Unless you bring your own thermos, paper cups are the real option for on-the-go coffee. But as we all know, producing these simple items cuts down forests of trees and contributes to mountains of waste. In fact, Starbucks alone uses 4 billion paper cups a year globally and most of these plastic-lined cups are never recycled. But a project from Reduce. Reuse. Grow. is handling the coffee industry's paper cup problem by giving these single-use coffee holders a further purpose: reforestation. A company in California has developed the world's first plantable coffee cup, which has seeds in the paper-based material. That means after you're done with the cup, you can tear it, leave it in water for a few minutes, bury it and let nature take over. To prevent the spread of invasive plants, the bottom of the cup details the seed variety and also includes instructions on how to plant it either in the northern or central coast of California. For those who don't want to get their hands dirty, the cup can be put into a Reduce. Reuse. Grow bin where it will eventually be taken to a reforestation location. The cup can biodegrade within 180 days and offer nutrition to plants. The company is trying to put the cup into commercial production and persuade coffee shops to buy the cups. What is a Reduce. Reuse. Grow. bin used for? A) Selling plantable coffee cups. B) Making plantable coffee cups. C) Collecting plantable coffee cups. D) Recycling plantable coffee cups.
