Chemical-free water treatment is not just operationally superior — it is inherently more sustainable. Here is why.
Conventional hydrogen peroxide is produced at large centralised manufacturing facilities — typically using the anthraquinone oxidation (AO) process, which is energy-intensive and produces hazardous by-products. The resulting concentrated product (35–70% H₂O₂) must then be transported, often over long distances, in specialised tankers.
Each step in this chain carries a sustainability cost: production emissions, transport emissions, packaging waste, and chemical residuals in discharge. By the time hydrogen peroxide arrives at the point of use, it has accumulated a significant carbon and environmental footprint before a single litre of water has been treated.
Onsite peroxide generation improves environmental performance across the full lifecycle of water treatment — not just at the point of use.
Onsite generation eliminates the need for synthetic chemical additives in water treatment — and the associated environmental burden of producing, transporting and disposing of those chemicals. No persistent chemical residuals enter waterways or soils.
By generating hydrogen peroxide on-site, all transport-related emissions are eliminated. When powered by renewable electricity, the process achieves net-zero carbon for the oxidant generation step itself. HPNow systems offset up to 3 tonnes COâ‚‚ equivalent per tonne of Hâ‚‚Oâ‚‚ produced, compared to conventional supply chains.
Because Peroxide UltraPure™ breaks down entirely to water and oxygen after use, treated water can be safely reused or discharged without chemical decontamination steps. This supports circular water management — reducing freshwater draw and enabling closed-loop industrial processes.
Tightening regulations on chemical discharge — from PFAS restrictions to cooling tower blowdown rules (42.BImSchV in Germany, BG 89 in the UK) — are making conventional chemical programmes increasingly difficult to defend. Onsite peroxide generation produces no regulated chemical discharge, simplifying compliance and future-proofing operations.
HPNow's technology directly supports organisations in meeting their obligations under major sustainability reporting frameworks — providing measurable, documented improvements in water and emissions metrics.
HPNow's sustainability credentials have been validated by independent bodies — giving customers confidence that the environmental claims are robust and externally verified.
Chemical water treatment faces growing regulatory pressure globally. Onsite peroxide generation is well-positioned to meet and exceed emerging requirements.
Mandatory regulation for Legionella risk management in cooling towers. Requires documented, effective biocide treatment. Chemical-free alternatives like onsite Hâ‚‚Oâ‚‚ generation are increasingly favoured as they eliminate regulated chemical discharge concerns.
Upcoming UK guidance covering chemical-free cooling tower water treatment systems. HPNow's approach aligns directly with the direction of these emerging guidelines, reducing compliance risk for operators transitioning away from synthetic chemical programmes.
Restrictions on per- and polyfluoroalkyl substances (PFAS) used in many legacy water treatment chemicals are tightening across the EU and multiple US states. Onsite peroxide generation contains no PFAS compounds — eliminating this regulatory exposure entirely.
