It was verified that the prediction of drying kinetics by Page and fraction order models were similar (modelling efficiency varying between the range of 0.917–0.995, varying the drying condition and wheat cultivar). Regarding antioxidant compounds for the three wheat cultivars, it can be seen that the higher fraction of ethanol (74.0% and 90.36%) used for extraction had greater process efficiency. Regarding the protein content in the three wheat cultivars, lower drying temperatures and intermittency periods result in lower quality losses of material (12.3% for BRS-Atobá wheat, 9.89% for BRS-Jacana wheat, and 18.71% for BRS-Sanhaço wheat). In terms of lipids, it was found that the influence of temperature was greater on the lipid content than on the protein content of the material (for the best drying condition, there were percentage decreases for the best condition of 36.16% for the BRS-Atobá wheat, 34.9% for BRS-Jacana, and 52.2% for BRS-Sanhaço).

Despite various available technologies, lead-acid batteries remain preferred for many industrial applications due to their inherent advantages. However, their expanded use necessitates proper waste management and recycling practices. During lead-acid battery recycling, Na₂SO₄ is generated as a waste product, which cannot be directly sold due to quality concerns and limited market demand. Consequently, advanced waste management techniques are required to comply with government regulations on industrial waste disposal. Despite these challenges, Na₂SO₄ serves as a vital precursor for producing K₂SO₄, a valuable fertilizer. Prior research on the glaserite process for converting Na₂SO₄ to K₂SO₄ has assumed Na₂SO₄ to be pure—without traces of impurities. However, Na₂SO₄ recovered from battery recycling contains various contaminants. To address this, HSC Chemistry software was used to model K₂SO₄ and NaCl production from impure Na₂SO₄ and KCl, considering feed impurities. Under ideal conditions—a 1 bar pressure, 25°C feed temperature, and 40°C reactor temperature—over 90% yield of K₂SO₄ and NaCl was achieved in the absence of impurities. However, the addition of impurities resulted in a reduction in yields. Notably, impurity levels ranging from 1% to 4% by weight still allowed for yields exceeding 90%. Furthermore, a review of reactor compositions revealed a significant depletion of potassium and chlorine ions which are crucial for K₂SO₄ and NaCl production as impurity levels varied from 0% to 10%.
