Calpech is a spin-off from the University of Alicante that manufactures carbon-encapsulated iron nanoparticles, an innovative technology patented at European level. This technology also enables the manufacture of liquid additives that increase biogas yield and eliminate H₂S from digesters.
Calpech is also focused on circular economy and waste valorization providing technical assessment on these areas.
What are the main areas of activity of the company?
Calpech manufactures carbon-encapsulated iron nanoparticles for various environmental applications. In addition, based on this technology, Calpech markets a product in liquid additive format that increases biogas and eliminates H₂S from digesters, among other benefits.
Calpech also offers laboratory services such as measuring biomethanisation potential and controlling and optimising digester diets.
What’s the news about new products/services?
Calpech offers a range of Ce-In products with additives designed for the biogas sector.
The most notable is Ce-in Desulf. This additive’s main function is to eliminate 95% of hydrogen sulphide (H₂S). It also has a neutral, non-corrosive pH, does not contain chlorine, and is easy to dose.
What are the ranges of products/services?
Calpech offers a range of Ce-in products, additives designed for the biogas sector.
Ce-in Biogas
The main function of this additive is to increase the volume of CH4 by 40%. It also provides macro and micro nutrients, does not degrade over time, comes in an easy-to-dose liquid format, and improves the quality of the digestate.
Ce-in Desulf
This additive’s main function is to eliminate 95% of hydrogen sulphide (H₂S).
It also has a neutral, non-corrosive pH, does not contain chlorine, and is easy to dose.
Ce-in Max
Comprehensive solution that combines the advantages of the two previous products, eliminating 95% of hydrogen sulphide, increasing biogas production by 40% and providing micro and macro nutrients.
On the other hand, Calpech offers a range of services for:
- Biomethanisation Potential Measurement (BMP)
- Digester Diet Control and Optimisation
- Waste, Digestate and Biogas Characterisation
What is the state of the market where you are currently active?
We are currently active in Spanish biogas market where we are serving several customers. In addition to this, the first exportation to other countries in the world such as Brazil or Argentina has already begun. Commercialization in Europe is beginning where the first contacts with potential customers have already taken place.
What can you tell us about market trends?
Spanish biogas market that is the market with foreseeable higher growth in the world due to its potential of agricultural waste valorization and growing renewable energy demand.
What are the most innovative products/services marketed?
Both Ce-in Biogas and Ce-in Desulf are additives based on iron nanoparticles. Until now iron nanoparticles were not used in biogas market due to their production cost. The new patented production process enables their use for applications such as biogas production. It is the first time that nanotechnology is employed in this sector commercially.
What estimations do you have for the end of 2025?
The estimation is that at the end of 2025 the start-up company would have sold more than 200 tons of biogas additives based on iron nanoparticles. Moreover, the first sales in other European markets are expected to begin at the end of 2025.
