The construction of the composting facility in the City of Metković will provide the infrastructure necessary for the biological treatment of separately collected bio-waste, thus contributing to the improvement of the municipal waste management system in the areas of the City of Metković and Opuzen, and the municipalities of Zažablje and Kula Norinska. The construction of compost is one of the preconditions for the establishment of a complete and sustainable waste management system of the Republic of Croatia, and the implementation of this project will directly contribute to increasing the recycling rate of separately collected waste, and in the long term positive impact on environmental protection by reducing the amount of waste that will be disposed of in landfills, avoiding landfilling and reducing greenhouse gas emissions.
