Energy is a critical requirement for economic development and specifically to improve the conditions that influence all aspects of human welfare. However, the majority of people in developing countries have no access to reliable and affordable domestic energy sources. Development of organic material as sources of renewable energy through biomass, biogas, biofuel, bioreactor, algae fuel, biohydrogen, and so on, with better biotechnology by genetic improvement, environmental manipulation, purification, packing, compressing, are important for sustainable development. Biogas becomes one of the solutions to meet the energy need in rural areas of developing countries. However, the implementation of biogas has many challenges. Biogas produced from different biosources may contain pollutants that should be removed. The quality of biogas, represented by methane enrichment, can be improved with biogas purification technology. Removing the pollutants is recommended to avoid severe downstream damage and to increase the calorific value. This chapter discusses biogas purification.
