Waste is generated in almost all human activities – industrial production, building and construction processes, transportation, services, agriculture, in everyday life of the population. As the individual waste types represent diverse levels of hazard to the mankind and to the environment, a due attention must be paid to waste treatment and disposal; it is desirable to proceed systematically. Many sorts of the so-called waste may be recycled, waste created in one specific industry sector may be utilized as a raw material in another. A multitude of other materials may be incinerated and well serve as a thermal energy source. The last option is depositing waste in controlled landfills.
