Sustainable energy economics in Latin America has become relevant due to the region’s dependence on the oil market and the disruption caused by the COVID-19 pandemic. A systematic review of the ten major economies in the region based on gross domestic product is conducted. We primarily analyze production performance of hydro, wind, and solar energies, in terms of total gigawatt hours produced, current participation levels in energy matrices, and total installed capacity. Current and future trends and legal frameworks for each technology and country are discussed. Our analyses indicate that Latin America and the Caribbean can potentially increase the usage of renewable energy sources given a plethora of natural resources, favorable geographical and climatic conditions, and existing large-scale hydro installations to counteract the inconsistency of wind and solar projects. Therefore, governments in the region must overhaul sustainable policies to increase awareness and reduce energy dependence on foreign powers.

This article aims to conduct a techno-economic feasibility assessment of producing energy by waste incineration and methane capture in the central region of Mexico. Three scenarios at different efficiency rates were considered: 50, 80 and 100%. For the methane project, yields and power capacity were determined using the potential generation rate and the degradable organic carbon content through the LandGEM model. For incineration, the waste calorific potential and the average moisture content were used to estimate the achievable electrical performance. The estimated annual energy was 35,018 GWh for methane, compared to 537.71 GWh for incineration. Both projects reported financial economic feasibilities when evaluated at a discount rate of 12%. Incineration reported an net present value of US$49,942,534 and an internal rate of return of 26% in contrast to US$4,054,109 and 17% for the methane project. Although the payback period for incineration was lower than for methane, its levelized cost of energy was significantly higher. These results are intended to assist the decision-making process when planning and developing waste management strategies under principles of circular economy in Mexico and similar regions worldwide.

The relational perspective is a fundamental theoretical approach to understanding the actions of humans and organizations as they interact with others to survive. The concept of relational capital is used in management and strategic literature to highlight the importance of agents’ interdependence. This paper aims to identify the dimensions of relational capital and their variables within the intraorganizational context, analyzing the importance of organizational management. This is qualitative research. Participant observation, 27 face-to-face semi-structured interviews, and principles of grounded theory were used to collect and analyze qualitative data. By breaking down RC into a more comprehensive concept, this study offers clear evidence of the identification and definition of two-dimensional, multivariable relational capital. Although these two dimensions and their variables are analytically separate, in this research, it is recognized that, in fact, they are highly interrelated. The research can be beneficial for those interested in the improvement of our organizations and society through the development and maintenance of mutual gain relationships over time.

This article highlights the main aspects related to energy generation from biogas in a controlled landfill of Mexico City in order to determine profits and environmental benefits. The designed structures and public policies to provide waste management services in Mexico City have been exceeded. A significant increase in demand has led the government of Mexico City to base public services on rudimentary techniques using obsolete equipment. The modernization of waste disposal facilities and the diversification of services linked to waste treatment can offer several business opportunities to optimize energy generation from solid wastes. The use of landfills to dispose large amounts of waste enables the energy generation from biogas. The energy generated can diversify the electricity market and provide economic benefits to landfills managers to cover operational costs.
