These tests found that firelogs produced 69 percent less particulate matter, 88 percent less carbon monoxide, and 50 percent less opacity (visible smoke). Our charcoals are an environmental-friendly, safe to use and one of the best BBQ charcoal in most of the Japanese and Korean restaurants and hotels. Our charcoals are unique due to their high level of fixed carbon, making it longer lasting with high heat retention capacity.
