Even though waste pickers play a crucial role in the urban solid waste management system in developing countries, their social, familial, and labor conditions remain uncertain. In this study, we analyzed the profiles of waste pickers in Colombia using multivariate statistical methods and cluster analysis. Our findings indicate that the majority of waste pickers have only completed elementary or high school education, and most of them are not associated with any organization and belong to the subsidized health regime. We identified five profiles of waste pickers in the population. The first consists of the most experienced individuals, while the second comprises individuals with the lowest salaries. The third includes older individuals who work more hours per day. The fourth is made up of individuals who work in the informal sector, and the fifth includes individuals who work in the formal sector. Our study highlights specific actions to be taken for each profile. Improving family and household conditions, social and educational status, and job conditions can have a significant impact on their lives.

“…Another cause is the phenomenon of consumerism. The acquisition of more goods, products, and services has contributed to an increase in the generation of waste [5]. Additionally, poor or nonexistent habits in the separation and disposal of waste contribute to the accumulation of garbage [6].…”

“…Managing solid waste presents a formidable challenge in the pursuit of sustainable energy security, and involves intricate socio-economic and cultural aspects. To achieve the goal of a circular economy (Nimita Jebaranjitham et al, 2022), a change from the "take-make-discard" philosophy to a "reduce-recycle-repair-reuse-share" approach is imperative. The waste hierarchy index tool, developed by (Pires & Martinho, 2019), is commonly utilized for enhancing the circular economy.…”

On a university campus, the diversity of types of waste is substantially relevant, as there are theoretical and practical classes, laboratory and field tests, maintenance of furniture, utensils and installations, in addition to a pulsating community that uses the campus space intensively for much of its day, including its food. In view of the above, this study aimed to carry out a qualitative and quantitative inventory of the solid waste generated on the premises of the Instituto Federal Goiano - Campus Rio Verde, using the methodological procedures suggested by NBR 10004/2004 with adaptations for the campus. Nine collection points were evaluated, listed from one to nine, three of which were voluntary drop-off points (PEVs), identified as 1, 5 and 7. The remaining six were distributed around the campus in areas close to laboratories and classrooms. The evaluation period ran from February to October 2022, with two monthly collections, always on days before the municipal public service's known collection times. The research was divided into two stages, the first of which was to apply questionnaires assessing consumption and waste generation, surveying the type of material generated, the frequency of disposal, the destination of this material and forms of packaging for segregation. This was followed by a gravimetric survey of nine identified and mapped collection points. The aim was to identify the profile of waste-producing agents, the amount generated, segregated and sent for recycling, what is sent to the municipal landfill and its possibility of recovery. A total of 5,008.34 kg of solid waste was collected, of which 23.4% was thermoplastics, 11.8% cardboard, 13% food waste, and 28.9% was collected at voluntary drop-off points by recycling cooperatives. The study also found that at points 2, 3, 6 and 8, the volumes of thermoplastics and cardboard are higher than those disposed of at the PEVs, demonstrating that although there is a perception of the importance of recycling, it is still deficient. projecting for one year based on the amount found, in the area used by the Campus, an amount of 0.22t/inhab/year of solid waste generation was obtained

“…Recent studies indicate that unattended solid waste at an open dumpsite can degenerate into serious health and environmental hazards [ [18] , [19] , [20] , [21] ]. A study indicates that about 2.01 billion tonnes of solid waste are generated all over the world annually, which is expected to grow to 2.2 billion tonnes by 2025 [ 22 ]. [ 2 ] describes waste management in developing nations, especially Nigeria as a wobbly one due to poor technical capacity and the high financial burden of waste management, supported by Ref.…”
