Emissions testing for Solid fuels and Biomass
In the majority of Indian industrial and agricultural processes, solid fuels such as wood, cow dung, and agricultural residue are still burned for energy. While popularly believed to be cheap and easily accessible, burning these fuels contributes significantly to solid fuel emissions, which have far-reaching implications, not only for environmental sustainability, but for regulatory compliance and sustainable operations, too. The problem extends far beyond what is perceived as smoke; it’s a question of measuring emissions accurately and reducing their impact on air quality, human health, and the environment.
With more than 160 million solid fuel-using households and numerous small industries relying on similar burning systems, India has a complicated emissions challenge. At the heart of solving the issue is one simple requirement: repeatable biomass emissions testing in actual conditions.
Growing Biomass Demand: A Consequence of the National Biomass Mission 2021
The need for biomass as an alternate energy source has risen dramatically in recent years, especially following the launch of the National Biomass Mission 2021, or the National Mission on Use of Biomass in Thermal Power Plants. The mission, driven by the Ministry of Power, aims to meet the twin goals of utilizing surplus agricultural residue and curbing rising air pollution levels. It promotes the use of biomass briquettes and pellets as co-fuel in thermal power plants, thus converting waste into energy and reducing coal dependence.
The mission, in this manner, has created a ripple effect throughout the industries and Indian power producers. Biomass is no longer a small or rural fuel it’s being mainstreamed into large-scale power systems. The policy push has led to investment in biomass pellet manufacturing, biomass supply chains, and upgradation of combustion technology in industry segments.
While the government has imposed challenging co-firing targets (up to 5–10% blending of biomass into coal-fired power plants), industries now seriously consider biomass—not only on grounds of sustainability, but also as a regulatory and operational imperative. This renders actual-use emissions testing more important, as new combustion conditions and fuel blends are to be tested under actual use conditions to guarantee compliance and performance optimization.

Emission Facts from Combustion of Biomass
Haryana, India, on-site measurements determined solid fuel combustion emissions used or uncontrolled were considerably greater than laboratory testing. This is especially the case with fine particulate matter (PM2.5), an emissions component strongly associated with cardiovascular and respiratory health impacts and diminished atmospheric visibility.
Key results were PM2.5 emission factors such as:
- 10.5 g/kg for fuelwood
- 11.1 g/kg for crop residue
- 22.6 g/kg for cattle manure
These high scores emphasize the difference between use and testing under standardized conditions—most applicable to companies wishing to buy air quality standards or implement emissions reductions.
Besides, high OC and EC emission rates were also recorded, both of which are extremely significant indicators of combustion quality and significant climate forcing agents. Above all, the OC/EC ratios signify the dominance of incomplete combustion in the majority of field conditions, and that results in environmental harm.

Climate Impact and Compliance: Rethinking Biomass in Industrial Use
Biomass is generally promoted as a carbon-neutral, renewable fuel. Its performance in environmental terms in industrial applications is highly sensitive to combustion efficiency, fuel selection, and emissions control. While biomass is a theoretically carbon-neutral fuel on a lifecycle basis, it is highly sensitive to real circumstances in fuel supply and combustion technology.
In the case of industries such as brick kilns, agro-processing, thermal power, and institutional energy, biomass combustion emits a large quantity of particulate matter (PM), carbon monoxide (CO), nitrogen oxides (NOx), and volatile organic compounds (VOCs). The literature supports the fact that the traditional combustion systems without the emission control emit 400–600 mg/Nm³ of PM and 350–500 mg/Nm³ of CO, which are higher than the standards and lead to air pollution in the ambient air and global climate change.
Apart from that, decreases in organic carbon usually released in the form of biomass smoke and shown to cool the air will automatically raise the net global warming impact of emissions unless controlled and regulated.

Why Real-World Biomass Emissions Testing is Necessary for Industry
Lab testing can’t replicate the actual-world complexity of commercial unit fuel burning. Fuel moisture level, firing temperature, burner setting, and load fluctuation factors significantly affect emissions results. Therefore, emissions testing must be done in-field. It provides accurate, real-time results under actual-world operating conditions results that are critical to:
- Regulatory Compliance: Industrial air emission compliance with CPCB and SPCB norms.
- Process Optimization: Identifying combustion inefficiencies and energy losses.
- Health and Safety Risk Assessment: Occupational and community exposure to contaminants quantification.
- Strategic Decision-Making: Ensuring investment in cleaner technologies and emission controls.
For instance, industrially verified biomass boiler design optimisation can reduce PM emissions by 60%, and fuel switching (raw wood to pellets or briquettes) can reduce CO emissions by 30–40%, based on controlled industrial tests.
The Importance of Experts in Industrial Emissions Testing
For environmental consultancies, regulatory agencies, and industries seeking quality information on biomass and solid fuel emissions, it is essential to work with certified environmental test firms. Accuracy in on-site emissions testing is important in order to guarantee compliance with international and national standards, which makes it easier to obtain quality data and useful interpretation.
Biomass and solid fuel emissions are a country-wide problem that crosses public health, industrial efficiency, and environmental sustainability. Science-based emission testing provides stakeholders firm ground upon which to proceed to cleaner processes and an environment in the future.
