Legislative Compliance
Generally speaking the only legislation that affects our products is through communications platforms and ATEX ratings and their equivalent. This is becoming a more and more standard solution across the world. Generally our products are enablers and often allow or create compliance rather than needing to adhere.
Metasphere does not act as a consultancy to overseas governments on legislation unless on matters of telemetry, we could assist in terms of data protocols as we do in the UK through the Water Industry Telemetry Standard (WITS).

INSTITUTE OF ROSES AND ESSENTIAL OIL CROPS: The beginning was initiated in 1907. Despite the numerous reorganizations, the Institute has grown from a small experimental field to a leading scientific unit in essential oil production. The idea for the creation of an experimental station of roses in the town of Kazanlak dates back to 1906. It was discussed during the First Conference on Rose Oil Production in Plovdiv and the following decision was made: "To ask the government to establish experimental fields where all issues connected with the cultivation of roses and other aromatic plants will be studied".  In 1907 the Ministry of Commerce and Agriculture allocated 26 decares from the state fruit-tree nursery in Kazanlak to plant the oil-bearing roses and other aromatic plants brought from France. So under the management of Konstantin Malkov the scientific research work on roses and essential oil crops was started in Bulgaria. Following the extension of the experimental field in 1925, a meteorological station was built. In 1928 two modern distillation stills were installed. A laboratory was created to research diseases and pests on roses and essential oil crops. Library activities were initiated. A significant part of the Institute's activities is connected with the technology of processing essential oil and medical plants. The Institute of Roses and Essential Oil Crops has undergone a number of changes in its structure and research fields during it development. Nevertheless, it has remained the main centre for research, application, service and support in the field of essential oil and medical plants in Bulgaria.
