Združenie Energy 21

Energy 21 is a Slovak association founded in 2015 that supports sustainable energy solutions, with a focus on bioenergy, research and innovation, and the efficient use of renewable resources. Its work brings together experts, institutions, and companies to advance applied research, environmental responsibility, and practical approaches to a more sustainable future.

The association participates in research projects and shares specialist knowledge through media articles and publications. Its activities have included research into the use of coffee waste, methods for isolating phytosterols from corn oil, and the development of biofuels and bio-based raw materials. Energy 21 also supports projects that connect research with everyday sustainability. Through Prilejolej.sk, it promotes the responsible collection of used cooking oil from households and restaurants, helping people dispose of this waste in an environmentally conscious way.

The organization provides information about its projects, research, members, and certification activities, and works through partnerships to encourage innovation and the practical application of renewable-resource solutions.
