Waste is obsolete. Standard building industry practices are harmful to the environment. Non-traditional construction methods were examined as alternatives. Circular design logic was the guiding principle in material choice. Additive manufacturing is a proven modern method for building construction. Research on 3D printing case studies revealed that recycled plastic is a proven material and readily available. Removing plastic waste from the environment and sequestering it in architectural components gives the material a new purpose. The component of focus was a building block for a wall assembly. Inspiration was taken from the hexagonal Basalt rock formations found near volcanic fault lines. The final design included interlocking hexagonal block pieces linked and stacked together to form a wall. Additional structural support is provided by driven pilings that pass through shafts in the wall blocks. A full scale assembly would use filament made from recycled plastic to print all necessary blocks. A kit assembly was proposed that included the quantities of each block type required to build an example structure plus additional store-bought hardware.
