Your Biomethane Development Pathway, VIC

Action plan

Confidence 0%

First: Validate daily manure mass and dry matter percentage through site-specific weighing.

Next: Screen the site for proximity to gas infrastructure [VIC-6] versus electrical grid capacity.

Then: Consult with EPA Victoria regarding the small-scale organic processing permission [VIC-4].

Decision gate: If the cost of gas upgrading and network connection exceeds the projected 10-year revenue of A$606,230, the project should pivot to a 'candidate route' focusing on onsite electricity and heat.

Developing this pathway in VIC

Confidence 0%

The Victorian market features 7 matching biogas pathways with 56.1 MW of published capacity. While landfill gas dominates existing records, anaerobic digestion facilities like the Lilydale hub indicate a shift toward organic waste processing.

Determine EPA permission category

• Why it matters for you: Managing manure and digestate requires specific environmental permissions under the Environment Protection Act 2017.
• Evidence needed: Expected annual tonnage and processing capacity to distinguish between A07a (large) [VIC-3] and A07b (small) [VIC-4] categories.
• Next action: Use the EPA 'Find which permission you need' tool [VIC-2] to confirm the regulatory tier.
• Who confirms it: EPA Victoria.

Define digestate management strategy

• Why it matters for you: You have a modelled 1.9 t/day of dry equivalent digestate; Victorian regulations [VIC-5] govern its application to land.
• Evidence needed: Nutrient analysis and a land application management plan (LAMP).
• Next action: Screen nearby land for its capacity to receive digestate without exceeding nutrient limits.
• Who confirms it: Certified practicing soil scientist or EPA auditor.

Project Objective and Selected Scenario

Confidence 0%

The objective is to investigate the conversion of manure from 500 fully housed dairy cows into biomethane within Victoria. You have selected a biomethane pathway yielding a modelled 441 Nm³/day (indicative gross A$60,623/yr). This output is based on theoretical yields for Collected animal manure. Alternative candidate routes include electricity (1,208 kWh/day) and recoverable CO₂ (534 kg/day). While the modelled digestate value of A$390,094/yr appears significant, it assumes a processed product price of 600 AUD/t which is not yet verified. Known factors are limited to the animal count and housing type. Assumed factors include the methane potential and the 346.75 operating days. Unknowns include the proximity to the gas network, site-specific parasitic loads, and the actual manure collection efficiency.

Commercialisation screen

Confidence 0%

Commercial viability not established. The next task is to develop a preliminary CAPEX budget for a digester and gas upgrading skid suited to this specific scale. While the modelled gross revenue for biomethane is A$60,623/yr, this does not account for the significant costs of upgrading biogas to pipeline quality or the operational expenses of manure handling. The high modelled value for digestate (A$390,094/yr) is the primary driver of the gross economics but relies on an unverified product assumption of 600 AUD/t. Without a confirmed offtake agreement for either the gas or the processed fertiliser, the project remains at a high-risk early stage. Electricity and gas connections are different infrastructure with vastly different cost profiles; the choice between them will fundamentally change the project's financial profile.

Your next pathway decisions

Confidence 0%

The current model assumes 100% collection of manure from 500 housed cows. In practice, collection rates vary by flushing or scraping frequency and bedding type.

Verify manure collection efficiency

• Why it matters for you: Your gas volume is a direct function of volatile solids captured; any loss during wash-down reduces the 441 Nm³/day output.
• Evidence needed: Daily dry matter tonnage records from the specific housing facility.
• Next action: Conduct a seven-day waste characterisation study to establish actual versus theoretical feedstock mass.
• Who confirms it: Independent agronomist or waste consultant.

Screen for feedstock contamination

• Why it matters for you: Sand or inorganic bedding can settle in digesters, reducing effective volume and increasing maintenance costs.
• Evidence needed: Physical analysis of manure samples for grit and sand content.
• Next action: Identify if current bedding is compatible with anaerobic digestion or requires pre-treatment.
• Who confirms it: Technology provider or laboratory.

Assess local use versus gas delivery

• Why it matters for you: Injecting 441 Nm³/day may incur high connection costs relative to the modest scale; local heat/power use might offer better displacement value.
• Evidence needed: Distance to the nearest gas main and current on-farm energy spend.
• Next action: Compare the cost of a network connection [VIC-6] against the cost of a behind-the-meter CHP unit.
• Who confirms it: Gas network operator (e.g. AGIG) and energy auditor.

Frequently asked questions

Can I sell the CO2 from the upgrading process immediately?

Commercial viability of CO2 sales is not established. You must first verify if the volume (534 kg/day) meets industrial quality standards and identify a buyer willing to collect at this scale.

Is the 1,208 kWh/day of electricity additional to the biomethane?

No, these are alternatives within the same gas pool. You must choose between refining the gas to biomethane or using it to generate electricity.

Does the animal count guarantee the gas volume?

No. Tonnage alone does not establish available feedstock; actual gas yield depends on collection efficiency, diet, and manure freshness.

Are certificates like LGCs or ACCUs included in the revenue?

No. Certificates and government funding are excluded from this base case; revenue is based solely on the commodity price assumptions provided.
