Effective Microorganism (EM) Technology
EM (Effective Microorganisms) is an innovative solution composed of microbiological preparations that include live cultures of lactic acid bacteria, yeasts, phototrophic bacteria, actinobacteria, fungi, and other beneficial microorganisms. These natural elements act synergistically, restoring the balance of environments and promoting health in an efficient and sustainable way.
Furthermore, EM technology has a wide range of applications that, in turn, help solve some of today's biggest environmental and health challenges. Therefore, by using EM®, it is possible to achieve effective results in promoting environmental and human well-being, while adopting a more sustainable approach.
- EM technology offers several solutions, such as revitalizing degraded soils, restoring their productive capacity and recreating the humus layer, essential for healthy plant growth. In addition, it contributes to water purification and the optimization of sewage treatment systems, promoting natural solutions for environmental preservation.
- In addition to these applications, EM also improves animal welfare by neutralizing odors and creating healthier and more pleasant environments. Finally, it offers household solutions, such as natural cleaning products, that not only eliminate odors but also help control the growth of dust mites, providing a cleaner and healthier home environment.

Additionally, EM® technology has expanded into areas such as cosmetics and health care, offering natural and effective alternatives for those looking for products that combine well-being and sustainability.
With EM, With us, you have access not only to practical and innovative solutions for your daily life, but also the opportunity to contribute to a healthier and more sustainable future.
Professor Teruo Higa

Professor Teruo Higa, from Okinawa, created Effective Microorganisms (EM). The idea arose while he was conducting research on oranges for his doctoral thesis in horticulture at Kyushu University. It was during this period that Higa discovered the potential of microorganisms in agriculture, directing his research in a new direction. His investigations into the use of heterogeneous mixtures of microorganisms in plant cultivation soon expanded to other areas, such as livestock farming, environmental regeneration, and human health. All microorganisms present in EM preparations come from natural environments and are not genetically modified.
Professor Teruo Higa was born in Okinawa, Japan, in 1941. He graduated from the University of the Ryukyu Islands and obtained his doctorate in horticulture from Kyushu University. In 1982, he received the title of professor at his home university. His research on effective microorganisms and the development of EM technology have earned him international recognition.
