Iowa State Park Recycling Research Study, 2012

The Department of Natural Resources’ mission of “Leading Iowans in caring for our natural resources” provides the framework within which the Iowa State Park Recycling Research Study was conducted. Recycling at home and in places of business is becoming common for most Iowans but recycling is not available in any form at most Iowa State Parks. The Iowa State Park Recycling Research Study was undertaken to determine the amount of solid waste generated, primarily by campground guests, and how much of this waste is locally recyclable. The study also looked at existing solid waste hauling contracts and the location of area recycling centers. Based on data collected, recommendations are made regarding the economic and operational viability of implementing recycling in the eight (8) state parks participating in the study.

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.

Preparation and assessment of immobilized laccase-based micro- and nanocatalysts for the degradation of anthropogenic compounds

Since the dawn of its presence on earth, the human being has been able to exploit the enzymes for its subsistence. More recent is the meeting between the enzymatic processes and the urgent need for technologies that aim to preserve our planet. In this field nowadays enzymatic catalysis is tested either to depollution/remediation as well as waste disposal. The work presented in this thesis, regarding both these two topics, is tailored on two European projects (EU 2020), MADFORWATER and TERMINUS respectively. Firstly, production of micro- and nanocatalysts via immobilization of laccases (a lignin-degrader enzyme) is performed. In the second part of the thesis laccase is applied to a tertiary treatment of wastewater with the aim to degrade 9 pharmaceutical active compounds in batch reactors. Despite several optimizations, poor degradation is reached and we did not proceed with the study of different bioreactor setups. Therefore, the focus is moved to a project concerning the production of smart multi-layer plastic packaging containing enzymes to improve the possibilities of recycling. In this field shielded nanocatalysts produced via coating techniques able to interact with redox mediators are investigated. The target substrate in this second project is produced in laboratory (i.e. polyurethane like compounds), starting from monomers whose degradation had already been tested, as a proof of concept. The first enzyme studied is still the laccase.
