Top 10 Companies in the Biosolids Market (2026): Market Leaders Driving Sustainable Waste Management

MARKET INSIGHTS

Global biosolids market size was valued at USD 6.98 billion in 2024. The market is projected to grow from USD 7.32 billion in 2025 to USD 9.60 billion by 2032, exhibiting a CAGR of 4.8% during the forecast period.

Biosolids are nutrient-rich organic materials derived from wastewater sludge, primarily produced during sewage treatment processes. They consist of water, organic matter, and beneficial nutrients like nitrogen and phosphorus, making them valuable for agricultural applications. These by-products originate from residential, commercial, and industrial wastewater sources.

The market growth is driven by increasing wastewater treatment activities globally, stricter environmental regulations promoting sustainable waste management, and growing adoption in agricultural applications. Furthermore, technological advancements in biosolid treatment processes, such as thermal hydrolysis and anaerobic digestion, enhance their safety and usability. Key players like Suez, Veolia, and American Water Works dominate the market, collectively holding approximately 33% share. However, public concerns about heavy metal contamination and odor issues pose challenges to widespread adoption.
