Use of LCA (life cycle assessment) in environmental sciences

The goal of this bachelor thesis is to describe the analytical method called the Life Cycle Assessment (LCA) and to show its practical applications in case studies especially in waste management. The LCA method consists of four phases. The first phase is the definition of the intention and volume of the study, which includes the subject, the recipient, the place concerned and the purpose of the study together with specifications of the scope of product system. The second phase deals with the life cycle inventory. The investigators collect the accessible data on individual inputs and outputs of the product system, which are consequently embedded into the inventory chart. The third phase applies to the assessment of the life cycle impact on predefined categories using the impact categories indicators. The final phase summarizes the interpretation of the life cycle, its intelligibility for the submitter being mainly considered
