Earthbags Made from Recycled Fishing Nets — 7 Comments

  1. Hi, I’m Dale the writer of this idea on the Permies Forum. There was some discussion beyond the single posting that was transferred to here. I don’t know how to move it all or whether this would be allowed but it may be useful. I will check out this forum from time to time. Thank you.

  2. Been thinking perhaps recycled fishing nets here in Homer, Alaska wrapped around multiple courses of bags might replace, or at least enhance, barbed wire. We are in super earthquake country.
    Draped over outside of bags could they also substitute for chicken wire in plastering?
    Your thoughts?

    • Fishing net may enhance the strength of earthbag walls, but don’t skimp on barbed wire, rebar pins or other reinforcement in earthquake zones. You’ll have to experiment and see if the plaster sticks to the fishing net. I tried a sample and it did not bond at all. The holes in the mesh were too small. Plaster mesh adds a lot of strength, so don’t take any chances. Test everything carefully.

  3. I know that recycled fishing nets can be used to reinforce concrete, if washed well to remove any salts accumulated (salt will degrade concrete). However, I am unsure that using nets to package trash to form walls would work well, due to the fact that most trash compacts when weight is applied to it, unlike earth will (beyond a certain point). Any roof would have to be supported by poles or beams, and not held up by the netted bags. Plastic, when kept away from UV rays, will last almost forever, and thus might be able to be used for wall infill, but not as a supportive material. The plastic would need some form of plastering or cob material to protect it. Some new forms of plastic are being made from corn, instead of oil, and thus will biodegrade over time. However, at the present, this bio-plastic is in the vast minority, but is likely to grow with time.
