Learning objectives
The course aims to provide students with the knowledge for the management of waste biomass of agro-industrial and urban origin, as well as for their possible use to produce goods, biomolecules and bioenergy through biological processes or chemical-physical approaches.
To analyze from the technical point of view the role of agriculture in energy generation from renewable sources, taking into account problems and solutions aimed at improving the overall sustainability (technical, economic and environmental) of the energy supply chains and promote the ecological transition.
Expected learning outcomes
At the end of the course, students will be able to develop alternative solutions to the disposal of waste biomass in a context of bio-economy.
At the end of the course, students will acquire bases and skills for: (i) identifying the different energy chains; (ii) defining technological solutions for energy generation from renewable sources compatible with the sustainable management of agricultural production processes.

Course syllabus
Part 1. Green chemistry in agriculture
1) Definition of biomass, impacts of landfilling, concept of waste and by-product, end waste approach for waste biomass.
2) Study of the tipology of biomass: organic fraction of municipal solid waste (OFMSW), civil sewage sludge, agro-industry biomass, ligno-cellulosic biomass.
3) Chemical-biological properties of biomass: definition and characterisation methods, the concepts of biodegradability and recalcitrance.
2) Biorefinery concept and hierarchical product value approach; development of integrated processes.
4) Biomass transformation processes for agronomic use:
4.1. Composting: definition, process parameters and characteristics of compost (biological stability, repressive pathogenic capacity)
4.2. Anaerobic digestion: definition, process parameters and characteristics of digestate
4.3 Water purification: purification efficiency and sludge production
4.4. Pyrolysis for the production of biochar and hydrochar. Chemical-physical-biological characteristics of the products; Technological use of biochar.
5) Biostimulants from waste biomass: production, characterisation, use.
6) Production of bioactive fractions for agriculture: biopharmaceuticals
7) Recovery of nutrients from biomass: ammonium sulphate; struvite.
8) Odorous emissions: definition, measurement, containment systems.

Part 2. Renewable Energy in Agriculture

PART 2 Renewable Energy in Agriculture The material used during the unit on the plant for the use of "Renewable Energy in Agriculture" (lectures) as well as presentations for the deepening of some topics, Tables and technical documents is available in format pdf on the University teaching application.
Assessment methods and Criteria
PART 1. Green chemistry in agriculture.
The exam will be oral regarding the arguments of the course
PART 2. Renewable Energy in Agriculture . The exam relate to the unit on the plant for the use of "Renewable Energy in Agriculture" is written.
The evaluation criteria aim to verify - through a series of questions on the different topics - the degree of overall knowledge acquired by the student.



Students* with DSA and with disabilities are kindly requested to contact the lecturer by email at least 15 days before the scheduled examination date in order to agree on any individualised measures.
