Determination of pyrolysis and kinetics characteristics of chicken manure using thermogravimetric analysis coupled with particle swarm optimization

The valorization of chicken manure via pyrolysis can give biowaste a second life to generate value and contribute to the circular economy. In the present study, the thermal degradation and pyrolysis characteristics of chicken manure pyrolysis were investigated via thermogravimetric analyses (TGA) co...
