How we turn local waste into renewable biodiesel.
Plain language for everyday readers, technical precision where it matters. Feedstock in, B100 out — with an honest qualifier on what kinds of engines and blends it suits.
What goes in: local waste streams.
Used cooking oil
Vegetable-oil-based, post-frying. Filtered, dewatered, and tested before processing.
Spoiled vegetables
Unsellable market produce — an organic feedstock recovered from what would otherwise go to dumps.
Chicken fat
Rendered animal fat (lipid feedstock) sourced from local poultry processing.
Malabar Spinach oil
Innovative research extracting oil from alugbati (Malabar Spinach) as an alternative tropical feedstock for biodiesel.
Algae & future
Active research into algae as a high-yield, locally-grown feedstock — plus exploratory work on other organic streams.
Ten steps: from collection to community impact.
Collection of Used Cooking Oil
Pickup from hotels, restaurants, fast food chains, food courts, households, and catering services across Bacolod.
Storage & Consolidation
Collection of used cooking oil in designated containers. Recording and monitoring of volume and quality at the Green Solution.PH facility.
Quality Inspection & Testing
Removal of contaminants and water. Testing for oil quality, acidity, and impurities. Sorting of quality feedback for biodiesel production.
Pre-Treatment Process
Filtration of food particles and sediments. Heating and moisture removal. Preparation of oil for chemical conversion.
Biodiesel Production
Transesterification process — oil reacts with methanol and a catalyst to produce biodiesel (fatty acid methyl esters) and glycerol by-product.
Biodiesel Purification
Washing and refining process. Quality testing and compliance checking. Storage in biodiesel tanks for settling.
Fuel Blending & Packaging
Production of B100 biodiesel or blended biodiesel. Filling into drums, tanks, or fuel containers for delivery preparation.
Distribution to Coastal Communities
Distribution to fisherfolks, local government units, and partner organizations across Negros.
Utilization by Fisherfolks
Biodiesel used for fishing boat engines. Reduced fuel costs. Lower greenhouse gas emissions compared to imported fossil fuels.
Social, Economic & Environmental Impact
Sustainable collection and repurposing of used cooking oil. Affordable and cleaner fuel for fisherfolks. Reduced dependence on imported fossil fuels. Lower carbon emissions. Strengthened circular economy.
Lower-carbon, not zero-carbon — and honest about it.
Biodiesel made from waste feedstock is a lower-carbon renewable fuel — the carbon released when it burns was recently absorbed by the plants and animals that produced the feedstock, rather than being released from fossil reserves.
We do not claim net-zero or zero-emission operation. There is still energy used in collection, processing, and distribution. The honest framing is: a lower-carbon alternative to fossil diesel, for engines that can run it well.
Specific carbon-reduction figures are model-dependent and feedstock-dependent — we do not publish a single headline number on this site.
DTI Shared Service Facility.
UCO Filtration Machine
Multipurpose filtration system for removing contaminants, water, and impurities from collected used cooking oil.
Biodiesel Brewing Machine
Core reactor for the transesterification process — converting filtered oil into fatty acid methyl esters (biodiesel).
Storage & Safety Systems
1,000-liter storage tanks, conical transparent tanks for settling, chemical containers, and methanol safety tanks for safe operations.
