Biological Treatment Technologies Market Report 2026

The biological treatment technologies market size has grown strongly in recent years. It will grow from $2.96 billion in 2025 to $3.19 billion in 2026 at a compound annual growth rate (CAGR) of 7.7%. The growth in the historic period can be attributed to stricter wastewater discharge regulations, expansion of municipal wastewater treatment infrastructure, increasing organic waste generation, adoption of composting technologies, growth of industrial effluent treatment facilities.

The biological treatment technologies market size is expected to see strong growth in the next few years. It will grow to $4.25 billion in 2030 at a compound annual growth rate (CAGR) of 7.5%. The growth in the forecast period can be attributed to increasing investments in sustainable waste treatment, rising adoption of decentralized treatment systems, expansion of bioenergy production from waste, growing focus on nutrient recovery solutions, increasing demand for low-emission treatment technologies. Major trends in the forecast period include increasing adoption of anaerobic digestion systems, rising deployment of black soldier fly treatment solutions, growing integration of hybrid biological treatment technologies, expansion of large-scale waste processing facilities, enhanced focus on resource recovery and circular waste management.

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.

Major companies operating in the biological treatment technologies market are emphasizing the development of innovative solutions, including advanced microbial formulations and bio-based treatment systems, to increase efficiency, strengthen environmental sustainability, and lower operational costs. Microbial formulations are carefully developed blends of beneficial microorganisms intended to enhance biological processes such as waste breakdown, water treatment, and soil or crop health. For example, in October 2025, EnviroZyme LLC, a US-based microbial biotechnology company, introduced Aqualytics, a microbiology-driven product portfolio designed for aquaculture to improve water quality and pond performance. The Aqualytics range leverages beneficial microbes to reduce toxic compounds, control organic waste, and stabilize pond ecosystems in fish and shrimp farming operations. This launch highlights the growing adoption of sustainable, biology-based solutions to boost productivity and minimize environmental impact within the aquaculture sector.

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.
