What are the procedures in disposing waste materials in bakeshops?

I need to make a boat out of scrap and waste materials.?

• waste materials may consists of straws,glue, icecream sticks etc. And the boat should be able to withstand a certain weight for a given period.

• Answer:

  Meh...I'd just build a pontoon boat. Seal the ends of a bunch of straws. Tape them all together into two big "tubes". Make a deck out of several popsicle sticks and glue the tubes underneath. Done. Heck, the pontoons could simply be pop bottles instead of straws and the deck could be a hunk of cardboard. Of course, any plastic bowl shaped thing such as a -plastic bowl- will float. So will a big piece of styrofoam. In fact, you could carve a block of styrofoam into the basic dingy shape and then cover it with popsicle sticks for an "authentic" look.
