Chileans consume a large amount of bread each year, with each person eating around 220 pounds. However, much of the bread purchased from supermarkets goes stale and is thrown out. The document proposes collecting stale bread, soaking it in water to create a sponge-like substance, and then baking this at high temperature to form "BrickBread" - a hard brick of dried bread that could be reused in cooking or in emergencies.
