About Zayndu

Zayndu’s seed treatment and priming process harnesses cold plasma to create ActivatedAir™, the world’s first application of this technology on seeds. It maximises profits for controlled-environment agriculture growers by increasing yields and speeding up growing cycles.
ActivatedAir™ eliminates seed-borne pathogens, stopping them from contaminating growing facilities and reducing seedling diseases like damping off. It also kick-starts the seed’s metabolic processes, effectively priming it for sowing.

The idea for Zayndu came from collaborative work by Dr Felipe Iza’s research group at Loughborough University and industrial partners - who identified a growing unmet need for sustainable seed treatments that delivered increased productivity and plant health.

To exploit this opportunity, Zayndu was formed in 2019, and Ralph Weir was brought in to head up the company as CEO. A proof of concept was tested and established, and now ActivatedAirTM is fully commercially available.

Presently, ActivatedAir™ is being used by some of the biggest and most sophisticated vertical farms in the world, as well as more traditional greenhouses. The most common crops are leafy greens and micro greens, but the team has experience with a wide range of crops beyond these.

The Team

Ralph Weir

Chief Executive

Ralph is a successful growth and early-stage serial entrepreneur, with experience in creating compelling strategies and vision, tracking, evaluating and adapting to shifting markets, building, managing and motivating high performance teams, and leading sales growth domestically and on the global stage. His focus is on building relationships with potential users and future investors.

Felipe Iza

Technical Director

Felipe is a founder of the business and an internationally-recognised specialist in cold plasma technology. His expertise in high-voltage and high-frequency electronics design spawned the unique plasma systems at the core of the Zayndu products, and will be critical in addressing the static electricity issues. His role will be to guide the overall program at Zayndu, providing input to both the electromechanical and biological development programs.

Alberto Campanaro

Head of Plant Science

Alberto is an experienced plant scientist. His Ph.D. (Durham University) investigated molecular responses underpinning plant immune responses. Prior to Zayndu, he held post-doctoral research roles at Durham, investigating the molecular interactions regulating the growth-immunity balance in plants in collaboration with Agritech leaders such as KWS, ADAS, BASF; his role is to co-ordinate the plant science team and lead the development of the seed treatment protocols.

Applications for the Zayndu Seed Health Treatment System

Imagine a process which boosts germination - not just accelerating it, but driving germination rates skywards.  Imagine if that process improved the synchronisation of germination, so all your seeds germinated with a nice tight window - resulting in harvesting plants which are consistent in size and maturity.  Now imagine if that system delivered healthier seeds, giving the power to resist pathogen attacks.

That is what the Zayndu system delivers.  Seeds are "vitalized" with cold plasma.  It improves their health, which ultimately yields to enhanced crop yield.  Cold plasma is described as "the power of lightning" - it is in fact an incredibly low-power process which emulates the effect lightning has on air, creating conditions that are highly beneficial to seeds.

The use of cold plasma is gaining interest as a low energy, low carbon technology to replace the use of fossil fuels and chemicals in many areas of agriculture. Zayndu’s systems are at the forefront of the ‘Plasma Agriculture’ revolution.

Join the team

Zayndu is a fast-growing, dynamic team, developing exciting technologies. We foster a can-do attitude, and, as a small company growing fast, we offer opportunities – whether that be personal growth, the chance to work in unusual environments – or just the challenge of doing something that’s never been done before, of pushing boundaries, and of course – eliminating toxic chemicals.
