University of Hyderabad Converts Geranium Waste into Low-Cost Biochar

IN NEWS: University of Hyderabad Converts Geranium Waste into Low-Cost Biochar

Why Geranium Biochar is in News?

The University of Hyderabad (UoH) has successfully developed a method to convert Geranium waste generated during oil extraction into low-cost biochar, which has been proven to enhance soil fertility and plant growth. The process is energy-efficient and economical, making it a promising solution for sustainable agriculture.

What is Geranium Biochar?

Geranium biochar is a carbon-rich product produced from Geranium leaf waste, including pre- and post-oil extraction residues. It functions as a soil amendment and carbon-storage material, contributing to improved plant growth and soil health.

Objectives

1. To upcycle Geranium plant residue into a value-added agricultural product.
2. To promote sustainable waste utilization and reduce environmental load.
3. To design a cost-effective and energy-efficient biochar production method.
4. To explore soil enhancement solutions for improving crop yield.
5. To support circular bioeconomy practices in agriculture.

Role and Functions of Geranium Biochar

1. Improves Soil Quality – enhances nutrient availability and soil structure.
2. Carbon Sequestration – stores carbon in stable form, reducing emissions.
3. Plant Growth Enhancer – demonstrated effective growth support in Rosemary crops.
4. Waste Utilization – transforms discarded Geranium biomass into productive resource.
5. Cost Reduction for Farmers – low production cost increases accessibility.

Research Details

1. Research conducted by University of Hyderabad involving Life Sciences and Engineering Sciences & Technology departments.
2. Project led by scientists Appa Rao Podile and V.V.S.S. Srikanth.
3. Findings published in the Biomass and Bioenergy journal.
4. Biochar produced contains ~65% carbon along with essential minerals.
5. Trial application on soil demonstrated positive growth response in Rosemary plants.

Significance

1. Helps reduce agricultural waste disposal issues.
2. Supports soil rejuvenation in degraded farmlands.
3. Contributes to climate mitigation through carbon storage.
4. Encourages scaling of biochar-based soil management in India.
5. Useful across multiple regions cultivating aromatic crops for oils.

Way Forward

1. Large-scale pilot projects needed to integrate Geranium biochar in farming systems.
2. Promote farmer awareness and field demonstrations for adoption.
3. Encourage research on multi-crop applicability and soil type-specific performance.
4. Government support through subsidy and policy incentives for biochar technologies.
5. Explore commercial production linking agro-industries, farmers, and research institutions.
