This is a strong, and simple, story, which IMO has major legs:
FACT: A major player in the industry with 720 employees - LRS - is excited about the bioremediation technology.
FACT: LRS is joining forces with ECOS - showing an interest far beyond deploying one unit (at over $600k) as a 'test' or 'pilot'.
FACT: 400 units in S Korea use this - or similar - technology. That's not to be ignored. 400 x 600,000 = $240,000,000
SPECULATION: LRS may well be accumulating ECOS in order to become a public company - with the goal of expanding and deploying these units nationally.
