Presumably GR Engineering built a scaled up version of the lab plant that SRC used in Canada to produce the final product range.
Would be interested to know who is responsible for getting the plant to achieve what SRC achieved. Presumably the engineers at GR in conjunction with the company plus advice from Canada?
With KLL presumably the Germans are on site to tune the plant?

When you refer to incomplete trenches presumably you mean the southern network that was delayed by approvals?
