M-GRCT: A Dynamic Circular Economy Model for the Optimal Design of Waste Management Systems in Low-Income Municipalities

Abstract

This article introduces M-GRCT, a circular economy decision support model for the design of recyclable waste management systems in low-income municipalities. The model allows for performing calculations on a set of two scenarios integrating a sociocultural dynamics assessment, this being a characteristic feature of this type of municipalities. The model also integrates the analysis of the remaining variables usually addressed in solid waste management schemes while considering topics such as reduction of the carbon footprint due to activities such as the transport of recyclable waste, the generation of leachates, the generation of greenhouse gases and the promotion of an increase in the number of associated recyclers and selective routes. The economic evaluation of the different implementation scenarios is supported by a dynamic tool called DATA4 (a macro-type array accompanied by two control panels programmed in Visual Basic and dashboards by Power BI). M-GRCT constitutes a tool for the promotion of good environmental practices and the identification of strategies for the promotion of local development mechanisms. Results provided by the model contrast with those obtained by traditional linear economy approaches. An illustrative example of the application of the M-GRCT model is shown. The model was used to simulate the municipal solid waste managing system of the municipality of Guateque (Colombia). The results show the importance of integrating both economic and environmental costs to optimally allocate governmental and private resources when the recycling rate is expected to increase in the next 10 years.

Implementing Circular Economy Techniques for the Optimal Management of Recyclable Solid Waste Using the M-GRCT Decision Support Model

“…This research was conducted using M-GRCT [23], a dynamic circular economy model for the optimal design of waste management systems in low-income municipalities. Based on the conceptualization of the M-GRCT circular economy model, the DATA4 computer tool was developed.…”

“…The economic viability criteria of the M-GRCT model [23] were built from two waste management business models. The first model was defined considering a linear waste management strategy, in which the operation consists of a waste collection system and final landfilling without obtaining recycled materials.…”

“…When implementing circular economy models, it is necessary to determine the sector to which they are applicable in order to determine the relationships and associations that are essential for these circular models to work. Currently, there are circular economy models in many different fields, such as the economies of developing countries [16], agriculture and livestock [17], wastewater [18], tires [19], industrial processes [20], biomethane [21,22] or waste management [23], among others.…”

Environmental impact of a design for a solid waste plant in the Francisco Morales Bermúdez market

“…Un diseño de manejo de residuos sólidos de fábricas, junto con la capacitación de la ciudad de Shahroud, Irán, se basó en analizar los residuos sólidos cuantitativa y cualitativamente, el resultado fue la eficaz aplicación de la economía circular, por lo que los desechos regresan al ciclo de producción además de reducir la tasa de eliminación de estos [18]. Por otro lado, se elaboró un modelo de gestión de residuos sólidos basado en la economía circular, es aplicable para mejorar la gestión de municipalidades de bajos ingresos, los impactos positivos de este diseño es la reducción de lixiviados y gases de efecto invernadero, además de contribuir a la reducción de la degradación de suelos y la generación de empleo de las comunidades locales [19].…”
