organic material from municipal solid waste).
Finding of limit conditions for optimal biomass
metabolism.
Pre-treatment test of matrices to be digested.
University of Udine
It is the scientific referee of the spin off project.
RISA has a partnership with the University of Udine
to realize a pilot plan for wastewater treatment
using US-ozone technology.
This innovating project could be object in the future
of a patent application.
