There’s always a second chance
Even you’ve minimized it, there’s always a certain amount of waste associated with food - food packaging or kitchen scraps. Give this waste a second chance! You can use kitchen scraps as compost for plants, or why not replant the vegetables from the scraps that are going to be thrown away? You can put the bottom of a lettuce or a spring onion into a small jar of water and, once rooted, plant on in soil. For food packaging such as paper, cans, plastics, sort them using waste sorting bin so that they are easier to recycle.
