the higher the rate the more worms that surface from my experience

Wrong, the volatile solids in the feedstock are decomposed which is what produces the biogas. The consequences of this, is much less odour than the original material before it was put through the process.

O, o dear must something else their spreading around here under the digestate banner and dribble bar tanker and lagoon set up then?

If the material has qualified as a 'quality digestate', then the level of inert material has strict max levels of volume and size, and they are very small.
Their are many different types of digestate ranging from agricultural (crops and muck/slurry's) C&I which is food and commercial / industrial waste and of course sewage sludge (secondary).
All have different types of permitting and regulation, if the digestate is to be spread to land.
Know what your getting (NPK values) and know the source, and ask if all regulations are met. Only cowboys and chancers will not be able to answer those questions, as heavy fines are waiting for those that don't.

We know where it is, where it is from and know who spreads it.
Still stinks.

And what is the composition and NPK values ?

What sort of food waste ?

I think the smell of it may depend on the process at the plant and the feedstock involved.
I can't see the stuff is that kind to worms or soil life- it's anaerobic and comes out steaming sometimes. It's also very potent because the nutrients in it tend to be quite readily available.
I tested a variety of weed seeds that had been incubated in digestate and tested them with tetrazolium, in line with most other studies, the seeds seemed to die quite readily.
It's like slurry, if you bury the land in it: you're doing it no good. No different to FYM, either. The industry needs to be seen to be applying this stuff carefully and properly managing and recording what nutrients are put where and when. Cowboys spreading dung into the hedge and absolutely burying land in it do no one any favours.

Would say supermarket but not 100%

I'd be very reluctant to accept digestate from a plant using that feedstock because of the potential for plastic residue.
