Biological Performance Optimisation for Anaerobic Digestion
ActiCH4R™ is a natural, activated catalyst that improves microbial performance inside anaerobic digesters — delivering higher methane yields, more stable operation, and greater resilience to feedstock variability.
- Increase methane yield by accelerating microbial conversion of organics
- Improve digester stability by strengthening biological resilience
- Process more feedstock without triggering instability
- Validated in live plant trials
- Proven across multiple commercial AD facilities
ActiCH4R™ enhances the biological efficiency of anaerobic digesters.
By supporting microbial activity and improving reaction conditions inside the digester, ActiCH4R™ helps plants unlock higher methane yields, smoother operation, and greater resilience to feedstock variability.
What is ActiCH4R™?
ActiCH4R™ is a natural, activated catalyst developed to accelerate the anaerobic digestion process. By supporting the biology and chemistry inside your digester, it enables faster, more efficient conversion of waste into methane.

ActiCH4R™ FAQs
What is ActiCH4R™?
ActiCH4R™ is a natural, carbon-based catalyst designed for anaerobic digestion. It strengthens the biology and buffers chemistry inside your digester, helping microbes convert feedstock into methane more efficiently. The result is higher yields, greater stability, and smoother day-to-day operation — without the need for new tanks or costly retrofits.
How does ActiCH4R™ work?
What benefits can I expect in my plant?
ActiCH4R™ consistently delivers:
- 25–40% higher biogas yield
- Greater plant stability (fewer pH swings, less foaming, reduced NH3)
- Higher CH₄ concentration, lower H₂S
- Stronger microbial populations
- Improved fertiliser quality from the digestate with stabilised NKP reduced runoff
Which types of feedstocks does it work with?
ActiCH4R™ works across a wide range of substrates, including:
- Food waste (municipal, supermarkets, catering)
- Manure and agricultural residues
- Abattoir and rendering waste
- Municipal wastewater sludges
- Mixed co-digestion setups
Is it safe for microbes and digestate use?
Yes. ActiCH4R™ supports microbial activity rather than suppressing it. The resulting digestate retains more nutrients and nitrogen, making it a higher-quality fertiliser. It is safe, non-toxic, and easy to handle.
Will it work in my type of digester?
Yes. ActiCH4R™ is compatible with all common AD systems, including:
- Continuous stirred-tank reactors (CSTR)
- Plug-flow digesters
- Covered lagoons
Both mesophilic and thermophilic processes
How is it applied?
What happens if feedstocks vary or conditions change?
How does ActiCH4R™ improve plant stability?
ActiCH4R™ reduces the buildup of VFAs, balancing FOS/TAC ratios, and lowers free ammonia levels. This prevents common process upsets like foaming, acidification, or sudden drops in gas output. In practice, plants run more predictably with fewer interventions.
