at my works, loads have fallen leaves have been reduced to mush by parked cars. could this be a very short cut to a usable mulch on my raised beds, or would there be no nutritional value yet? thanks

I think they would be better collected and left in black sacks til next year before using

I would think the leaf mush also contains contaminated engine oil, screen wash and anti freeze!  I should look elsewhere.

or would there be no nutritional value yet?

Also, leaf mould has no nutritonal value, either now nor left for later. It's use is a soil conditioner.

nutritonal to the worms,we must consider the nice underground work force

And worms produce waste=nutrition.
