Food wastes are generated massively across global food supply chains. Conventional treatments of food waste (e.g.,
landfilling and incineration) could cause environmental, economic and social problems. Valorization of food waste
into value-added chemicals is a more sustainable and cost-effective option. This paper investigates the slow pyrolysis
as an environmentally friendly and efficient way to thermo-chemically conversion of food waste into value-added
products. TGA-DTG study of slow pyrolysis of dried Goji berry pulp (GBP) samples was carried out at different
heating rates. To establish pyrolysis mechanism, two kinetic approaches were used for determination of kinetic
parameters: first, which involves using model-free methods and second, the use of iso-kinetic relationship analysis to
identify the low and high-temperature kinetic regimes during the chemical transformation of the investigated material.
It was shown that iso-kinetic temperature (363.79 °C) represents a transi...tion from the low-kinetic regime (enzymatic
hydrolysis) to the high-kinetic regime (acid hydrolysis), which strongly depends on temperature i.e. applied heating
rate. Significant compensation between kinetic parameters is a consequence of a change in the mechanism of
glucosides’ bond cleavage.
