Turning Waste into Wealth with ActiCH4R™
Boost your biogas plant’s methane yield, efficiency, and profitability with our breakthrough catalyst.
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.
How it works
The Science Made Simple
ActiCH4R™ makes biogas production smarter and faster. Simply add our natural catalyst, accelerate microbial activity, and maximise methane output — all while improving plant stability.

ActiCH4R™ FAQs
What is ActiCH4R™?
How does ActiCH4R™ work?
ActiCH4R™ accelerates methanogenesis — the final step of biogas production. It provides surfaces for microbial biofilms, adsorbs inhibitors such as ammonia and acids, and balances digester chemistry. This means volatile fatty acids (VFAs) are consumed faster, pH stays stable, and methanogens operate at a higher rate. Plants can handle higher loading without the risk of acidification or foaming.
What benefits can I expect in my plant?
ActiCH4R™ consistently delivers:
- 25–40% higher biogas yield
- Greater plant stability (fewer pH swings, less foaming)
- Higher CH₄ concentration, lower H₂S
- Stronger microbial populations
- Improved fertiliser quality from the digestate
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?
ActiCH4R™ is mixed directly into your daily feed. No retrofit, new equipment, or process redesign is required. Dosing is straightforward and can be adjusted depending on your plant’s needs. RAFT Energy will work with you to provide accurate dosing support, ensuring the product is tailored to your specific feedstocks, loading rates, and plant conditions.
What happens if feedstocks vary or conditions change?
ActiCH4R™ has shown strong resilience under challenging conditions, such as variable feed quality or lower operating temperatures. By buffering chemistry and strengthening microbial communities, it helps maintain stable digestion and consistent gas production even when inputs fluctuate.
How does ActiCH4R™ improve plant stability?
Why should I invest in ActiCH4R™?
Because it turns your existing plant into a higher-yield, more profitable, and more stable operation — without adding new digesters or major capex. More methane per tonne of feedstock means higher revenue, smoother compliance, and better sustainability performance.
