5. 4. Explorative Scenarios for Future Lithium Supplies and Demand

   University essay from Uppsala universitet/Institutionen för geovetenskaper

   Author : Aksel Rahman; [2023]
   Keywords : lithium mining; lithium future production; Gompertz models; Richards models; Logistic models;

   Abstract : Because of its specific qualities, lithium is a key element for making lithium-ion batteries, which is of great relevance since the battery sector is the fastest growing user of lithium to date and with the transition towards a fully electrified transportation sector due to the current climate agenda and an even bigger increase in demand for lithium is anticipated for the coming decades. The two main sources for lithium to date are mines and brines, with brine water composing around 87 % of the world’s lithium reserves in terms of contained lithium. READ MORE

6. 5. INVESTIGATING THE TOXIC AND ACIDIFYING EFFECT OF SCRUBBER EFFLUENT ON STRONGYLOCENTROTUS DROEBACHIENSIS LARVAE

   University essay from Göteborgs universitet / Instiutionen för biologi och miljövetenskap

   Author : Ida Vartia; [2022-09-28]
   Keywords : ;

   Abstract : To meet the new environmental requirements of reduced sulfur emissions from ships, many shipowners have installed an open-loop scrubber to clean the exhaust. In this scrubbing process, seawater is pumped from the ocean and combined with the emission gas, creating an acidic and toxic effluent that is directly discharged into the ocean, potentially damaging the marine environment.
