“…Accordingly, with the humidity results presented, the absence of leachate in the composting process would be expected. This was confirmed in this study when a TCB or composter barrel was used, and confirmed by other authors [16][17][18]20]. This is explained owing to the high temperatures developed during the composting process (54-60 • C, Table 2) and because the composting was conducted in open systems, which reduced the excess humidity.…”

“…However, these TCBs were fed by household food waste and processed in a backyard. Considering the latter results in comparison to those reported here for the Chemistry Department, for example, a TCB for 31 persons processed 0.59 kg day −1 , it could be expected that a TCB located in a workplace could perform well for around 80 people if one TCB could receive 1.5 kg day −1 , as reported by Campos-Rodríguez et al [18].…”

“…For example, Abushammala et al [16] and Saad et al [17] obtained peak temperatures of 50 • C ( Table 2). Campos-Rodríguez et al [18] also reported lower peak temperatures (53 • C) when using mountain soil microorganisms. The above demonstrates that the organic matter decomposition by Takakura EMs has a greater magnitude [31] than that achieved by the application of fruit or mountain EMs.…”

“…These amounts were well below the maximum processing capacity that each TCB was designed for (1.2 kg day −1 ). Campos-Rodríguez et al [18] and Borrero [20] reported food waste loadings of 1.5 kg day −1 TCB −1 and 1.35 kg day −1 TCB −1 using the same type of TCB and substrate. However, these TCBs were fed by household food waste and processed in a backyard.…”

“…Campos-Rodríguez [18] evaluated a degrading substrate with mountain microorganisms (based on forest mulch) and another degrading substrate, and compared these with Takakura microorganisms in composting food waste methods adopted by restaurants at the Costa Rica Institute of Technology (ITCR in Spanish). The Takakura substrate was more efficient in reducing the volume of the residues [18].…”

The Takakura technique converts food waste into compost. This project explored the potential use of composting in offices and workplaces. The method involves using small boxes containing a fermentation substrate where food waste is added. Two Takakura composting boxes (TCBs) were placed in the kitchens of the Chemistry Department and the Environmental Engineering buildings at the Instituto Tecnológico de Costa Rica, Costa Rica. Food waste from both buildings, comprising the food waste of 45 staff members, were composted from June to December 2015. All types of food, except grease, oil, raw meat, and bones, were processed. The mass and volume of food added to the boxes were quantified daily. A chemical analysis of the compost was also performed. A speech was given to educate the staff members about the system. A survey, before and after the speech, was developed to evaluate the knowledge and tolerance towards composting in closed spaces. A total mass of 88.29 kg, equivalent to 232 L of residues, was processed, from which 17.37 kg (37 L) of compost was obtained. This represented a mass and volume reduction of 80% and 84%, respectively. Compost analysis gave a C/N ratio of 14.7/1, indicative of maturity. Most of the staff members (92%) agreed to the separation of waste at the source. However, 37% suggested allocating the box outside the building. The survey, after the speech, showed that educating staff is necessary before installing boxes at a workplace.

ResumenLa acumulación y falta de aprovechamiento de los residuos orgánicos (RO) que produce el complejo Paloquemao del SENA, planteó la necesidad de tratarlos por medio de la obtención de abono orgánico. Para ello se planteó un proceso de tratamiento de tres fases: 1) cuantificación de los residuos mediante cuarteos periódicos durante el 2017 en las unidades de almacenamiento, determinando una tasa de generación de 2,20 t/mes. 2) Diseño e instalación de una planta piloto industrializada, aprovechando tres mezclas entre café, fruta, verdura cruda y aserrín, con la modificación de dos técnicas tradicionales, debido a las bajas temperaturas que presenta Bogotá (entre 8 y 20 ºC), que interrumpe el proceso de compostaje modular a los 20 días de degradación de materia orgánica en su primera fase mesófila y que acondiciona así el material para someterlo a vermicompostaje para un total de 32 días de procesamiento, lo cual refleja una disminución significativa del tiempo de producción de abono con respecto a las aplicaciones convencionales y una capacidad de producción de hasta 628 kg. 3) Análisis de variables como C/N con una relación de 14:1 para la mezcla 2, lo que demuestra que es un abono enriquecido según la NTC 5167 (2011).Palabras clave: residuo, orgánico, físico-químico, biodegradación, Eisenia foetida, SENA. AbstractThe accumulation and lack of use of organic waste (O.W) produced on Paloquemao SENA Complex, raised the need to treat it by organic compost. Therefore, three methodological phases were developed, 1) O.W quantification on storage units by periodic quarters during 2017, producing a rate 2,20 T/Month. 2) Design and installation of an industrialized pilot plant, taking advantage of the organic waste obtained by three mixtures based on coffee, fruit, raw vegetables and sawdust, implementing modifications on two traditional techniques due to Bogota's low temperatures (between 8 & 20°C), causing an interruption on the modular composting cycle after 20 days of the O.W degradation on mesophilic phase and conditioning obtained material to vermicomposting up to 32 days of process, which reflects a significant difference on fertilizer time production regarding to conventional applications, obtaining a production capacity of 628 kg. 3) variables as C/N were analyzed with a relation of 14:1 for mixture 2, which proves that it is an enriched fertilizer according to NTC 5167 (2011).
