With the constant growth of agendas and public policies associated with the decarbonization of various sectors that make up the global economy, financial resources are increasingly being injected into the market through tax incentives or public and private financing for the modernization and/or implementation of production processes that enable countries to achieve the goal established by the United Nations (UN) regarding the restriction of the increase in the average temperature of the planet and, consequently, the mitigation of impacts on various dimensions of the environment caused by anthropogenic actions. In view of this, a significant portion of the population has directed efforts towards promoting ways to restructure the global economy, currently based on resources derived from petroleum and its derivatives, into an economy that seeks to balance and find equilibrium between the extraction of natural resources and their regeneration. Although various scenarios developed by international agencies demonstrate that there will be a diversification of primary sources through the increase in resources that reduce, neutralize, or eliminate the negative impacts caused by human actions on the environment, there will still be room for fossil fuels in the global economy. This diversification is related to the promotion of the energy transition from fossil sources, primarily natural gas, to renewables; those involving the production of gaseous fuels such as biogas, synthetic natural gas, and synthesis gas from biomass; and how these relate to the latest concepts of economic organization, such as the Circular Economy, Industrial Ecology, Short Supply Chains, etc. In view of this, in order to reduce the implementation timeline and investment in capital projects, this thesis suggests a concrete methodology/systematization for the development of projects that fully align not only with sustainability concepts but also demonstrate investment cost and financial return based on environmental and economic aspects in their initial development phase, where business opportunities are identified to bring reliability and security to the investment allocation decision-making process. To achieve this, it is evident that the investments to be made require a security foundation. For this purpose, the thesis suggests that the availability of raw materials be evaluated through an indexing process to categorize and classify the main raw materials found in agricultural production, livestock, aquaculture, and urban solid waste that can maximize production. Annual production data for different crops and species were used to determine their residues and estimate, through the biochemical potential of methane, biogas production conditioned by the existing local supply chain infrastructure available in the national territory. However, to predict future market behavior for investors, the thesis links indexing to the prediction of raw material availability for use in biogas production through the application of machine learning algorithms. This prediction provides strategic planners and decision-makers with reliability regarding future raw material production, its supply to production units, and also ensures the supply of biogas to consumers, enabling medium and long-term production planning. With this information, an analysis is proposed that integrates different aspects that enable the formation of three essential indicators to be used during the decision-making process through multicriteria analysis. The proposed approach seeks to integrate technical analysis, optionally evaluated by the Technical Readiness Level, which assesses the readiness of technology for use, economic analysis, where the financial viability of the business attractiveness and the evaluation of environmental impacts of the production process are included. Thus, a comprehensive analysis of a feasibility study is demonstrated, systematized by different essential techniques with the aim of proposing a project development methodology for the production of biomethane and hydrogen from biogas.
