Why Antec?

Most biogas is generated using a technology that is 40 years old. At Antec we knew there had to be a better way – A Natural Leap Forward! Everyone agrees: Europe and the World needs more biogas plants to become greener and more energy independent. Antec has ‘re-invented’ the Anaerobic Digestion. It’s all about speed: the pace of plant construction and efficiency of the biogas generation. With Antec you build the plants faster, much more efficient with regards to energy consumption and production, using our “plug and play” reactors.
01
Minimal Retention Time
Antec’s technology is much faster than traditional CSTR reactors. The average retention time is reduced from 30 days to 8 days.
02
Higher Gas Yield
Average of 85% gas yield compared to traditional 60% gas yield within the same time frame.
03
Lower Energy Consumption
Reduced energy needs for mixing and substrate heating. Further improvements by installing reactors inside the buildings.
04
Scalability
The technology is easy to scale due to its modular design, off-site manufacturing and minimized footprint.

Industrially Replicating The Market Leader In Digestion: The Cow.

Antec’s pioneering biogas technology mimicks the cow’s digestive system. We combine plug-flow anaerobic digestion with high surface area biofilm to provide an ideal environment for bacteria to thrive. The use of biodigestion chambers allows for greater control of the process and higher gas yields.

Industrially Replicating The Market Leader In Digestion: The Cow.​
We’re industrializing and scaling up our production. Next to selling our technology, we also build whole biogas and biofertilizer production facilities. By pushing our production up and keeping our costs down, we aim to build thousands of efficient, distributed biogas plants where the waste is.

Aquaculture

Fish ensilage & sludge

The aquaculture industry is experiencing intense regulatory and social pressure to reduce emissions to sea, and the environment.
In the foreseeable future it is expected that also offshore production facilities need to collect their biowaste (fish sludge) in addition to the ensilage already collected today, resulting in a significant increase of biowaste that needs treatment.
Mean while, Fish sludge and ensilage while containing significant amounts of energy, also represent challenges when used as feedstock in biogas production
The Antec BioConverters and digestion system is specifically developed to handle the nitrogen inheri t in biowaste from the aquaculture industry. Due to the improved bacterial environment, the system is capable of digesting larger relative volumes of fish waste, creating a sought after path for the treatment of fish sludge and fish ensilage.

Food Industry

Organic food waste

Using food waste as biomass in biogas production is an effective and sustainable way to manage organic waste while generating renewable energy. Organic and clean food waste has high content of energy, and with combination with other types of biomass it is good input for biogas production.
Food waste can be collected from various sources, including food processing industries , restaurants, supermarkets and households. It includes organic materials such as kitchen scraps, vegetable peels, spoiled food, and leftovers. Before entering the biogas digester, food waste has to undergo pre – treatment processes to enhance the efficiency of anaerobic digestion. This can involve shredding or grinding to increase the surface area for microbial activity. It is important to take out plastic, aluminum, glass and other impurities.
Antec is interested in getting in contact with companies which have access to food waste either pretreated or not.

Wastewater Treatment Plants

Waste Water Sludge

Residues from the wastewater treatment plants (WWTP) are mainly considered a liability, due to large volumes of the sludge remaining after the treatment processes. The sludge is typically dried and transported away.
Antec looks at the WWTP sludge as an important resource. By using Antec BioConverters, utilities can gain several benefits:
  • dramatically reduce the volumes of sludge for
    disposal and transportation
  • harvest energy from the remaining organics inthe wastewater-
  • use biogas for internal purposes at the utilities(heating)-
  • produce energy and fuel for the localcommunities-
  • capture nutrients from the rich digestate andproduce fertilizers-
  • achieve shortest retention time in the ADprocess (5-7 days compared to 20 days in theCSTRs)

Animal Farmers

Animal Manure

At the core of Antec ’ s operations is our relationship with surrounding farmers. A symbiotic exchange between the biogas plant and the farmers turns cow manure into a valuable resource.
Farmers deliver their cow manure to the biogas facility, and in return, receive nutrient – rich biofertilizer — outperforming traditional manure and reducing the need for artificial fertilizers. This not only enhances crop yields but also cultivates healthier, more r esilient soils.
Beyond the agricultural benefits, we take care of the logistics. Farmers no longer incur costs transporting manure to external storage facilities; the biogas plant handles that. This not only streamlines operations but also contributes to substantial cost savings.
Environmental stewardship is at the core of our offering. By extracting almost all methane from the manure, we significantly reduce the environmental footprint of farming practices. Together, we’re forging a sustainable future where agriculture and ecology harmonize for the prosperity of both farmers and the planet
