Ammonia (NH3)
A chemical compound of nitrogen and hydrogen that is used to make fertilisers and dyes.
Ammonium sulphate (NH4)2SO4
Inorganic compound from the nitrogen fertiliser family. Nitrogen is considered the plant world's engine.
Ammonium sulphate is a high quality, concentrated fertiliser additive that can be added to the soil according to need, i.e. producing a balanced level of nitrogen in the soil.
Biogas plant
Facility for generating biogas from organic material, including all the equipment and buildings for storing, recycling and continued usage. Biogas is generated when biomass ferments.
Calcium carbonate (CaCO3)
Used as fertiliser, this mineral supplies plants with calcium and stabilises the pH value of the soil. These attributes make it an extremely important material for agriculture and forestry.
Calcium carbonate is also used in manufacturing paper, producing plastics, in construction materials, paints and varnishes, as well as in environmental protection.
Carbon dioxide (CO2)
Chemical compound of carbon and oxygen whose concentration in the atmosphere primarily has natural causes. Above all, the increasing combustion of carbon-rich substances leads to a significant increase in CO2 and therefore to an acceleration of the greenhouse effect.
CHP bonus
Is a tariff guaranteed by the German government for an eco-friendly heat concept in a biogas plant, as defined by the stipulations of the German Renewable Energies Act (01.01.2009). This heat concept must be certified by two totally separate tests carried out by an environmental expert.
If the requirements are fulfilled, the grid operator must pay €0.03 for each kWh fed in.
Combined Heat and Power Plant - CHP
The purpose of the combined heat and power plant is to use the gas produced as energy. It consists of a combustion engine, generator and heat exchange system.
CHP - combined heat and power
Combined heat and power. Simultaneous generation of electricity and heat in a power station, or combined heat and power plant (CHP).
Distribution of digestate
In Germany, digestate may only be distributed at certain times on agricultural land in order to protect waterways and groundwater from the addition of too many nutrients. Digestate may not be distributed from 1 November to 31 January.
EEG - German Renewable Energies Act 2009 - act giving priority to renewable energies
In October 2008, the German Bundestag passed a new amendment to the Act to give priority to renewable energies in the electricity sector. The Act has been in force since 01.01.2009. In the interest of climate and environmental protection, its purpose is to enable sustainable development of the energy supply in order to reduce dependence on fossil fuels. At the same time, the focus is placed on reducing dependency on and conservation of fossil fuels, as well as continued development of technologies to generate electricity from regenerative sources.
As part of the amendment, the CHP bonus was increased to €0.03 per kilowatt hour. (Article 27 section 4 no. 3).
Emergency cooling
This step is immediately necessary if an overheated system has to be cooled down to a normal temperature. In biogas plants, the emergency cooler takes away the waste heat from the CHP that cannot be used (usually without recycling it) and into the environment.
Fermentation residue (digestate)
Liquid or solid residue that occurs when biomass ferments in a biogas plant.
Digestate containers
Containers to store the digestate until it is distributed. New biogas plants are required to cover the digestate container, so that no gases escape in order to avoid emission of methane, a significant greenhouse gas.
Humus
A mass of microbially degraded organic substances. Humus helps retain the water in the soil and serves as a source of nutrients for the majority of soil organisms. As a result, it is essential for the soil's biological activity.
Magnesium (Mg)
A chemical element that is vital for all organisms because of its involvement in metabolic processes. As organisms cannot produce it themselves, it has to be added in order to cover daily requirements. In plants, magnesium is the key atom in the green part of leaves.
Phosphor (P)
Chemical element that is vital for creating builders and all organisms functioning. Phosphor is also involved in developing the DNA and supplying energy to the cells. As phosphor in fertilisers cannot be replaced by any other substance, the majority of the phosphor produced is used to make fertilisers.
Process control system
The purpose is to adjust and control all process engineering systems in a plant.
Public interest groups
These are responsible for public concerns and that by German law have to be heard and included when certain construction projects are planned. These encompass various authorities and associations in a particular area.
Remote monitoring
Certain system parameters can be viewed and checked using electronic transmission. This means that discrepancies in a system can be identified early on and amended if necessary.
Renewable energies
All naturally occurring energy sources are considered renewable energies. The most important are: wind, sun, water, biomass and geothermal energy (heat stored in the Earth's crust).
Renewable energy plants
Plants that obtain energy on the bases of renewable raw materials fermenting.
Strip foundations
In construction terms, these foundations are a basis on which a lightweight or sensitive structure can be affixed to a solid bearer. Strip foundations are a simple and commonly used way of transferring the load to the soil.
Substrate
Organic substances added to biogas plants to gain energy via fermentation.
Substrate recovery
All processes of energy recovery in a biogas plant. This is the basic term for the conversion of organic substances by bacteria in the absence of air or light to recover biogas.
Sulphur (S)
Sulphur is a chemical element in the oxygen group that also occurs in amino acids and proteins, secondary plant substances and the green in leaves. Sulphur plays an important role in oxygen-free energy exploitation of many microorganisms and is therefore vital for living creatures. Since the legally required steps to desulphurise flue gases are making themselves felt ecologically, sulphur fertilisation is becoming important in agriculture in order to secure yields and the quality of proteins.
