    Análisis de los beneficios ambientales, sociales y económicos resultantes de la formulación de un plan de gestión y aprovechamiento de residuos sólidos de la empresa Agrojar S.A.S.
    (2022) Carvajal Gil, María Luisa; Serna Cardozo, Evelyn Andrea; Celis Rivera, Paola Andrea
    Se realizó un estudio cuyo propósito fue analizar los impactos ambientales, sociales y económicos que se obtienen a partir de la implementación de un plan de gestión y aprovechamiento de los residuos sólidos en base a los diferentes procesos productivos que realiza la empresa Agrojar S.A.S. en las fincas de Gibraltar y la Guaca en el municipio de Jardín, donde se llevó a cabo una identificación, cualificación y cuantificación de los tipos de residuos que se generan allí, así mismo se plantean programas como la minimización y educación ambiental, además de proponer a la empresa desarrollar el fertilizante orgánico para uso comercial y comunitario. Se evidencia en los resultados que el aprovechamiento y valorización de residuos generados en una cadena de producción trae beneficios para empresa y su área de influencia, así mismo se encuentra que en las fincas de estudio cuando están en época de cosecha la cantidad de generación de residuos es mayor y se da un mal manejo por el hecho de contratar personal externo, mientras que en época de no cosecha solo se encuentran personal de planta ya capacitado en los aspectos del tema de manejo de residuos ayudando a que el impacto sea menor. Además, se pudo ver que no hay un aprovechamiento de los residuos orgánicos perdiendo la utilidad de estos. Por lo tanto, se concluye que la implementación de un plan de gestión integral de los residuos sólidos en una empresa es importante para demostrar su buena gestión respecto al tema de residuos.

    Aprovechamiento de los retales generados a partir de los procesos con láminas de acero al carbono, en la empresa Cortes y Perfiles LTDA
    (2018) López Cárdenas, Lina María; Cuervo Calle, Juliana
    This project focused on the use of leftovers generated in the transformation processes of carbon steel sheets, in the metalworking company Cortes y Perfiles LTDA, located in the industrial zone of Belén in Medellín. Said exploitation, sought to give a second chance to these remains, to reduce the environmental impact that is generated with emissions from both transport to different departments of Colombia, and its subsequent foundry. The utilization, materialized from the approach and later fulfillment of some objectives, these were: to recognize the physical and mechanical properties of carbon steel, the analysis of the transformation processes of steel sheets and the way in which this raw material is optimized in different companies; and finally, characterize the scrap and its possible applications according to the properties of the material and the machinery present in the company. The objectives were achieved, thanks to fieldwork and theoretical research, where conclusions emerged as: The most use steel sheet sizes from range cal 20 to cal 3/16, because they are the ones who buy the most and work in the company, others of the conclusions are: the different forms of remains, the weight of the remains according to the caliber and the alterations in the metal by the processes of transformation. The result of this project is a space divider formed mostly of carbon steel remains. It is also a piece that enters the market dynamics, competing in the area of home decoration and fashion, which is a strong and growing industry in the city of Medellín. This object is also an opportunity to generate a business idea, designed to be sold to a market segment, looking for unique, sustainable products with a high aesthetic content

    Caracterización de residuos sólidos en la cafetería de la Universidad de San Buenaventura Cartagena: propuesta de alternativas de uso con énfasis biotecnológico
    (2017-07-20) Ruiz Henao, María Jimena; Moncaleano Niño, Luisa
    Introduction. The problem of solid waste has become a global concern, which is why it is necessary to create strategies to improve the way they are prepared, through strategies that minimize the environmental impact. General objective. Characterize solid waste from the cafeteria of the University of San Buenaventura Cartagena, with the purpose of proposing alternatives of use with biotechnology emphasis. Methodology. Quantitative study of a cross - sectional prospective type, in which the coffee solid waste was characterized during a period of two months, where three random sampling were carried out for one week, using quarantine methods and volume - weight analysis. Results. In the cafeteria of the University of San Buenaventura Cartagena, during the first week of sampling a total of 188.5 kg / l of waste was generated and in the week two 411.6 kg / l. At the end of the two samplings, it was observed that 70% of solid wastes were classified as organic waste, 26% as recyclable waste and 4% as non-recyclable solids. Conclusions. The proposed alternative was to use as raw material and biotechnological potential the organic material generated in cafeterite. Through the characterization of all types of waste, the recovery capacity of each is evidenced; Which demonstrated that it is possible to carry out separation, collection and recycling processes..

    Caracterización fisicoquímica del sustrato agotado de Pleurotus ostreatus (orellana) y sus potencialidades agroindustriales
    (2016) Bejarano Bonilla, Juan Sebastian; González Ordoñez, Lina María
    In Colombia, there is a production of P. ostreatus, by the Smallholders, who work since 2007 in mushroom production "oyster type" in small facilities located on their farms. These productions are based on the use of waste resulting from the main agricultural activities in each area sugar cane being one of the most important since the sugar industry generates lots of bagasse as waste. However residues of post-harvest Orellana, what is typically known as "depleted substrate" not yet been sufficiently investigated to identify their agribusiness potential. This study aims to identify the physicochemical characteristics of Pleurotus ostreatus residues, in order to explore alternatives for later use. The variation of the nutritional characteristics of the substrate exhausted in producing Orellana, depend on the materials used for enrichment, as the initial substrate. The union of these two variables is reflected in the content of carbohydrates but not fat percentage, which depends more on the substrate of attachments.

    Propuesta de aprovechamiento de residuos de construcción y demolición (RCD) como fuente nutricional para suelos contaminados por pesticidas
    (2020) Corrales Vargas, Catalina; Morales Jiménez, Braulio Andrés; Jaramillo Florez, Maria Consuelo
    Construction and demolition waste (C&DW) is the result of urban growth such as concrete blocks,bricks, gypsum, porcelain, etc. Currently, urban development has become exponential, which hasled to increased construction and demolition activity, generatingthe inadequate disposal andaccumulation of waste from these activities, thus causing environmental and social problems,because about 57% of waste is not treated properly.Given the high use of soils for agriculture, various substances have been used to optimize resultsor to prevent and mitigate certain pests, such as pesticides. Commonly, to support plant growth,fertilizer has been used to nourish the soil, increasing the essential mineral nutrients for the plantsand also are involved in metabolic or structural functions, these minerals are C, H, O, N and Sbeing the main contributors of organic matter, P, B and Si that activate the defense system and ithas been evidenced the presence of minerals (Ca, Mg, Fe, Mn, Zn, Si, Al, and Na) in thecomposition of C&DW, which has led to the hypothesis of; if it would be possible to give themanother productive use and if it would be viable to apply them to the soil so that the plants assimilatethem and their nutrition is achieved.To make these nutrients moreaccessible to plants, it isnecessary to add a microorganism previously extracted from the C&DW to degrade it and disposeof the nutrients in the soil. The use of the pesticide INVETRINA 200 EC was evaluated as toxicto plants, since the proposal is based on the use of microorganisms and C&DW to nourishagricultural soils where this pesticide has been used.To determine the concentration of the pesticide to which plants are affected in their growth, anecotoxicity test was used, indicating then 4 concentrations of 2.75mg/L, 5.5 mg/L, 11mg/L and 22mg/l to determine the most lethal dose that for this case was 22 mg/L, although with the contractionof 2.75 mg/l it stimulated growth. It was determined that the existing microorganisms in theC&DW were Gram-positive bacteria, being specifically violet bacilli possibly capable of degradingthe C&DW, and from this it is proposed to use the composition C&DW+microorganism toimplement it as a nutritional source in the soils as a substitution to the commercial fertilizer, in thisway it would be reducing costs in agriculture and supporting the problem of soil degradation.
