The Zacks Pollution Control industry is benefiting from strong demand for air pollution control products as greenhouse gas emissions rise and associated health risks increase. Strict regulations and emission standards enacted by countries globally should continue to drive demand for industry participants.
However, the growing adoption of renewable sources of energy with a rising preference for alternative fuels has marred the outlook of the industry. Donaldson Company, Inc., CECO Environmental Corp., Fuel Tech, Inc. and LiqTech International, Inc. are likely to capitalize on these opportunities.
About the Industry
The Zacks Pollution Control industry comprises companies engaged in providing innovative filtration systems, replacement parts, solutions for managing medical wastes, energy recovery devices and other products. These products are primarily used in the commercial, automotive repair, industrial, home healthcare, retail, construction, pharmaceutical and hospitality end markets.
A few industry participants offer solutions for industrial waste and commercial chemical products and technologies to tackle air pollution. One of the companies also delivers services related to infrastructure, water, resource management, energy, etc., to government and commercial clients. These companies are increasing investment in innovative technologies, improving customer and employee experience, and advancing supply-chain modernization programs.
Major Trends Shaping the Future of the Pollution Control Industry
Strong Demand for Air Pollution Control: Rapid urbanization and the consequent rise in greenhouse gas emissions from the industrial sector have been driving demand for air quality control systems. Increasing public awareness of the health-related risks associated with air pollution is fueling market growth. Also, the expansion of infrastructure-related projects in developing countries is boosting the demand for pollution abatement equipment and technologies.
Stringent Government Regulations: Strict emission standards and related laws implemented by countries worldwide to tackle ozone depletion and protect ecosystems should continue to boost demand for pollution-control equipment. Europe has some of the strictest pollution control laws in place. Solid demand for medical, pharmaceutical and hazardous waste management services is boosting the prospects of some industry participants. Also, increased usage of Artificial Intelligence (AI) and the Internet of Things (IoT) in industrial processes has been enabling several industrial companies to monitor and identify the source of air pollution in real time, thus driving demand for pollution abatement technologies.
Emergence of Alternative Sources of Energy: The growing preference for renewable energy sources for power generation to reduce dependency on coal in the United States and other developed countries across the world is restraining the demand for industrial emission-abatement products and technologies. Several factors, including supportive government policies for renewable energy, higher renewable investments, lower costs of generating renewable electricity and the rapid adoption of electric vehicles (EVs), have made the industry's prospects gloomy for players.
