Used Cooking Oils

Used Cooking Oils (UCOs) are oils and fats that have been used for cooking or frying in the food processing industry, restaurants, fast foods and at the consumer level, in households. The European Waste Catalogue (EWC) classifies them as Municipal Wastes (household waste and similar commercial, industrial and institutional wastes) including separately collected fractions, under the code 20 01 25 (edible oils and fats). UCO obtained from wastewater treatment plants is also considered non‐hazardous materials with a different code: 19 08 09 (grease and oil mixture from oil/water separation containing edible oil and fats).

Collection and wholesale supply of waste oil for meeting the needs of Biodiesel plants are the primary missions of ZIMKER KFT. Its professional specialties and teams play an essential role: matching waste oil product supply with demand, day in and day out, on a global scale. As a result, we have access to widely diversified sources of supply and substantial resources.

Our trading teams have forged close, long-term relationships with a network of customers and suppliers worldwide, including national and international oil companies and all producers, refiners, traders, brokers, and distributors.

ZIMKER KFT is one of the largest waste cooking oil collectors in the whole of Europe.

Our Used Cooking Oils (UCOs) collected is for reselling purpose to Biodiesel industries. We can partners with major worldwide biodiesel plants for supplying millions of gallons on contracts.

UCO collection, transport, and storage
The ZIMKER KFT has identified three main UCO collection strategies:

  1. Processor Decentralized collection: Our company sets up a door to door collecting system in order to collect directly from the “producers” of UCO.
  2. Processor Centralized collection: The “producers” of UCO deliver it at centralized collection points. Our company collects them directly from these locations.
  3. Combined Supplied Collection: Our company supplies the raw vegetable oils to the “producers” of UCO and collects them for recycling as well.

QUALITY CHARACTERISTICS OF THE COLLECTED UCO USED FOR PROCESSING TO BIODIESEL:

Physical and chemical properties of UCO :

UCO contains impurities, such as Free Fatty Acid (FFA) and water, which have to be removed before the transesterification process. In fact, FFAs react with the alkaline catalyst to produce soap, which inhibits the reaction resulting in a poor biodiesel yield (Leung & Guo, 2006; Banerjee & Chakraborty, 2009).
