The Sustainable Revolution: Stone Paper as an Eco-Friendly Alternative in a Circular Economy, with a Special Focus on India

Abstract

The global demand for paper and packaging escalates environmental degradation through deforestation, water pollution, and plastic waste. This paper provides a technical and sustainability life-cycle comparison of traditional wood-pulp paper, polymer synthetic paper, and an emerging alternative: stone paper. Composed of 80% calcium carbonate waste and 20% high-density polyethylene (HDPE) binder, stone paper utilizes a dry manufacturing process that eliminates tree harvesting, consumes zero freshwater, avoids toxic chemical bleaching, and reduces carbon emissions by approximately 67% compared to traditional paper. The study places a special emphasis on India, exploring how stone paper can upcycle hazardous regional marble slurry waste and align with strict domestic plastic waste policies and net-zero goals. While stone paper accelerates circular economy principles through photodegradation and closed-loop technical recycling, challenges remain regarding its higher cost, consumer awareness, and potential contamination of standard plastic recycling streams.

The paper concludes that with targeted policy incentives and infrastructure development, stone paper offers a highly viable paradigm shift toward industrial de-carbonization.
