“…Hence, in recent years the characteristics of the MSW of the Cuenca canton, presented 60.91% organic matter, amongst others, as detailed in Table 3. Likewise, the ILM Consortium performed the characterization of the MSW of the Las Iguanas landfill in 2012, 2016 and 2017, which, depending on the economic conditions, established five groups with per capita production (PPC) of 0.87 (kg/inhab/day) conditions: economic low, medium-low 0.96 (kg inhab/day), medium 0.98 (kg/inhab/day), medium-high 1.27 (kg/inhab/day) and high 1.56 (kg/inhab/day) [9,36]. Therefore, the characterization conducted in 2017 indicates 67% organic matter, amongst others, as detailed in Table 4.…”

The landfill is a final disposal technique to confine municipal solid waste (MSW), where organic matter is degraded generating leachate and biogas composed of methane gases (CH4), carbon dioxide (CO2) and other gases that contribute to global warming. The objective of the current research was to estimate the amount of biogas generated through the LandGEM 3.03 mathematical model to determine the amount of electrical energy generated and the number of homes that would be supplied with electrical energy from 2021 to 2144. As a result of the application, it was estimated that in the Pichacay landfill, the highest point of biogas generation in 2053 would be 76,982,177 (m3/year) that would generate 81,226,339.36 (kWh/year), and would supply 5083 homes with electricity. Similarly, in the Las Iguanas landfill, the highest point would be 693,975,228 (m3/year) of biogas that produces 73,223,5296.7 (kWh/year) and would supply electricity to 45,825 homes. Of the performed gas analyses in the Pichacay landfill in 2020, an average of 51.49% CH4, 40.35% CO2, 1.75% O2 and 17.8% H2S was presented, while in the Las Iguanas landfill, for 2020 and 2021, we obtained an average of 51.88/CH4, 36.62% CO2, 1.01% O2 and 187.58 ppm H2S. Finally, the biogas generated by being harnessed minimizes the impacts related to global warming and climate change and would contribute electricity to the nearby communities.

“…There is no legal framework to promote the exploitation of solid wastes for the development of waste-to-energy power plants. Nevertheless, some research has been performed [22]. Regarding liquid biofuels, during 2010, the Ecopaís program was launched to start the distribution of a 10% ethanol/gasoline blend in Guayaquil city.…”

Prospects for Bioenergy Development Potential from Dedicated Energy Crops in Ecuador: An Agroecological Zoning Study

et al. 2023

View full text Add to dashboard Cite

Most climate change mitigation scenarios rely on the incremental use of biomass as energy feedstock. Therefore, increasing the share of alternative sustainable energy sources as biomass is crucial to provide both peak and base electricity loads in future scenarios. The bioenergy potential of Ecuador has been addressed for agricultural by-products but not for dedicated bioenergy crops. Agricultural zoning studies have been developed for food crops but not for energy crops. Currently, the bioenergy share of electricity produced in Ecuador (1.4%) comes mainly from the use of sugar cane bagasse from sugar production. This study aims to identify potential sustainable bioenergy resources for continental Ecuador using agroecological zoning methodologies and considerations regarding land management, food security, in-direct land use change and ecological and climate change risks. The results identified 222,060.71 ha available to grow dedicated bioenergy crops and potential electricity production of 8603 GWh/year; giant reed ranks first with a potential net energy yield of 4024 GWh per year, and Manabí province presents the highest potential with 3768 GWh/year. Large-scale deployment of bioenergy in Ecuador would require the study of sustainability considerations of each project. The species studied are traditional bioenergy crops; research on novel species is encouraged.

“…An alternative that has been the subject of numerous investigations is the use of WCO as a second-generation raw material to produce biodiesel. Its use has been demonstrated to reduce the negative environmental impact inherent to the process, as it is a raw material that does not require a stage of cultivation or extraction (Foteinis et al, 2020), (Amaya et al, 2020) and (Viornery et al, 2020). Recycling cooking oil for biodiesel production is an example of a sustainable action that, well organized, could satisfy the criteria for green circular economic activity in the context of promoting a continuous reduction of the environmental impacts using low CO2 emissions energy.…”

In recent years, society has achieved a better quality of life; this has been possible thanks to scientific and technological advances. Among the advances that have allowed us to move forward is, without a doubt, the development of the vaccine against the SARS-CoV-2 virus. The method used for the synthesis of this vaccine was developed by Ugur Sahin and Öezlem Türeci, founders of BioNTech. Yes, behind the scientific development of greatest impact and relevance in recent years are a man and a woman. This scientific development was possible thanks to both of them, and here it is important to highlight the quality of women in science related to seeing issues from another perspective. Therefore, the union of their strengths and their differences made it possible to have a vaccine that makes it possible to return to life without confinement, without fear of going out, and with the possibility of enjoying it. Thus, the role of women in science is not only valuable, but fundamental to solve the problems that afflict us today. In this context, I can only thank and congratulate the women who today, thanks to their training, discipline and commitment, are giving us this wonderful work of science. I am sure that more challenges will come, but always counting on them, we will come out ahead. My most sincere appreciation and admiration.
