Abstract

<p>We have developed equipment that dries the residue produced when extracting coffee (hereafter referred to as "coffee grounds") using a drying machine, processes it into solid fuel using a pellet molding machine, and roasts coffee using these pellets as fuel in a roasting machine (hereafter, the "green roasting machine"). Traditionally, coffee grounds have been disposed of as industrial waste in most beverage extraction facilities, incurring significant costs. Moreover, the roasting of coffee has typically relied on fossil fuels, leading to substantial greenhouse gas (GHG) emissions.Through this innovation, we can not only reduce the disposal cost associated with coffee grounds but also achieve a reduction in GHG emissions. Through this initiative, we aim to set a standard for sustainable practices in the coffee industry and position coffee as a model case for the Sustainable Development Goals (SDGs) in the food sector.</p>
