Meche’s House is a post-earthquake house construction in Pedro Carbo, Ecuador. This
article is based on the analysis of this construction under a specific model called
Circular Economy (CE). The CE analyzes the flows of matter and energy, ensuring
that everything recirculates in the system, causing the so-called waste to become a
nutrient for new processes. This article explains the traditional concept of CE, based
on the butterfly model by Ellen MacArthur Foundation which inserts flows of matter
and energy in two spheres: biosphere and technosphere. However, this article inserts
and analyzes a new one: the human sphere. The system for the construction of
Meche’s House is analyzed especially under the latter sphere, to understand the local
people as a resource within the system flows, emphasizing the post-earthquake context.
Keywords: Biosphere, Technosphere, Waste, Nutrients.
1 INTRODUCTION
The flows of matter and energy in the Circular Economy (CE) can be seen within three spheres:
biosphere, technosphere and human sphere. The system behind the construction of Meche’s
house is a concrete example of the interconnected energy and matter flows that can be translated
as circular. The flows embedded in this system can be seen in the construction materials, in the
design of the house and in the use of skills and labor of the community of Pedro Carbo in
Ecuador. It is important to emphasize the different actors involved, as they are also part of the
flow of matter and energy under the analysis of CE. Various actors such as Meche (a woman
called like that by the community who is the owner of the house that was built after the
earthquake) and her family, residents of Pedro Carbo, PACARI (a company that works with
cocoa farmers in the area) and Ensusitio (an organization that works on construction techniques)
participated in the post-earthquake construction of the Meche house. This article will begin with
a brief introduction of the concept of CE and then analyze it within the context of Meche’s
House.
1.1 The Circular Economy (CE)
The current linear economic system of extracting resources, generating products and disposing of
them, is reaching its limit. This linear system is creating a large amount of waste that is not only
