Which Industries Should Be Considering Process Analytics for Gas and Liquid Waste?
6 August 2025
In an era where environmental accountability and operational efficiency are no longer optional, process analytics is fast becoming a critical tool—not just for product optimisation, but for managing waste streams. For many industries, gas and liquid waste isn’t just a by-product—it’s a regulatory, reputational, and financial risk.
So, which sectors should be taking this more seriously? The short answer: any industry with complex processes and measurable emissions. But some sectors stand out as overdue for a strategic rethink.
Chemical Manufacturing
From bulk petrochemicals to specialty compounds, chemical plants generate volatile organic compounds (VOCs), liquid effluents, and potentially hazardous waste. With tightening global regulations, real-time analytics of gas emissions and wastewater composition is vital—not just to stay compliant, but to uncover inefficiencies that are literally going down the drain.
Why it matters:
- VOC thresholds are under increasing scrutiny -https://www.gov.uk/guidance/control-and-monitor-emissions-for-your-environmental-permit#volatile-organic-compounds-vocs
- Many plants still rely on lagging lab results instead of real-time data
- Small process leaks can equate to massive annual losses
Pharmaceuticals
The pharmaceutical industry is highly regulated, yet many facilities still treat waste stream analysis as an afterthought. From solvent recovery to biologically active waste in water, real-time insight can not only reduce environmental impact but help safeguard IP and reputation.
Why it matters:
- Regulatory non-compliance can lead to batch rejections or shutdowns
- Liquid waste from API (Active Pharmaceutical Ingredient) processes often contains valuable materials
- Data integrity is paramount—inline analytics strengthens audit trails
Food & Beverage Processing
Water is integral to nearly every F&B process, from cleaning and cooking to fermentation and packaging. Yet the management of liquid waste—including wash water, oils, sugars, and organics—remains surprisingly manual in many plants.
Why it matters:
- Waste discharge fees are rising across many regions
- Poor water quality or contamination can lead to production halts
- Inline analytics supports water reuse and circular processing initiatives
Oil & Gas
Despite its long-standing use of analytical technologies, parts of the oil and gas sector still rely heavily on manual sampling and lab analysis for flare gas monitoring, produced water, and vapour emissions. In a climate-conscious market, that’s no longer defensible.
Why it matters:
- Real-time data is critical for emissions reporting and carbon accounting
- Waste gas can often be recovered or repurposed if properly analysed
- Environmental penalties and ESG scrutiny are only increasing
Pulp & Paper
The pulp and paper industry is water-intensive, producing large volumes of effluent containing fibres, lignin, chemicals, and heat. Without real-time monitoring, discharge management is reactive rather than strategic.
Why it matters:
- Many facilities are located near protected waterways
- Energy recovery from waste streams is increasingly viable
- Inline analytics supports closed-loop water systems
Mining and Metals
From tailings ponds to acid mine drainage, the mining sector generates highly variable liquid and gaseous waste streams that can be toxic and environmentally damaging. The cost of poor monitoring isn’t just regulatory—it can be catastrophic for communities and ecosystems.
Why it matters:
- Public and investor pressure is mounting for responsible mining
- Regulatory bodies demand more transparency and traceability
- Process analytics enables real-time mitigation of contamination events
The Bigger Picture: Process Analytics as a Strategic Differentiator
Process analytics isn’t just a compliance checkbox—it’s a source of competitive advantage. By adopting continuous monitoring of gas and liquid waste, industries can unlock:
- More predictable operations
- Lower treatment costs
- Higher resource recovery
- And critically, stronger ESG credentials
In a world shifting toward net-zero and circular economy models, the ability to prove environmental performance—backed by real-time, tamper-proof data—is fast becoming a strategic necessity.
Bottom line?
If your plant handles liquid or gas waste—and your industry is under regulatory, investor or public pressure—then you should be considering process analytics not as an upgrade, but as a requirement for future viability.
