December 31, 2025December 31, 2024
Supplies$217,028$200,905
Oil and oil related products123,883152,992
Solvent and solutions11,58912,458
Other19,58818,302
Total inventories and supplies$372,088$384,657

Oil and oil related products inventory has decreased due to lower volumes of oil inventory on hand at December 31, 2025 when compared with December 31, 2024 and overall cost decreases for the oil inventory. Supplies inventories consist primarily of critical spare parts to support the Company’s incinerator and re-refinery operations and other general supplies used in normal day-to-day operations. Stocking crucial spare parts, largely for the sustained functioning of the Company’s incinerator facilities, has resulted in a rise in the supplies inventory balance. Other inventories consist primarily of parts washer components, cleaning fluids, absorbents and automotive fluids, such as windshield washer fluid and antifreeze.
