Life cycle assessment of various algae technology: A case study

It is known that environmental problems in our world and life are mostly caused by fossil fuel consumption. Issues such as global climate change, seasonal warming and narrowing of cooling periods have started to affect our daily life negatively in the world. This book chapter is intended to provide a methodical solution to these problems. In the recent COVID-19 outbreak, the spread of a virus infected by a bat species in a way that threatens human life also reveals that we do not exist in the world, that is, different living species from us are a determining factor in our lives. Like the famous physicist Einstein's word above. Life cycle assessment (LCA) became popular in the early nineties. This technique was initially considered as a direct marketing tool used during the environmental impact assessment of the whole production or the comparison of the two production stages. In the following periods, it was understood that the more effective results of this method were put forward not only as a marketing tool. Therefore, LCA application is important because it can be applied to all production methods. Especially in recent years, this method has started to be expressed as a critical method in environmental policies. The concept of integrated product policy is a prime example of this. Not only the European Union but also China and the United States are developing strategies that support this method as an important key. The attractiveness of this method is increasing day by day as the world's top 500 companies conduct sustainability reporting in their operations, especially in terms of LCA. In this study, firstly, we showed about fossil fuel power plants, and then we gave information about algae technology about the retention of flue gas in the atmosphere and lastly, the life cycle assessment for energy systems was evaluated to make flue gas to be less harmful to the environment.
