Abstract
Energy production and recycling from chicken manure (CM) is a sustainable and environmentally friendly approach. The CM is considered a valuable bioresource for methane production. The commercial applications of colimoxin for the poultry bird health; its traces are being ejected in CM and it becomes toxic for the methanogenic archaea during the anaerobic digestion process. The influences of the colimoxin were investigated on the anaerobic co-digestion performance of the CM and wheat straw (WS). The CM is co-digested with WS at carbon to nitrogen ratio of 25 to reduce the nitrogen contents of the CM. To optimize the colimoxin dose for methane generation; eight different colimoxin treatments were applied with varying colimoxin dose. The lower colimoxin dose was found healthy for the microbes and Treatment-4 resulted in 23% methane enhancement, while the higher colimoxin doses inhibited the methane production. The synergistic influences of the colimoxin dose on the volatile fatty acids generation and utilization were deeply monitored. The regression models were developed by using second degree polynomial regression models to optimize the colimoxin dose for the commercial biogas facilities and for the commercial poultry control sheds. The onsite methane generation would result in in-situ electrical energy production for the rural community.
期刊介绍:
Environment, Development and Sustainability is an international and multidisciplinary journal covering all aspects of the environmental impacts of socio-economic development. It is also concerned with the complex interactions which occur between development and environment, and its purpose is to seek ways and means for achieving sustainability in all human activities aimed at such development. The subject matter of the journal includes the following and related issues:
-mutual interactions among society, development and environment, and their implications for sustainable development
-technical, economic, ethical and philosophical aspects of sustainable development
-global sustainability - the obstacles and ways in which they could be overcome
-local and regional sustainability initiatives, their practical implementation, and relevance for use in a wider context
-development and application of indicators of sustainability
-development, verification, implementation and monitoring of policies for sustainable development
-sustainable use of land, water, energy and biological resources in development
-impacts of agriculture and forestry activities on soil and aquatic ecosystems and biodiversity
-effects of energy use and global climate change on development and sustainability
-impacts of population growth and human activities on food and other essential resources for development
-role of national and international agencies, and of international aid and trade arrangements in sustainable development
-social and cultural contexts of sustainable development
-role of education and public awareness in sustainable development
-role of political and economic instruments in sustainable development
-shortcomings of sustainable development and its alternatives.
