Hello This is from Life after life by Kate Atkinson. The story is set in 1940. The war was going on. Nothing went to waste at Fox Corner. Scraps went to the chickens (‘She’s thinking of getting a pig,’ Hugh said in despair), after bones had made stock they were sent for salvage, as was every last tin and glass jar that wasn’t being filled with jam or chutney or beans or tomatoes. I don't understand the meaning of the sentence highlighted in bold. Would you like to help me? Thank you.
