Technology

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.

Feedstock

What goes in: local waste streams.

Restaurants & households

Used cooking oil

Vegetable-oil-based, post-frying. Filtered, dewatered, and tested before processing.

Public markets

Spoiled vegetables

Unsellable market produce — an organic feedstock recovered from what would otherwise go to dumps.

Poultry processors

Chicken fat

Rendered animal fat (lipid feedstock) sourced from local poultry processing.

R&D · Visayas crop

Malabar Spinach oil

Innovative research extracting oil from alugbati (Malabar Spinach) as an alternative tropical feedstock for biodiesel.

R&D

Algae & future

Active research into algae as a high-yield, locally-grown feedstock — plus exploratory work on other organic streams.

The process

Ten steps: from collection to community impact.

01 · Collect

Collection of Used Cooking Oil

Pickup from hotels, restaurants, fast food chains, food courts, households, and catering services across Bacolod.

02 · Store

Storage & Consolidation

Collection of used cooking oil in designated containers. Recording and monitoring of volume and quality at the Green Solution.PH facility.

03 · Inspect

Quality Inspection & Testing

Removal of contaminants and water. Testing for oil quality, acidity, and impurities. Sorting of quality feedback for biodiesel production.

04 · Pre-treat

Pre-Treatment Process

Filtration of food particles and sediments. Heating and moisture removal. Preparation of oil for chemical conversion.

05 · React

Biodiesel Production

Transesterification process — oil reacts with methanol and a catalyst to produce biodiesel (fatty acid methyl esters) and glycerol by-product.

06 · Purify

Biodiesel Purification

Washing and refining process. Quality testing and compliance checking. Storage in biodiesel tanks for settling.

07 · Blend

Fuel Blending & Packaging

Production of B100 biodiesel or blended biodiesel. Filling into drums, tanks, or fuel containers for delivery preparation.

08 · Distribute

Distribution to Coastal Communities

Distribution to fisherfolks, local government units, and partner organizations across Negros.

09 · Utilize

Utilization by Fisherfolks

Biodiesel used for fishing boat engines. Reduced fuel costs. Lower greenhouse gas emissions compared to imported fossil fuels.

10 · Impact

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.

Environmental framing

Lower-carbon, not zero-carbon — and honest about it.

What that means

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.

Compatibility & blend. B100 (100% biodiesel) is not a drop-in replacement for every diesel application. Older engines, certain fuel-system materials, and very cold climates may require a blend (e.g. B5–B20) or engine modifications. All claims on this site refer to compatible diesel applications, subject to blend and engine requirements. We help partners qualify suitability before any production-volume supply.
Facility & equipment

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.
