Hogwash oil in the making
From ifeng.com.
Hogwash oil refers to oil extracted from oily floats in the drain or leftover food from hotels or restaurants. The oil is extracted from rotten pork and peroxided oil (repeatedly used oil). It has been reported that hogwash oil has become a recycling industry chain in China.
Hotels and restaurants sell the crude waste to hogwash oil collectors after which the hogwash oil refining shops process it and sell the solid waste to pig farms as feed (these pigs are called garbage pig). Finally, the processed hogwash oil is sold to restaurants, hotels, and other eating establishments. In each step of the process, there is profitable opportunity.
The conservative estimate is 300,000 tons of kitchen garbage are produced every day from the restaurant and annual productivity is no less than 60,000,000 tons. The increasing revenue in the food industry has also indicated the garbage is avalanching in size. How much garbage has ended up as hogwash oil in restaurants? There is no exact answer.
