PIZZA DAY is an apple brand of “Bishu Wool,” one of the world's top three wool production areas. We aim to solve environmental problems (mass production/consumption/disposal) by constructing a circular economy that converts wool products into fertilizer using special technology. By introducing membership systems and loyalty programs that utilize NFTs, it is a ReFi (regenerative finance) project that creates new experience value and incentives for environmentally good behavior, and realizes a circular economy.
