The minimization of landfill deposition of waste containing biological components represents a big problem, especially in built-up residential areas. The main problem of biologically degradable municipal waste is the quantity and composition of household waste which can have an important influence on decomposition processes already in collecting vessels. An amount of household waste produced in residential areas in the Czech Republic varies from 31 to 337 g/person/day, with an average value of 250 g. Waste of plant material character is produced in the range from 22 to 291 g/person/day. Composts were prepared in the home composters from household food waste. After the end of the composting process, compost does not have the organic component sufficiently stabilized, which is documented by a high value of electrical conductivity of aqueous leachate reaching more than 4 mS/cm and low humification index. The value of the humification index pronouncedly increased after eight weeks from 0.05 to 0.85, while compost from composting of green waste using windrow system have humification index of 3.48. An aim of this work is the determination of properties of composts prepared from HFW in automatic composters and identification of differences compared with composts prepared from a mixture of biodegradable green waste.

Agricultural soils from Dongchuan copper mining area were sampled and analyzed to determine the concentrations of selected trace elements, namely As, Cd, Cr, Cu, Hg, Ni, Pb and Zn. The main objectives of this study were: (1) To determine the levels of trace elements and their spatial distribution in soils; (2) to evaluate the potential ecological risk; and (3) to identify the main sources of risk element pollution. The environmental risks were assessed using five different contamination and pollution indexes. Descriptive and exploratory statistical analyses were performed to identify the relations among the trace elements in soils and possible sources of pollution. Although the values of As, Cu and Zn in the soils were significantly higher than Yunnan background values and exceeded the limits of the Chinese national standards in several sampling points, the most serious threat for the ecosystem and human health was represented by Cd. The main sources of Cu and As were identified mining activities, airborne particulates from smelters and the weathering of tailings, and partly also agricultural fertilizers. The major source of Cd was agricultural fertilizers and partly sources associated with mining and smelting activities.
