Abstract

There is widespread concern that increasing concentrations of carbon dioxide and other greenhouse gases in the earth's atmosphere will ultimately lead to climate changes. Recognizing the important role that fossil fuels have in the economies and lifestyles of people throughout the world, it is reasonable to ask if the global economy can be powered in ways that might have less impact on the environment because they discharge less carbon dioxide. A way of addressing this sensitive issue could be through the biodevelopment of biowaste as an alternative and renewable energy resource. Landfilling and incineration are popular ways to deal with biowaste but both cause negative environmental effects such as the use of valuable land and production of dangerous gases. The structural components of cells, cellulose and hemicellulose, make biowaste very susceptible for bioproduct development and biowaste offers biotechnology an opportunity to assist in maintaining environmental quality.

摘要

人们普遍担心,地球大气中二氧化碳和其他温室气体浓度的增加最终将导致气候变化。鉴于化石燃料在全球各地人们的经济和生活方式中所起的重要作用,人们有理由问,全球经济能否以对环境影响较小的方式提供动力,因为这些方式排放的二氧化碳较少。解决这一敏感问题的一种方法可能是通过将生物废弃物进行生物开发,使其成为一种替代和可再生能源。填埋和焚烧是处理生物废弃物的常用方法,但两者都会造成负面的环境影响,如占用宝贵土地和产生危险气体。细胞的结构成分纤维素和半纤维素,使得生物废弃物非常适合用于生物产品开发,生物废弃物为生物技术提供了一个有助于维持环境质量的机会。
