Welcome to this preliminary version of the calculation program for biogas production.

The program is under development and will be continuously updated.

In this preliminary version, it is necessary that you know about the biomasses that are available for biogas production so that an expected biogas production can be calculated.

Additional facilities will be added to the program subsequently.

You are welcome to fill in information about the company and yourself, but it is not necessary for the actual calculation in this preliminary version.

Farm description

Number of farms for the holding		Number
Distance between farms		km
The total area of the farms		Hectares

Type and number of animals

Animaltype

Number of animals

Area for spreading the digestate		Hectares
Water consumption		m³/year
Volume of facilities to store manure		m³
Electrical power consumption on farm		kWh/year
Heat consumption on farm		kWh/year
Distance to existing biogasplant		km
Distance to gas network		km

In this section, we would like to have basic information about your farm so that we can form an impression of it.

A holding can consist of several farms. If the holding consists of more than one farm, we would like to know how big these are and how far apart they are. This may have implications for later calculations of costs for transport and logistics.

Under "Type and number of animals", several different ones can be selected. These will be used in a later version to estimate the quantities of livestock manure that these give rise to, depending on which country you are in.

Information about the area, water consumption, electricity and heat consumption will later be used to assess whether it is appropriate to establish biogas production for the farm.

If there are existing biogas plants nearby or the possibility of connecting to another outlet for the biogas, this is important to know.

Biomass

In this section, it is specified which biomasses are available for biogas production.

It is important to choose these biomasses, as it is these choices which (in this version of the program) are the calculation basis for the biogas production. It is possible to choose between four different categories of biomass. When you have chosen the categori, options appear in the box with biomass types.

When you have chosen a biomass type, some default values for the dry matter content and for the organic part of the dry matter appear in the boxes below. If you have more precise information for the biomass in question, you can enter these instead of the default values.

You have to select all the biomasses that are available and add them one at a time.

The program adds all the biomasses together and calculates the expected gas production based on these.

Results

Biomass treated total		tons
Methane production		Nm³/year
Methane content in gas		%
Biogas production		Nm³/year
Biogasprod. pr. ton biomass		Nm³/tons
Plant size power		kW
Plant size heat		kW
Investment (1000)		€
Total cost pr. year		€
Total income pr. year		€

Under results, you can see a tally of the mass of the entered biomasses, the expected biogas production and the methane content in the gas.

Recommendations

Under recommendations, an initial recommendation is given which depends on calculations of the expected biogas production based on the biomasses entered.

Preliminary evaluation of a biogas plant tool

The purpose of this document is to provide users with information about the possibility of giving value to manure and agricultural by-products of one or more companies through the production of biogas or biomethane.

Biogas plants are complex systems, and a complete evaluation of their feasibility would therefore require the analysis of a large number of parameters and cannot be done without the inspection of a specialized technician. In the same way, a complete and reliable economic evaluation would require very detailed information on the organization responsible for the plant realization (for example, a farm). The information obtained summarize the results of an automatic calculation tool and cannot be considered a feasibility study nor a commercial offer.

If the user considers positive this results and wants to deepen the results can contact the technical staff of ALFA-project.

The version currently available is to be considered in the testing phase. The authors of the tool thank those who wish to write to ALFA-project to report any mistakes and suggest improvements.

The authors of the tool accept the responsibility for the contents of this tool to the extent indicated above. The authors cannot be held responsible for improper use of the results contained by the tool, which are purely indicative and are subject to change subordinated to modifications and corrections of the tool.
