Innovative research to support the achievement of national targets aligned with EU policy regarding waste management in the context of the concept of circular economy, acronym INODES

Abstract

The main objective of the project is to carry out research in the field of waste management generated by different sectors activities (main waste, bauxite refinery mud, mud purification station) in order to identify innovative solutions for characterization and capitalization in the context the concept of circular economy. The analysis carried out in the studies shows the following: - for the main categories of waste (municipal waste, packaging waste, bio-waste and waste with critical content), both sorting techniques and recovery / recycling techniques are implemented at European level, but technologies are needed not to generate too high a cost and thus to bring economic benefits; - regarding the red mud (bauxite refuse waste), the analysis carried out on the information available in the literature regarding its possibilities of use, reveals the fact that there are concerns about the application of technically and economically viable solutions; - in order to meet the combustion self-sustaining condition (lower calorific value greater than 1150 kcal / kg, according to the TECHNICAL STANDARD of January 10, 2003 on waste incineration), the sludge from the treatment plants should generally be dehydrated to a lower humidity content 40-50%, depending on the type of sludge treatment.
