Just firing up the machines doesn't explain how Nulixo would somehow be able to provide their 'biologically digested' , dried, and sorted feedstock at Niagara for test runs.
If you take their webpage as the truth then the feedstock they need to test is subjected to defined process involving precise steps, timing, and in conjunction with a separate 'partner'.
And none of that process is in place in Niagara.
Without that 'biologically digested' dried, sorted feedstock why even bother ? The repairing and running of the machines would lack the proper data and results Nulixo would need to know if they are compatible with their feedstock.
