Is this a con?

They've been giving out free packets of this to loads of gardening YouTubers recently. The guy behind it screams serial liar: he's written a book claiming that Atlantis is actually Ireland and that Ireland is the true birthplace of human civilisation, he runs 'Keystone University' which charges €2,999 for a 3 day business seminar despite not really telling you what you're getting for that money, he describes himself as 'one of the few polymaths on the planet'...

If it actually does contain microbes and they're still viable, it could potentially improve soil, but I have a feeling it's just massively overpriced powdered worm castings/compost/biochar. There is only one trial referenced on the website but I can't find a link to any scientific paper to see the method or results. 

"Reverses Climate Change
By applying 1 kg of Supersoil to 10 acres of grassland, 400 tons of new topsoil is created over time, removing an astonishing 100 tons of carbon from the atmosphere through a process called carbon sequestration."

Soil is mostly a mixture of clay, silt and sand. How is applying 1kg of this going to create 400 tons of soil? Organic matter is just a small fraction of soil. 

"Restores Polluted Soil and Non-Arable Land
Supersoil has the power to turn sand into soil. It can be used to treat soil that has been subjected to chemical spills, oil spills etc and turn them into farmable land"

How is this supposed to work? I have heard of worms and mushrooms being used to remediate contaminated soil, but they work by taking up the contamination and then being physically removed from the area. How does this product break down persistent chemicals and heavy metals like arsenic or lead? Are there any scientific studies which show Supersoil can do this? 

"Top Secret Recipe
Just like Coca-Cola, the exact recipe for Supersoil is a closely guarded secret however what we can say is that Supersoil is made from healthy soil microbes and organic plant matter using a cutting edge quantum compression technique. Supersoil is made in Ireland and is 100% pure, natural and organic. It’s also fully approved by the Irish Organic society and suitable for worldwide use."

'Closely guarded secret' says to me that it's something cheap being sold for a lot of money and they don't want you to know about it. I have a packet of mycorrhizal fungi which tells me exactly what species of bacteria and fungi it contains and in what quantities, as well as what the bulking ingredient is. 'Quantum compression' sounds like absolute woo.
