Prerequisites: Environmental Sanitary Engineering; Chemistry; Microbiology, Organic Chemistry and Biochemistry
Target skills and knowledge: The aim of this course is to enlighten the state of the art in technology, organizational and legislative developments and practices and financial burdens and benefits of handling solid wastes.
The course provides an understanding of technical issues and the management of solid wastes.
It considers solid waste policy (both domestic and international), and examines appropriate methods of storage, collection, transfer, treatment and disposal appropriate for industrialised and developing
At the end students will be able to understand the principles and techniques of solid waste management, including the legislative, environmental, technical, economic and social drivers.
Examination methods: The exam is composed by the following parts:

- written examination at the end of the course

- exercises carried out by the group of students during the course lessons
The group of students (maximum three students each group) will work in class under the supervision of the professor
Assessment criteria: - written examination 70%
some basic exercises (first part of the written test) are compulsory to pass the exam

- groups' exercise during the course lessons 30%
the evaluation is for the whole group and this means that each component will get the same mark
Course unit contents: Waste management systems and strategies:
the EU hierarchy of waste; the Rs and 3Ss concepts; from triangle to circle; the "Zero Waste" theory
Waste production and quality in Africa and in the rest of the world
Analysis and characterisation of waste: IRI, B21, Heating values, TS, VS, others
Glance at the current international legislations about waste management.
Resource recovery and disposal of residues
Waste collection and transport: vehicles and transport stations
Separate collection and material recovery: different collection possibilities (door to door, curbside bins,
containers, etc), volume of the bins, cost analysis
Mechanical selection schemes and processes, efficiencies and different possibilities
Separation of single fractions.
Recycling and recovery processes of material (paper, plastics, glass, etc.).
RDF (refuse derived fluel) production and possibilities
Biostabilization processes for the biodegradable fraction: low and high quality composting process and
different technologies
Energy recovery from waste: biological and thermal processes
Anaerobic difgestion: different energy recovery possibilities and different technologies and plant
Management and disposal of residues.
Landfill technologies and design: strategies, materials, barriers
Processes in landfills: aerobic, semi-aerobic, anaerobic and hybrid landfill
Leachate collection
Leachate treatment and technologies; cost analysis
Biogas collection and treatment.
Top cover systems and closure of landfills.
Applications in developing and low income countries.

Solid waste production calculation
Mass and energy balance for different management systems and treatment plants
Separation efficiencies calculaton
Composting plants and oxygen need for organics
Specific landfill operation and design - barriers and leachate/biogas extraction
Planned learning activities and teaching methods: Frontal lessons, exercises, on field survey; seminars
Additional notes about suggested reading: Handouts
