“…the composting of organic solid waste (88%) and the recycling of dry solid waste (86%) were the MSW treatment alternatives recommended by the experts, followed by the disposal in the landfill (83%), as recommended by other Brazilian authors [23], [24]. Composting of organic matter was considered the most suitable technology for the treatment of solid waste in Mumbai, india, according to the opinion of a panel of experts, applying the delphi method [15].…”

“…therefore, the creation of inter-municipal Consortium reached a consensus of 77% of the specialists, as a way to make possible the installation and operation of more sanitary landfills in the amazon and, thus, to optimize the final disposition and economic sustainability of the associated municipalities, due to the possibility of apportioning the costs involved in the administration and operation, optimizing financial resources and investment in technologies of environmental control and leachate treatment [27]. in addition, the landfill is the least costly alternative to any other technology option for MSW treatment, such as recycling, incineration and bio-methanization [21], [24].…”

“…incineration technology has been widely adopted in developed countries; however, a significant portion of specialists (80%) have not recommended this alternative for the management of MSW in the Southwestern Brazilian amazon because of the relatively higher cost compared to other treatment technologies [21], [24]. Moreover, it requires a daily production of waste (240 t day -1 ) achieved only in the metropolitan regions of Manaus (aM) and Belém (Pa) [4].…”

“…Humaitá city generates about 4,070 t year -1 of MSW (0.41 kg day -1 per inhabitant), consisting of 47% organic waste, 40% recyclable waste (paper, plastic, metals, long-life packaging and glass) and 13% other non-recyclable materials [24].…”

the amazon is facing challenges for solid waste management, due to its social, environmental and economic vulnerabilities. the main goal of this research was to investigate barriers of integrated municipal solid waste (MSW) management for the amazon, applying the delphi method. a consultation with waste management experts allowed raising the main alternatives recommended for that geographical region. in addition, in loco surveys evaluated the MSW management of three cities from Southwest Brazilian amazon (SWBraM): Humaitá and Manicoré, in the state of amazonas (aM), and ariquemes, in the state of rondônia (rO), Brazil. a total of 35 experts responded to the consultation, and there was unanimity that the prevention of solid waste generation should be encouraged in the amazon. there was a consensus on the treatment of MSW in the amazon: composting of organic waste (88%) and recycling of dry waste (86%), in addition to the disposal of MSW in landfills (83%). the municipalities of Humaitá and Manicoré collect and dispose MSW in dumps. However, in Manicoré, there is a recyclable Material Collectors Cooperative that diverts about 3.0 t month-1 of recyclable waste from the dump. ariquemes disposes its MSW in the only sanitary landfill of SWBraM, which receives about 135 t day-1 of the MSW generated in the 14 municipalities that form an inter-municipal Consortium. the main challenges raised for the MSW management in the amazon were as follows: investments in preventing MSW generation; supporting the creation of Cooperatives and the social inclusion of waste collectors; improving and integrating the river and road modals; creating conditions for the commerce of materials in Manaus recycling market; and supporting the creation of inter-municipal Consortium for landfill construction and operation.

“…Brazil's contrasts show the difficulties of the North region regarding shared responsibility, reverse logistics and circular economy. Paes et al [29] suggested that the lack of logistic structure and the low industrialisation in this region explain the higher percentages of recyclable waste (paper, plastic and metal) disposed of in landfills or open dumpsites.…”

Circular Economy and Solid Waste Management: Challenges and Opportunities in Brazil

Brazil has a vast territory and regional diversity, which turn the promotion of circular economy (or its improvement) into a complex challenge. This paper aims to analyse these challenges and solid waste management opportunities as a driving force for the circular economy in Brazil. Therefore, two significant challenges are discussed in this paper: increasing industrial waste recovery and improving the selective collection of municipal solid waste. Industries are concentrated in the country's South and Southeast regions, where 56% of the population live and where the best logistic infrastructure is also located. These features can help the circular economy related to industrial and municipal solid waste in those regions but bring challenges concerning the waste generated in the other part, such as the Brazilian Amazon. According to legislation, the productive sector is responsible for its products before and after use (waste prevention actions). One of the national laws establishes reverse logistic systems for several items, such as agrochemical packaging and electrical and electronic waste, but some sectors have better results than others in terms of circular economy. The cement industry in Brazil is highlighted as a case of relative success. On the other hand, the mining industry in Brazil has challenges related to the large amount of waste generated with high environmental and social risks, which caused several large accidents in the last years.
