Waste Energy generator

Today, my Cities and Sustainability class went on a field trip to a nearby waste energy generator plant. The facility, located in Bridgeport, takes garbage (excluding food scraps and other non flammable waste) and burns it to generate fuel. Their revenue comes from the disposal of waste as well as the production of electricity. The room where all the trash went into was the size of at least a football field, and four stories tall. What do I think about waste? They are such a waste!!!
