For example, making recycled aluminum requires only 5% of the energy that it takes to make aluminum from bauxite oreBut unlike aluminum, are there materials (like paper, plastics, etc.) that require more energy and resources to recycle than to make from raw materials?

The short answer is yes,It's a very complicated thing to figure outYou have to factor in the cost of gathering up the recyclables vsthe cost of gathering the raw materialsIn your example of aluminumBauxite ore is gathered in mines on a large scaleSo it's very cheap to move tons of oreAluminum cans gathered on the curb side require a lot of trucks driving around to pick up a few cansThat factor is not included in your 5% statement.
