Coffee chaff is a byproduct of the coffee roasting process that is gaining popularity in various industries for its sustainability and versatility. While it may seem like waste to the untrained eye, coffee chaff is a lightweight, papery skin that comes off coffee beans during roasting. With the rise of environmentally conscious practices, many people are now seeking coffee chaff for sale to use in gardening, composting, bedding, and even packaging. Understanding its uses, benefits, and where to find it can help you make the most of this unique material.
