Waste butter sculptures used to generate electricity

The Pennsylvania Farm Show plays home to some pretty exceptional pieces of art carved out of butter, and this might seem like a tremendous waste of food to some, though once done, these sculptures are put to rest in a pretty eco-friendly way. Here’s how. Instead of dumping them in the trash, these butter sculptures are dumped in manure and are broken down with help from ever-hungry micro-organisms. The breaking down causes the release of methane gas which is then used to generate electricity using methane digesters. The electricity in turn is used to power up farms. This eco-friendly way serves as a win-win mode to disposing off the butter used at the Farm Show, without having to put food to complete waste.
