Nowadays, waste management represents one of the biggest challenges we face. The aim of this paper is to present various alternative methods of biowaste disposal and to analyze their impact on the waste management system. Key information about biowaste is provided, including its composition, processing methods and potential as a resource. Current situation in the Republic of Croatia is further described, with emphasis on biowaste disposal strategies and current measures to improve the situation. The following sections describe methods for reducing biowaste that are closely related to the dietary habits of population, from proper food storage to correct interpretation of product labels. The processing methods are then described, including conventional composting, bokashi composting, vermicomposting, with the possibility of installing food waste grinders in apartment buildings being further analysed. Technical and economic factors for the implementation of food waste grinders is further analysed, from which three models are created using MS Excel, each for different percentages of interested users. The result of Model 1, with 30% of users interested in food waste grinders installation, shows that the amount of bio-waste collected by trucks annually would be reduced by 534 tons, resulting in annual cost savings of €56.358 for its collection and disposal. The result of Model 2, with 40% interest in the installation of grinders, shows a reduction in bio-waste of 720 tons, resulting in savings of €75.144 for the collection and disposal of bio-waste. The result of Model 3, assuming the highest interest in the installation of grinders at 60%, shows that the amount of bio-waste would be reduced by 1.068 tons, saving €112.760 in collection and disposal costs. With 40% cofinancing from the Fund, the investment payback period is expected to be 7 years. The results are presented graphically, and a conclusion is drawn with a proposal for the most optimal course of action.
