DAVENTRY, U.K., Oct. 27, 2025 — With its disruptive technology, Residual Barrier Technology, or RBT, protects a wide range of industries and sectors, including healthcare, education facilities, food manufacturing and processing, restaurants, prisons, agriculture, public places, and commercial businesses.

Residual Barrier Technology Ltd, or RBT Global, putting life and our environment first, has developed a range of disinfectants and applications that have been independently and clinically tested over many years.

“We are changing the way we disinfect the world,” says Christine Brander, Executive Chair and Founder, Residual Barrier Technology.

Christine is at the heart of Residual Barrier Technology. Educated at Cranfield University and Director of the UK’s largest catering supplier, Christine now focuses her attention on finding an alternative way to protect us and our world from bacteria and infection.

Protectus products are independently proven to be effective at killing bacteria and viruses, whilst saving you time and money in application. Cost savings include reduced water usage and labour costs, no special storage requirements (non-flammable), less wear and corrosion, and more up time of expensive equipment. “Our products meet the vigorous demands of industry, healthcare, and food processing environments while still being suitable for domestic use,” says the company website.

“We utilise our scientific strengths to innovate new technology products that are less harsh to the environment,” says Adam Shay, CEO, RBT. Adam joined RBT in July 2022 to lead the business in its next stage of growth. A graduate of the Queensland University of Technology and Wharton Business School, Adam’s corporate experience spans more than 20 years, leading and growing businesses in Australia, the UK, Asia, and the US.

RBT’s Product Line, Foundation and Expansion

Key Offerings: RBT’s two flagship products, Protectus Air and the newly launched Protectus Aqua, are independently tested to kill 99.999 per cent of viruses, bacteria, and fungi while being 100 per cent biodegradable and safe for human and animal inhalation for up to 51 hours.

Protectus Air is a water-based disinfectant with three main ingredients, organic acids, the active ingredient, and a surfactant.

“Protectus Air is a powerful combination of nebuliser and airborne disinfectant. It is independently proven to be effective at killing bacteria, yeast, mould, and viruses, while saving you time and money in application. Cost savings include reduced water usage and labour costs, no special storage requirements (non-flammable), less wear and corrosion, and more up time of expensive equipment due to lasting efficacy,” says the RBT website.

Protectus Aqua is a water preservative that keeps animal drinking water in peak condition to promote gut health while simultaneously removing biofilm and algae, allowing drinking lines to remain clear.

Foundation and Expansion: RBT follows its core philosophy, which says, “The world needs a quantum leap in disinfectant technology. We are providing it.” Established in 2008, RBT is managed and run by the original founders, with financial backing and commercial assistance from a group of experienced private investors and supported by operational teams in production, warehousing, despatch, and finance.

After gaining early traction via AgriFutures growAG. and showcasing at evokeAG. 2025, UK-based startup Residual Barrier Technology (RBT) is preparing to enter the Australian market with two eco-friendly disinfectant solutions to help producers tackle airborne and waterborne pathogens.

RBT is no stranger to Australian shores. Since first listing its opportunity on AgriFutures growAG. in 2024, the UK biosecurity startup has visited three times, forged early connections with prospective partners and research groups, and built momentum since its second evokeAG. appearance.

Know More About RBT’s Global Presence

The system developed by RBT has seen favourable results in South African poultry operations, not only leading to an improvement in sanitation but also contributing to increased bird weight and reduced disinfection downtime, resulting in better yields and potential cost savings.

Protectus Aqua is a solution to another major on-farm challenge, biofilm. This invisible layer builds up inside water lines and harbours bacteria that can be transferred directly into livestock or crops. “If you don’t strip biofilm out of water pipes, the bacteria is transferred into the animal or onto the plant,” says Adam. “Protectus Aqua strips it out and stops it coming back.” The solution is neutral in taste and pH, automatically dosed, and safe for long-term use in livestock drinking systems.

Already used in poultry production, it is now being trialled in grain silos, targeting fungal threats like Aspergillus, Penicillium, and Fusarium. RBT sees potential applications across swine, ruminants, and post-harvest washing of fresh produce, particularly for growers seeking chlorine-free alternatives.

Protectus Air, RBT’s groundbreaking dry nebulising technology, simplifies disinfection protocols by safely emitting dry nebules into buildings, disinfecting both indoor surfaces and the air. It can be used while chickens and people are present. Designed to protect poultry health while minimising environmental impact, Protectus Air represents a significant advancement in the field, offering a biodegradable, cost-effective solution that promises to increase poultry farming output without compromising on biosecurity or sustainability.
