Maping and evaluation of the appropriate composting technologies in order to identify the most suitable option for Narva. The objective of this project is to map and evaluate the appropriate composting technologies in order to identify the most suitable option for Narva. The technical, economic and environmental aspects of potential municipal-scale composting technologies will be evaluated. The most optimal composting approach will form the basis for further development of a system for the separate collection and treatment of biowaste in Narva. Currently, there is no separate collection system for such waste in Narva. Most of the mixed municipal waste is landfilled.
Despite being a simple process, Estonia has relatively little experience in compost production from municipal waste (separately collected food and green waste). Composting is one of the alternatives for municipality-level biowaste treatment with the most potential, as it directly contributes to the diversion of biodegradable waste from landfills. However, this method can also have other positive side effects, including economising on limited natural resources, higher environmental awareness among the population and closing the nutrient loop between urban and rural areas. Composting is therefore an interesting option for municipalities developing their waste management by minimising and recycling the waste that today ends up in landfills.
Expected outcome:
Improvement of waste management system: separate collection and treatment system established and up to 5,000 tonnes of compost produced per annum.
