Uses of Waste Vegetable Oil (WVO)
Waste vegetable oil (WVO) is a valuable resource with a wide range of uses across multiple industries. This page explores the many ways WVO is repurposed to support sustainability, power generation, and eco-friendly products.

One of the most impactful uses of WVO is in the production of biofuels. It is converted into biodiesel through transesterification and can also be used in the production of hydrotreated vegetable oil (HVO), a renewable diesel substitute. These fuels help reduce greenhouse gas emissions and reliance on fossil fuels.
In biomass energy, WVO can also be burned to produce heat and electricity for off-grid or industrial systems.
2. Engines and Transportation
Filtered WVO or its biodiesel form can be used to power diesel engines in vehicles, agricultural equipment, and commercial fleets. Modifications may be needed to ensure efficient combustion and reduce emissions. Biodiesel from WVO is compatible with many existing engines and fuel systems.
Backup generators, particularly in data centres and rural sites, are now using HVO from WVO as a cleaner fuel source.

Through the saponification process, WVO is turned into natural soap by reacting it with lye. These soaps are used in household cleaning, hand washing, and even laundry. In industrial settings, WVO is repurposed to create degreasers and eco-friendly surface cleaners.
These products reduce the use of petroleum-based chemicals and help prevent WVO from entering drainage systems.

WVO is used in the production of biodegradable lubricants and hydraulic fluids for machinery. It's also a source of oleochemicals used in coatings, emulsions, and paint products. The processing of WVO yields glycerin and fatty acids that are useful in a variety of chemical formulations.
5. Power Generation
Some businesses and facilities use WVO to fuel generators for sustainable, off-grid electricity. Data centres such as Kao Data have adopted HVO derived from WVO to reduce carbon output. Farms, event organisers, and remote facilities also use biofuel-powered generators as part of their sustainability strategy.
6. Cosmetics and Personal Care
WVO can be refined into ingredients used in moisturisers, hand creams, lip balms, and soaps. The extracted glycerol and fatty acids provide hydration and consistency in many skincare products. As the demand grows for natural and zero-waste products, WVO is increasingly seen as a valuable cosmetic base.
7. Environmental Sustainability
Recycling WVO helps reduce greenhouse gas emissions, lowers dependence on virgin oil sources, and diverts waste from landfills. It supports a circular economy by turning a common waste product into new energy and materials. Proper collection and reuse of WVO prevents blockages in drains and contamination of water systems.
8. Business and Compliance Benefits
Businesses that partner with licensed collectors ensure legal compliance with waste regulations. Collection services provide necessary transfer documentation and help businesses meet environmental goals. WVO collection also reduces the risk of improper disposal and can lower operational waste costs.
