25 days while maintaining a consistent material humidity of around 45%.
- A neural network model (MLP/5-9-1) was chosen for its strong performance, indicated by a high correlation coefficient (0.906) and a range of standardized residuals (4.082 to 5.453).
Closed municipal and industrial waste landfill sites create potential hazard of ground water pollution. Pollutants that occur in leachate infiltrate to the soil substratum, where they are carried to in underground water. A municipal waste landfill substratum can be used for elimination of pollutants contained in leachates.

Excessive concentration of mercury in composts used as organic fertilizer may lead to accumulation of this element in soil and plant material. Fractionation of mercury in sewage sludge and composts provides a better understanding of the extent of mobility and bioavailability of the different mercury species and helps in more informed decision making on the application of sludge for agricultural purposes.
