Our project, The Greenplast Revolution, was shortlisted among the top 750 ideas out of 1,50,000 entries in the School Youth Ideathon competition, announced in the first slot of the top 750 ideas before the next 1,250 ideas were revealed, marking a significant recognition of our concept’s impact and potential. This innovation uses Nannochloropsis algae as a dual-purpose solution for creating sustainable bioplastics and purifying industrial pollution. The algae grow rapidly using sunlight and CO₂, require no farmland or freshwater, and are used to produce biodegradable, durable bioplastics reinforced with rice husk and upcycled ghost nets. At the same time, advanced algae reactors treat industrial wastewater by absorbing dyes, chemicals, and heavy metals, while vertical algae columns capture PM0.5–PM10 and remove SO₂, CO₂, and NOₓ from polluted air. With technologies like microbubble aeration, membrane filtration, and automated harvesting, the system remains efficient, scalable, and waste-free—providing cleaner water, cleaner air, eco-friendly materials, and a carbon-neutral pathway to reduce plastic waste and industrial emissions.

Description
The innovation focuses on using Nannochloropsis algae as a dual-purpose, nature-based technology for both sustainable bioplastic production and industrial pollution remediation. These microalgae grow extremely fast using only sunlight and atmospheric CO₂, and they require no agricultural land, no freshwater, and no fertilizers, making them one of the most resource-efficient biological feedstocks.
From the harvested algae, we develop fully biodegradable and durable bioplastics, further strengthened using rice husk (an agricultural waste) and upcycled ghost nets (discarded fishing nets that pollute oceans). This combination reduces dependence on petroleum-based plastics and simultaneously upcycles existing waste.
In parallel, the same algae are used in advanced environmental purification systems. Our specialized algae bioreactors treat industrial wastewater by absorbing toxic dyes, chemicals, heavy metals, and micro-pollutants, turning contaminated water into a reusable resource. Additionally, our vertical algae air-purification columns capture fine particulate matter (PM0.5–PM10) and remove harmful gases such as SO₂, CO₂, and NOₓ, thus improving air quality in highly polluted industrial zones.
To ensure efficiency and scalability, the system incorporates technologies such as microbubble aeration (for enhanced gas exchange), membrane filtration, and automated harvesting units. Together, these components create a closed-loop, waste-free, energy-efficient system that delivers multiple benefits: cleaner water, cleaner air, sustainable materials, reduced industrial emissions, and a carbon-neutral pathway for addressing plastic pollution and climate chall
