Use and recycling of agri-food biomasses

A.Y. 2020/2021
Overall hours
Learning objectives
The course aims to provide students with the knowledge to manage agro-industrial and non-industrial waste biomasses, as well as for their possible use to produce goods and / or bioenergy through biological processes or chemical-physical approaches.
Expected learning outcomes
At the end of the course the students will be able to develop alternative solutions to the disposal of waste biomass in a green-economy context.
Course syllabus and organization

Single session

Lesson period
Second semester
The lessons will be in part in presence and in part using Microsoft Teams synchronously. The number of lessons in presence will depend by the sanitary condition (Student reservation is mandatory by using UNIMI dedicated app).
The timetable of the lessons will be available at . Communications will be posted in ARIEL or sent by email.
Additional activities such as seminars, videos and webinars will be organized or suggested. is the visits to full scale plants will be not allowed, alternative activities focused on food waste valorisation.
Oral examination will be done in Microsoft Teams.

Oral exam (3-4 questions, 20-30 min) using Microsoft teams.
Course syllabus
Introduction: Biomasses: definition and classificaiton Biomasses: chemical-physical characteristics Part 1 Solid state process: organic amendment production; solid refuse fuels production Anaerobic process wet and dry: biogas production; hydrogen production. Part 2 Biotrasnformation processes: - bioethanol; -innovative process: supercritical fluids Part 3 - Agricultural use of biomasses: - digestate use; - biosolids use; - compost use; - agroindustrial waste use. Part 4 Case studies: on field visit.
Prerequisites for admission
Preliminary knowledge of chemistry and biology are required.
Teaching methods
