The new contract concerns the annual management of 300,000 tons of municipal waste, of which 100,000 tons will be pre-sorted organic waste. Specifically, the Plant, after the completion of the modifications for its upgrade to a Green Factory (completion within 2023), will be able to process the following streams:
- Municipal Mixed/Residual Mixed Municipal Solid Waste (MSW)
The MSW that will be received and treated by the Plant will be the mixed-residual, mixed municipal waste stored in the network of bins or in other temporary storage means, as provided by the municipal waste collection vehicles. The quantities to be processed will be up to 200,000 tons/year and will be treated on two (2) of three (3) identical processing lines in the Mechanical Sorting Department.
- Pre-sorted Bio-waste
It includes the reception and treatment – composting of pre-sorted Bio-waste which will be collected from the municipal separate collection networks (“brown bin”) and from the street markets. The quantity to be treated will be 60,000 tons/year.
- Green Waste-Pruning Waste, which is required for composting the biodegradable fraction of mixed- residual waste and pre-sorted Bio-waste. The quantity to be processed will be 40,000 tons/ year. In addition to the above, the Plant will accept additional green waste – pruning from 20,000 to 35,000 tons/ year which will be provided by the municipalities and managed at the Plant.

/ HELECTOR
HELECTOR is the leader in the field of Hazardous Medical Waste Management (HMWM), as it has constructed and operates since 2002, the only Medical Waste Incineration Plant (MWIP) in Greece, located in the Sanitary Landfill area in Ano Liossia. The owner of the project is the Special Inter-Collective Association of the Prefecture of Attica (EDSNA).
The plant at Ano Liossia is the first and the only licensed incineration facility for hospital waste currently in operation in Greece. Applying the latest technology and the best available techniques, the plant successfully receives and manages 4,000 tons of waste per year, from 1,800 medical unit points around Greece (hospitals, clinics, clinical laboratories, doctors’ private practice, dental clinics, veterinary clinics and pharmaceutical warehouses).
The highly trained personnel are ready to respond to the most demanding projects, such as the management of highly infectious waste, as well as all types of toxic waste.
The facility has a daily capacity of 30 tons, 2 independent incineration lines, temporary storage cooling chambers, internal wastewater management, a radiation control gate and a continuous monitoring system of exhaust gases. The 24-hour operation of the incineration plant ensures the lawful destruction of all collected waste within a short period and the provision of the necessary documents, such as full destruction certificates from the disposal facility within a few days.
Incineration is a treatment process that achieves:
- Complete Destruction of waste at temperatures above 1100 ºC.
- Complete destruction of infectious and toxic nature of the waste.
- Complete destruction of the commercial value of drug waste.
- Radioactivity control.
- Integrated waste management.
- 70% volume reduction.
- Principle of proximity.
It should be stressed that the main objective of the employees and management of the plant is to protect public health and the environment by promoting transparency and sustainability.
It is noted that, since August 2022, the concession contract of EDSNA’s Medical Waste Incineration Plant was signed and its operation for the next 23 years has been undertaken by EPALTHEA SA in which HELECTOR participates with 60%.

STAINABLE ENVIRONMENTAL TECHNOLOGIES
Nature – our model
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. 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.
HELECTOR´s advanced technologies make it possible to recover recyclables or to produce compost and clean environmental friendly secondary fuels out of waste.
Aerobic Waste Treatment
The volume of residual waste is organically reduced through dewatering. At the end, the water content lies distinctly below 15 percent, which significantly improves the mechanical separability of the material. This distinguishes Herhof’s Stabilat® process from all other conventional treatment techniques. Reusable material is separated during the process and can be sold as a genuine high-quality raw material and returned into the material cycle. The remaining organic waste fraction is pressed into hygienic, nearly odour-free energy resources known as pellets.
- Processing
Extraneous matter and harmful substances are removed from the waste and the latter is then shredded to a maximum grain size of 250 mm and then transported via a fully-automatic crane system into the Herhof bio box.
- Stabilisation
In the Herhof bio box, the waste is dewatered through biological means. This is the vital step to the subsequent pure source separated break down of the waste mixture into reusable material and energy as well as for the storability of the fuel generated.
- Inert separation
This means the removal of the mineral fraction (stones, glass, ceramics) and the metals, separated into ferrous and non-ferrous metals.
Anaerobic Waste Treatment – Biogas process
Steps of the process:
Process sequences are represented in diagram format in the flowchart below. The essential elements of the process are dry fermentation for fermentation of solid organic substances by batch and continuous fermentation in the process water reservoir through nutrient movement in the process water reservoir circuit.
The steps of the process are further described in our video clip of the plant in Heppenheim
Herhof-Anlage-Heppenheim-Video.jpg
- Substrate preparation
Preparation of substrates if necessary (e.g. pulverization, mixing etc. depending on the substrates)
- Placing the substrates
Placing the substrates in the empty dry fermenter
- Pre-aeration
Optional pre-aeration in the closed dry fermenter to increase the temperature
- Anaerobic processing
Anaerobic processing by means of percolation with process water
- Post-aeration
Expulsion of biogases, aerification of digestate, odour removal
Optional aerobic post-processing to reduce water content
- Removal
Removal of digestate
- Post-treatment
Post-treatment of fermentation residue (e.g. hygienisation in Herhof boxes or maturation, screening etc. depending on the application)
Wet fermentation
The wet fermentation technology widely used up to this point, which was designed essentially for fermentation of liquid manure, reaches the limits imposed by the process at DS (dry substance) contents greater than 15%. The reason for this is essentially that the substrate is increasingly difficult to agitate and pump. In addition the wear out of aggregates increases with higher dry substances. By contrast, there is no upper limit for DS content in dry fermentation based on our process. The substrate and fermentation residue are brought in and removed in solid, stackable form. Our plants consist of two main plant sections in which organic substances are simultaneously converted into biogas, dry fermenters and a process water tank. There is in addition a delivery area and a part of the plant designed for use of the biogas that is produced (for example a combined heat and power unit (CHP) or gas supply) as well as further plant sections.
Dry fermentation
Moisture content | Percolate
Dry fermentation also requires a moist environment for fermentation. In our process, this environment is created and maintained by controlled sprinkling of the substrate in dry fermenters with conditioned process water, which is guided through a circuit.
Continuous supply of the biogas utilisation
In order to supply continuously the CHP or gas cleaning/feeding system with sufficient biogas, multiple dry fermenters must be operated in parallel but staggered in time.
Effective biogas production
The dry fermenters as well as the process water tank conduct to the biogas production. The intensive percolation rate and the high-volume of the process water tank are the effective regulation items of the biogas production. With the help of these items the bacteria and the needed energy is brought into the substrate in the beginning of the process. Hence the hydrolysis is strated.
Development of a system
Further levelling is achieved by biogas production which occurs continuously in the process water reservoir. For minimizing the emissions and to optimizing the usage of the produced biogas we have developed a system, which secures the collection and treatment of the weak gas in the end of each fermentation cycle.
The advantages of dry fermentation compared to wet fermentation may be summarized as follows:
- Significantly lower water requirement and no mashing necessary
- Lower process energy requirement (no mixing mechanism necessary)
- Less material wear due to fewer movable machine parts
- Less susceptibility to detrimental substances and overacidification
- Usually lower sulphur content in the gas, which has a positive effect on the service life of the CHP Smaller digesters due to higher energy contents of the substrates that are used
- Synergy in the use of agricultural equipment (e.g. wheel loaders, tractors, mixing carriages, manure spreaders, etc.)
- Simpler (stackable) storage of fermentation residue.
- Our process offers the following advantages compared to other dry fermentation processes:
- Control and measurement system for every single fermenter
- Weak gas management system
- Optimum biogas yield with short delay time
- Less investment costs (no mixing of substrates needed) Minimum internal electrical and thermal energy need (no heating of dry fermenters, weak gas management system, no excess water and no mixing of substrates required
- Homogeneous percolation and optimised process conditions through percolation and high-volume process water tankLow methane emissions and homogeneous aerification of fermentation residue pile with special aeration system
- Low methane emissions and homogeneous aerification of fermentation residue pile with special aeration system
- Low variations in gas production through simultaneous production of biogas in process water tan
Waste To Energy
Generating energy from waste and residues
By the term waste to energy, we mean recycling of energy from waste and residual material. Household and industrial waste as well as biomass is suitable for the process.
The new EC guideline 1999/31/EC was already put into national law in Germany in June 2005. This made the subject waste to energy become more important. Ever since then, only pre-processed waste such as residual material from waste incineration or from waste fermentation can be disposed of permanently in landfill sites. For communities and business establishments which produce huge quantities of waste, the need to look for alternative possibilities of disposal created a big challenge.
From Energy recovery from waste …
… there are now a few thermal processes for waste treatment. They all have the aim of extracting energy from residual material. The quality however depends on the respective flexibility and energy efficiency.
With the Herhof Stabilat® …
… we produce a storable substitute fuel that can be used in a flexible manner both temporally and spatially. Always and anywhere where energy is needed.
Separation and sorting technology
Apart from the concept and implementation of a complete system for the processing of household waste, we offer you tailor-made systems for waste separation and sorting.
This area of operations combines conveyor and shredding systems; separation units according to the specific weight of the materials; screening systems; ferrous and non-ferrous metal separators; inert material processing (separation of metals, very ferrous and non-ferrous fractions as well as extraneous materials such as batteries or electronic scrap, for example).
Based on your specifications, we will combine the individual units in order to achieve the best separation and sorting results for you.
