Joma specializes in titania nanoparticles and photocatalysis, and in developing and producing nano-TiO2 based products for self-cleaning and anti-pollution. We have created a unique nanoparticle, with a patented and scalable production process, for the self-cleaning treatment of concrete surfaces in urban areas. This is the key component of our products for concrete surface treatment, consisting of water-based dispersions of TiO2 nanoparticles with self-cleaning potential, by photocatalysis alone, and offering a non-toxic surface coating for the treatment of concrete. Our nano treatment has a superior performance in making surfaces photocatalytic, breaking and preventing the growth of organic matter (bacteria, fungi and algae) and degrading NOx gases. It represents a steep technological breakthrough from existing alternatives providing a sizeable set of advantages: 35% higher photocatalytic activity; unique surface structure that helps adsorbing certain species on the particle; and higher selectivity and more efficient breakdown of NO2 with less intermediate products being released. In addition, it represents cost savings of 67% compared to non-treated surfaces and of 56% compared to conventional self-cleaning coating products. Notably, the cost of Joma’s products and respective application is less than the cost of one professional cleaning, meaning that the investment is typically returned in 1-2 years. The greatest challenges for our company to establish and participate in the SME Instrument Phase 2 project are related to the expertise and capacity required for the industrial testing, production scale up and post-production steps/activities. These will be overcome and mitigated by third parties subcontracting and further expansion of the team during the Phase 2 project. As the project will be fully managed by Joma, with external agents supporting the customer identification and contact, we are confident that we will be fully capable to fulfil these objectives.
