(1) Background: The importance of Zinc in today’s world can hardly be exaggerated—from anticorrosion properties, to its durability, aesthetic, and even medicinal uses—zinc is ever-present in our daily lives ever since its discovery in ancient times. The natural, essential, durable, and recyclable features of zinc make it a prized material with uses in many applications across a wide array of fields. The purpose of this study was to compare two life cycle impact assessments of zinc production by using two different main raw materials: (A) zinc concentrates (sulfide ore) and (B) Waelz oxides (obtained through recycling existing imperial smelting process furnace slags). The Waelz oxide scenario was based on a case study regarding the existing slag deposit located in Copsa Mica town, Sibiu county, Romania. (2) Methods: consequential life cycle impact assessment methods were applied to each built system, with real process data obtained from the case study enterprise. (3) Results: Overall, the use of slags in the Waelz kiln to produce zinc oxides for use in the production of zinc metal is beneficial to the environment in some areas (acidification, water, and terrestrial eutrophication), whereas in other areas it has a slightly larger impact (climate change, photochemical ozone formation, and ozone depletion). (4) Conclusions: The use of slags (considered a waste) is encouraged to produce zinc metal, where available. The results are not absolute, suggesting the further need for fine-tuning the input data and other process parameters.

Goal And Scope

Life Cycle Assessment (LCA) adalah salah satu cara yang dapat digunakan untuk mengevaluasi sistem pengelolaan sampah berdasarkan nilai potensi dampak yang dihasilkan. Bank Sampah Asoka Berseri di Kabupaten Tuban merupakan salah satu contoh unit pengolah sampah yang bertujuan untuk mengurangi potensi dampak dari timbulan sampah secara kualitas maupun kuantitas di wilayah pedesaan. Tujuan studi ini adalah menghitung dan mengevaluasi potensi dampak lingkungan yang dihasilkan dari program bank sampah, kemudian dibandingkan dengan penanganan sampah konvensional yang dilakukan oleh masyarakat. Metode yang digunakan berdasarkan CML Baseline v4.4 dan 14000 standar ISO, meliputi goal and scope, life cycle inventory (LCI), life cycle impact assessment (LCIA) dan interpretasi. Simulasi LCA dilakukan dengan Software OpenLCA untuk menghitung nilai potensi dampak dari setiap kilogram sampah yang dihasilkan. Berdasarkan hasil simulasi, setiap 1 kg sampah yang dikelola oleh bank sampah menghasilkan potensi dampak pemanasan global lebih rendah (6,395 kg CO2 eq.) dibandingkan dengan penimbunan (13,057 kg CO2 eq.) dan pembakaran (10,850 kg CO2 eq.). Pengolahan sampah lebih lanjut menjadi RDF dan kompos di bank sampah berpotensi menghasilkan dampak lingkungan lebih rendah dan menambah pendapatan masyarakat.

Life Cycle Impact

Land use is increasingly important for impact assessment in life cycle assessment (LCA). Its impacts on biodiversity and provision of ecosystem services are crucial to depict the environmental performance of products. Life cycle impact assessment (LCIA) models are commonly selected by consensus through processes frequently misinformed by the absence of practical application studies. Here, we performed an assessment of all free and peer-reviewed LCIA models for land use. We started with spatial correlation analysis at the country scale. Models that use the same indicators are strongly correlated, suggesting that regionalization is no longer a decisive issue in model selection. We applied these models in a case study for cattle production where feeds are replaced by sown biodiverse pastures (SBP). We tested (1) a non-regionalized inventory from an LCA database and, (2) a regionalized inventory that explicit considered the locations of land occupation and transformation. We found the same qualitative result: the installation of SBP avoids impacts due to feed substitution. Each hectare of SBP installed avoids the occupation of 0.5 hectares per year for feed ingredient production. Adding inventory regionalization for 70% of land use flows leads to a change of 15% in results, suggesting limited spatial differentiation between country-level characterization factors.
