Following advice at this fount of learning
I bought a Bosch garden 1.8kW shredder at B&Q for 130 euro
(about 85 pounds),
and it has been performing very well.

Now I'm wondering if I can add the output to my wormery?
Will it convert within a finite time to compost?

A few years ago I hired a shredder to clear my back garden and it
composted well when mixed with green stuff and grass cuttings, but I'm
not sure how long it took - I tend to make more compost than I use so it
sits there for a year or three.
