The present thesis work entitled " Efficiency determination of the of the activated carbon obtained experimentally from the Alto Mayo agricultura} residues", it has been realized by the purpose of obtaining activated coal and hereby to give a value added to the agricultura} residues, since the raw material used for the obtaining of the final product they are: coconut rinds, coffee and cocoa. The project developed was explanatory type, where teams were used and materials available to the ecology faculty- Biology and Chemistry Laboratory. This work has as objective: to determine the efficiency of the activated carbon adsorption processes by means of the methylene blue solution. For it the analysis of the characteristics became initially physicist - chemistry of the samples ( dampness %, fixed carbon %, total ashes %, porosity % and volatile matter % ). In addition analysis was carried out ...

The proper management of municipal solid waste is decisive due to its environmental impact. In Yurimaguas, a Program of Source Segregation and Selective Collection of Municipal Solid Waste was implemented to promote sustainable waste management practices. However, it is necessary to understand user satisfaction and its relationship with service quality. The objective of this study was to establish the relationship between the quality of the service Program of Source Segregation and Selective Collection of Municipal Solid Waste and the level of user satisfaction in Yurimaguas. Non- experimental, correlational, cross-sectional and quantitative research. The sample consisted of 109 heads of households in the program. Non- probabilistic unique sampling was used. A questionnaire with a Likert scale was applied, with a Cronbach's coefficient greater than 0.89 for both variables. The majority r...
