Biogas and Biomethane: clean energy that sustains the planet
A precious renewable energy source from waste
Agricultural plants
- The evolution towards the circular economy is now an unstoppable process and it takes place through the recycling of by-products and waste generated by our cities, industries and agriculture, to become a precious resource for the production of renewable energy.
Agro-industrial plants
- A great opportunity to revisit and enhance the processes aimed at better resource efficiency, focusing on a more sustainable and environmentally friendly economic activity that generates income and employment.
OFMSW
- Where it is not possible to avoid the production of waste, its economic value must be recovered, minimizing the impact on the environment, in compliance with the European Union strategy and the Paris agreement of 2015, but above all for the environmental benefits in terms of lower CO₂ emissions.
Biogas purification with BTS Biogas technology
Washing process using pressurized water
- With this process, CO₂ and hydrogen sulphide are dissolved in water and separated from biogas.
The biogas is subjected to pressure and purified inside a column filled with countercurrent water. The "unwanted" gases are absorbed by the water while the purified gas, after passing through the column, is drained, dried and made available for entry into the network or for direct use.
At various points in the system, heat is extracted which can be used for heating the tanks of biogas plants.
Process using membranes
- In the process that uses membranes, the biogas with pressurized water is first purified of hydrogen sulphide and brought to a higher pressure using compressors.
Methane is then separated from the CO₂ using membranes. It is thus possible to extract all of the methane from the raw biogas, with a dispersion of less than 0.1%.
The part containing CO₂ is further compacted in the separation with membranes and then condensed to obtain 100% pure CO₂, which can be used above all in the food industry.
While washing with pressurized water provides greater benefits if performed in large plants (> 2 MW), it is preferable to carry out the treatment using membranes in small and medium-sized plants.
PSA technology, oscillating pressure adsorption
- The separation of CO₂ from methane takes place inside columns containing adsorbent material.
The pressure varies in the columns so that by increasing this value, the CO₂ is absorbed by the material. The system consists of several parallel columns.
When the absorbent properties of one column become saturated, the raw biogas is conveyed to the next column.
Chemical washing
- In this case, the raw biogas and a CO₂ absorption liquid are conveyed into a countercurrent absorption column.
The outgoing gas acquires a purity similar to that of natural gas. While the CO₂ impregnated absorption liquid is used for stripping for the separation of the latter.
After suitable cooling, pure CO₂ with a high commercial value is obtained.
Our DNA is green - Circular economy: recovering to create value
WHAT IS THE CIRCULAR ECONOMY?
The circular economy is a model based on the idea of an economy that is capable of regenerating itself.
The term circular is used precisely to indicate the contrast with the common (linear) economic model based on: production, use and waste.- Return biological materials to the environment
- Give new life to technological components, preventing them from affecting the environment
In fact, in the case of the circular economy the key concept is the recovery and reuse of existing materials and products.
Once it reaches the end of its life cycle, a product can be broken down into its parts and reintroduced into the economic cycle, thereby reusing it in the production cycle and generating value.Unlike the linear economic model which provides for enormous quantities of energy and raw materials to be used in the production phase and which does not focus on the problem of waste, the circular economy starts from waste, to reduce the quantities and lengthen the life-cycle of products.
The circular economy results in:- A favorable impact on the climate. Reduction of energy consumption and CO₂ emissions
- More rational use and processing of raw materials, to reduce environmental exploitation
- Increased competitiveness and a drive towards innovation
- Economic and employment growth
Biogas: recovering to create energy
- Biogas is able, with a single process, to recover scrap and waste, to give it a new location and make it useful again and to create a necessary product such as energy. All without burdening mankind or the environment.
Waste management
- Where it is not possible to avoid the production of waste, its economic value must be recovered, minimizing the impact on the environment, in line with the European Union strategy and the Paris agreement of 2015, but above all for the environmental benefits. in terms of lower CO2 emissions.
Agricultural plants

Organic Waste
- Where it is not possible to avoid the production of waste, its economic value must be recovered, minimizing the impact on the environment, in line with the European Union strategy and the Paris agreement of 2015, but above all for the environmental benefits. in terms of lower CO2 emissions.
Our DNA is green - Renewable energies for a greener world
The potential of Biogas as green energy
Biogas is able, with a single process, to recover scraps and waste, to give a new location and new usefulness and to create a necessary product such as energy. All without burdening man and the environment.
In the general framework of renewable energy, biogas is the most programmable energy, able to balance the contribution of other renewable sources that cannot be planned.
It is the most flexible element, since it can be stored in the form of heat, electricity or biomethane, so that energy can be used when and where it is needed.
It contributes to the important sustainability process represented by valorizing urban waste.
The use of plant biomass in biogas plants to produce energy is one of the most efficient systems for reducing greenhouse gas emissions, in implementation of the 1998 Kyoto agreements and in compliance with the European Union decarbonisation goals by 2030.
Among the renewable energies, Biogas is the greenest, not only because it manages to reconcile the disposal of waste material with the production of clean energy, but also because it requires less energy for the plant’s production and life-cycle.Biology and Assistance: Biology and innovation at the service of Biogas
-
In a constantly growing and changing market such as that of renewable energy and anaerobic digestion, in BTS Biogas we established the first private laboratory in Italy dedicated exclusively to biogas years’ ago.
In the present day, our work continues in this direction. Our goal is to constantly work on improving products and services.
In all the activities we carry out, attention is paid to: use of cutting-edge technologies and standards, safeguarding of environmental protection requirements, ensuring safe and profitable operation, obtaining an optimal production process. MetanLab
- Using a state-of-the-art laboratory, we work on the development of a new generation of plants, to ensure even more lasting, safe and profitable operation.
dinaMETAN
- Following scientific methods, we collect empirical data that describes the production processes and the yields of biogas in different conditions.
Thanks to this data, it is possible to constantly improve the design and management of biogas plants, by inserting the data in the dinaMETAN database.
TECHNOLOGIES
- Our technical and biological know-how, together with vast experience in the operation of biogas plants have led to the development of countless solutions and products that have become part of plant standards.
These are systems for the production, operation and control of plants, pre and post treatment of substrates and technologies for the production of biomethane. PRE-TREATMENT
The various innovative technologies for pre-treatment allow:
- Maximum possible increase in biogas yield
- Biomass savings and cheaper operation of biogas plants
- Reduction of the residence time in fermenters and increase of the organic load
- Lower volumes in tanks and reduction of investment costs
- Prevention of the formation of floating layers and deposits in tanks
- Prevention of the penetration of pollutants into fermenters
- Reduction of costs due to the agitation of the material and the self-consumption of the plants
BIOacceleratorsS
- A BIOaccelerators is an extruder that optimizes the decomposition of the inlet substrates through defibration, to achieve a greater biogas yield.
In this way, new substrates can be added more quickly to the fermentation process.
Thanks to the thermo-mechanical treatment of the substrate, the input material is subjected to an already high temperature, so as to reduce the consumption of electricity.
BIOacceleratorzZ
- A BIOacceleratorz is a biomass shredder that allows the fermentation of non-fermentable or difficult to process substrates without treatment. In this case, the incoming material is separated and mechanically shredded by the hammers and the rotating defibration elements at the bottom of the tank.
BIOseparatorwW
- In the BIOseparatorw, the biomass is cleaned of contaminants and shredded with hammers and a grinder filter and then flows into the storage tank or is directly pumped. Contaminants (glass, metals, plastics, etc.) are expelled from the exit tray. A screw extruder is integrated in the outlet mouth which uses all the liquids still contained in the contaminants and re-supplies the process.
PLUG & PRODUCE
-
This technical module, developed in our BTS Biogas workshop, serves as the technical center for biogas plants.
It is compact and modular, has standard sizes, which can be customized if necessary. It requires less investment than a common building installation. This technology results in savings in terms of production time and therefore assembly costs. The module is manufactured and tested on the company’s premises, thus ensuring greater reliability. It is available in various customizable sizes, for both new and existing plants. The following are positioned inside the module: gas measuring instruments, desulphurization blowers, the system for the distribution of heating and pumps, the air conditioning system, the running water distribution system and also, where required, a heat exchanger that is placed on the roof.
Service Box
- With the BTS Biogas serviceBOX, maintenance and repairs can be carried out quickly and efficiently starting from the fermenter agitator.
The serviceBOX & servicePLATFORM combination ensures:- Working in total safety during maintenance work on the fermenter
- No biogas loss thanks to the stainless steel "miniskirt" inside the tank
- No emptying of the tank or stoppage of biogas production during maintenance
- Adjustment of the height and orientation of the agitators for precise agitation that prevents the formation of crusts
- Lighted porthole for biomass control inside fermenters
- Surveillance camera with cleaning nozzles for internal control of fermenters
DIGITALIZATION
METANload
- The METANload system is a software developed by BTS Biogas, for visualization and control of the filling of the hopper.
It is an intelligent calculation application, with integrated hardware components, which helps the operator to optimally supply the biogas plant.
Plant managers receive precise information in real time on what has already entered the plant and on which substrate components must be added to obtain optimal proportions of the mixture.
dinaMETAN
- DinaMetan allows the calculation of the optimal biological yield, maximum energy production, the degradation rate of the substrates, the need for bacteria during the fermentation process, ideal spatial exposure, optimal retention time in fermenters and the most beneficial costs of the substrates for each kWh produced.
INFOmodule
- Thanks to INFOmodule, a system developed internally by BTS Biogas, the personnel in charge of a plant’s operation can remotely check and intervene on it at any time.
In the event of anomalies, the system sends voice alerts by telephone, classified according to defined priorities.
POST-TREATMENT
- Well thought-out post-treatment means our customers can reuse residual digestate in a variety of ways.
BIODry
- Drying is the most efficient method to use the excess heat of the biogas plant and to transform the slurry into a precious fertilizer.
A solid and a liquid product are obtained from this process: dried digestate (BIOdry) and ammonium sulphate.
Drying allows the optimization of the biogas plant by adding an additional source of income.
Soil quality is improved because of the high organic content of the fertilizer, and its components have a lasting effect.
NITROStripp
- Stripping is a method that solves the nitrogen problem. It is mainly used in biogas plants supplied with a lot of slurry.
The stripping process can also be carried out without using chemical additives.
BIOPellet
- The resulting material of the anaerobic digestion process can be pelleted with considerable benefits in economic, managerial and agronomic terms.
The material, previously dried with BIOdry, is filtered, pressed, sifted and added. The pellets are then packaged in Big-Bags or 15/25kg bags.
This technology alternatively allows the production of digestate pellets and BIOfire wood pellets, giving flexibility and investment profitability benefits.
Repowering
- We are not only dedicated to the design of plants from scratch, but we also carry out interventions on plants that have already been built.
By combining our different technologies with the experience gained in the field, we modify the power supply and related processes connected to plants to achieve maximum technical, biological and economic efficiency.
