Properties and Benefits of Biomass Briquetting of Macrophytes in Nansi Lake

Abstract

In order to provide a new technique for macrophytes use, this study evaluated the effect of biomass content on properties of biomass briquetting. Take lime as the binder, the best addition of biomass was 45%. In such case the drop strength of giant reed and reed briquetting reached maximum 55% and 74% respectively, and water impermeability reached minimum 15% and 7% respectively. Calorific value of biomass briquetting was between 11.1 MJ/kg and 14.9 MJ/kg and ash content was between 38.6% and 45.5%. Take giant reed briquetting as the example, 25% of money could be saved if briquetting replaced coal and people in Nansi Lake would get $159,333,333 a year. Also biomass briquetting could bring some environmental benefit including purifying water, slowing the greenhouse problems and acid rain. This study could provide a support for wetland restoration of the ecosystem, water quality, and the improvement of the economic benefits.
