As waste, UCO should be collected and managed in an environmentally sound manner.

One of the primary uses for UCO is in the production of biodiesel.

Compared to biodiesel made from vegetable oils (such as soy, sunflower, corn, or palm oil), biodiesel from UCO is more environmentally friendly.

This is an efficient practice that can help to reduce waste and support the development of sustainable energy sources. 

Animal Fat

Fat from animals that are not intended for human consumption 

This can include fat from innards that come from slaughterhouses and cutting plants. 

Inedible animal fat can be repurposed and used in a variety of applications, including soap and detergents, cosmetics, candles, lubricants, and biodiesel.

Acid Oil

Acid oil is a waste from vegetable oil refining plants. 

This waste either comes from a winterized cake, soap stock, or scrubber fatty acid 

Applications for acid oil include animal feed, biodiesel production, soap detergents production, lubricants, and chemicals. 


Methyl ester, also known as fatty acid methyl ester (FAME), is a type of biodiesel that is produced from the transesterification of fats, oils, and grease (FOG). 

The resulting methyl ester can be used as a renewable fuel source in diesel engines, and can also be used in other applications, including heating and power generation, transportation, solvents, personal care products, and lubricants. 

Brown Grease

Brown grease is a waste product of the food service sector that is often collected from grease traps, which are tools meant to stop grease and other materials from entering the municipal wastewater system.

In contrast to yellow grease, which is gathered from fryers and grills (UCO), brown grease is made up of a combination of fats, oils, and grease (FOG)

Brown grease can be recycled and applied to a few different things i.e., biodiesel, fertilizer, and industrial applications.
