OPS are carbon-encapsulated iron nanoparticles that improve the efficiency of the anaerobic digestion process, optimizing microbial metabolic pathways to increase biogas production and reduce the formation and degradation of unwanted compounds.
OPS can be dosed directly into the digester feed, ensuring even distribution throughout the system. The exact application method can be adjusted according to the plant’s design and feed type.
No, OPS can be applied without modifying the plant’s infrastructure. Its use is compatible with standard anaerobic digestion processes.
No, OPS has no negative effects on digestate. In fact, the presence of iron nanoparticles could even improve some properties of the final fertilizer by providing bioavailable iron.
The recommended dosage is 2-3 kg of OPS per ton of volatile solids (VS). To calculate the exact amount, it is necessary to know the average VS content of the raw materials used in the plant.
You can use our simulator to make an initial rough calculation.
The effects are usually visible between 2 and 4 weeks after application, depending on the water retention time of the plant.
Yes, it is recommended to analyze the volatile solids (VS) content or the average annual VS tonnage of the raw materials used. This allows for calculating the optimal amount of OPS for the plant.
Yes, by optimizing microbial activity, OPSs help stabilize methane production and reduce fluctuations in its concentration.
OPS can reduce the need for certain additives, especially those used for H₂S control. However, complete replacement will depend on the specific conditions of each plant. OPS are compatible with most additives commonly used in biogas plants.
Yes, OPS has been validated with different types of organic waste, such as manure, agro-industrial waste, and sewage sludge.
No. Tests have shown no adverse effects on anaerobic digestion or process stability. Furthermore, the product’s non-toxicity has been certified through independent studies.
OPS has been implemented in several biogas plants in Europe. While not yet present in all countries, Smallops is expanding and seeking new strategic partners for its commercialization.
