Best green material/process for outdoor enclosures?

What materials/processes do you think of when I say eco-friendly, outdoor kiosk, or outdoor electronics enclosure, parking meter, etc.?
Most i see are stainless steel or some kind of metal casing or extruded.

If you were to design an eco-friendly durable outdoor electronics kiosk or enclosure or parking meter type product or street traffic signals or lighting, what would you use?

What about plastics? What materials are the Saturn car bodies? What kind of paint?

is this product something subject to year-round weather and potential vandalism?

Yes it will be outdoors all the time. There may be vandalism too.

steel, powder coated eod.

Sheet steel sounds like it would work for my application.

What is eod?

What climate? What quantity? Target market? Like North American contractors might want metal enclosures for perceived toughness, whereas plastic is more widely accepted in Europe and Asia.

Steel will be good anywhere in the world, although it will cost more than plastic…assuming you design the enclosure in such a way as to reduce your assembly time.

I think the Saturn bodies are polypropylene, but not a standard one. I think they add something to reduce the brittleness in cold weather. The paint has an additive to make it flexible too. This isn’t anything proprietary, all car makers use the same plastic and paint on bumpers.

i would be tempted to use a steel laminate with a hard concrete centre.

Concrete would be fun! Higher shipping costs though:/

Great answers.
This would require anchoring into pavement or sidewalks.
maybe the foot would be bolted down into the ground or a cement foundation would need to be made before anchoring.

Use aluminum like everyone else in the Environmental Graphic Design field. Its light (cheaper shipping, less carbon footprint:)), highly recyclable, durable, easily painted, powdercoated, etc.

Its all ball bearings these days.

Very necessary, unless you plan on it being portable.

make light forms.
pour onsite… integrate into sidwalk??

What about that injection mouldable (moldable!) wood/plastic composite, WPC?
