Design Option – Plastic Bottle Bricks
The design area chosen by my team is Waste Management. Our aim is to reduce the dumping of Codo’s waste in the environment and provide and alternative purpose for those materials.
The plastic bottle brick is an option that combines plastic bottles, bags, packages, and many other types of dry waste to create a brick much stronger than the traditional one.
A huge initiative to use this brick can be seen at the Eco-Tec's Ecoparque El Zamorano, in Honduras.
The Eco-Tec team built a house constructed with 8,000 bottles with composting toilets and a solar water heating system. The green roof can weigh 30 tons when wet and has been supported by the walls without any extra reinforcement. It was the first house in the world made from PET bottles without using cement in the walls. They built other structures such as a greenhouse. Pic 1 – first PET house, Honduras
This construction system may be applicable to different environments and areas such as eco-tourism, recreation, communal areas (bus stops, parks, communal houses), new housing construction or improvement of it, water storage tanks and etc. The intention is to use plastic waste to create a structure capable of servicing the community.
What is necessary to build a plastic bottle house?
Around 7000 to 9000 bottles are necessary to make a big house. This large amount can create a sourcing problem for the people in Codo, they don’t buy them very often and they even use some for storing coconut oil. The costs are minimum, the plastic and waste used to fill the bottles can be found where it is thrown in the environment, the wires used to tie the bottles are sold from 2.75$ to 5$ the meter. These expenses can be easily divided by the community. Apart from the plastic bottles, sand and some cement leftovers can be used to create a construction mixture to put between the bottles to enforce the walls. The final product is well isolated and
