- The main objective of the course is to provide to students the basic knowledge about the current technologies for vegetal biomass transformations into bioenergy, biochemicals, bioplastics. Besides, the course aims at providing students with proper tools needed to rationally elaborate criteria of choice to evaluate such procedures as well as to improve them using the so-called 12 Green Chemistry principles as guidelines. The main knowledge acquired will be: -knowledge of the biomass definition-knowledge of the main types of biomass, with particular reference to vegetal biomass. -knowledge of the biorefinery concept-knowledge of the main technologies of pre-treatment for the vegetal biomass, preliminary to the diverse conversion processes. -knowledge of the main characteristics of the thermochemical processes, i.e. combustion, gasification and pyrolysis-knowledge of the concept of “platform molecule”-knowledge of the main catalytic technologies for the conversion of those platform molecules examined in-depth during lectures.-knowledge of the main conversion processes of lignin towards bio-chemicals and bioplastics -knowledge of the concept of biodiesel, as well as of the catalytic technologies used for its production.The main abilities will be: -ability in recognizing the proper type of vegetal biomass to dedicate to the production of bioenergy, biochemicals and bioplastics, respectively-ability in developing the concept of biorefinery-Identifying the correlations between the different vegetal biomass pre-treatments and conversion technologies -ability in identifying similarities and differences between the thermochemical conversion technologies of lignocellulosic biomass-ability in developing criteria of choice to improve current conversion processes by using the so-called 12 Green Chemistry principles as guidelines
- Prerequisites
- Having passed the exam for the course "Chimica Organica I" and "Chimica Organica II" is strongly recommended.
- Teaching methods
- Face-to-face lectures on all the topics of the course
- Learning verification modality
- Oral exam. Time of duration: about 30 min. The exam will consist of open questions aiming at assessing the level of knowledge/expertise achieved by the student on the course topics. Further, through the exam will be evaluated the student's communication skills and ability of logically organize the discussion
- Extended program

Combustion characteristics of different lignocellulosic biomass materials and elements of thermochemical processes for its conversion into energetic vectors: gassification, pyrolysis, pyrogassification. Processes mediated by chemical catalysts for the vegetal biomass valorization: the role of Green Chemistry; platform molecules for the preparation of biofuels, bio-chemicals, biomaterials; biodiesel. Elements of biochemical transformation of vegetal biomass. Renewables industries: some examples.
