Sustainable Biogas Production from Distillery Wastewater

The distillery industry has a main contribution to the world economy. This is also important contributors to environmental degradation with the release of a large amount of wastewater. The wastewater of distilleries consists of very high concentration of BOD, COD, total solids, phosphate, sulfate, and different hazardous compounds. It causes serious environmental dilemma. A variety of physicochemicals and biological processes have been also researched for the safety of environment, human beings, and other living organism’s health. The prospective of biogas production from anaerobic digestion treatment process of distillery spent wash was also investigated. The anaerobic digestion needs less capital and production cost per unit in comparison to other renewable resources of energy, for example, hydro, sunlight, and wind. In addition, the potential of biogas toward electricity production is very economical. In addition, Sustainable Development Goals (SDGs) were achieved through biogas production. In the SDGs, nonetheless, the goal number seven initiates the need to employ efficient and sustainable renewable resources of energy to accomplish several global goals. The different precise objectives within SDG number 7 are such as considerably amplify the role of renewable energy sources to global energy matrix by 2030, boost up in the supply of contemporary and sustainable energy applications for all in emergent countries by expansion in infrastructure, enhance the energy efficiency improvement rate throughout the globe and technology up gradation. Biofuels from wastewater such as distilleries become the most advanced and efficient alternative energy source. These sustainable biofuels will be expected to play an important role in the quest of these above-mentioned goals. Energy is highly related with all of the other sustainable development goals, and recognition of these interconnections is significant to successfully execute them. It is now time to act in response to a historic agreement toward climate change solution in place. So the delivering on SDG7 is a foundation stone of that goal. On the other hand, if biofuels are anticipated to be fundamental in the recreation of sustainable development renewable energy goals in the discontinuation of fossil fuels generally on the basis of its environmental responsiveness, so this is the only prudent to evaluate how it completely merits its contemplation. However, the breakthroughs accomplished hitherto indicate that the future seems definitely bright and intense along with their power to generate a practicable neutral renewable energy resource from waste matter to sustain the comprehensive force toward the achievement of SDG number seven.
