Biological Treatment Technologies Market Report 2025

The biological treatment technologies market size has grown strongly in recent years. It will grow from $2.74 billion in 2024 to $2.96 billion in 2025 at a compound annual growth rate (CAGR) of 7.9%. The growth observed during the historic period can be attributed to the increasing emphasis on the circular economy and resource recovery, the rising need for decentralized and small-scale treatment systems, growing investments in wastewater infrastructure projects, the expanding adoption of biological processes in developing economies, and a heightened focus on minimizing chemical use in wastewater treatment.

The biological treatment technologies market size is expected to see strong growth in the next few years. It will grow to $3.96 billion in 2029 at a compound annual growth rate (CAGR) of 7.6%. The growth projected for the forecast period is driven by the escalating demand for sustainable wastewater treatment solutions, heightened environmental awareness and public health concerns, stricter enforcement of wastewater discharge regulations, the increasing adoption of eco-friendly waste management practices, and the surge in industrialization and urban wastewater generation. Key trends expected in the forecast period include technological advancements in microbial treatment processes, progress in hybrid biological treatment technologies, a technology-led shift towards decentralized wastewater treatment, the integration of real-time data analytics for process optimization, and innovations in anaerobic digestion systems.

The increasing generation of industrial waste is anticipated to drive the growth of the biological treatment technologies market in the future. Industrial waste generation involves the production of unwanted materials and by-products during industrial and manufacturing operations. This rise in industrial waste is mainly due to rapid industrialization, which leads to increased production activities and consequently more waste by-products. Biological treatment technologies assist in managing industrial waste by utilizing microorganisms to degrade organic pollutants, thus reducing the waste’s volume, toxicity, and environmental impact. For example, in May 2025, the World Bank Group, a US-based international financial institution, reported that over 2 billion metric tons of municipal waste are produced annually, a figure expected to increase by 73% to reach 3.88 billion metric tons by 2050. Hence, the growing industrial waste generation is fueling the expansion of the biological treatment technologies market.

Leading players in the biological treatment technologies market are enhancing their presence by strategically expanding wastewater treatment plants to meet stricter environmental regulations. This expansion increases processing capacity, improves pollutant removal efficiency, and promotes sustainability, allowing companies to treat both internal and third-party industrial wastewater more effectively. For instance, LANXESS AG, a Germany-based chemical firm, inaugurated a new biological wastewater treatment plant to advance sustainable water management at its facility. This plant uses microorganisms to effectively eliminate organic pollutants and pathogens, yielding cleaner water that safeguards public health and the environment. Benefits include environmental sustainability, a compact system design, compliance with regulations, and better protection of public health.

In September 2024, Axius Water European Holdings Limited, a US-based wastewater treatment firm, acquired MITA Water Technologies for an undisclosed sum. Through this acquisition, Axius Water aims to curb nutrient pollution, broaden its presence in Europe, and offer a wider range of water and wastewater solutions. MITA Water Technologies is an Italy-based company specializing in biological wastewater treatment solutions.

Note that the outlook for this market is being affected by rapid changes in trade relations and tariffs globally. The report will be updated prior to delivery to reflect the latest status, including revised forecasts and quantified impact analysis. The report’s recommendations and conclusions sections will be updated to give strategies for entities dealing with the fast-moving international environment.

The rapid escalation of U.S. tariffs and the resulting trade tensions in spring 2025 are significantly impacting the utilities sector, particularly in power generation, grid infrastructure, and renewable energy projects. Higher duties on imported equipment such as turbines, transformers, solar panels, and battery storage systems have increased capital and operational costs for utility providers, forcing them to reconsider project timelines or pass on expenses to consumers through higher energy rates. The water and waste management segments are also affected, with tariffs driving up the cost of essential machinery, piping, and treatment technologies. Additionally, retaliatory tariffs have disrupted global supply chains for critical raw materials like rare earth metals used in clean energy technologies, further complicating the transition to sustainable energy sources. The sector must now prioritize domestic sourcing, digitalization, and efficiency-driven innovations to manage escalating costs while ensuring energy security and regulatory compliance.

Biological treatment technologies utilize microorganisms to degrade organic pollutants found in wastewater or contaminated environments. These methods depend on natural metabolic activities to transform harmful substances into harmless byproducts such as water, carbon dioxide, and biomass. Their main objective is to minimize environmental pollution and promote sustainable waste management.

The key types of biological treatment technologies include composting, vermicomposting, black soldier fly treatment, anaerobic treatment, and fermentation. Composting involves the controlled aerobic decomposition of organic waste by microorganisms to generate a stable product. These technologies encompass aerobic, anaerobic, and hybrid treatment methods. They are available in various system sizes, including small-scale, mid-scale, and large-scale. The primary end users consist of municipalities, industries, agriculture, and the commercial sector.
