Small Bioreactors for Management of Biodegradable Waste

  • Identifies the methods for producing the most energy from biodegradable waste by developing small bioreactors

  • Analyzes the design and operation of small bioreactors for producing biogas and compost

  • Determines the ratio of small bioreactor development cost to the obtained benefits via biogas output, energetic value and economic feasibility


About this book


This volume discusses how small bioreactors can produce useful biogas and compost from biodegradable waste. The authors identify which biodegradable wastes are optimal for small bioreactors, and how these choices can be used to increase bioreactor productivity. Additionally, readers will learn about how the amount and composition of biogas is estimated, the concentration of biodegradable waste that needs to be supplied to a bioreactor, the development of small bioreactors including the ratio of cost to the obtained benefits, and the nature of biodegradable wastes generated by both small farms and large food industry enterprises. 

The beginning chapters explain what biodegradable waste is, show how to predict how much waste an enterprise will produce, and elaborate the characteristics of the biogas which is generated from biodegradable waste in small bioreactors. Then the book discusses the types of small bioreactors and how to select the optimal bioreactor for a given case. Bioreactor performance is analyzed on both an economical and production efficiency basis, with experimental results provided on the quantity and quality of the biogas produced. The final chapters address how small bioreactors can be incorporated into small biogas plants, and the potential use of small bioreactors in countries with high demand for alternative energy using the case of Lithuania. The audience for this work includes specialists in biodegradable waste management and utilization enterprises, designers, and academics, researchers and students engaged in environmental engineering.
