Recycling Used Cooking Oil




Bad disposing of the Used Cooking Oil is Anti-Ecological!

Nowadays society increasingly takes greater awareness of sustainable development and the need to produce the least amount of waste, which has a negative effect on the ecology of our planet. The Used Cooking Oil waste is the leading cause of urban water pollution, due to uncontrolled dumping. This happens because once poured down the drain, these residues cause problems in the sewage of our cities, causing blockages, odors and pests in the plumbing systems.

The negative consequences of pouring the UCO in the drain are:

  • Important environmental aggression.

Once in the rivers or in the sea, the used cooking oil alters the balance of oxygen and water, as it creates a film difficult to eliminate that prevents the passage of light and the exchange of oxygen between air and water, disrupting the aquatic ecosystems, endangering many species of animals and plants.


  • Increases the difficulty and threatening cost in wastewater treatment plants.
As it is known, before returning to rivers and seas, all the water flowing in the drainage of the cities goes through a wastewater treatment plant that separates solids and impurities the water has. The problem of draining the used cooking oil  in the sink  is that it is very difficult to separate from water in the treatment plants, unlike the solid particles that can be removed by a simple filter or other impurities that are removed by microorganisms with ozone, ultraviolet rays and  hydrochloric acid treatments. Currently there is no effective process that separates the UCO from water. Besides, the UCO can lead to various problems in the wastewater treatment plants, such as breakdowns, costly obstructions and reduction of the plant’s life, causing an increase of the energetic and economic cost of processing the water.


  • Limitation on wastewater reuse.

One liter of oil contaminates 1.000 liters of water , in addition it  multiples times 10 the cost of treatment.


  • High sewage systems maintenance cost.

Discharges of Used cooking oil solidify causing blockage and pipe corrosion, which are the cause of bad odors.  They are also responsible for increasing urban pest.

Therefore the solution to this serious problem is: to recycle Used Cooking Oil.  This would bring the following benefits:


  • Elimination of a highly pollutant water waste.
  • Cheaper cost and facilitation of the work invested by wastewater treatment plants.
  • Reuse of treated water.
  • Reduced degradation and obstruction of sewage systems.
  • Decreased probability of overgrowth of harmful microorganisms that cause bad odors and health problems.


All of this makes the recycling of this material a very important issue. The collected used cooking oil can be recycled and reused as raw material for different materials and products such as:  lubricants, soaps, candles, cosmetics, paints and varnishes, biodiesel, organic fertilizer and as an additive for animal feed. This is how that the recycling of the Used Cooking Oil contributes in a great way to the preservation of the environment.
