“…The first one includes anaerobic digestion and fermentation, while the second includes combustion, pyrolysis, and gasification [13,14]. However, the majority of waste-to-energy (WtE) facilities are focused on thermal treatment technologies and particularly on combustion processes [10]. MSW that cannot be recycled or landfilled can be used as a fuel in waste to energy facilities.…”

“…WtE protects the land, as one unit of 1 × 10 6 ton/y requires for the total systems around 10 ha (0.1 km 2 ), with an operational lifetime of 30 years, while the equal amount of wastes 30 × 10 6 ton requires around 300 ha (3 km 2 ). An upgrade of the unit (same area) will allow an additional 30-year operation [10]. There are several pathways to recover energy from non-recyclable wastes and from the composting and recycling residues.…”

Transforming Waste to Wealth, Achieving Circular Economy

Wastes are usually thought of as unwanted or unusable materials. Waste is any substance which is discarded after primary use, or considered worthless, defective, and of no use. The term is often subjective, as not every application has identical raw material requirements and sometimes even objectively inaccurate. A starting point towards managing waste is the division in basic categories, ranging from municipal and agricultural waste to radioactive and explosive waste. Through proper collection of municipal solid waste, very important metals and other valuable sources can be recovered and used in new products, thus achieving significantly lower production cost and environmental impact. Success stories in waste management are reported in countries around the world. These typically showcase optimal waste transformation to wealth. Furthermore, applied waste management methods are specified. These actions should be adapted by every organization handling waste. At a managerial level, these must be considered as potential resources, commodities with significant economic, environmental and sociological added value. This paper attempts to identify and present the valuable resources and products that exist in waste streams, focusing mainly on their monetary value, based on data recovered from literature and raw materials stock markets. Municipal solid waste and non-hazardous commercial and industrial wastes are considered in this context. The methodology followed was based on identification and analysis of cities-communities and countries that have successfully adopted waste management policies towards circular economy and waste to wealth transformation.

“…This has led to an increase of heavy metals from e-waste in soil, sediments and water. Therefore, appropriate control measures are needed for the generation and disposal of e-waste [14][15][16]. Appropriate remediation techniques are also needed to reduce pollutants in e-waste, especially metals in e-waste.…”

“…Each remedy has advantages and disadvantages compared to other alternatives. The best remediation technique depends largely on the contaminated area, concentration of contaminants and other considerations [16][17][18]. The development of a new treatment technique is currently a major problem for researchers, so new hybrid techniques are constantly being developed and more research is needed in the future to achieve optimal results.…”

A serious problem that arose with the evolution of modern industry is generation of electrical and electronic equipment waste. In the last decades, the generation of electronic waste has increased a lot and it is estimated that in 2030, almost 74 tons of electronic waste will be generated, which will represent a significant threat to the environment. The purpose of this article is to track the potential impacts on the environment, to highlight the importance of waste management strategies and to provide the latest information in the field. A presentation of the countermeasures that must be taken at the national and international level to address the sensitive problem of waste management is also realized.

“…A recuperação de metais de fluxos de REEE é uma forma de implementação de padrões circulares para os recursos finitos presentes neste tipo de resíduo (OTTONI et al, 2020;SAHLE-DEMESSIE et al, 2021). Os recursos extraídos de resíduos eletrônicos podem substituir com sucesso as matérias-primas primárias (OESTREICHER et al, 2020;XAVIER et al, 2021).…”
