Summary
Agroforestry residues require effective management for economic and environmental benefits. Valorization into products like biofuel and fertilizers is key to a circular bioeconomy, supported by sustainability assessments and policies.
Area of Science:
- Agricultural Science
- Environmental Science
- Biotechnology
Background:
- Agroforestry generates significant residues, posing waste management challenges.
- Conventional methods like landfilling have environmental disadvantages.
- Effective management is crucial for economic and environmental gains.
Purpose of the Study:
- To review agroforestry waste management strategies.
- To assess sustainability based on social, economic, and environmental parameters.
- To promote a circular bioeconomy through waste valorization.
Main Methods:
- Review of waste collection, transportation, and recycling channels.
- Analysis of pretreatment technologies (fermentation, hydrolysis, gasification).
- Evaluation of sustainability assessment models (technoeconomic, life cycle, multi-criteria).
Main Results:
- Biowaste to bioenergy technology market is substantial and growing.
- Pretreatment technologies enhance waste valorization and overcome mobilization barriers.
- Sustainability assessment requires integrated social, economic, and environmental factors.
Conclusions:
- Implementing effective waste management strategies is vital for sustainable agroforestry.
- Valorization into biofuels, fertilizers, and biochar supports a circular bioeconomy.
- Policy interventions are necessary to address sector loopholes and promote sustainability.
