    En América latina, la tasa de reciclaje es más baja que en Europa, esto se debe a la cultura adoptada por los europeos de la separación de materias primas. Para esto, se necesita una transformación tecnológica en países como Colombia, que tenga un impacto positivo para el medio ambiente. Por esto, el presente trabajo se circunscribe al estudio de la clasificación de desechos, donde se busca dar solución al problema de la separación de residuos en hogares, por ello, en la investigación se diseñó y construyó una máquina con la capacidad de separar materiales orgánicos de los no orgánicos con una eficiencia del 65%. La investigación se centró en la construcción de un prototipo de caneca de separación de residuos (la cual divide los residuos en orgánicos e inorgánicos), mediante sensores, microprocesadores y actuadores, estos captan, analizan y clasifican los residuos. El proyecto se inspiró en países como Suiza, donde se recicla el 99% de la basura, la fase principal en este modelo es la separación manual en los hogares.

    Delayed colorectal cancer care during covid-19 pandemic (decor-19). Global perspective from an international survey

    Background The widespread nature of coronavirus disease 2019 (COVID-19) has been unprecedented. We sought to analyze its global impact with a survey on colorectal cancer (CRC) care during the pandemic. Methods The impact of COVID-19 on preoperative assessment, elective surgery, and postoperative management of CRC patients was explored by a 35-item survey, which was distributed worldwide to members of surgical societies with an interest in CRC care. Respondents were divided into two comparator groups: 1) ‘delay’ group: CRC care affected by the pandemic; 2) ‘no delay’ group: unaltered CRC practice. Results A total of 1,051 respondents from 84 countries completed the survey. No substantial differences in demographics were found between the ‘delay’ (745, 70.9%) and ‘no delay’ (306, 29.1%) groups. Suspension of multidisciplinary team meetings, staff members quarantined or relocated to COVID-19 units, units fully dedicated to COVID-19 care, personal protective equipment not readily available were factors significantly associated to delays in endoscopy, radiology, surgery, histopathology and prolonged chemoradiation therapy-to-surgery intervals. In the ‘delay’ group, 48.9% of respondents reported a change in the initial surgical plan and 26.3% reported a shift from elective to urgent operations. Recovery of CRC care was associated with the status of the outbreak. Practicing in COVID-free units, no change in operative slots and staff members not relocated to COVID-19 units were statistically associated with unaltered CRC care in the ‘no delay’ group, while the geographical distribution was not. Conclusions Global changes in diagnostic and therapeutic CRC practices were evident. Changes were associated with differences in health-care delivery systems, hospital’s preparedness, resources availability, and local COVID-19 prevalence rather than geographical factors. Strategic planning is required to optimize CRC care
