The amount of solid waste generated in Romania has increased in recent years mainly because of the people lifestyle. Since 2015, all local communities are working for a sustainable waste management using composting as the main method of recycling the organic fraction of municipal solid waste (OFMSW). Composting is a way of obtaining a product from the biological oxidative transformation of OFMSW with less carbon and nitrogen, but more stable, which is called compost and that could enhance plant growth. This paper refers to quality evaluation of compost produced from OFMSW within Covasna-Boroşneu Mare Integrated Waste Management Centre. There were used empirical methods, physical and chemical analysis, germination tests with cress (Lepidium sativum L.) and plant growing tests with lettuce (Lactuca sativa L). No presence of ammonia was identified within empirical test, and the C/N ratio has a typical value for a mature compost but, in the seed germination tests and plant growing tests the plants are dead. The phytotoxicity could be explained by the higher salts content of compost or by other substances that haven’t been analiyzed.
