The Households Bio-Waste Management On The Example Of The Małopolska Region

anglais. An aim of this article is to assess the process of biological waste management from households in Małopolska voivodship. Households are a source of waste biomass, which can be used, inter alia, as a raw material for energy and for agricultural purposes. The use of this biomass is part of the implementation of sustainable development goals, which tools are the bioeconomy and the circular economy.Households are a source of two types of waste biomass: food waste and sewage.Food waste is a particular problem, as 9 mlntonsof food isbeing wasted in Polandandabout third part isbeingwasted by the consumers.To examine Malopolska inhabitants regarding their attitude towards the food waste and waste segregation we run a survey.The results of thisresearch revealed that Malopolskadidnot differ from the consumers of other developed countries.As many as 57% of respondents declared that they were throwing away bread; 54.5% vegetables and fruit.There were noted some differences of consumers behaviour, depending on the population groups of women and men as well as residents of villages and cities. Regardingthe segregation ofawaste, only 21.6% of respondents confirmed that they always segregated the waste. Among conscientiously segregating, there were more women than menand more inhabitants of rural areas then small towns. The second source of biomass generated by households is a sewage.The processing of the sewage and its purification by the Wastewater Treatment Plants is a source sewage bio-sludge. It is a problematic material, but can be potentially valuable due to the high phosphors content. However, in Małopolska, the infrastructure for using the biomass is developing, but not fast enough in a context of constantly growing amount of waste and not in a direction of achieving maximum value from the biomass.
