At Clover, we "walk our talk" and unlike other manufacturers use not what just is the least expensive, but what is the most environmentally sound. Over 85% of our compatible SKUs use our patent pending insert, which keeps the cartridge snug and meets ASTM drop test standards instead of a foam insert that is hard to dispose and harmful to the environment. All packaging and residual toner is aggregated and sold to companies that use it in recycled materials. Empty cartridges that are not used in our manufacturing process are either completely recycled or sold to our competitors!
