Environmental Impact of End-of-Life Tires: Life Cycle Assessment Comparison of Three Scenarios from a Case Study in Valle Del Cauca, Colombia

2017

Life Cycle Assessment methodology has been applied to estimate diverse environmental impacts of different usage alternatives for worn-out tires at the end of their useful life in a case study at the Department of Valle del Cauca, Colombia. Different real scenarios were compared, which allowed for the assessment of the best environmental option for the management of worn-out tires. A method developed in the Institute of Environmental Sciences at University of Leiden, better known as CML-2001, was used to calculate the environmental impact indicators. The results show that the incineration of whole tires in cement plants, and the activities of grinding and floor manufacturing from granulated rubber, exhibited the best indicators, especially in terms of environmental load avoidance through the recovery of materials. Finally, the categories of depletion of the ozone layer, acidification, global warming potential, depletion of abiotic resources, and photochemical ozone formation revealed that the strongest environmental impacts are associated with retreading and the production of multipart asphalt. This is due to the use of synthetic rubber in the former alternative, and of liquid asphalt, gravel, and diesel consumption in the latter.

“…Liamsanguan and Gheewala, (2008) applied a LCA to municipal solid waste management systems to identify the overall environmental burdens and to assess the potential environmental impacts for a number of different technologies. Wittmaier et al (2009) assessed emissions from different options for thermal treatment and energy recovery from waste in a region in Northern Germany using the LCA approach, and De Feo and Malvano, (2009) focused in their LCA on incineration, final landfilling, and recycling issues. Soares et al (2013) performed a thorough LCA and cost analysis for microwave, autoclave, and lime disinfection technologies and also assessed their environmental impact (see also section below).…”

Microwave as an emerging technology for the treatment of biohazardous waste: A mini-review

Microwave is an emerging technology to treat biohazardous waste, including material from healthcare facilities. A screen of the peerreviewed literature shows that only limited information may be found in this area of work and, furthermore, analysis of the references reveals that sometimes not all necessary aspects for the appropriate use of the technology are considered. Very often conventional microwave technology is applied for the inactivation of pathogens, which might make sense for certain applications but, on the other hand, may lead to the misbelief that microwave systems cannot be used for the inactivation of a solid "dry" waste. However, conventional microwave units have no means to control the inactivation process, and especially moisture content. But there are a few sophisticated microwave technologies with appropriate measurements allowing a validated inactivation of biohazardous materials. These technologies are an effective tool for inactivation and some of them are commercially available. It must also be considered that the waste should be preferably inactivated either directly at the place where it is generated or biohazardous waste should be transported only in closed systems. Moreover, microwave technology presents a possibility to save energy costs in comparison to the more widely used autoclaves. This mini-review will discuss important aspects for the use of microwave technology for the treatment of biohazardous waste.

Municipal Solid Waste in Goiás (Brazil): Current Scenario and Projections for the Future

2017

View full text Add to dashboard Cite

The production of municipal solid waste (MSW) has increased annually worldwide. This situation can be verified in the municipalities of Brazil, that produce more MSW and have difficulty in managing their waste resulting in harmful consequences for the environment and ecosystems. For instance, in the State of Goiás, most of the produced MSW are sent to dumps. In this context, the goal of this study was to create a projection for the amount of MSW that will be generated in each of the 246 municipalities of Goiás by 2040. To do so, a population projection from 2015 to 2040 was done, alongside its correspondent MSW production and identification of the current MSW managing systems in the State. Results show that, by 2040, Goiás will have more than 8.7 million inhabitants, 32% more than 2015. However, 88% of the municipalities will continue to have less than 50 thousand inhabitants. The municipalities of bigger dimension, on the other hand, will be concentrated mainly in the Goiânia Metropolitan area and surroundings of the Federal District regions. In terms of MSW production, an increase of about 35% in waste generation is estimated for 2040 when compared to 2015. In 2040, the Goiânia Metropolitan, surroundings of the Federal District and the Southwest regions of Goiás will produce 70% of the State MSW. Regarding the produced MSW technological routes, in 2015 about 70% of the State waste went to either unlicensed landfills or dumps, while 8% did not even get collected, having ended up in wastelands or waterways. Considering this panorama in Goiás, what will be the management of MSW in 2040 if nothing is done?
