25. FORMATION OF DIOXINS AND FURANS DURING MUNICIPAL SOLID WASTE GASIFICATION
Abstract Thermal treatment is an interesting strategy to dispose of municipal solid waste: it reduces the volume and weight of the material dumped in landfills and generates alternative energy. However, the process emits pollutants, such as dioxins and furans. The present study evaluated MSW gasification-combustion integrated technologies in terms of dioxin

26. Biodegradation of films of low density polyethylene (LDPE), poly(hydroxibutyrate-co-valerate) (PHBV), and LDPE/PHBV (70/30) blend with Paecilomyces variotii
The increased consumption of plastics in the world has been a subject of great concern and special attention by the scientific community. The aim is to promote development of materials that are biodegradable in a shorter time upon disposal in the environment. The most used synthetic plastics are difficult to biodegrade because they are made of long hydrocarb

27. Development and characterization of post-consumer rubber tire powder, high density polyethylene and ethylene-octene-1copolymer ternary mixtures
Scrap tires are considered a type of waste that litters landfills and the environment in general. Due to its chemically cross-linked structure, this material cannot be recycled by conventional processes because it does not melt. This work examined the production of polymeric composites using high density polyethylene (HDPE) filled with rubber tire powder (RT

28. Mechanical performance of concrete with incorporation of coarse waste from the marble industry
The waste resulting from marble extraction process is usually disposed of in landfills or dumps and its accumulation is causing serious environmental and landscaping problems. One way of reusing marble waste is to consider its incorporation in structural concrete as a non-primary aggregate. This research work attempts to alleviate the situation and provide i

29. Mechanical properties of recycled Kraft paper residue polyester composites
Construction industry has a significant grow in the past few years. Following that rate, the amount of residue produced from that growth also increases. The need to find alternatives apart from disposing that residue in landfills have led researchers to find new materials from disposal residues. In this paper, kraft paper from cement bags used in building co

30. Vibrational analysis of coconut fiber-PP composites
Many researchers have been studying coconut fibers due to its being a natural and renewable source. Moreover, coconut waste is discarded in landfills, bringing environmental problems because this material, although natural, takes time to be degraded. The use of natural fibers such as coconut fibers has become industrially attractive because of its low cost,

33. Análise de patentes de tecnologias relacionadas a resíduos de equipamentos elétricos e eletrônicos / Analysis of patents for technologies related to waste electrical and electronic equipment
The problem of solid waste has been touted as one of the most serious to date. The increasing scarcity of land for the establishment of new landfills, combined with the existing limitations for the recovery of non-renewable materials, low degree of implementation of new treatment alternatives and recycling, now represent a major challenge. Therefore, conside

35. AnÃlise do Fluxo de Gases na Camada de Cobertura do Aterro SanitÃrio Municipal Oeste de Caucaia (ASMOC) / Analysis of gas Flow in covering layer of Municipal Landfill West of Caucaia (ASMOC)
The growing human consumption entails a greater generation of waste, which, in turn, must be properly treated and disposed. The storage of waste in landfills produces gas, which if not managed properly will affect the quality of life. The uncontrolled emissions of these gases cause multiple economic, social and environmental impacts, as due to air pollution

36. The influence of soil and landfill leachate microorganisms in the degradation of PVC/PCL films cast from DMF
While the use of plastics continues to increase in our daily lives in a growing range products, these materials are very persistent in the environment. The blending of aliphatic polyesters with other thermoplastic polymers is a profitable way of producing materials with changed physical properties and biodegradability, which can facilitate microbial adhesion
