A significant contributor to the waste streams nowadays are domestic plastics. However, in Ecuador most of them end up in the local landfills impacting the environment in a major form. The aim of this paper is to classify and quantify the total amount of household plastics generated for the city of Guayaquil. To obtain this, we developed a novel methodology with the help of students from a local university. Each household produces approximately 1.64 kg of plastics daily. From all plastic waste, PET occupies the 1st place as the most disposed of with approximately 44%, followed by HDPE with 20% and PP with 10%.

Because the high infectious rates of Coronavirus in south countries, the compliance with prevention guidelines (WHO and Ecuadorian Emergency Committee (COE) prevention guidelines) is necessary to prevent the spread of the virus. People ignoring instructions likely exacerbating the social, economic, and environmental concerns about the pandemic. According to sociodemographic descriptors in urban and rural areas of Guayaquil, average falls to over 70% for people having only below upper secondary education and over 50% for employed people among 20-34 years old, in the middle of a popular economy weakened context. The risk perception (F2), safety climate (F3) and the perceived understanding (F4) are believed to directly influence the compliance (F1) within this context. The mediating role of perceived understanding and safety on compliance response is also considered. This study aimed to identify factors that make an Ecuadorian population more/less likely to comply infectious COE guidelines. The data was collected after the last COVID-19 lockdown in Guayaquil city via online survey of 927 participants. The SPSS®Amos 27.0 - SEM based on maximum likelihood estimation was implemented to evaluate all the considered hypotheses (χ2 /df=3.6, CFI ≥ 0.91, TLI ≥ 0.90, RMSEA ≤ 0.05). The analysis of this hypothesis suggests that positive change in compliance is possible mediating the effect of risk positively. The study leaded to factors affecting a fully restrictions compliance after the last regulation in Guayaquil City (April-May 2021): the self-awareness of following the rules seems to have a strong relationship with perception of having enough knowledge about the coronavirus to primarily leads the behavioral control. Low confidence about government management during crisis events is another factor that enhance non-preventive behavior. This combination seems to be enough to decide about the convenience of following health precautions, especially during period of relaxation.

In order to deal with global warming and climate change through the smart management of natural resources and waste elimination for the conservation of the environment, this study aims to evaluate the behavior of household`s residents towards electricity and water consumption and solid waste generation (HSW). The paper also intends to correlate this behavior with socioeconomic indicators, such as: household size, level of education, income generation, labor force and social status. This study relied on 2593 random stratified questionnaires who live in the city of Guayaquil. The findings revealed that different socioeconomic groups houses demonstrate the same tendency in the sustainable consumption attitudes of electricity of water. Subsequently, the findings also ascertained differences are found in the possession of ecological devices. HSEG possess more these kinds of devices than LSEG. Therefore, government strategies should be set in motion to make households more aware of the level of pollution they produce and the inefficacy of their consumption of resources.

This paper estimated the household solid waste (HSW) generation and composition in Guayaquil, Ecuador. The study also determined the socio-economic factors influencing the waste generation of the households in the city by using Ordinary Least Square (OLS) regression. For this effect, a stratified random sampling methodology was used, resulting in the selection of 665 sample households for this study. The applied methodology resulted in a composition of HSW: organic waste (72,6%), plastic (8,7%), glass (2,4%), metals (1,7%), paper and cardboard (6,6%),fabrics (2,5%), dust and ashes (2,9%) and other residues, such as hazardous and electronics (2,6%). This study suggests new insights concerning the role of socioeconomic characteristics and its effects in the generation of household waste and waste composition in Guayaquil, Ecuador.
