VALORIZZAZIONE ENERGETICA DEI RIFIUTI, EMISSIONI IN ATMOSFERA E AUTORIZZAZIONI AMBIENTALI

Knowledge and Understanding

The aim of the course is to provide students with theoretical and practical knowledge of the processes and technologies for energy production from waste (biofuels, biogas, biomethane, hydrogen, etc.), gaseous emissions and treatment technologies, carbon capture, utilization and storage (CCUS), and environmental assessments and permits (EIA, IED/Environmental Integrated Authorization, Single Environmental Authorization, etc.).

In particular, the following Sustainable Development Goals (SDGs) of the 2030 Agenda will be addressed:

Goal 7: Affordable and Clean Energy: substantially increase the share of renewable energy in the global energy mix (7.2); strengthen international cooperation to facilitate access to clean energy technologies and research and promote investment in energy infrastructure and clean energy technologies (7.a); expand infrastructure and upgrade technology for supplying modern and sustainable energy services to all developing countries, particularly least developed countries, small island developing States, and landlocked developing countries, in accordance with their respective programmes of support (7.b).

Goal 11: Sustainable Cities and Communities: reduce the environmental impact of cities, particularly with regard to air quality and waste management (11.6); substantially increase the number of cities and human settlements adopting and implementing integrated policies and plans towards inclusion, resource efficiency, climate change mitigation and adaptation, and resilience to disasters (11.b).

Goal 12: Responsible Consumption and Production: achieve the sustainable management and efficient use of natural resources (12.2); achieve the environmentally sound management of chemicals and all wastes throughout their life cycle, in accordance with agreed international frameworks, and significantly reduce their release into the air, water and soil in order to minimize their adverse impacts on human health and the environment (12.4); encourage companies, especially large and transnational companies, to adopt sustainable practices and to integrate sustainability information into their periodic reporting (12.6).

Goal 13: Climate Action: strengthen resilience and adaptive capacity to climate-related hazards and natural disasters in all countries (13.1); integrate climate change measures into national policies, strategies and planning (13.2).

Goal 15: Life on Land: ensure the conservation, restoration and sustainable use of terrestrial and inland freshwater ecosystems and their services, in particular forests, wetlands, mountains and drylands, in line with obligations under international agreements (15.1); promote fair and equitable sharing of the benefits arising from the utilization of genetic resources and promote appropriate access to such resources, as internationally agreed (15.6).

 Applying Knowledge and Understanding

Upon completion of the course, students will have acquired the theoretical and technical-practical knowledge necessary to address, in a professional context, the topics covered in the course and, where necessary, to further develop their knowledge of these subjects.

 Making Judgements

The knowledge acquired and the various learning experiences, including the discussion of case studies and project work, will enable students to develop the critical tools and significant degree of autonomy in judgement required to identify the most appropriate solutions to the problems they are called upon to address.

 Communication Skills

Students will be able to use the technical language specific to the disciplines covered and to communicate problems and their solutions clearly and effectively, as well as to present their work with greater confidence in public.

 Learning Skills

Students will develop the ability to independently update their knowledge through the consultation of technical and scientific sources, legislation, regulations, and relevant sector-specific guidelines.
