Hi, yes your bottom bracket is scrap, but this cheap type is still available to buy from a decent bike shop, The chainset ( large cogs ) will need to be removed with a crank extractor and thenusing a punch and a hammer, undo the side you have photoed by tapping it in a clockwise direction. Then using a suitable spanner undo the bearing cup and remove the bearings and spindle, Simple!!!
Alternatively try filing the burrs of the spindle and fit a new crank, these are available separately, and put some weak threadlock ( halfords ) on the bolt threads. All the best.
