recycling garbage

Make construction 2x4's from garbage
  [vote for,

Build a machine that allows you to put your household garbage into it and turn it into 2x4’s for construction. The machine would take cans, paper, cardboard, and plastic. It would shred the material into strips. The machine would then heat the materials and extrude them into 2x4’s. The machine could be placed in the strip malls. The consumer would have the option of getting the 2x4’s or money. This would be the most efficient method of recycling.

Although not 2x4s, the same principle... [ldischler, Oct 04 2004, last modified Oct 21 2004]


       Semi-baked. Trex is recycled materials, although it probably not strong enough for structural use.

       What do banana peels extrude as?

       Decking for comedy clubs.

       So cutting things into strips and heating them makes recycled 2x4's? hmm, you learn something new everyday.

       I like it a because [simon61] was trying to include all materials in this product. Would be better if a little more reseach was included, for example how much heat can be tolerated by the plastics, which may not be enough to do any melting or softening of the woods, metals or glasses. bun anyway.

       It could be just a really hot high pressure furnace. All metals evaporate and are distilled off in fractions while carbon from organic materials condenses into diamond. It would pay for itself in days, wouldn't it?

       Trex decking has surprisingly similar construction qualities and load capacity to wood.   

       Reading Simon's idea, I assume that heating the materials together will result in plastic acting as a matrix to bond the other stuff together as aggregate. I expect that this will require a relatively high ratio of plastic and finely chopped particles.   

       This seems like a waste of metal or glass, unless it is somehow decorative. Using construction materials with less embodied energy would make more sense to me, if the goal were eco-friendliness.
