[Mineralization of refuse from medical consulting rooms and municipal refuse in a model landfill].

Abstract

Refuse originated from consulting rooms of medical doctors of five different specializations were disposed of for more than six months in a model landfill. Another variants of the same experiment consisted of a mixture, made from refuse as above with municipal refuse (1:10), and of municipal refuse alone. Using estimation of either CO2 and NH3 evolution before and after disposal, continuous temperature measurement, organic matter and moisture contents, the mineralization process in the disposed refuse was followed. In model landfill which was kept under aerobic conditions the results indicated a low rate of mineralization in refuse from medical consulting rooms. The mixture containing municipal refuse and refuse from medical consulting rooms showed mineralization rate similar to that of municipal refuse alone. If the model landfills were kept nearly anaerobic almost no mineralization occurred in all kind of refuse disposed of.
