Environment & Energy Industry
Sustainable solutions for wastewater treatment, effluent processing, and waste-to-energy conversion.
Sustainable solutions for wastewater treatment, effluent processing, and waste-to-energy conversion.
The environment and energy sector has become critical to global sustainability, addressing industrial wastewater treatment, municipal sewage processing, and renewable energy generation from organic waste. With over 45,000 ETPs operating worldwide and strict environmental regulations expanding, the industry is experiencing unprecedented growth.
Global wastewater generation exceeds 300 billion cubic meters annually, while biogas production transforms waste into clean energy. The convergence of water treatment and energy recovery creates circular economy opportunities, with sludge from ETPs becoming feedstock for biogas plants and treated water returning to industrial processes.
Understanding the scale and growth of the environmental solutions and renewable energy sector.
The global industrial wastewater treatment market was valued at USD 19.06 billion in 2024, projected to reach USD 28.95 billion by 2032. The ETP market specifically is at USD 7.92 billion, expected to grow to USD 12.62 billion by 2033. India leads new installations with 2,200+ units in three years.
The biogas market reached USD 65.9 billion in 2024, expanding to USD 126.2 billion by 2034 at 6.7% CAGR. Germany operates 10,000+ biogas plants, while Asia-Pacific drives growth with 45.9% market share. Waste-to-energy adds another USD 48 billion to the renewable energy sector.
Anaerobic digestion dominates biogas production with 93.3% market share, processing municipal waste (53.6%), agricultural residues, and sewage sludge. Europe leads with 53.6% of biogas production, while textile, chemical, and food industries account for 54% of industrial wastewater.
Major factors shaping the future of environment and energy sectors
The environment and energy industry serves diverse sectors with specialized treatment and energy solutions.
Treatment of effluent from textile, chemical, food, and manufacturing industries. Includes primary, secondary, and tertiary treatment stages with strict discharge compliance.
Sewage treatment plants processing domestic wastewater and producing biosolids. Municipal waste contributes 53.6% of biogas feedstock globally.
Anaerobic digestion of organic waste producing biogas for energy and biomethane for grid injection. Agricultural waste and sludge are primary feedstocks.
Converting non-recyclable waste to electricity and heat through incineration, gasification, and pyrolysis. Growing alternative to landfilling.
Converting wastewater and organic waste into clean water and renewable energy.
Modern environmental systems integrate water treatment with energy recovery. Industrial effluent undergoes primary (physical), secondary (biological), and tertiary (advanced) treatment before discharge or reuse. Organic sludge and waste become feedstock for anaerobic digestion, producing biogas (60% methane, 40% CO2) for heat, power, or biomethane upgrading.
Multi-stage treatment including screening, sedimentation, biological treatment (activated sludge, MBBR), and advanced processes (membrane filtration, ozonation). Produces treated water meeting discharge or reuse standards.
Processing waste sludge through thickening, conditioning, and dewatering using belt presses, centrifuges, or filter presses. Reduces volume by 80-90% for disposal or energy recovery feedstock.
Anaerobic digestion of organic matter in oxygen-free environment producing biogas. Digestate becomes fertilizer. Biogas can be used directly, converted to electricity, or upgraded to biomethane.

The environment and energy sector faces challenges in efficiency, compliance, and technology adoption.
Environmental treatment facilities must meet increasingly strict discharge standards while managing energy costs and sludge disposal. The industry is transitioning toward resource recovery - treating wastewater as a source of water, energy, and nutrients rather than waste to be disposed.
EPA, EU Water Framework, and local regulations impose strict effluent limits. Industries face penalties for non-compliance and must invest in advanced treatment technologies.
Aeration and pumping consume significant energy. Biogas recovery and efficient equipment help offset costs. Smart controls optimize energy use.
Increasing sludge quantities require effective handling, treatment, and disposal or beneficial use. Biogas production transforms sludge into energy asset.
Water stress regions require treated water reuse. Zero liquid discharge (ZLD) systems recover nearly all water for recycling.
