Life cycle in rice processing in Pelotas-RS
Rice is a cereal of great importance for human consumption. The industrialization of this grain has a high impacting potential and therefore the research was carried out aiming to identify the sector with the greatest polluting potential using the Life Cycle Assessment as a methodology verifying the balance of specific inputs and outputs of rice grain processing. For this, openLCA 1.10.2 software was used, fed with secondary data from the “Ecoinvent 3.6 apos unit” database and its method package, choosing within it the CML 2001 model containing the impact categories to be analyzed. For complete data modeling, the Life Cycle Inventory built from the grouping of activities was also inserted, forming and characterizing the processing inputs and outputs, with primary data, for three process areas: Sector 1-Reception, Sector 2-Processing and Sector 3-Packaging. For the production of 1 bale of white rice, this being the considered functional unit. In the Life Cycle Impact Assessment in rice processing, 6 categories of impacts were obtained that received greater contributions from the process. As a main conclusion, it appears that the activities analyzed are potential contributors to the six categories analyzed, these received 100% of contributions from the process, and as a result of the contribution of the activities grouped by sectors, it was concluded that the greatest impact potential is on Sector 1, with 72.2%, and then on Sector 2, with 23.9%, with the highest energy consumption and generation of the most waste. bulky and not used in the process.
