AB  - Plastics, integral to various human activities, have led to a surge in 
      production, posing substantial challenges in waste management. The persistent 
      non-biodegradability of plastics, taking over a century to decompose, 
      necessitates exploration into technologies for their conversion into sustainable 
      fuels. Pyrolysis, an oxygen-free thermal decomposition process, emerges as a 
      promising avenue for producing liquid fuels from plastic waste. This study's 
      primary objective is to create and validate an Aspen Plus simulation model, 
      enabling techno-economic evaluation and sensitivity analysis of pyrolysis for 
      converting waste plastics into liquid fuels. Critical parameters-temperature, 
      retention time, and particle size-are examined for their impact on product yield 
      and quality. The methodology involves model development, validation, and 
      subsequent simulations with various waste plastic types under different pyrolysis 
      conditions. Experimental investigation using waste high-density polyethylene 
      (HDPE) in an auger reactor yielded an oil yield of 61.29%, char yield of 10.98%, 
      and syngas yield of 27.73% at 525  degrees C. Post-validation against this data, the 
      model explored four plastic types, revealing significant influences of plastic 
      type and reactor temperature on product yields. Polystyrene (PS) at 500  degrees C 
      produced the highest oil content at 83.69%, with temperature affecting yield 
      before secondary cracking. Techno-economic evaluation for a pyrolysis plant 
      processing 10,000 tons of waste HDPE annually indicated a minimum selling price 
      (MSP) of $302.50/ton, a net present value (NPV) of $12,594,659.7, and a 1.03-year 
      payback period. This study provides crucial insights for designing an 
      economically viable and sustainable pyrolysis process, guiding further research 
      and industrial implementation.
