This paper estimated the domestic waste cooking oil (DWCO) generation for the city of Guayaquil, Ecuador. The study also determined how social indicators influence the quantity of waste produced domestically by using Ordinary Least Square (OLS) regression. For this effect, a stratified random sampling methodology was used, resulting in the selection of 441 sample households for this study. Results show that the city produces 5.11 grams of DWCO per capita every day also, households with higher number of youngsters between 12 and 18 years old produce more DWCO and social status plays a crucial role in liquid waste generation, giving a negative coefficient for the OLS regression, meaning that households with higher social status produce less of this waste. Finally, this study suggests new insights concerning the generation of domestic waste cooking oil and sets a milestone for future research in the reuse and recycle of this liquid residue.
Influence of social indicators in the consumption of domestic electricity for urban marginal areas of Guayaquil
(LACCEI Inc., 2020-07) Hidalgo, José; Mendieta, Nadia; Caamaño, Luis; Founes, Johanna; Garcés, Laura; Terán, Fabiola; Crespo, Tania
The current study examines the influence of social indicators on the consumption of electricity for eight urban marginal areas of the city if Guayaquil, by means of ordinary least square regression. For this purpose, domestic and electric indicators were obtained from the literature and after correlated with the natural log of average monthly electricity consumption. Results show that labor gives a negative coefficient, meaning that people work outside the home and that households with more women and elderly people consume more electricity.
The Determinants of Household Electricity Demand in Marginal Ecuador: “A Case Study at Monte Sinai”
(LACCEI Inc., 2018-09) Hidalgo, José; Coello, Silvia; González, Yomar
Electricity demand has grown in almost 75% in the last ten years, and with the addition of 900 thousand new families from rural and marginal areas to the electricity grid, total electricity demand may increase significantly. The understanding of the specific energy consumption patterns of these sectors could explain the influence on the electricity demand and lead the regional government policy to promote their formal electricity access. However, micro level analysis may show different correlations among determinants than those usually reported in previous macro models. The data was taken from a convenience sample of 190 socio-economic surveys at Monte Sinai in order to obtain a system of electricity demand equations and elasticity using Tobit regression model.
Waste to Energy Potential of Domestic Waste Cooking Oil in Guayaquil: A review.
(LACCEI Inc., 2020-07) Hidalgo, José; Coello, Silvia; Crespo, Tania; Amaya, Jorge; Soto, Manuel; Jervis, Freddy; Moreira, Cesar
This paper examines the opportunity for waste cooking oil as a potential source of energy by means of (i) production of biodiesel, (ii) direct burning and (iii) biodegradation. It offers a profound review of existing literature and it measures possible uses of the waste cooking oil produced in the city of Guayaquil. In addition, important chemical and physical properties are presented after the development of a sampling process for after laboratory testing. Conclusions show that the most suitable technology is biodiesel generation, followed by biodegradation, but direct burning is found to be not a possible solution due to its kinematic viscosity.
