Labl Farms
County- and crop-specific farmer engagement, agronomy and responsible production.
Crostar Energy pathway
From responsible feedstock to qualified renewable fuel.
Crostar Energy leads the technical and commercial biodiesel pathway. Labl Farms supports approved farmer-facing agriculture, while the Labl digital system can connect consented field, lot, quality and custody records.
Clear accountability
Specialist roles across one traceable pathway.
Crostar Energy is responsible for feedstock qualification, used-cooking-oil collection, processing design, technical and commercial feasibility, fuel quality, safety, environmental compliance and market development. Labl Farms leads any approved oilseed farmer engagement and agronomic research. Shared records may be supported by the Labl digital operating system.
Labl digital system
Permissioned records for participants, plots, lots, custody, quality and transactions.
Crostar Energy
Feedstock aggregation, extraction, conversion feasibility, standards, safety and biodiesel markets.
Qualified market
Domestic, regional or export route only after approvals, specifications and viable economics.
Potential inputs
Diversified feedstocks, tested responsibly.
No crop or waste stream is automatically sustainable. Every route must protect food security, land and water rights, biodiversity, farmer economics and legal compliance.
Cottonseed
A ginning co-product with potential oil value where quality, volumes and economics are viable.
Castor and jatropha
Non-food oilseed options requiring local agronomic, toxicity, handling and land-use assessment.
Canola and croton
Potential feedstocks subject to suitability, yield, market and environmental evidence.
Used cooking oil
A complementary waste-recovery stream requiring lawful collection, contamination control and custody records.
The process
A gated route from source to sale.
Each stage must pass technical, environmental, social, safety, legal and commercial checks. Progress at one stage does not guarantee approval of the next.
Screen
Assess crop or waste-stream origin, land and food-security risk, expected volume, contamination, economics and legal route.
Produce or collect
Use approved agronomy for oilseeds or controlled collection agreements for used cooking oil, with consent and source records.
Aggregate
Receive, weigh, identify, inspect and segregate lots; record custody, supplier, location, date and basic quality information.
Prepare
Clean and condition seed or pre-treat recovered oil. Reject unsuitable, unsafe or untraceable material.
Extract and recover
Use appropriate mechanical or approved extraction systems for oilseeds; manage press cake and other co-products safely.
Characterise
Laboratory-test key oil properties and contaminants to determine whether the feedstock is suitable for a validated conversion route.
Convert
Under engineered controls, convert qualified oils through the selected biodiesel process, commonly transesterification, producing biodiesel and a glycerol-rich co-product.
Purify
Separate, recover and responsibly manage process inputs and co-products; wash or polish and dry the fuel as required by the validated design.
Verify
Test the finished fuel against the specification required for its intended market, blend and use. Non-conforming product is isolated.
Store and distribute
Use approved tanks, labelling, fire controls, transport, records and licensed market channels; retain batch and customer evidence.
Decision gates
Evidence before expansion.
The pathway is designed to prevent premature scale, unverified sustainability claims and unsafe or non-compliant production.
01AgronomyCrop suitability, yield stability, soil and water impact, farmer net benefit and non-displacement of food.
02FeedstockTraceable origin, sufficient volume, acceptable quality, safe handling and viable delivered cost.
03EngineeringMass balance, process control, energy and water demand, equipment integrity and competent operators.
04EnvironmentRequired assessment and licensing, waste and emissions controls, spill prevention and emergency readiness.
05Fuel qualityIndependent or competent laboratory results against the destination-market specification.
06MarketQualified buyer, lawful blending or sale route, logistics, pricing, insurance and enforceable contracts.
Responsible delivery
Safeguards are part of the business model.
Renewable origin alone does not make a fuel responsible. The programme must evaluate the full route, including unintended impacts and who carries the risk.
Land and food
No automatic conversion of food land; use documented land rights, crop suitability and food-security checks.
Farmers and workers
Clear terms, transparent weights and prices, safe handling, training, protective equipment and grievance routes.
Biodiversity and water
Avoid sensitive ecosystems, measure water needs and use locally appropriate soil and biodiversity safeguards.
Chemicals and fire
Engineered storage, competent supervision, separation, ventilation, spill response and emergency systems.
Waste and co-products
Define lawful, safe and commercially credible uses or disposal routes before production.
Claims and carbon
Make climate or sustainability claims only from a documented boundary, credible data and appropriate verification.
Ways to participate
Build one part of the pathway well.
Potential collaborators include agronomists, farmer organisations, waste-oil aggregators, laboratories, equipment providers, safety specialists, universities, county institutions, financiers, fuel buyers, logistics providers and traceability partners.
