The volume and structure of solid domestic waste in Ternopil region are analyzed. Our research in the Baikivtsi Utc proves that community residents dump less organic waste in containers (about 20%, which is twice less than in the regional center) because they can compost food waste using it as fertilizer for personal use plots (gardens).
The volumes of organic waste fluctuate significantly throughout the year: the largest amount of them ends up in containers from May to September. The community residents throw out the least of organic waste in winter. One of the reasons is that there is a gradual replacement of last year's harvest with a new one. The habitants of the Baikivtsi Utc throw more paper away during the warmer months. The following types of paper prevail: offset - 33%, newsprint - 29%, coated - 4%, cardboard - 12%, designer - 5%, packaging - 16%, self-adhesive - 1%. In winter, most of the paper is burned to heat buildings. Among the scrap are mostly cans and metal lids (from bottles and cans). Ferrous metal almost never gets into containers due to the fact that it is profitable to sort it out and there are no problems to hand over scrap metal, since scrap collectors often come to the villages and offer quite decent price for it (therefore, there is no need to waste time transporting the metal). The plastic waste of the community includes plastic bottles from water, oil, household chemicals, canisters, plastic bags and ets. Among the various types of plastic: Polyethylene terephthalate or PET - 17%; high-density polyethylene (HDPE) - 29%; polyvinyl chloride or PVC - 4%; low density polyethylene (LDPE) - 34%; polypropylene, PP or PE - 8%; polystyrene, PS - 6% and other - 2%. The research showed that the following types of glass prevail in the structure of the cullet of the Baikivtsi community: window glass - 8%, technical glass - 3%, Plexiglas - 5%, triplex - 3%, glass from chemicals - 1%, ceramics - 10%, bottles - 70 %
The survey showed that only 3% of the community's residents completely sort garbage, about 80% of them sort it partially, and almost 20% do not sort waste at all (and 12% of them plan to do it in the future). The reasons for the low level of waste sorting are not surprising, since, in addition to the low level of environmental awareness of the residents, there no proper conditions for sorting solid waste.
The environmental advantages of sorting and recycling solid domestic waste were evaluated. In particular, the volumes of biogas that can be formed from the annual volumes of solid waste accumulation in the Baikivtsi united territorial community of Ternopil region, as well as the assessment of the environmental efficiency of recycling waste paper, plastic, glass were calculated. The cost of the Baikivtsi Utc solid waste as a secondary material resource will amount to UAH 2,051,943 per year, which can be a significant profit for the community.
Key words: solid domestic waste, united territorial community, sorting, utilization, recycling ecological culture.
