ELI Advanced Academic Skills Summer 2013: Week 2 Blog Response

Probably, the incineration will extend for many countries around the world as this technology show good advantages for big cities. This kind of city generally own difficult to find specific land for final disposal of solid waste. Furthermore, the land prices closed to these cities are too expensive. However, the large and medium-sized cities represent less than 20% of the world cities. The most are small cities under 20 thousand habitants that don't own financial conditions for operate an incinerator or contact some company. Other problem is that the small cities don't provide qualified manpower to operate safely these facilities. However, these cities own land enough to construct landfills. In Brazil, for example, it's possible construct small-sized landfill with security without the set up of soil protective membrane. In these cases is possible to compact the base of landfill using clay. Moreover, the installation of incinerators represent a great problem in poor and development countries, because the proper equipments to treatment of gases are very expensives and generally aren't installed them like should to be. The local environmental agencies, in its turns, don't get control and oversight every time the environmental quality in these facilities as there is lack of trained people and equipment of air quality measurement. So, It's unfeasible to use incinerators in many places around the world. Both the final disposal systems show vantages and advantages, and need to be analysed under different angles.
