The utilization of an anaerobic digester to process palm oil mill effluent biogas, animal manure biogas, and food waste biogas has now become a strategic financial instrument. Through the methane capture mechanism, companies can generate high-value carbon credits in both the Voluntary Carbon Market and domestic markets. This investment does not only support Indonesia’s Nationally Determined Contribution (NDC) but also transforms measured industrial emissions reduction into a new flow of cash beyond the mill’s primary revenue.

Why Does Methane Capture from Organic Waste Have High Carbon Value?
In the sustainable agriculture ecosystem, liquid and solid wastes that were once an environmental cost burden can now be transformed into financial assets through the right biodigester technology. The effectiveness of methane capture across various sectors—ranging from Palm Oil Mill Effluent (POME) Biogas, Agriculture & Animal Manure Biogas, to Food Industry Biogas—is the fastest method to obtain carbon certification.
Investing in this technology is more than just fulfilling Nationally Determined Contribution (NDC) regulations; it is a strategic move to strengthen corporate sustainability practices. By converting methane into energy or Bio-CNG, companies secure an independent energy supply chain while simultaneously gaining a new revenue stream from the carbon exchange.
Methane vs. Biogas: Which Gas Generates Carbon Credits?
In an anaerobic digester system, the generated biogas typically consists of 50% – 70% Methane (CH4), 30% – 50% Carbon Dioxide (CO2), and residual gases (H2S, nitrogen).
Why is CO2 in Biogas Not Counted?
In carbon methodologies (such as CDM or Verra), the CO2 naturally contained in biogas is considered Biogenic CO2.
This gas originates from plants (like oil palm in the case of palm oil mill effluent biogas) that absorbed CO2 from the atmosphere during their growth.
Because the cycle is considered neutral (absorbed and then released back), the natural release of CO2 from biogas is not regarded as a contribution to global warming; therefore, it cannot be claimed as carbon credits.

Why is Methane (CH4) Counted?
Methane in liquid waste or agriculture waste biogas forms due to anaerobic (oxygen-free) conditions in waste lagoons. If not captured by a biodigester, this methane escapes into the atmosphere.
Because methane’s global warming potential is 28 times stronger than CO2, governments and carbon agencies provide “credits” for every molecule of methane you prevent from being released or that you combust (flaring/engine) back into CO2.
Biogas Downstreaming: Biogas Upgrading, Bio-CNG, and Biomethane
For companies looking to maximize profit, strategic steps no longer stop at mere biogas production from waste. The process of biogas upgrading into biomethane, compressed biomethane (Bio-CNG), and Bio-LNG has become the new standard for significantly strengthening a company’s Carbon Dioxide Removal (CDR) profile.
Utilizing Bio-CNG or Bio-LNG as a fossil fuel replacement—whether for logistics fleets, industrial boilers, or power generators—provides a substantial impact on CO2 reduction. This is recognized by both Verra and Gold Standard (See Verra Methodology VMR0006 & Gold Standard Renewable Energy Guidelines).
Understanding the Market: Voluntary Carbon Market and SRN-PPI
For project owners in Indonesia, registration through the Nationally Determined Contribution (NDC) via the SRN-PPI track is a mandatory step. However, opportunities in the Voluntary Carbon Market (such as Verra or Gold Standard) remain open for companies targeting international buyers with premium carbon credits pricing.
How to Register Your Project to the Carbon Exchange?
As a mill owner or industrial decision-maker, the steps you take depend on the current status of your renewable energy assets:
If You Do Not Have a Biogas Plant Yet
This is a strategic position as you can design the system from the ground up (Greenfield) to meet Nationally Determined Contribution (NDC) standards.
- Baseline Audit: Calculate the methane emissions currently escaping from your open lagoons.
- Technology Selection: Use an anaerobic digester with high methane capture efficiency. Technologies like biogas upgrading to biomethane or Bio-CNG will enhance the project’s value for carbon verifiers.
- Documentation: Ensure all technical design data is documented for Voluntary Carbon Market registration, which will be fully supported by the Organics Bali team.
If You Already Have a Biogas Plant
If the installation is already operational, your primary focus is proving additionality and ensuring accurate data monitoring.
- Retrofitting & Upgrading: Consider adding biogas upgrading units or CO2 recovery to strengthen Carbon sequestration or Carbon Dioxide Removal (CDR) aspects.
- Official Registration: Immediately register your project through the SRN-PPI scheme to obtain SPE-GRK.
Official Guidance: You can study the detailed technical registration flow and methodologies via the government’s official portal at the Sistem Registri Nasional (SRN) PPI.
Case Study & Financial Simulation: Biogas Co-firing Project from a 75 TPH FFB Palm Oil Mill
For a real-world perspective, we can reference a project constructed by Organics Group in November 2025 in Central Kalimantan for PT BGA. This project serves as proof that proper technology integration is the primary key to eligibility and high carbon economic value.
Project Profile
- Co-firing Utilization: Biogas generated from POME is used to replace fossil fuels in boiler engines, contributing directly to industrial emissions reduction.
- Enclosed Flare Eligibility: A key component in the BGA project is the use of an enclosed flare. Unlike open flares, enclosed flare systems are highly preferred by carbon auditors because they guarantee methane destruction efficiency of >99% and allow for continuous combustion temperature monitoring. This makes the project much more likely to pass carbon credits verification.
Carbon Credit Calculation Simulation (Estimated)
Assuming a 75 TPH (Tons Per Hour) capacity mill generates a stable flow of treated POME, here is a rough estimate of its emission reduction potential:
- Methane Avoidance: Diverting methane gas from an open lagoon to a covered lagoon anaerobic digester system yields an average reduction of 20,000 tons CO2e per year.
- Energy Substitution (Co-firing): Reducing the use of fossil fuels (such as coal or diesel) provides an additional reduction of approximately 2,000 tons CO2e per year.
- Total Carbon Credits: 22,000 Carbon Units (SPE-GRK) per year.
Potential Additional Revenue (Revenue Stream)
Assuming carbon credits prices on the carbon exchange (IDXCarbon) or Voluntary Carbon Market reflect 2026 market trends:
Estimated Revenue: 22,000 units x USD 5 – 10 (moderate price assumption) = USD 110,000 – USD 220,000 per year.
Note: This revenue is net additional revenue, gained in addition to the operational cost savings (OPEX) from reduced fossil fuel purchases.
Vital Variables Every Mill Owner Should Know
Before deciding on an investment, ensure you have calculated the following variables:
- Carbon Selling Price: Determine whether to sell through domestic schemes (SRN-PPI) or international markets (Verra/Gold Standard).
- Carbon Formula:
Total Credits = (Biogas Volume x % Methane) x GWP Factor (28)
- Monitoring & Verification Cost (MRV): Budget for the annual fees of Independent Validation and Verification Agencies (LVV).
- Upgrading Efficiency: If you plan on biogas upgrading to biomethane or Bio-CNG, the profit calculation will differ due to the added value of selling Green Fuel.
How to Calculate Your Project’s Feasibility?
Every mill has unique waste characteristics. Your FFB capacity per hour and current waste management system will heavily dictate the CAPEX investment and potential carbon profits.
