Know How Agri Researchers are Converting Plastic and Biomass into Manure and Pesticide for Farmers

In a successful initiative, agricultural researchers have excelled a method to convert plastic and biomass into valuable resources such as manure and pesticides. Spearheaded by the University of Agricultural Sciences, GKVK, this innovative approach holds promise for addressing environmental challenges while benefiting farmers.

1. Pyrolysis Process:

The key to this transformation lies in a process called pyrolysis, a tertiary recycling technique. Pyrolysis involves heating higher molecular weight organic polymers like plastic and biomass to high temperatures in the absence of oxygen. This results in the conversion of the materials into liquid oil, char, and gases. The process doesn't involve burning the waste, making it environmentally friendly.

2. Surprising Results:

The researchers installed a pyrolysis unit which yielded unexpected results. Plastic waste subjected to pyrolysis produced char, a vital material used in asphalt and brick manufacturing. Additionally, the process generated syngas, a clean-burning fuel that powers the pyrolysis unit itself, and bio-oils with various energy applications.

3. Environmental Benefits:

Processing biomass through pyrolysis also produces biochar, often referred to as "black gold" by agricultural experts. Biochar improves soil quality, enhances water retention, boosts nutrient availability, and aids carbon sequestration. Importantly, the carbon in biochar does not contribute to greenhouse gas emissions, making it an environmentally sustainable solution.

4. Economic Opportunities:

Dr. SV Suresha, Vice-Chancellor of UAS, highlighted the economic potential of the pyrolysis unit. Apart from producing valuable resources, it also generates hydrogen gas, enabling farmers to earn additional income through government schemes like BioUrja. This aligns to promote low operating costs and utilize locally available biomass.

5. Future Prospects:

UAS aims to collaborate with the government and industries to further commercial research on biochar usage. This initiative intends to promote the adoption of biochar among local farmers, offering benefits such as improved soil health, reduced greenhouse gas emissions, and additional income streams.

Conclusion:

The conversion of plastic and biomass into valuable resources through pyrolysis marks a significant step forward in sustainable agriculture. By harnessing innovative techniques like pyrolysis, researchers are not only addressing environmental challenges but also creating economic opportunities for farmers. With ongoing efforts and collaborations, the adoption of biochar holds the promise of a greener and more prosperous agricultural future.
