O Gás do Lixo no Ceará:

Valores e Valor

Abstract

This article is based on the data presented in the dissertation Comparative Analysis of the Technical, Economic and Environmental Feasibility of the Use of Biogas Originating from the Western Metropolitan Sanitary Landfill of Caucaia (ASMOC) of the Master in Planning and Public Policies of the State University of Ceará. This biogas, when turned into biomethane, a renewable natural gas (RNG), is compared to natural gas of fossil origin (NG),
with a view to verifying all aspects involved. Data are presented from an economic argumentative perspective based on technical criteria, addressed in order to point out the feasibility of the joint use of NG and the biomethane generated through biogas from a landfill. The advantages and disadvantages of each are identified, contextualizing the use of biomethane in substitution of or in conjunction with NG, emphasizing the values of these rich energy sources that, within their various applications, can still be raw material for producing hydrogen. The selection of bibliography and the analysis of technical and economic data existing and practiced in the State of Ceará, Brazil, define the methodology adopted in this study. The State of Ceará stands out in the association between public policies aimed at protecting the environment and those focused on regional economic development. Building new landfills shared by several municipalities, according to the established technical standards, will provide the production of considerable volumes of biomethane ‒ a clean energy source.
