| Educational objectives | Dublin 1. The main knowledge and understanding will concern: the processes of environmental pollution; the characteristics of urban waste water and first rain water; the main ideal reactors; physical, biological, bio-chemical purification processes; the main plant schemes for urban waste water treatment. Dublin 2 and 3. The ability to independently apply the skills acquired will concern: the calculation of the main design parameters of primary and secondary sedimentation tanks, sand traps, aerobic and anaerobic biological compartments; the choice of disinfection techniques for purified water; the choice for thickening, conditioning, dehydration and sludge disposal. Dublin 4. Interaction in the classroom on learning topics will allow you to acquire an appropriate language to communicate and exhibit the topics covered Dublin 5. The topics dealt with will be presented critically, leaving the possibility open to further study with references to scientific literature in the sector. |

| Learning verification modality | The exam of the course is an oral interview lasting about 45 minutes, aimed at ascertaining: - the knowledge of the theoretical-methodological contents of the course; - the knowledge of the models adopted to simulate the different physicochemical processes on which the purification of water and solid waste is based; - the knowledge of plant solutions for the removal of pollutants from wastewater, for the stabilization of waste sludge and for the disposal of solid waste; - the competence in applying the proposed computational procedures; - the autonomy of judgment in evaluating the different design strategies. The oral test is also aimed at verifying the student's ability to expound with propriety of language the topics proposed by the committee, to sustain a dialectical relationship during discussion and to summarize the application results of the computational procedures studied. |

| Contents | Biotechnological treatment of waste and organic by-products. The distinction between waste and by-product. Aerobic, anaerobic and integrated treatments. Energy and matter recovery through biotechnological waste treatment in a circular economy. The concept of biorefinery for the production of Biofuels and bioenergy will also be addressed. |

| Educational objectives | The course aims to introduce concepts relative to biomass-waste recycling for green chemistry promoting the circular economy and the end of waste. The course will introduce the drivers of the bioeconomy. Energy vs. food conflict, biomass production limits and other social themes will be implemented to place the bioeconomy in the new world focused on the Circular Economy. Scientific and technical aspects related to biomass origin, production, and characteristics will become part of the knowledge to address the biorefinery concept to produce biofuels, bioenergy and biochemical. |

| Learning verification modality | Written and oral exam on the dates available on the Exam Calendar published on the DICA website. The exam consists of a discussion lasting about twenty minutes aimed at ascertaining the knowledge level acquired by the student. If the student intends to anticipate the exam in a previous year to the one scheduled in the study plan, it is recommended to attend the cycle of lessons and to take the exam in the first useful session after the lessons have ended, thus respecting the semester of teaching planning. |
| Extended program | To provide students with the necessary skills in biomass and waste treatment, to minimize environmental impacts due to poor resource management. Programme: - European and national waste legislation. - Collection and organic fraction of urban waste. - Biomass: sewage sludge, livestock-derived organic materials, agro-industrial wastes and lignocellulosic biomass. - Biomass processes: composting, anaerobic digestion, integrated treatment, biorefinery, biological mechanical treatment and landfill. - Odour control and energy and environmental balance of FORSU treatment. |
