Hazardous waste incineration in context with carbon dioxide.
The Kyoto Protocol of 1997 demands an emission reduction of climate-affecting gases in various industrial sectors. In this context CO2 is one of the relevant gases and waste management is one of the relevant sectors. Referring to the situation in Europe, waste incineration is one of the major sources of CO2 in the waste management sector. The Kyoto Protocol, however, only covers CO2-emissions originating from fossil fuels, whereas the incineration of renewable materials, e.g. wood, is considered to be climate-neutral since it does not make any net contribution to the CO2 inventory of the atmosphere. Unlike the situation with municipal waste, there is little if any information on the CO2-emissions caused by the incineration of hazardous waste in specialized plants, and the renewable fraction in these materials. The present paper focuses on this gap of knowledge. Taking the full-scale hazardous waste incineration plant in Biebesheim, Germany, as an example, a carbon balance was set up for the whole-plant taking into account all other material flows. Afterwards the determination of the proportion of renewable materials in the hazardous waste incinerated by means of the radiocarbon method (14C) is reported. On the basis of the results, optimization potentials are discussed.
