Earth and Environmental Sciences: Life Cycle Assessment of Processes and Products

Life Cycle Assessment (LCA) plays an essential part in estimating the environmental impact of new technologies and methods. LCA is a methodology to analyze and compare various products and technologies considering their environmental effects along the whole life cycle, i.e. from the subtraction of raw materials until the end-of-life of a product. LCA helps to determine which product has the most negligible environmental impact over others by assessing the effects of products and processes throughout their lifecycle.

At an initial stage of a novel technology process, it is fundamental to recognize the environmental burdens. Calculating the effects when assessing a new technology is demanding, as the number of possible results can be enormous. More than two-thirds parts of the final expenses and effects on the environment are based on decisions that are made in the initial development phase of the technology. For this reason, it is extremely important to study technologies' environmental effects even before they are put into practice.

In this collection, we welcome articles focusing on the life cycle assessment of various products or processes. It can be a single evaluation or a comparison of different methods. The frame of the research can be any version, e.g., gate-to-gate, cradle-to-gate or cradle-to-grave analyses. We are also open to new research directions and/or combining LCA with economic and energy factors.
