El objetivo de esta investigación fue analizar el uso de residuos agroindustriales del plátano como sustituto de feldespato para el desarrollo de baldosas cerámicas que cumplan con la Norma Técnica Colombiana - NTC 919. Para ello, se diseñaron probetas con diversas mezclas en harinas y cenizas del residuo agroindustrial y otras con la fórmula cerámica convencional (muestra patrón). En todas las mezclas se determinó las propiedades físico-cerámicas y densidad. La mezcla alternativa que mejor resultado mostró se continuó analizando con Fluorescencia de Rayos X (FRX), Difracción de Rayos X (DRX) y Microscopia por Barrido Electrónico (SEM, por sus siglas en ingles). Las propiedades físico-cerámicas evidenciaron una mejor aptitud en las probetas preparadas con 5% de harina de cascara de plátano. Los análisis del FRX muestran un predominio del silicio y el aluminio, probablemente asociado a la mullita, según el DRX; lo anterior, también se pudo observar en las imágenes por microscopia. Los resultados de los análisis revelan un producto con una calidad dentro lo permitido por la norma NTC 919.

This study analyzes the operation of Biomass System (BIO System) technology for the combustion of pellets from almond and olive trees within the circular economy model. Its aims are the reduction of greenhouse gas emissions as well as waste removal and its energy use by reintroducing that waste into the production process as technological nutrient. In order to do so, combustion efficiency under optimal conditions at nominal power was analyzed. In addition, a TESTO 350-XL analyzer was employed to measure CO and NOx emissions. High combustion efficiency values were obtained, 87.7% and 86.3%, for pellets from olive tree and almond tree, respectively. The results of CO and NOx emission levels were very satisfactory. Under conditions close to nominal power, CO emission levels were 225.3 ppm at 6% O2 for pellet from almond tree and 351.6 ppm at 6% O2 for pellet from olive tree. Regarding NOx emissions, the values were 365.8 ppm at 6% O2 and 333.2 ppm at 6% O2 for pellets from almond tree and olive tree, respectively. In general, these values were below those legally established by current legislation in European countries. Therefore, BIO System technology is a perfectly feasible option in terms of energy use and circular economy.

Proposal to foster sustainability through circular economy based engineering: a profiteble chain from waste management to tunnel lighting

molina, valentin | 2017-12-02

The increasing demands of infrastructures in terms of energy consumption, raw material demand, greenhouse gas emissions, waste management, treatment of components after their lifetime period, and financial costs are nowadays a serious threat for sustainability. Given that the resources are limited, it is difficult to ensure an accurate level of well-being for future generations. For this reason, new perspectives in design, production and consumption are necessary. In this work, the principles of circular economy are applied to concrete branches of engineering. Departing from a design orientated to new uses after life period of infrastructures, a circular economy-aimed engineering makes possible the connection and mutual profit of such different branches like waste management and tunnel lighting. The benefits in environmental and financial terms are a strong argument in favor of a stronger link between engineering and circular economy.
