Step 1
Diversion from Landfill
Organic waste is redirected from simple landfill disposal into anaerobic digestion.
Sustainability
Environmental and Circular Value
Converting high-volume organic waste into renewable energy, CO₂ reduction, and circular fertilizer recovery through the DHM DBES process framework.
Reference values based on a 1,000 t/day model
Resource Circulation
From Waste to Energy and Fertilizer
Outlines how organic waste moves through energy generation and fertilizer recovery into a circular resource system.
Step 2
Methane Capture
Biogas generation captures methane in a managed process rather than leaving emissions unmanaged.
Step 3
Energy Generation
Recovered biogas can be used for electricity and heat generation or upgraded into biomethane.
Step 4
Circular Nutrient Recovery
Digestate is recovered as liquid fertilizer and compost, returning waste-derived nutrients to agriculture.
Key Outputs
Energy, Greenhouse-Gas and Fertilizer Outputs
Based on a 1,000 t/day reference plant with CH₄ 65% as the biogas assumption.
Electricity and CO₂ use a 365-day annual basis, while fertilizer outputs use 330 operating days.
Annual Electricity
40,150 MWh/year
50 ㎥/t × 1,000 t/day × 2.2 kWh/m³ × 365 days
Annual CO₂ Reduction
178,485 tCO₂/year
489 tCO₂/day × 365 days
Liquid Fertilizer Output
231,000 t/year
700 t/day × 330 operating days
Solid Compost Output

Use Cases
Reference Values for Planning, Review, and Disclosure
These reference values can support planning, investment review, and disclosure preparation.
Waste Management and Resource Circulation
Estimate processing capacity and recoverable energy and fertilizer volumes when planning resource circulation strategies.
Investment Review Basis
Use energy output and by-product revenue as a starting point for revenue estimation and feasibility screening.
Greenhouse-Gas Reduction and Disclosure
Leverage quantified reduction figures as supporting evidence for ESG disclosure and carbon-reduction reporting.
Interpreting CO₂ Reduction
What to Check When Reading the 489 tCO2/day Figure
This section explains what the greenhouse-gas reduction figure means in the reference plant and what should be checked before project application.
Interpretation Scope
What This Reduction Figure Represents
This figure is a reference value showing the level of greenhouse-gas reduction expected from the reference plant. Before project application, differences in feedstock mix and operating conditions should be reviewed together.
Pre-Application Checks
- - Methane has a global warming potential (GWP) up to 28 times higher than CO₂.
- - Actual reduction levels can vary with feedstock mix, design, and operating conditions.
- - Project-specific greenhouse-gas accounting should be verified separately.
Scope and Variability
Fixed Assumptions and Site Variables
These notes show which values are fixed as reference assumptions and which can vary by site conditions.
- - These figures are based on a 1,000 t/day reference plant.
- - Electricity and CO₂ values use 365 days/year.
- - Fertilizer outputs use 330 operating days/year.
- - Actual values can vary with feedstock mix, design, and operating conditions.
