PROCESSI A BASSO IMPATTO AMBIENTALE
Basic knowledge of Chemistry and Biology
Oral examination mark range 18-30/30 The questions during oral examination verify the knowledge about the development of green-chemistry concept, also using case-study, with particulary attention about the biorefinery concept.
The course aims to provide the knowledge and methodological basis to define a process with low environmental impact. The course will then focus on some chemical processes that can currently be defined as having a low environmental impact.
Knowledge and ability
At the end of the course the student knows
What are the main parameters to be evaluated to define a process with a low environmental impact
The correct definitions of green-chemistry and circular economy
The scientific issues to move from the oil-based economy to the green economy.
Knowledge and understanding skills applied
The green-chemistry concepts learned in the course are applicable to all current production processes and form the basis of sustainable development according to the 2030 UN Agenda
Autonomy of judgment
The student is able to correctly evaluate the environmental compatibility of a process and to evaluate if there are processes that concern the circular or non - circular economy.
Be able to use also with examples concepts and definitions such as green chemistry, biorefinery, renewable sources, biodegradable materials, life cicle assesment.
Environmental sustainable chemical processes definitions and applications. Biorefinery concept Green Chemistry approach. Carbon economy approach. Green Chemistry approach: alternative feedstocks and starting materials, alternative synthesis and reagents, alternative reaction conditions. Biorefinery: biomass utilisation, white biotechnology, biofuel. Carbon economy: application of the concept. Important Case History
