Model matematyczny wytwarzania biogazu w składowiskach odpadów

There is an urgent need for landfill gas models able either to forecast the yield and production rate of the biogas or to evaluate potential gas migration and related problems. Depending on the approach, different classifications of the models are possible. However, a comparison of theoretical and in-situ data reveals great inconsistencies: theoretical values are generally higher than the practical possibilities of collection. There are two major factors contributing to that discrepancy: the non-homogeneity of municipal solid wastes and the unsteadiness of biogas generation. The implementation of some diverse mathematical models (their general assumptions are presented in the paper) may eliminate such problems.
