Recycling Plastics to Crop Vegetables in Seawater: 1- The Floating Greenhouse Bottle

摘要

The objective of the study was the design of a floating greenhouse for growing edible plants in the sea. The elements necessary for growing plants in the sea a low cost would be a solar still for producing freshwater and a pot or container for plant support and breeding. To perform the functions of solar still plastic bottles for packaging olive oil were used. With this plastic bottle as top and a Trap for Wasps made of plastic or a metallic Mold to make baked biscuits as base it was possible to build a small solar greenhouse and use seawater to grow some man edible plants such as spinach (Spinacia oleracea L.) and wheat (Triticum aestivum L.) The floating greenhouse bottle can be used for growing plants in lakes or freshwater marshes as well as in salt lakes or in the sea. It would have application for cultivation of edible and industrial crops, algae or biofuels, plants to reduce the greenhouse effect, as a system for the recycling of plastic bottles and to reduce the cost of freshwater needed for Agriculture. By not producing waste is considered an ecological and cheap system to produce some food without spending energy because it uses seawater and solar heat.
