This research aims to control methane and carbon dioxide by a new intelligent approach in landfills. This intelligent approach entails a new configuration of the gas collection system, new permeable hydrophobic polymer medium for gas collection, and an intelligent fuzzy system for modeling and controlling gas transport in the system. The new configuration of the gas collection system consisted of permeable hydrophobic polymer material for better collection. For the investigation of gas transport within polymer, diffusion and convection flow tests were conducted. For gas diffusion through the system, a simulation was done using a box filled with polymer material with multi-ports for gas entrance and sampling. Sensors and a data acquisition system collected information about gas concentration with time and distance through the polymer. For gas convection through the system, a bottle filled with polymer medium was used. An airflow, manometer and flowmeter were used to characterize gas convection and medium permeability. Information collected about temperature variations were recorded to obtain their effect on gas convective flow, and gas diffusive flux through the permeable polymer medium. The Fuzzy logic used obtained information to model and control the biogas transport in the new system to wider range conditions.
