"We aren’t anywhere near running out of space for landfill. The Earth is huge and we are good at digging deep holes. Space will never be a meaningful constraint." While true in general there is a very big problem called NIMBYism (not in my back yard) where a great many places refuse to allow new landfills--resulting in the refuse having to be transported very long distances--and thus using a great deal of energy for the transportation.
