Whether you love hot drinks or not, this invention by Californian based company Reduce. Reuse. Grow is worth taking a look at. They have designed a coffee cup that is biodegradable meaning it won't create any waste... but it gets even better.
The coffee cups also come with seeds embedded into them that are based on the cups geographical location. Stores that participate will either encourage people to plant the cup themselves or return them back to the company for them to plant.
