Assessment of Soil Stabilization Properties Using Reused Printer Toner Ink: A Sustainable Perspective
Abstract
Improving the load-bearing strength of weak soils is a critical aspect of construction, and soil stabilization serves as a key method in achieving this goal. This research investigates the innovative use of waste printer toner ink as a stabilizing additive to enhance soil properties, particularly Unconfined Compressive Strength (UCS) and bearing capacity. Toner waste, often improperly discarded, presents environmental concerns; however, its sticky nature may contribute to better soil binding.
In this study, soil samples were prepared with toner ink additives at varying percentages 0%, 0.5%, 1%, 1.5%, 2%, 2.5%, and 3% and evaluated using UCS tests, Standard Proctor Compaction, and California Bearing Ratio (CBR) tests. The experimental results were compared with those of untreated soil. The inclusion of toner ink was found to enhance cohesion, compaction behavior, UCS, and CBR values, thereby increasing the soil’s load-bearing performance. The toner ink aids in bonding soil particles together, lowering permeability and improving compaction. However, higher concentrations beyond the optimum level were observed to reduce strength due to increased brittleness and reduced workability.
This investigation presents a sustainable solution for soil improvement using industrial waste, contributing both to environmental protection and geotechnical enhancement. The results point to the effectiveness of toner ink as a viable alternative soil stabilizer, with further studies recommended to assess long-term performance and ecological implications.
