The South African designer Heath Nash took part in the HIFA performing arts festival in Harare, Zimbabwe, 2011, where he created in cooperation with local craftsmen shading structures made out of found and dumped material and PET bottles. The shading on the image to the left shows a triangular construction made of steel perforated L-profiles. Wires are spanned between the profiles and on these wire the blue PET bottles are fastened. The bottles are empty and therefore very light, thus the wires are sufficient to hold the structure.
In Guatemala a technique is used which was invented by Susanne Heisse. Plastic bottles are filled with plastic garbage found on the streets: plastic bags, wrappings, pieces of styrofoam, and so on. The bottles remain light and obtain a slightly higher isolation value. For the construction of the building it is necessary to construct a simple frame, either of wood or concrete. The bottles are fixed within the frame between two layers of chicken wire fencing. The wall is then covered and stiffened with cement mortar.
Because of the climate conditions there is no need for very high isolation values. The bottles are only used as filling to reduce the amount of cement that is necessary to make the walls. There also plays the role empowerment: the school children and people of the neighborhood are involved in the construction of their own school which is possible because the technology is very straightforward and does not involve trained labour. Finally, the participants learn from this how to build structures from on-site resources and garbage.

Three giant fish made out of PET bottles was an installation that was part of a United Nations Conference on Sustainable Development. The three fish were created under the slogan »recycle your attitude« and should resemble a family. The sculptures can be lit at night in various colors.
