Accounting For The Environmental Impacts Associated With Residual Products In A Comparative Life Cycle Assessment Of Systems With Multiple Products, Yasuhiro Fukushima, Satoshi Ohara

Journal of Environmental Science and Sustainable Development

In many production systems, multiple products are interactively produced. Therefore, an innovative technology that leads to changes in parts of such systems may influence both the unit environmental impacts associated with the products, and the productivity of multiple products. To compare alternative technologies on a common basis, we often account for the avoided or supplemented emissions associated with the residual (i.e. surplus and supplemented) products produced from within the considered system boundary. In this study, using an example of an innovative technology envisioned for use in sugar mills, we first demonstrate how comparisons can be made when the systems vary …
