The history of Gemidan


At that time only two percent of the garden waste in Denmark was being recycled, the rest was either sent to landfill or an incinerator. Gemidan A/S’s idea was to divert this resource from disposal by converting garden waste to a useful compost. Once this concept became established it developed further using mobile processing equipment that could compost garden waste close to where it was being generated. Therefore, it was no longer necessary to transport garden waste long distances for it to be composted.


Gemidan established the company, that today is known as Gemidan NMI AS.


Gemidan A/S expanded its business activities to pack waste for transport by land and sea. Operations were established outside Denmark and now the company operate facilities in many European countries.


Gemidan reaches another step, the first job of a complete outsourcing task is a reality with providing SRF/RDF.


The group expanded into providing site and operational management services to independent compost site owners creating a new business area. This expansion of composting operations increased the groups production tonnage of compost. New outlets and compost-based products were needed to ensure the compost produced could be put to good in agriculture. Gemidan gained environmental certification of ISO 14001.


Gemidan starts to export biomass to other countries. Staff numbers employed by Gemidan grew to 35.


Gemidan expands its activities through acquisition of other complementary businesses that together with Gemidan, expands and strengthens the strategic focus on sustainable solutions.

  • Gemidans buys a majority shareholding in SWS – Special Waste System.
  • Gemidan takes over the struggling company Komtek Miljø and continues to expand the groups various waste operations.
  •  Gemidan takes over an early pilot project to develop a new high-performance food waste pre-treatment technology for the biogas industry. From this early design concept was born ECOGI leading to a successful food waste processing recovery operation and the creation of a sales/engineering team to promote the worldwide sale of the ECOGI technology.


Gemidan buys the operations of Tulstrup Kompost to provide local garden waste composting services on Zealand (Sjælland). In collaboration with Geminor, a company part owned by Gemidan, we start the importation of RDF waste to the danish incinerators. This new service offering began with a new environmentally approved handling facility at Lindø harbour.


A 100% owned subsidiary Gemidan Ecogi A/S was created to provide an independent focus to develop and market the ECOGI food waste pre-treatment technology. The ambition being to sell the ECOGI technology in both in Denmark and across the world worldwide. A UK based company Gemidan Ltd was also created to support both the import of RDF and the Ecogi sales activities in the UK.


Gemidan creates a new Trading Department to offer customers a complete waste/resource handling and distribution service to promote an experience based on an approach of ‘from cradle to cradle’. The strategic focus being a sustainable solution where distribution and waste treatment are optimised.


The first independently owned Ecogi food waste pre-treatment facility is established by Affald+ in Næstved (Denmark).


Gemidan establishes a new administration centre in Schwerin, Germany to address the changing market forces within the waste industry in Europe. The pulp-based substrate produced by the Ecogi pre-treatment technology gains ISCC approval.

Investment, establishment and opening of Gemidan Ecogi Frederikshavn A/S


To provide a greater strategic focus on independent sustainable solutions Gemidan Group decide to sell its part ownership in Geminor.

Investment, establishment and opening of Gemidan Egedal A/S in January 2021 and thus a nationwide with treatment facilities on Zealand and Jutland.
