This work explores the feasibility of producing alternative fuel through the pyrolysis of syringe waste (SW) and saline bottle waste (SBW). Plastic-derived medical refuse poses serious environmental and public health risks when mishandled. Laboratory runs were performed in a batch-type fixed-bed reactor, varying temperatures from 0 to 600°C at 50°C increments. The influence of temperature on product formation was examined. Key attributes of pyrolytic oil from SW and SBW—including density, kinematic viscosity, pour point, boiling point, and cloud point—were assessed. The measured ranges were 726–758 kg/m³, 3.19–4.75 cSt, −12 to −16°C, 86–95°C, −2 to −5°C, and the GCV remained close to 42–44 MJ/kg. Char exhibited a GCV of about 42–43 MJ/kg. GC-MS and FT-IR outcomes indicated elevated levels of alcohols and organosilicon compounds in oils derived from SW and SBW, respectively. TGA-DTG profiles revealed that thermal decomposition of these oils occurred primarily between 50–280°C. With adequate post-treatment, both liquid and solid fractions can function as energy sources or chemical intermediates for numerous sectors. The findings also demonstrate similarities to low-grade liquid fuels and high-quality solid fuels. The surge in medical waste during and after COVID-19 has produced significant disposal challenges. Pyrolyzing syringes and saline bottle waste can help mitigate pollution while offering a supplementary energy route.
