WCO / UCO
Waste Cooking Oil (WCO) / Used Cooking Oil (UCO) as Feedstocks
What is Waste Cooking Oil (WCO) / Used Cooking Oil (UCO) ?
Waste Cooking Oil (WCO), also known as Used Cooking Oil (UCO), refers to animals and vegetable-based oils that have been used for frying or cooking food and are no longer suitable for consumption.
Used Cooking Oil (UCO) is emerging as a powerful resource in the global push toward sustainability. Once discarded as waste, it now plays a vital role in producing renewable fuels and other eco-friendly products.
Saybolt Singapore provides industry-leading analytical testing to ensure that WCO/UCO meet the strict requirements for conversion into biodiesel, Sustainable Aviation Fuel (SAF), and Hydrotreated Vegetable Oil (HVO). Our laboratories assess a broad spectrum of chemical, physical, and contaminant properties vital for process efficiency, fuel quality, and regulatory compliance.
