Gobernanza del espacio público: el comparendo ambiental en la UPZ 97 Chicó Lago 2014 - 2016.

La política del comparendo ambiental como herramienta pedagógica para el adecuado manejo de los residuos sólidos, pretende responsabilizar a la ciudadanía sobre el aseo del espacio público, en tanto la gestión por sí sola del Estado o las empresas privadas no ha logrado alcanzar este objetivo. El presente trabajo busca analizar, en el marco del servicio público domiciliario de aseo, la gestión del comparendo ambiental en el espacio público de la UPZ 97 Chicó Lago del 2014 al 2016, haciendo énfasis en las relaciones de los actores desde una perspectiva de gobernanza. De esa manera nos aproximamos a la noción de la ciudadanía frente al comparendo ambiental, para determinar cómo la política incluye su participación en la gestión del aseo en el espacio público.

Reciclaje de residuos sólidos domésticos y conductas pro-ambientales en una comunidad residencial de Bogotá, Colombia

Introducción: La implicación social dentro de la problemática ambiental, establece una relación causal entre hábitos e impacto ambiental; aspectos del comportamiento humano tales como la conveniencia, familiaridad, presión social y actitud, nos permiten realizar un acercamiento acerca de la decisión de reciclar o no en un hogar. Objetivo: identificar los factores ambientales asociados con el manejo de residuos domésticos entre los miembros de una comunidad residencial en la ciudad de Bogotá. Materiales y métodos: Se realizó un estudio transversal realizado a 200 personas de una comunidad residencial. La evaluación de la conducta pro-ambiental se llevó a cabo por medio de la utilización de la Escala del Comportamiento Pro-ambiental desarrollada por Corral-Verdugo unida a la escala de Reciclaje de Sidique. Para el tratamiento estadístico se empleó el análisis de regresión lineal múltiple. Resultados: La mayoría de los encuestados fueron hombres (55%), con una mediana de edad de 37,5 años. Más de la mitad tenía por lo menos formación en pregrado (53%), el 55,5% contaban con un empleo al momento de la entrevista, cerca del 50% de las personas refirieron tener casa propia y la mediana del tamaño de las mismas fue de 80 m2. De los aspectos sociodemográficos, el tipo de vivienda, sexo y edad, estuvieron relacionados con los factores ambientales pro reciclaje. Mientras que las conductas proambientales relacionadas fueron: altruismo, frugalidad, conducta ecológica general, indignación y aprecio por la naturaleza. Conclusiones: Las conductas proambientales Altruismo, Frugalidad, Conducta Ecológica, Indignación y Aprecio por lo natural, están relacionadas con la intención de reciclar. Para futuras investigaciones es necesario constatar la realización del comportamiento proambiental, para aseverar de manera irrebatible que las dimensiones analizadas pueden soportar una acción real y no un auto reporte de una conducta.

Synthetic polymers blend used in the production of high activated carbon for pesticides removals from liquid phase

For the activated carbon (AC) production, we used the most common industrial and consumer solid waste, namely polyethyleneterephthalate (PET), alone or blended with other synthetic polymer such polyacrylonitrile (PAN). By mixing PET, with PAN, an improvement in the yield of the AC production was found and the basic character and some textural and chemical properties were enhanced. The PET–PAN mixture was subjected to carbonisation, with a pyrolysis yield of 31.9%, between that obtained with PET (16.9%) or PAN (42.6%) separately. The AC revealed a high surface area (1400, 1230 and 1117 m2 g−1) and pore volume (0.46, 0.56 and 0.50 cm3 g−1), respectively, for PET, PAN and PET–PAN precursors. Selected ACs were successfully tested for 4- chloro-2-methylphenoxyacetic acid (MCPA) and diuron removal from the liquid phase, showing a higher adsorption capacity (1.7 and 1.2 mmol g−1, respectively, for MCPA and diuron) and good fits with the Langmuir (PET) and Freundlich equation (PAN and PET–PAN blend). With MCPA, the controlling factor to the adsorption capacity was the porous volume and the average pore size. Concerning diuron, the adsorption was controlled essentially by the external diffusion. A remarkable result is the use of different synthetic polymers wastes, as precursors for the production of carbon materials, with high potential application on the pesticides removals from the liquid phase.

Activated Carbons Produced from Mixtures of Synthetic Polymers by Physical and Chemical Activation: Application on MCPA Removal

The production of AC was achieved using the most common industrial and consumer solid waste, namely PET, alone or blended with other synthetic polymer such PAN. The PET-PAN mixture (1:1 W/W %) was subjected to carbonization, with a pyrolysis yield off 31.9%, between that obtained with PET (16.9%) or PAN (42.6%) separately. By mixing PET, as a raw material, with PAN (different ratio), an improvement in the final yield of the AC production, for the same activation time, with CO2, was found.

Production of activated carbons from single and mixtures of synthetic polymers

The production of activated carbons (ACs) involves two main steps: the carbonization of the carbonaceous of raw materials at temperatures below 1073 K in the absence of oxygen and the activation had realized at the temperature up to 1173 but the most useful temperature at 1073 K. In our study we used the most common industrial and consumer solid waste, namely PET, alone or blended with other synthetic polymer PAN. By mixing the two polymers in different ratios, an improvement of the yield of the AC production was found and some textural properties were enhanced by comparison with the AC prepared using each polymer separately. When all the samples were exposed through the carbonization process with a pyrolysis the mixture of PAN-PET (1:1w/w) yield around 31.9%, between that obtained with PET (16.9%) or PAN (42.6%) separately. The combine activation, with CO2 at 1073 K, allow ACs with a lower burn-off degree isothermally, when compared with those attained with PET or PAN alone, but with similarly chemicals or textural properties. The resultant ACs are microporous in their nature, as the activation time increase, the PET-PAN mixture AC are characterized by a better developed porous structure, when associated with the AC prepared from PAN. The AC prepared from PET-PAN mixture are characterized by basic surface characteristics, with a pHpzc around 10.5, which is an important characteristic for future applications on acidic pollutants removals from liquid or gaseous phase. In this study we had used the FTIR methods to determine the main functional groups in the surface of the activated carbons. The adsorbents prepared from PAN fibres presents an IR spectrum with similar characteristics to those obtained with PET wastes, but with fewer peaks and bands with less intensity, in particular for the PAN-8240 sample. This can be reflected by the stretching and deformation modes of NH bond in the range 3100 – 3300 cm-1 and 1520 – 1650 cm-1, respectively. Also, stretching mode associated to C–N, C=N, can contributed to the profile of IR spectrum around 1170 cm-1, 1585 – 1770 cm-1. And the TGA methods was used to study the loses of the precursors mass according to the excessive of the temperature. The results showed that, there were different decreasing of the mass of each precursors. PAN degradation started at almost 573 K and at 1073 K, PAN preserve more than 40% of the initial mass. PET degradation started at 650 K, but at 1073 K, it has lost 80% of the initial mass. However, the mixture of PET-PAN (1:1w/w) showed a thermogravimetric profile between the two polymers tested individually, with a final mass slightly less than 30%. From a chemical point of view, the carbonisation of PET mainly occurs in one step between 650 and 775 K.
