enquiry for eco-friendly option for metal spray painting, powder coating, sticker printing and adhesives

we are using metal / SS / aluminium fabricated plates, bodiesand also stickers for face of product. We are presently getting metal paintedfrom a spray painter or powder coating shop. And the stickers are printed withnormal printer and have adhesive at the back. We would like to switch over to agreen option even if there is a little choice in colours and otherwise. It goesin industrial consumption;  attractive color / finish isn't that importantas for consumer products. Can you offer us product or advice?
