I am a big fan of compost, and I compost all our food scraps and yard "wastes". However, this is but the tip of the iceberg from an nutrient flow perspective. Most of the nutrients end up in urine and feces. In this county, most of those nutrients are lost. They either end up in the ground or lake water or in sewage sludge that gets landfilled instead of recycled. We have been making nitrogen fertilizer from natural gas to make up for the loss during the cheap oil era, but doing so makes no real ecological sense. Getting our "wastes" back into the root zone of plants that can use them is the real challenge I was referring to.
