“…The scientific literature includes few studies carried out in countries of the Latin American environment. An analysis of solid waste generation in Colombia [58] was based on gross domestic product (GDP). This analysis compared GDP in Colombia with that of countries such as Brazil and Bolivia, highlighting the inverse relationship between GDP and solid waste generation.…”

For the first time in the scientific literature, this research shows an analysis of the implementation of circular economy techniques under sustainable development framework in six municipalities with a depressed economy in Colombia. The analysis is based on solid waste data production at a local scale, the valuation of the waste for subsequent recycling, and the identification and quantification of the variables associated with the treatment and final disposal of waste, in accordance with the Colombian regulatory framework. Waste generation data are obtained considering three different scenarios, in which a comparison between the simulated values and those established in the management plans are compared. Important differences have been identified between the waste management programs of each municipality, specifically regarding the components of waste collection, transportation and disposal, participation of environmental reclaimers, and potential use of materials. These differences are fundamentally associated with the different administrative processes considered for each individual municipality. This research is a good starting point for the development of waste management models based on circular economy techniques, through the subsequent implementation of an office tool in depressed regions such as those studied.

“…This article provides an overview of the efficiency and challenges of incorporating thermoelectric heat recovery systems, made with economic thermoelectric cells marketed in Latin America, when evaluated at the laboratory level (under controlled conditions) and at an industrial level (under uncontrollable conditions). The project is part of a local strategy to improve material circularity [35,36] and energy optimization [37][38][39] in materials and industrial processes in the country, which are issues which have been considered important for decades at the legislative and technological levels. The case study presented here is applicable elsewhere, and is a particularly inexpensive and green solution, feasible to run in developing countries where generation cells are difficult to obtain.…”

Thermoelectric Generator Using Low-Cost Thermoelectric Modules for Low-Temperature Waste Heat Recovery

et al. 2023

One of the most significant problems in industrial processes is the loss of energy according to the sort of heat. Thermoelectrics are a promising alternative to recovering this type of thermal energy, as they can convert heat into electricity, improving the industrial efficiency of the process. This article presents the characteristics of low-cost thermoelectric modules typically used for generation (SP1848-27145SA (TEG-GEN)) and refrigeration (TEC1-12706 (TEC-REF)), both utilized in this research for heat recovery. The modules were evaluated against various configurations, source distances, and distributed systems in order to determine optimal recovery conditions. The experiments were conducted both at the laboratory level and in a large-scale furnace of the traditional ceramics industry, and they revealed that even refrigeration modules are suitable for energy recovery, particularly in developing countries, whereas other generators are more expensive and difficult to obtain. These thermoelectric generators were tested for low-temperature heat recovery in regular furnaces, and the results are to be implemented elsewhere. Results show that even the thermoelectric refrigeration modules can be a solution for heat recovery in many heat sources, which would be particularly strategic for developing countries.

“…Moreover, preventive strategies such as improved economic models must be developed. The popular circular economy model [11,12] has been implemented in many sectors, e.g., by modifying manufacturing and design processes so that products last longer and can be used in other applications after their lifecycles (upcycling). For this reason, many sectors that involve materials and electronic devices are now experiencing a revolution, with processes being redesigned to fit the circular economy model [13], for example, in additive manufacturing [14], construction and building materials [15], smart materials [16], thermoelectric modules [17], and the transportation industry [18].…”

This paper presents the results of research into construction and demolition (C&D) waste in Colombia. The data and analyses are shown in a local and Latin American context. As the situation in Colombia is quite similar to that in many developing countries worldwide, this research and its findings are potentially applicable to similar economies. Several factors were calculated and compared in order to evaluate which best fit the data from Colombia. We also included an experimental characterization and analysis of several key types of C&D waste from important infrastructure projects in Colombia, specifically by using the X-ray diffraction and scanning electron microscopy techniques. For the quantification of CDW, a calculation was performed based on the area and four factors of volume and density, followed by an econometric analysis of the detailed information using the Hodrick–Prescott filter, which revealed the CDW trends. Our results revealed that there are limitations regarding the availability of information and effective treatments for this waste, as well as shortcomings in education and other issues, not only for Colombia but also for other countries in Latin America.
