“…This process focuses particularly on heterogeneous plastics that are pretreated, or polluted, and cannot be reused efficiently by any other process. Thermal recycling of plastic waste occurs in thermal recycling plants using combustion chambers, incinerators, boilers, or large industrial plants [148][149][150]. These provide a convenient energy production option, due to the high calorific value of plastics-7375 Kcal/Kg, compared to urban solid waste, which is 3450 Kcal/Kg [151]-comparable to common fuels [113,152].…”

Waste from information technology (IT) and telecommunication equipment (WITTE) constitutes a significant fraction of waste from electrical and electronic equipment (WEEE). The presence of rare metals and hazardous materials (e.g., heavy metals or flame retardants) makes the necessary recycling procedures difficult and expensive. Important efforts are being made for Waste Printed Circuit Board (WPCB) recycling because, even if they only amount to 5-10% of the WITTE weight, they constitute up to 80% of the recovered value. This paper summarizes the recycling techniques applicable to WPCBs. In the first part, dismantling and mechanical recycling techniques are presented. Within the frame of electro-mechanical separation technology, the chain process of shredding, washing, and sieving, followed by one or a combination of magnetic, eddy current, corona electrostatic, triboelectrostatic, or gravity separation techniques, is presented. The chemical and electrochemical processes are of utmost importance for the fine separation of metals coming from complex equipment such as WPCBs. Thermal recycling techniques such as pyrolysis and thermal treatment are presented as complementary solutions for achieving both an extra separation stage and thermal energy. As the recycling processes of WPCBs require adequate, efficient, and ecological recycling techniques, the aim of this survey is to identify and highlight the most important ones. Due to the high economic value of the resulting raw materials relative to the WPCBs' weight and composition, their recycling represents both a necessary environmental protection action, as well as an economic opportunity.

“…However, there might be issues with technology transference and scalability in Guayatá (G1). The daily waste production capacity in that population is way below the one reported by other processes worldwide [19], [50]- [53]. Although Andes produces a low amount of waste with 45,184 inhabitants, its population and waste generation are expected to grow.…”

“…Currently, these municipalities produce 17.62 and 225 T of waste/day. The study in [19] revealed that, above 100 T/day, incineration can be implemented by means of a circulating fluidized bed. This technology is already being commercialized and can be adapted to SW with low calorific value.…”

This study estimates the electric energy production potential from municipal solid waste in Colombia. The Colombian municipalities of Pasto (Department of Nariño), Andes (Antioquia) and Guayatá (Boyacá) were selected as representative populations of the national context because of their socioeconomic and demographic features, as well as the public availability of their waste management plans. The technical characteristics of two conversion technologies were analyzed: incineration (thermal conversion) and anaerobic digestion (biological conversion). From a technical point of view, the results showed that anaerobic digestion is feasible in all three scenarios, while incineration is viable in Pasto and Andes.

“…Waste to Energy (WTE) is the sustainable approach to generate energy (electricity) by utilizing municipal solid waste. Reuse of waste products to recover energy in the form of electricity or heat is the most appropriate method to solve the waste problem [17]. Waste to energy is the source of renewable energy which is economical, feasible and eco-friendly [18,19].…”

In the span of past few decades, population, urbanization and industrialization have transformed the mankind living standard and dynamics of the nature. Certainly, energy is the basic need for all living organisms. Energy is the route towards the economic growth. The evidence shows that the countries faced with energy crises are left behind in the economic activities; as a result, people are deprived. This study reviewed the available renewable energy resources and potential with positive and negative aspects. This study comprehensively discusses the renewable macro and micro energy resources studied in the past two decades reported in various studies. The paper is divided into two sections; the first section discusses the energy produced in the macro level and the second section discusses the energy produced using different strategies and techniques in the micro level. The potential and positive outcomes of the energy resources were identified. New paradigm of micro energies and importance of reusing the available resource of micro energy using different resources like energy harvesting on the road surface, vibration, airflow, radio frequency and thermal energy etc. were discussed. Lastly, the study focus does not only review but also finds the potential and opportunities for the researchers in the future to utilize the renewable energy resources.
