Silica removal
NaOH pretreatment at 90–95°C dissolves 10–15% silica, freeing cellulose for hydrogen bonding.

We convert Punjab's, Haryana, Uttar Pradesh & other's rice-straw/parali waste into premium, waterproof, biodegradable paper packaging — turning air-choking stubble burning into a scalable, profitable ecosystem.
Carbon Negative closes two loops at once — the plastic packaging crisis and the rural burning of crop residue. We source rice-straw/parali from Punjab, Uttar Pradesh, Haryana & other's state farmers and refine it into compostable paper that rivals plastic on strength and moisture-resistance.

Every autumn, millions of tons of parali are burned across Punjab, Haryana, Uttar Pradesh, and neighboring agricultural states—sending a vast blanket of smoke across northern India like (Delhi facing air pollution) and creating a recurring public health and environmental crisis.
Packaging drives roughly forty percent of the world's plastic waste. Bans are tightening across the EU and North America — but scalable alternatives have been scarce.
Every year, over 150 million tons of rice straw are burned or discarded across Asia—not because it lacks value, but because its high silica content has made it economically difficult to convert into quality paper. Our lab-validated process changes that.
Our innovation transforms a pollution problem into an industrial resource. By unlocking rice straw as a high-performance fiber, we create sustainable packaging that benefits farmers, brands, and the planet—without compromising performance.
Carbon Negative rewires the incentive: farmers earn, air clears, plastic retreats. This is what the solution looks like.
Discover the SolutionA six-step, farm-to-shelf process that transforms waste into premium packaging — with every input either recycled or fully compostable.
Partner with farmers to gather post-harvest straw — an income stream, not a burn pile.
Gentle alkali at 90–95°C removes silica, freeing cellulose fibers for bonding.
Closed-loop pulping at ~85% efficiency with minimal NaOH & full water recycling.

Identified rice straw's untapped pulpability and the plastic packaging gap.
reduced silica by over 15% and produced the first 70 GSM rice straw (parali) paper sheets. The next goal is to achieve 150 GSM paper. Several experiments have been completed, and development is still in progress.
Successful silica reduction >90%. First 300 GSM rice straw (parali) paper sheet produced — achieved a heavy-duty paper sample in the lab.
Successful silica reduction >90%. First 300 GSM rice straw (parali) paper sheet produced. Rosin and wax sizing provided moisture resistance without plastic coating, achieving a heavy-duty paper sample in the lab.
Farmer partnerships, machine sourcing, and first commercial samples.
Bags & mailers shipped to pilot brands. Expansion capital raise.
Optimize the process, improve efficiency, and prepare for commercial production.
Due to its open microporous structure and low lignin content, rice-straw / parali is easily pulpable and bleachable.

Every ton of straw/parali diverted from burning becomes farmer income, reduced PM2.5, and premium packaging that displaces virgin plastic.
