Worldwide, waste, a biomass, has the potential for solving future problems related to fossil fuel depletion and environmental problems. Waste conversion or extraction of values from waste can proceed in various ways. In recent times, various thermochemical and biological methodologies have been applied. Amongst all the thermochemical processes, pyrolysis is gaining importance because it can be conducted according to the coveted result. The recent investigation uses swine manure and goat manure as a waste resource. The recent investigation involves the simulation of the pyrolysis plant using the Aspen Plus® process simulation software. It can be inferred that the simulated results are incomparable range with the experimental results for the lab-scale. Then with the same designed model, feed rates of 1 ton/day (TPD), 2tons/day (TPD), and 3 tons/day (TPD) manure were utilized to obtain the production of pyro-products for pilot-plant-scale. The parametric sensitivity and optimization of the simulated model have been conducted using Design Expert®. It is observed that the minimum pyro-char production, maximum pyro-oil, and pyro-gas production is obtained at 0.679232 tons/day and 0.790000 tons/day for swine and goat manure, respectively, when the manure flowrates are 2.000000 tons/day at temperature 800 K for both the manures respectively.
