6. Usage of Fat

                Leftover fat, grease, or oil from restaurants that are thrown down drains, usually collect and cause clog sewage called “fatbergs”. London investigators discovered a 17-ton tower of fatbergs sitting around the sewers, which resulted on deeper research and tastings to discover other usages for these trashes.  As a result of the research starting in 2015 at Beckton, in East London, a sewage treatment plant will be powered by a mix of leftovers and fatbergs. All this useless trash will end up providing 130 million kilowatt hours of electricity a year.

                Fangfei Shen does not really give his personal opinion on what he thinks of the fatbergs, except his very last sentence in which it states, “Not a bad way to use up those leftovers”. This statement indicates that he thinks positively about the sewage treatment plant. In general Shen writes with an informative hand and tries to indicate some information about the good usage of trash. His system of writing flows and is not complicated, the reader does not stumble on sentences, though the names can be complicated to pronounce.
