Herhof GmbH is a subsidiary of the Greek waste management company Helector S.A.. The majority position in Helector is held by the Greek conglomerate Ellaktor S.A.. Ellaktor S.A. is active in the areas of renewable energy and environmental technology. In addition it is a leader in the construction sector, real estate development and in privately-financed infrastructural projects. The publicly traded company ranks among the largest in Greece.

With this strong relationship as our foundation, we are in the position to design your project in an optimal manner with careful attention to all important details in the engineering, construction and operation stages. At the same time, we will customise our services to meet each customer’s special needs.


Helector S.A. is responsible for the sectors environment, energy and waste management in the Ellaktor S.A. Group. In this regard, Helector S.A. covers all areas of traditional waste management from waste collection to energy recovery. With the acquisition of Herhof GmbH in the year 2005, the product range has been extended by another promising field, the treatment of waste according to the Dry Stabilate® process. Since 2005, numerous activities have developed on the German market. Following this trend, a traditional holding company was founded with Helector Germany GmbH, in order to combine strategically the wide-ranging activities on the German market.

HELECTOR Germany GmbH is responsible for the administration and management of investments in companies in the sectors energy, plant engineering and construction, property administration as well as logistics and management services. Furthermore, Helector Germany GmbH will provide support for subordinated companies in the areas of public relations, marketing and administration.

Mr. Athanasios Katris, Mr. Yannis Kokotsis and Mr. Kostas Verganelakis are the managing directors of HELECTOR Germany GmbH.

Active Climate
Landfilling has always been a temporary solution and it cannot be justified eco-logically and economically. Valuable raw materials were taken away from the economic cycle and the consequential costs and ecological hazards were shifted to following generations. Herhof is committed to meeting this challenge.

In view of increasingly scarce fossil energy resources our Herhof technologies offer an outstanding commercial and ecological alternative. We promote the balance of nature through recirculation of its resources into the natural cycle. We use the Stabilat process to produce a storable and environment-friendly source of energy.

The use of Stabilat substitutes fossil fuels such as coal, crude oil and natural gas. Due to its high organic content, Stabilat releases 80% less CO2 during the energy production than conventional fuels.

As a result innovative waste management becomes an active climate protection measure.
Air, water, soil.
These are three elements that are worth thinking about innovatively and working for hard.

Protecting the environment and its resources is the main factor that links all our ideas and concepts. It is not only based on the Herhof Stabilat process, it is also the fundamental idea underlying all of our composting and biogas plants. The Herhof box composting system transforms organic waste quickly into nutrient-rich compost for farming or soil improvement in other areas.

When you use Herhof equipment to exploit waste for the production of energy or compost, the exhaust air is purified in the process – either with the LARA air treatment and air purification system or with biofilters. These filters do not only absorb dirt but odours as well. We always recycle condensation water as well as sewage and reutilise them.

The challenges of our time are the piles of waste and the fact that fossil energy resources will run irreversibly low within the next years.

At Herhof, we develop the efficient technologies to fulfil these challenges adequately. Our example in the process is taken from nature because nature knows no waste. Nothing has no value, everything is part of a cycle. Even what we throw away as being useless: “wastes” are high quality raw materials for energy production. And since every one of us generates new wastes day after day, we consider them as renewable energy source.

Herhof´s advanced technologies make it possible to recover recyclables or to produce compost and clean environmental friendly secondary fuels out of waste.
