Canopy Tents

Material A
Aluminum or steel. Either is used for the frame as it needs to be sturdy.

Disposal: Aluminum as a durable material can be recycled and so can steel.

Material B
Nylon, polyester, cotton. Any of these three are used as the actual cover for the tent.

Disposal: The three materials must be placed in the garbage bin.

Best Alternative
As all tent materials tend to be treated and therefore, not particularly environmentally friendly, the choice comes down to the durability of the material. A combination of polyester and cotton appears to be the most durable and long-lasting. This is why they are also commonly used as opposed to the other types of tent materials.
