After coffee is finished brewing, the grounds that gave birth to your cup of joe is often tossed away without any second thought. If your first thought is that the grounds can be reused as compost or fertilizer: you’re correct! Spent coffee grounds are great for rejuvenating destroyed forests (which was previously mentioned in my coffee sustainability post). But there’s several other uses as well, such as in culinary applications or even a part of a personal care routine.
Spent coffee grounds in cooking can add coffee flavor and texture to numerous baked goods, and is surprisingly used as a meat rub as well, tenderizing the meat due to its acidity. As for personal care, coffee grounds work great as an exfoliator, not only because of its texture, but because certain compounds (like caffeine) have a healthy effect on skin by increasing blood flow.
