was tested in compost environments. Newsprint without ink degraded fully in 18 days, while inked newsprint degraded slower due to lignin and metal-based inks. Glossy and recycled papers degraded faster, within 14 and 16 days, respectively. Composting paper with manure transforms carbon into stable forms, enriching soil health. Nitrogen is converted into plantavailable forms, aiding long-term soil fertility. Compost stability increases as more resistant organic materials are synthesized. Composting reduces landfill waste, methane emissions, and air pollution, while promoting recycling. It is economically viable and crucial for waste management sustainability. Combining paper waste with activated charcoal and vermicomposting produces nutrient-rich fertilizers, especially in India, and can be used for sustainable agriculture. Research shows that most paper types, including white and recycled paper, do not meet biodegradation standards within 45 days, requiring longer composting times to fully decompose. Anaerobic digestion is the most efficient waste treatment method for biodegradable materials, combining energy recovery with soil conditioning. Composting can sometimes emit more greenhouse gases than landfilling, though it avoids methane production. Lignin content reduces paper biodegradability. Optimal degradation occurs at 4050°C, aided by thermophilic fungi. The manufacturing process of paper affects its degradation rates. Organic matter in compost stabilizes as easily degradable compounds break down. Composting mixtures of green waste, bio waste, and paper require a balance for optimal organic matter stabilization. Composting reduces methane emissions compared to landfilling, which is a major source of global greenhouse gases. While both systems have environmental impacts, composting is generally more proactive in reducing emissions. Vermicomposting produces finer compost particles with lower nutrient content but is more efficient in managing paper waste. Windrow composting yields higher nutrient levels but has more heavy metals, affecting its application in agriculture. Different waste types emit varying levels of CO2 and ammonia during composting. Food waste generates the highest emissions, while mixed paper waste produces the least. This helps predict environmental impacts of composting different materials. Composting organic materials like manure, orange peels, and wheat straw can improve soil health and suppress plant diseases. It is an effective alternative

1. INTRODUCTION In recent years, researchers have explored the environmental benefits of composting, particularly with paper products and organic waste. Composting turns organic waste into valuable soil amendments, helping to reduce landfill use, lower greenhouse gas emissions, and create nutrient-rich fertilizers. However, different types of paper and organic waste degrade at varying rates, depending on factors like the presence of ink, lignin content, and the composting process used. Studies have shown that newsprint paper, especially with ink, decomposes slower than glossy or recycled papers due to its chemical composition. Ink and lignin resist biodegradation, especially in nutrient-rich environments. Other research focuses on composting's ability to stabilize organic matter, releasing nutrients gradually and supporting long-term soil health. Moreover, integrating waste paper into composting systems, particularly when combined with organic materials like animal manure, has been proven to improve the soil’s nutrient content and reduce environmental pollutants. Composting is widely recognized as a sustainable alternative to traditional waste disposal methods like landfilling, which contributes significantly to methane emissions. While composting can emit some greenhouse gases, its overall environmental impact is less harmful than landfills, especially when combined with effective waste management strategies. Composting paper waste not only reduces the
