Eden Research plc - Key patent granted for Eden’s Sustaine technology
("Eden" or "Company")
Key patent granted for Eden's Sustaine® technology
The patent is for "Encapsulation of High Potency Actives" allowing for the combination of Sustaine with a wide range of active ingredients from third parties. Sustaine microcapsules are naturally-derived, biodegradable micro-spheres produced from yeast extract, and are one of the few viable alternatives to plastic-based microencapsulation technologies which are used widely in fertilisers, encapsulated plant protection products (PPPs), seed coatings, and biocides.
Eden has engaged in a number of projects around the world to test the compatibility of Sustaine with third party active ingredients in order to determine whether benefits such as formulation stability, improved efficacy, dose reduction or resistance management can be achieved. In
In addition to being used to harness the benefit of nature-identical, terpene active ingredients in Eden's own commercial products such as Mevalone® and Cedroz™, the potential of Sustaine extends to the technology's effectiveness with other natural and synthetic compounds such as those widely used in Eden's key markets. This opens up a vast range of opportunities for the Company globally as pressure builds to cut out the use of plastic in the food supply chain. Many of the synthetic compounds used in agricultural products currently use microplastic encapsulation in their formulations which could be replaced with Sustaine. Regulatory steps are underway to phase out the use of these "intentionally-added" microplastics, as demonstrated by the

Eden's Sustaine® encapsulation technology harnesses the biocidal efficacy of naturally occurring chemicals produced by plants (terpenes) and can be used with both natural and synthetic compounds to enhance their performance and ease-of-use.
Sustaine microcapsules are naturally derived, plastic-free, biodegradable micro-spheres derived from yeast extract. They produce stabilised aqueous suspensions which, are easy to mix and apply, have phased release patterns, are safer for the environment and the crops themselves.
By 2025 in the EU, pesticides containing synthetic polymer microplastics are likely to be banned and removed from the market. The only acceptable alternative is the substitution with biodegradable formulations. Reformulated products will need to be evaluated and registered within the five-year transition period.
Sustaine is one of the only viable, proven and immediately registerable solutions to the microplastics problem in formulations requiring encapsulation.
Historically, terpenes have had limited commercial use in the agrochemical sector due to their volatility, phytotoxicity and poor solubility. Sustaine provides a unique, environmentally friendly solution to these problems and enables terpenes to be used as effective, low-risk agrochemicals.
Eden is developing these technologies through innovative research and a series of commercial production, marketing and distribution partnerships.
The Company has a number of patents and a pipeline of products at differing stages of development targeting specific areas of the global agrochemicals industry. To date, the Company has invested in the region of 14m in developing and protecting its intellectual property and seeking regulatory approval for products that rely upon the Company's technologies. Revenues earned by the Company have been modest whilst the Company has concentrated on securing patent protection for its intellectual property, gaining regulatory approvals, identifying suitable industrial partners, and entering into commercial agreements.
Mevalone® is a foliar fungicide which initially targets a key disease affecting grapes and other high-value fruit and vegetable crops. It is approved for sale in a number of key countries whilst Eden and its partners pursue regulatory clearance in new territories thereby growing Eden's addressable market globally.
Cedroz™ is a nematicide that targets free living nematodes which are parasitic worms that affect a wide range of high-value fruit and vegetable crops globally. Eden's commercial partner, Eastman Chemical, is pursuing registration and commercialisation of this important new product in numerous countries globally.
