Startup aims to make toilet paper from rice straw

Startup Paddy Paper is aiming to disrupt the toilet paper industry with products made from rice straw, a byproduct of rice farming. This alternative seeks to reduce the deforestation associated with traditional wood-pulp toilet paper and address air pollution issues caused by burning agricultural waste in Asia.

Co-founder Matt Dye conceived the idea during a 2022 trip to Bangkok, where he observed severe air pollution. He learned that burning millions of tons of rice straw after harvest was a significant contributor. Globally, an estimated 450 million metric tons of rice straw are burned annually, worsening air quality and contributing to climate change. Farmers typically burn the straw due to its lack of economic value, prompting Dye to explore its potential as a raw material.

Paddy Paper's approach offers dual benefits: it provides a sustainable alternative to wood-based paper products and mitigates the environmental harm of burning rice straw. Unlike bamboo alternatives, which can compete for forest or farmland, utilizing rice straw repurposes existing agricultural residue. The company also avoids bleaching, aiming for a natural color in its products.

The manufacturing process presented a technical challenge, as rice straw fibers are stiffer than wood fibers. Paddy Paper collaborated with a Thai company to develop a pulping and tissue-making process that renders the fibers flexible enough for soft, durable tissue. According to the company, the vast global supply of rice straw could potentially replace wood fiber entirely in toilet paper production.

Paddy Paper has launched its products on a limited basis. A 12-roll box of 3-ply toilet paper is priced at $14.99 during the introductory period, and a six-roll pack of paper towels costs $11.99. The company is gathering feedback to further refine its offerings.
