This study explores thermochemical energy recovery from tomato waste, a sustainable approach to reduce agro-industrial waste. Kinetic analysis shows tomato waste is suitable for combustion, yielding valuable energy and supporting profitable circuits for processing industries.
Area of Science:
- Sustainable Development
- Thermochemical Energy Recovery
- Agro-industrial Waste Management
Background:
- Tomato processing generates significant agro-industrial waste.
- Developing sustainable and economically viable waste management solutions is crucial.
- Thermochemical processes offer a potential pathway for waste valorization.
Purpose of the Study:
- To investigate the thermochemical energy recovery potential of tomato waste.
- To analyze the thermal degradation behavior and kinetics of tomato waste.
- To support the development of efficient combustion processes for tomato residues.
Main Methods:
- Characterization of tomato waste for thermochemical processing suitability.
- Thermal and kinetic analyses to determine degradation conditions.
- Application and validation of kinetic models (Flynn-Wall-Ozawa, first-order, contracted cylinder).
Main Results:
- Tomato waste exhibits high volatiles and fixed carbon content, suitable for thermochemical processing.
- High heating values comparable to sawdust biomass were observed.
- The Flynn-Wall-Ozawa model best simulated the combustion process, with validation by other models under specific conditions.
Conclusions:
- Tomato waste is a viable feedstock for thermochemical energy recovery.
- Kinetic data obtained can guide the optimization of combustion processes and reactor design.
- This approach promotes sustainable development and creates economic opportunities in the tomato processing industry.
