Internationally, almost 70% of municipal solid waste is disposed of in landfills and may contain hazardous substances in the form of paints, vehicle maintenance products, mercury-containing waste, pharmaceuticals, batteries, and many other products. The present study has attempted to address the problem of hazardous waste in the context of municipal solid waste generated in a typical urban scenario. The study was conducted in year 2013. The sorting of the waste was performed manually. Determining the quantity of hazardous and potentially hazardous ingredients in household waste was carried out on the 10 samples of the collection from the cities of Kroměříž (City 1) and Brno (City 2). Results revealed that the share of household hazardous waste found in Kuchyňky landfi ll was 2.047% of the total municipal solid waste stream. The results are based on actual measurements, where the percentage of household hazardous waste has been estimated based on sampling in a municipal landfill.
