Objective: Histology laboratories are resource-intensive environments that consume high levels of energy, rely on toxic chemicals, and produce substantial hazardous waste.This study aimed to evaluate sustainable alternatives that preserve scientific and diagnostic quality while minimizing ecological impact and enhancing occupational safety.Methods: A focused review of literature (2010-2024), international guidelines, and best-practice reports was conducted.Additionally, structured observations from routine histology workflows were integrated to assess applicability under daily laboratory conditions.Four domains were analyzed: chemical management, waste reduction, energy efficiency, and workplace safety.Results: Glyoxal Acid-Free fixatives emerged as viable replacements for formalin, reducing toxicity while maintaining morphological and molecular integrity.Xylene substitutes, including limonene-and alcohol-based solvents, demonstrated lower health hazards without compromising staining performance.Recycling strategies, such as paraffin repurposing and staining solution reuse, effectively decreased laboratory waste.Energy savings were achieved through high-efficiency instruments, automatic shut-off devices, and raising freezer settings from -80 C to -70 C, which reduced consumption.Targeted training programs fostered measur-able improvements in sustainable laboratory practices.Conclusion: Implementing green practices in histology laboratories can simultaneously reduce costs, improve safety, and lower environmental impact.By combining literature-based strategies with locally adaptable measures, laboratories can establish sustainable, eco-friendly, and resilient operational models.
