OIO Group operates as an investment and development platform operating through its subsidiary, ESA, which is a waste management, treatment, and recycling company involved in the collection and recycling of hazardous and non-hazardous industrial waste from customers such as pharmaceutical, semiconductor, petrochemical, and electroplating companies. ESA currently has two revenue streams, from: (i) services income which is mainly comprised of the fees it charges its customers for waste collection and disposal services, which fees are similar to those charged by ESA's competitors, and (ii) the sales and trading of ESA's circular products that are made and processed from the recycled waste collected from its customers with respect to its waste collection and disposal services.
