The rising demand for wastewater treatment is anticipated to propel the growth of the non-dispersive infrared (NDIR) market in the coming years. Wastewater treatment involves the removal of contaminants from wastewater or sewage, transforming it into effluent that can be safely reintroduced into the water supply with minimal environmental impact. Non-dispersive infrared sensors are utilized to monitor nitrate, nitrite, and ammonia levels in municipal wastewater treatment facilities and onsite wastewater treatment systems in real time. For example, in August 2024, UN-Water, a Switzerland-based interagency mechanism of the United Nations, reported that globally, 42% of household wastewater was not treated safely before discharge in 2022, leading to an estimated 113 billion cubic meters being released into the environment. This underscores the urgent need for enhanced water quality and the aim to halve untreated wastewater while improving recycling and safe reuse by 2030. Consequently, the increasing need for wastewater treatment is driving the growth of the non-dispersive infrared (NDIR) market.

The forthcoming growth of the non-dispersive infrared (NDIR) market is expected to be propelled by the burgeoning automotive industry. Encompassing the design, development, production, and maintenance of motor vehicles, the automotive sector relies on non-dispersive infrared (NDIR) sensors for various crucial applications due to their high-precision detection and measurement capabilities for specific gases. According to the European Automobile Manufacturers Association (ACEA), the global production of automotive vehicles reached 85.4 million units in 2022, reflecting a 5.7% increase from 2021. Hence, the expanding automotive industry serves as a driving force for the non-dispersive infrared (NDIR) market.

A prominent trend gaining momentum in the non-dispersive infrared (NDIR) market is the surge in technological advancements. Key players in the non-dispersive infrared (NDIR) sector are actively engaged in developing technological solutions, as evidenced by Yokogawa Electric Corporation's recent introduction of three new infrared gas analyzers. These analyzers employ non-dispersive infrared (NDIR) technology to accurately detect and measure concentrations of greenhouse gases such as carbon dioxide, nitrogen dioxide, sulfur dioxide, and methane. This focus on technological innovation contributes to the evolving landscape of the non-dispersive infrared (NDIR) market.

Key players in the non-dispersive infrared (NDIR) market are concentrating on advanced solutions, including high-sensitivity detection, to support industrial companies in meeting new EU regulations on methane emissions. This focus contributes to environmental sustainability and the reduction of greenhouse gases. High-sensitivity detection arises from NDIR sensors' ability to accurately measure low concentrations of target gases by detecting specific infrared absorption wavelengths without using dispersive elements, facilitating precise gas concentration analysis. For instance, in May 2024, ABB Ltd., a Switzerland-based engineering firm, unveiled OA-ICOS technology designed to assist industrial companies in adhering to the forthcoming EU Methane Regulation. This technology offers sensitivity more than 1,000 times greater than traditional methods and detects leaks 10 times faster than conventional equipment, enabling the accurate location, attribution, and quantification of gas leak sources. This innovation is crucial as it enables industrial companies to identify and prioritize essential repairs, ensuring compliance with strict EU regulations on methane emissions and supporting global efforts to mitigate greenhouse gases.

In May 2023, smartGAS, a Germany-based manufacturer of high-precision NDIR gas sensors, merged with SIGAS. This merger aims to optimize both companies' upstream and downstream industrial chains. SIGAS, based in China, specializes in industrial gas analysis equipment and provides comprehensive gas monitoring systems.
