What is Hydrodeoxygenation

This chapter discusses the management of waste cooking oil (WCO) in a sustainable manner in order to protect the environmental pollution. Increasing consumption of edible oils worldwide leads to generation of substantial amount of waste cooking oil (WCO). While WCO is not considered toxic, large amount of WCO can contribute to environment pollution if not being handled properly. The huge generation of WCO in the world creates problem of collection, treatment and disposal. Due to its chemical features, the recycling of WCO not only provides a renewable feedstock for producing biofuels and bio-based products, but also alleviates environmental pollution arising from its improper handling. This chapter also provides an overview of some recent approaches in WCO recycling and applications.
