While plastic bottles are recyclable, choosing to reuse them is better for the environment and a great way to turn trash into cheap building materials. One way to do this is to build a plastic bottle wall, good for a DIY greenhouse, a work of art, or just an interesting decoration. Using good materials and design practices will help ensure that your wall is attractive, sturdy and clean.

  1. 1

    Select bottles for your wall. To give your wall the most unified look, choose bottles that are all of the same size, shape and colour--or bottles with a high degree of variety. Avoid having bottles of mostly one kind and just a few of another, unless you have a specific design concept that requires this.

  2. 2

    Collect enough bottles for the size of wall you want. Two litre bottles will contribute roughly six square inches apiece when laid on their sides, while single-serve bottles will give you about half that.

  3. 3

    Prepare your bottles. Remove the labels and wash each bottle thoroughly with soap and warm water, or run through a dishwasher. Leave caps on empty bottles only if they are completely clean and dry inside.

  4. 4

    Create the bottom row of your wall. Attach the bottles to one another while laying them on the floor to ensure that the bottom of the wall is level. Use epoxy, wood glue or hot melt glue as generously as possible. Make sure the bottles line up with one another (unless this is not part of your design).

  5. 5

    Build the sides of the wall to form a frame. Construct the sides as high as you want them to go. Let the glue on each stacked bottle dry completely before adding the next; this will keep the bottom bottles from sliding under the weight of additional bottles on the top.

  6. 6

    Fill in the wall frame. Be sure that each bottle is glued wherever it contacts another bottle, even if this is not strictly necessary in order for the wall to stay up; your wall will be more sturdy the more "mortar" it has.
