I recommend Green Toys highly. I purchased the Green Toys Recycling Truck as a gift for my nephew. When it arrived, it was a bit bigger than I expected but I considered it to be excellent quality.
Most of the Green Toys are made from recycled milk jugs. I say "most" because some of the Green Toys come with other pieces that I'm guessing are not made from plastic jugs such as the pizza box and order forms in the Green Toys Pizza Parlor. You can read about some of the other positive qualities of Green Toys in the descriptions on Amazon (such as many of the food sets state they are dishwasher safe). Oh, and did I mention that they are Made in the USA!
