4.1 Pyrolysis of organic waste


Organic waste can be used as a source of energy. However, its combustion is not always preferable and it generates toxic exhaust gases. We study a possibility of organic waste pyrolysis as an alternative approach to its utilization. We use the flue gas from the combustion of natural gas to initiate drying, and subsequent thermal decomposition of the treated waste. This process leads to generation of heat, pyrolysis gases (containing CO, H2 and various volatile organic compounds), liquid products (higher hydrocarbons condensing in energy recuperation unit) and solid residuum (mostly carbon).

The aim of this study is a conversion of organic waste to useful products, analysis of pyrolytic products, study of possible utilization of these products (as fuel for example), and accumulation of energy produced by the pyrolysis. For this reason we also develop novel phase change materials for the heat storage. In these materials we also use the residual carbon produced from the organic waste. This carbon has a porous character and it can be used as good adsorbent after its activation. Moreover, we also tested its utilization as soil additive.
