Can I still use my compost?

I used to be a keen composter even though I never used it. Veg peelings, tea bags, shredded letters, dog hair, Guinea pig sawdust ect.
For some reason I stopped using it about a year ago and today I decided to start doing it again but it was slightly dry and zero worm activity.

Iv mixed it all up thouroughly with some Guinea pig sawdust and a hand full of grass clippings and watered it.

Will it all work its self out over time and become healthy compost again or have I to get rid and start a new?

 

It will be ok, just keep it damp and let the microbes break it down.
Sawdust can take a while though.

 

It's ok iv no plans on using it I'm just a keen recycler.
I keep saying I'm going to get an allotment but never do.

I might have to limit how much sawdust I put in though
