In ancient Persia, kitchens were equipped with a built-in composting system known as 'kashk.' Kashk involved collecting food waste, vegetable peels, and other organic matter in designated containers or pits within the kitchen. These containers were then covered and allowed to decompose over time, creating nutrient-rich compost. The resulting compost was used to fertilize Persian gardens and agricultural lands, contributing to sustainable food production. The Persians recognized the importance of recycling organic waste and maintaining soil fertility for their agricultural practices.
