Asia Pacific currently dominates the market, holding a market share of over 35.0% in 2024. The biosolids market share is rising due to the increased wastewater treatment activities, organic fertilizer demand, environmental regulations, advances in processing technologies, agricultural applications, and reduced dependence on chemical fertilizers.

The biosolids market growth is increasing as sustainable waste management practices become a global priority. Biosolids, the nutrient-rich organic byproduct of treated wastewater, are widely used in agriculture, land reclamation, and energy production. It will be of more value to today's farmers with the capability of improving soil health and reducing their use of chemical fertilizers. Governments and environmental agencies are advocating biosolids as a more sustainable option for soil amendment and waste management. Improvements in their quality have been achieved through the use of advanced treatment technologies like composting and anaerobic digestion, thus expanding their potential applications.

The largest end-use sector for biosolids remains agriculture, due to the organic matter and necessary nutrients in them. There is also a growing interest in renewable energy that has increased its application in biogas production. While regulatory challenges and public perception issues exist, advancements in processing technology and stringent quality standards are addressing concerns about contaminants. With increasing awareness about circular economy principles, biosolids are becoming an integral part of sustainable environmental solutions. As industries seek eco-friendly alternatives, the market is expected to expand, offering opportunities for innovation in waste management and resource recovery.

The United States emerged as a key regional market for biosolids, driven by the ever-increasing need for sustainable solutions to waste management and agriculture. Biosolids are nutrient-rich materials that have been produced by processing sewage sludge and are, therefore, greatly applied in farmlands for fertilizer and soil conditioner purposes. Strict environmental policies that would seek to recycle the biosolids rather than throw them into landfills tend to benefit the market as they are developed by the EPA. This goes in line with the increased emphasis on circular economy practices and organic farming solutions.

Despite the various uses of biosolids that help improve soil health, significant challenges remain, from anxiety over heavy metal contamination to generally negative public perception. These problems are addressed through many U.S. states adopting advanced treatment technologies such as composting, thermal drying, and anaerobic digestion, which increase the quality of biosolids. In addition, the use of biosolids has expanded beyond agriculture to include land reclamation and energy production, making it a versatile solution for waste management and environmental sustainability.

Biosolids Market Trends:

Shift toward sustainable agriculture

The decline in arable land worldwide is one of the significant factors in shaping the biosolids market trends in agricultureThe UNCCD projects that the world lost at least 100 Million hectares of productive and healthy land every year from 2015 to 2019. Soil degradation, urbanization, and climate change continue to reduce the fertile land available for cultivation, hence increasing the need for sustainable soil amendments. Biosolids are rich in organic matter and essential nutrients, thus enhancing soil health, structure, and water retention capacity. Governments and agricultural organizations worldwide are actively promoting biosolid-based fertilizers to counteract soil erosion and degradation.

Policies supporting sustainable farming practices are further accelerating the adoption of biosolids in both commercial and small-scale farming. Biosolids applications are growing rapidly in countries with large agricultural sectors, such as India, China, and Brazil, where farmers are looking for cost-effective and eco-friendly fertilization methods.

Furthermore, with land resources dwindling, the need to maximize agricultural productivity has increased. Biosolids increase soil microbial activity, thereby improving nutrient availability and crop yields. Biosolids are anticipated to grow with this increased awareness regarding the issues of food security and soil conservation as biosolids increase their potential use in farms and make way for being key players in future, modern green agriculture.

Growing consumer demand for organic farming

Increasing customer awareness about the devastating impact of chemical-based pesticides and fertilizers has raised increasing demand for an organic method of farming. Subsequently, it triggers a biosolid market. Consumers worldwide are becoming more health-conscious, and demand for organic food products is on the rise. Industry reports state that about 34% of American consumers have included organic foods in their diets. This chemical-free and sustainably grown food trend is forcing farmers and agribusinesses to take up biosolids as a natural and eco-friendly soil amendment.

Such valuable constituents include nitrogen, phosphorus, and potassium as applied nutrients in a very natural yet efficient way from organic farming devoid of synthetic chemical supports. Several regulations over organic farming currently recognize biosolids as useful soil conditioners, thus widely increasing usage. Europe and North America appear most affected as strict agricultural policy ensures sustainable substitutes for fertilizer and synthetic fertilizers.

In addition, major biosolid producers are producing organic-certified biosolids to meet this emerging market. These products meet organic farming requirements, however, provide enhanced soil fertility and crop health benefits. As consumers increasingly focus on sustainability and natural food production, biosolids use in organic farming is expected to increase significantly shortly.

Expanding wastewater treatment facilities

Increasing demand for clean water and efficient waste management is another factor responsible for boosting biosolids demand. Industrialization and population growth have led to increased industrial and municipal wastewater volumes, requiring enhanced treatment processes. Biosolids are a byproduct of wastewater treatment that is taking greater importance due to their useful applications in agriculture, land reclamation, and landscaping. Many governments are investing in modern wastewater treatment facilities, ensuring a steady supply of high-quality biosolids for various end uses. In addition, the increased popularity of urban greening initiatives, such as parks, gardens, and golf courses, is supporting biosolid adoption.

Biosolids are a cost-effective and sustainable soil amendment for large-scale landscaping projects, improving soil structure and fertility. The trend of home gardening is also contributing to market growth, with more consumers seeking organic soil enhancers for their personal green spaces. As per the research, the global gardening equipment market reached USD 40.6 Billion in 2024, indicating a strong demand for gardening and landscaping solutions.

Biosolids Industry Segmentation:

The research provides an analysis of the key trends in each segment of the global biosolids market, along with forecasts at the global, regional, and country levels from 2025-2033. The market has been categorized based on product type, form, and application.

Analysis by Product Type:

• Class A Biosolids
• Class A (EQ) Biosolids
• Class B Biosolids

The Class A biosolids dominate the market with a share of 53.2%. They are processed for compliance with stringent environmental criteria, hence posing no risks of pathogenic contamination and being safe for agricultural and non-agricultural use. Such a level of treatment makes Class A biosolids highly attractive, especially in agriculture where organic material is used as fertilizer. The widespread acceptance of Class A biosolids is on account of enhanced regulatory pressure toward safer waste treatment, environmental sustainability, and eco-friendly practices. Thus, the rise in organic practices among farmers can be supplemented best by Class A biosolids, which contain high nutrients without any harmful contaminants.

The superior quality and safety of Class A biosolids, compared to Class B (which still may contain trace pathogens), positions them as the preferred choice in both developed and developing regions. Additionally, the global trend toward reducing synthetic chemical fertilizers further boosts the adoption of Class A biosolids, as they are perceived as a sustainable alternative. This has been enhancing growth in the agricultural industry where Class A biosolids are utilized for crop production and soil enhancement, thus establishing their monopoly in the industry.
