We offer the option of developing the project under a turnkey contract, if that the client wants to do is completely outsource the execution of the biogas plant. In that case, we support the client at every stage of the project of their biogas plant with a comprehensive service, including the previous services and the design and construction of the installation.
Our work methodology and customer relationship
We add value at each phase of the project. We are a trusted partner for long-term follow-up.
Our biogas experts assess and develop turnkey projects, taking into account the limitations or constraints of each installation and the site from an operational point of view.
Whether it be an existing installation or a new build project, at Norvento we work closely with each client in all project phases, from the technical-economic feasibility study, through design and engineering, construction, to plant commissioning. operation and maintenance.
In the early phases of the project, we advise the client on whether or not to consider a biogas plant in its installations, making a characterisation of the effluents and by-products that may be generated in them and evaluating the best solutions. Considering all the possible synergies derived from the consumption of resources, energy and waste management, we make an economic-financial assessment for the client. We advise the client regarding the financing of the project.
Once the decision has been made, we offer the client a comprehensive engineering service to carry out the construction project in question and we support them in the requisite official approval processes. The scope of these services is defined with the client, taking into account their needs and the extent of the client’s resources that can be made available to Norvento. The comprehensive service also includes the optimal solution to valorise biogas and digestate, the main products of anaerobic digestion.
At the customer’s convenience, we are involved throughout the useful life of the project, through a series of operation and maintenance services, ensuring a fully functional plant that stays within the expected production margins.
What is biogas?
Biogas is a sustainable fuel composed mainly of methane (CH4) and carbon dioxide.
It can be produced in natural environments or in specific devices, due to biodegrading or decomposition reactions of residual organic matter in the absence of oxygen, through the action of micro-organisms and other factors (temperature, agitation, etc.).
Biogas is a renewable energy source, which fulfils a dual objective: reducing greenhouse gas emissions into the atmosphere and saving in the management or treatment of organic waste.
Biogas is produced by a process known as anaerobic digestion, consisting of the fermentation of organic matter in the absence of oxygen. The organic waste used as the raw material of the biogas plant can come from a wide variety of sources:
- Agriculture and Livestock
- Agri-food Industry Dairy, Slaughterhouses, Canning
- Food Processing, Beverage Production
- Other sectors: Paper mills, HORECA
- Municipal waste and purification plants.
Raw biogas is composed mainly of:
- Methane (CH4): 50-75%
- Carbon Dioxide (CO2) 25-50%
- Other substances in minor amounts (siloxanes, H2S, H2O).
To make biogas fit for purpose, the unwanted compounds must be eliminated. The degree of cleaning of biogas will depend on its final application.
The main applications of biogas are:
- Direct thermal use. Combustion of biogas in thermal generation equipment (boilers, dryers or ovens) for self-use.
- Use in co-generation. Biogas combustion in cogeneration engines to generate electrical and thermal energy.
- Bio-methane production. Elimination or conversion of carbon dioxide (CO2) present in biogas through a process known as upgrading to obtain a gas with a very high methane content (> 90%), and properties similar to those of natural gas.
- Feeding biomethane into the natural gas grid.
Norvento Enerxía, the best ally for developing biogas plants
Take advantage of organic waste from your industrial or agricultural processes and convert it into electricity and heat.
If you operate an industrial plant with a high load of organic waste and you need electricity and heat, you can valorise your waste with our biogas plants for self-use, which encompass all the processes necessary for the synthesis of fuel and its subsequent use.
Safe for the public, they will enable you to reduce your carbon footprint, improve your bottom line, and protect yourself against fluctuations in fossil fuel and electricity prices.
Our plants are modular and you can adapt them to your particular needs as well as to the infrastructure already available in your installations.
Our R&D projects in the field of biogas.
Norvento is a world leader in research and development in biogas projects. Some of the collaborative projects we are currently working on are:
Programme: Fast Track to Innovation.
Reference number: 950921
With the NEOSUCCESS RDI project we set out to implement a unique solution based on a containerised “plug and-play” technology designed to be integrated into the operational line of work of biogas plants.
This new technology will make the investment in biogas improvement technology more profitable thanks to its complementary exploitation of bio succinic acid (BioSA).
NEOSUCCESS is the first technology in the world that recycles and uses waste to simultaneously produce two products with high added value:
- BioMetane (> 95%) from biogas to be used as bio fuel.
- BioSA (> 80%), a second generation non-fossil alternative to succinic acid (SA). This new product is a revolutionary biogas that binds CO2 to a valuable biochemical element.
It can thus cut your production costs and reduce your environmental footprint.
Another of the research projects in which the Norvento Biogas Unit participates is the VARAL Project in which Norvento, together with other Galician companies, has developed a comprehensive recovery plant for by-products and residual effluents from the dairy sector.
This project, within the framework of the Conectapeme 2018 programme, is financed by the Government of the Autonomous Community of Galicia (Spain) through the Galician Innovation Agency (GAIN) and the support of the Department of Economy, Entrepreneurship and Industry and is co-financed by ERDF Funds in the framework of axis 1 of the ERDF Galicia 2014-2020 operational programme.
