Herborn GmbH is a middle-class enterprise based in Ginsheim-Gustavsburg, Germany, with subsidiaries in Switzerland, France and Brazil.
Since 1985 we have been developing and producing mobile and stationary systems for recycling discharge lamps containing harmful substances at our German site.
Beginning with the development of the first generation of our lamp-recycling method "system herborn" between 1985 and 1988 and the launch of the first system in 1988, we have used "system herborn" to process safely and efficiently over 150 million mercury contained lamps in Germany, Austria, the Netherlands, Luxemburg, France and Switzerland. During this period we have become one of the leading providers in this sector – on a national as well as international scale.
The resulting experience as well as the continuous further development and improvement of our method by our engineers have led to the creation of the most progressive, economical and environmentally friendly technology in the field of lamp recycling.

| We are regularly monitored by the Technical Inspection Authority (TÜV, etc.) The patented mobile and stationary lamp recycling method "system herborn" ensures a professional, environmentally friendly and economical recycling of discharge lamps containing harmful substances, outmatching by far the regulations imposed by law. The detailed recycling process: Via an automatic separating unit the fluorescent tubes are fed to the insulated reception system of the recycling unit, are counted by sensors, and their processing measurements are imported into the controller. In the recycling-system types 3rd generation (cap-separation method "system herborn"), the metal caps are separated mechanically in a dry process at rated break points from the glass body, the lamp glass is broken and the fluorescent powder is sucked off. Using this method, it is not necessary to sort the linear fluorescent lamps according to their length and diameter. In 4th generation system types (cap-separation/air-push method "system herborn")(patented), the caps are thermally separated from the lamp body and the tubes blown clean. If necessary, this technology can be complemented by optical detection of the fluorescent powders used in the lamp through image processing (patented). With this method, it is possible to allocate the lamps to their manufacturer and to extract the different fluorescent powders separately for later reutilisation in new lamps. After the separation of materials the main components of the fluorescent tube undergo a thermal treatment in order to minimise the adhering amount of remaining mercury. In order to ensure a high quality of the lamps´ end caps, they are cleansed in a single processing step from still adhering material and from the remaining mercury-infected stem glass (lead glass) and lead wires. An additional step to ensure premium quality is a computerised thermal after-treatment of the secondary materials. The technical conception and computerised control of the system working under negative pressure ensure that no harmful substances can get into the environment at any time. The entire process air is fed to the working and lamp collection section, so that the harmful substances generated there are sucked off by the working section and fed into the system. The intoxicated air is led through filter systems and, after undergoing a sophisticated process, cleansed by an activated-carbon filter. This technological principle is groundbreaking for the recycling of lamps and is used successfully by Herborn in several countries. Herborn provides an overall concept for the disposal of discharge lamps, designed to meet the individual demands of the customer and the respective country | |
