A new approach to one of the world's most persistent problems

• Biofilms are organised communities of bacteria encased in a protective, slimy matrix. Forming a biofilm is one of bacteria’s most effective survival strategies — within the matrix, bacteria can be up to 1,000 times more resistant to antibiotics and disinfectants than free-floating counterparts.

• The hidden threat right under our nose

  Biofilms are everywhere — lurking in home drains and sinks, coating the interiors of cooling towers, fouling industrial pipes, contaminating water treatment systems, accumulating in food-processing equipment, and forming inside medical devices. What appears to be a simple “slimy layer” is actually a sophisticated bacterial city with organised neighbourhoods, communication networks, and defence systems.

  How biofilms form and persist

  Bacteria don’t simply adhere to surfaces at random. They follow a multi-step process:

  • Attachment — individual bacteria adhere to a surface.

  • Maturation — complex 3D structures develop, with channels for nutrient flow and a slimy, impermeable protective covering.

  • Dispersal — when nutrients run low, or bacteria detect a new location to colonise, the protective covering briefly opens, allowing a group of bacteria to depart.

  This protective covering acts like a fortress wall, blocking disinfectants, cleaning agents, and antibiotics from reaching the bacteria within. This is why biofilm contamination is so stubborn and difficult to treat — and why simply killing the bacteria rarely solves the problem.

Biofilms are among the most pressing challenges facing industries and households worldwide. Their resistance to conventional treatments makes them a US$4–5 trillion global problem, spanning health, food and water security, energy, and industrial systems.

🏭 Industrial water systems

Biofilms colonise cooling towers, process water lines, and water treatment infrastructure — driving fouling, reducing efficiency, and creating contamination risks that conventional disinfectants repeatedly fail to eliminate.

🍽️ Food and beverage production

Persistent biofilms on food-processing equipment are a major source of contamination, leading to product recalls, costly downtime, and public health risks — despite intensive cleaning.

💧 Water treatment and reuse

Biofilms in treatment facilities can harbour pathogens, reduce system efficiency, and compromise water supply safety — threatening public health and inflating operational costs.

🏠 Homes and domestic plumbing

Biofilms thrive in household drains and traps — a persistent reservoir that ordinary cleaning products can mask but not eliminate. The same biology that causes industrial failures also drives recurring odours, blockages, and contamination risks in domestic settings.

The treatment gap

Current approaches all have significant limitations.

• Chemical disinfectants — only the free-floating bacteria around a biofilm are reached. The protective matrix blocks them from reaching the bacteria inside, so the biofilm itself survives and continues to grow.

• Physical removal — labour-intensive, temporary, and often incomplete.

• High-dose solutions are environmentally damaging and encourage resistance.

• Heat or UV — not suitable for many applications, and don’t actually work on established biofilms.

The need for innovation

The biofilm matrix is why every existing solution falls short. A new solution category is needed — one built to address the matrix, not work around it.

We have identified a first-in-class anti-biofilm activity — a nature-derived compound that disperses biofilms by targeting the protective matrix that conventional treatments cannot penetrate.

The discovery was made through a systematic screening programme. We've now developed a reliable method to produce the activity and to observe its effect on established biofilms under real-world conditions.

Intellectual property is being prepared.

Biofilms cause the most damage where they occur most: in water. Cooling, process, treatment, drinking, and drainage water — these are the environments where biofilms grow fastest, regrow most aggressively, and cost industries and households the most to control. Utilium acts directly in water-contact environments, where conventional cleaning chemistry repeatedly fails to remove the biofilm itself. The water-contact biofilm market is one of the largest unsolved opportunities in industrial and consumer chemistry, with annual losses measured in trillions of dollars across every water-using industry on earth.

🏭 Industrial water systems

• Cooling towers, process water lines, and heat exchangers across power generation, mining, manufacturing, and oil & gas share the same enemy — biofilm fouling that reduces efficiency, accelerates equipment wear, and shelters microbial communities that biocide programmes cannot reach. Utilium offers a different mode of action for operators tired of running the same biocide cycle and seeing the same regrowth.

🍽️ Food and beverage production

• Beverage lines, drainage systems and processing equipment with continuous or recirculating water flow are sites where biofilms persist despite intensive cleaning regimes — forming in seals, joints, valves, and dead legs where cleaning chemistry can’t reliably reach. The cost is measured in product recalls, line downtime, and the constant pressure of microbial audit risk.

💧 Water treatment and reuse

• Biofilms in treatment plants, holding tanks, distribution systems, and purification infrastructure can shelter pathogens, reduce filter efficiency, and undermine the safety of water supplies. As pressure grows on water reuse and the volume of treated and purified water continues to rise, the operational cost of biofilm contamination is increasing. Utilium offers a way to address biofilms directly, rather than chasing downstream symptoms.

🏠 Homes and domestic plumbing

• Drains, traps, and household water systems are the largest hidden reservoirs of biofilm in the country — and the source of post-surgical infections, blockages, and recurring contamination that no consumer cleaning product fully resolves. Utilium’s mechanism offers a route to genuine domestic biofilm control in a market where every household is a potential customer.
