Pilot study of the composition of wastes was carried out in 15 rural family households engaged in agricultural activity. In the study group the average resident of rural areas generates about 166 kg of municipal wastes annually. The conducted studies showed that the composition of municipal wastes coming from rural households changes seasonally. During the periods of summer and autumn, the quantity of bio-wastes increased distinctly. The average mass of wastes transferred to the companies engaged in the collection of wastes in the analyzed rural households is almost 50 kg · M–1. year–1. The studies showed that over 80% of organic wastes (kitchen and garden) is utilized in the place where they are generated. In the studies, organic wastes were collected selectively (in separate bags), which undoubtedly had infiuence on their humidity (70–90%). Laboratory analysis of these wastes showed that the ratio C:N in it was from 7 to 19, whereas pH lay within the limits from 5.8 to 6.9 indicating its very good properties for the composting process. Therefore composting of organic waste from rural household should be recommended as the best way for its disposal and the weight reduction of biodegradable waste going to landfills. Comparison of the analyzed variants showed that some waste other than kitchen and garden does not leave the holding (it is re-used or burned in home hearths).

The studies covered sugar industry. The analyses of wastes and wastefulness indicators in the sugar industry were performed in the paper. The results showed that processing of sugar beet generates the formation of huge quantities of side products and wastes. The values of indicators obtained in individual factories were very similar.

The studies covered the branches: sugar industry, fruit-and-vegetable processing and potato processing plants. The analyses of water consumption and quantities of wastewater formed in 24 production plants were performed in the paper. A comparison of water and wastewater management in three branches showed that the highest water consumption is in fruit-and-vegetable processing. The data collected in the paper indicates the drop of water consumption in potato as well as fruit-and-vegetable industry. The values obtained for sugar industry indicate that it is the least diversified branch.
