Kitchen waste from a 2-person familiy (remember that meat waste
doesn't go in a compost bin) isn't on its own going to sustain 50
square yards of grass cuttings in the summer. You need a balance or
you'll end up with simple smelly mush

A few card boxes from the tons of packaging mixed in with the grass
cuttings (+ urine) will help with that. And it doesn't really matter if
it gets a bit mushy as it will rot down eventually.

The ideal compost heap/bin will be close on 50% green (in this case
grass) and 50% brown (in this case cardboard). The cardboard will need
to be scrunched up to provide air in the heap/bin, not just torn and
put in flat, as the grass will compact and exclude air. Shredded paper
on its own won't do the trick as, again, it'll compact too easily.
Male urine (and it's not only male but the first output of the morning
;-)) ) may provide nitrogen but the heap also needs air to work
properly - this is why grass on its own doesn't do the biz. Are there
any trees in the garden - if so, collect the leaves , bag them up and
then use them to provide the "brown" bit through the grass cutting
season. Cardboard and grass will take a long time to break down into
usable compost (I've tried it!).
