Gestão de resíduos sólidos em condomínio vertical: Possibilidades e desafios

Abstract

The environmental crisis in which today's society finds itself arises from the perception about natural resources and the development model adopted by the humanity, which drives the mankind towards a more intense consumption, with the generation and destination of solid waste from human processes, making it a great burden on the support threshold of the planet. This work aimed to present a proposal that could guide the management of solid waste generated by a vertical residential condominium in Campina Grande-PB, offering viable solutions from a technical, social and environmental point of view, enabling the adequate disposal of recyclable solid waste and reducing the amount of non- recyclable solid waste sent to the landfill. The execution of the project was based on gravimetric characterization, which indicated the proportion of solid waste discarded by the condominium (12% of dry recyclables, 52% of wet recyclables and 36% of non-recyclable waste). After that, the socioeconomic characterization and the environmental perception of the residents were verified, which guided the development of Environmental Education strategies aimed at the mobilization and sensitization of the condominiums, who became participants in the execution of the selective collection. Among the strategies, an application for mobile devices was developed, aimed at the dissemination of information and as a motivation for residents and service providers. Equipment was designed and supplied to favour the separation of the solid waste generated, being these collectors for intraresidential, intracondominial and extracondominial use. Gravimetric characterization carried out after the implantation of the selective collection pointed that there was reduction in the amount of non-recyclable solid waste (23%) and increased the amount of recyclable solid waste (77%). It was concluded that the use of Environmental Education strategies sensitized and mobilized the residents, so that their participation promoted a series of environmental gains, such as favouring the work of collectors of recyclable materials, increasing the economic potential of solid recyclable waste and providing the reduction of negative impacts by the disposal of materials whose proper treatment and disposal could be carried out.
