In the United States alone, more than 145 billion cups of coffee are thrown away annually. The habit of drinking coffee on the street or off the premises has led to a surprising amount of waste, much of which does not end up in recycling bins. On the other hand, conventional mugs can only be reused a couple of times before they end up in landfills. These cups are embedded with native wildflower seeds so they can be planted after use to help replenish arid soil, helping local bee colonies as well. The project was funded through a Kickstarter campaign.
The cups biodegrade within 180 days, creating a layer of nutrient-rich soil in which the seeds can grow. The seeds chosen are those native to the region where the cups will be distributed. Each cup also contains at least one seed of some type of local tree, so we can get trees to grow too. These mugs cost the same as standard, recyclable mugs, so this is a great incentive to attract locals or businesses where coffee is served.
Even if consumers are lazy and throw the cups in the trash instead of a recycling bin, the cup will completely biodegrade in less than 200 days.
