As posted above the key part of the tech is the new resin.
The difficulty (not impossibility) of recycling fibreglass in the past
has been separating the glass from the resin and the toxicity of the resin. >If the stuff is designed explicitly to overcome these problems then
we assume it's now easy to divert the glass component into traditional
glass reuse streams including of course making more fibreglass --
something that has been done before but was expensive.

Fibres (glass, carbon, kevlar or other material) need to be long and
clean if they are going to be used for structural purposes. Most of
them are hopefully in that condition when they go into a structure but
I don't see how they can be stripped from their resin without physical
damage or leaving residue of the resin on the fibres.
Nor can I think
of a use for fibres in this condition. The original news item gave no
clue about how these problems would be handled. It is for this reason
that I have no confidence in their claim that "The materials can then
be reused in new applications after separation".
The resin is another matter. It's astonishing what chemistry can do if
one puts enough energy into the process.

first. I will be interested to see how soggy wood and PET foam
(previously soaked in a mild acid solution) will be recycled. I
suspect the required "new products matching the technical properties
of the materials, ie. in the automotive industry, or in consumer goods
like flight cases and flat screen casings" are the product of the airy
wave of a hand.
Assuming that such products can be found, I leave you to think of the problems entailed in matching the variable rate of supply of recycled
wind turbine materials to the need for a constant supply of materials
needed by a manufacturing industry.

You apparently have a one-track mine. I don't think you can be a good engineer. A good engineer has be inventive in applying scientific
knowledge to solve problems.
Fiberglass is spun from molten glass. You melt the old fiberglass to
make new fiberglass. Nobody re-uses old fiberglass by cleaning it.
Use adhesive-remover or paint-thinner to soak the epoxy-fiberglass. The
epoxy will soften up. Put the blob into a hydraulic press to squeeze out
the epoxy gloop. Melt the remaining fiberglass mess in a furnace to get
back molten glass.
The epoxy gloop can be injected under high temperature and heat into
molds to form hockey pucks, bowling balls, etc.

This article describes how glass is made from sand:And sand is iron ore? Well, it is in some parts of the world but see
https://www.explainthatstuff.com/glass.html
https://duckduckgo.com/?q=iron+ore&t=newext&atb=v211-1&iax=images&ia=images
"In a commercial glass plant, sand is mixed with waste glass (from
recycling collections), soda ash (sodium carbonate), and limestone
(calcium carbonate) and heated in a furnace. The soda reduces the sand's
melting point, which helps to save energy during manufacture, but it has
an unfortunate drawback: it produces a kind of glass that would dissolve
in water! The limestone is added to stop that happening. The end-product
is called soda-lime-silica glass. It's the ordinary glass we can see all
around us."
