Cooking Oil Recycling


Many bars, restaurants, hotels and homes still throw the cooking oil directly into the sewage system, unaware of the damage of this action. Regardless of destination, this product harms the soil, water, air and life of many animals, including humans.

When trapped in the pipeline, the oil causes clogging of the pipes and requires the application of various chemicals for their removal. If there is no sewage treatment system, the oil eventually spreads to the surface of rivers and dams, contaminating the water and killing many species that live in these habitats.

Data indicate that with one liter of oil it is possible to contaminate one million liters of water. If it ends up in the soil, the liquid can waterproof it, which contributes to flooding and flooding. In addition, when it goes into a decomposition process, the oil releases methane gas that, in addition to the bad smell, aggravates the greenhouse effect.

Correct oil discharge

To prevent waste cooking oil from being discharged into the sewage system, cities, institutions and people around the world have created methods for recycling the product. The possibilities are many: resin production for paints, soap, detergent, glycerin, animal feed and even biodiesel.

This type of fuel is already being widely developed around the world. Here in Brazil, the United Nations Environment Program (UNEP) in partnership with Bayer has awarded a research by the University of São Paulo (USP) on biofuel production from cooking oil. The award took place in 2007, during the Young Environmental Ambassadors project.

The Biodiesel project at home and in schools also has the participation of university students, schools and companies that have already helped collect more than 100 tons of cooking oil to be made into 100% renewable fuel.

Process

Biodiesel - The transformation of cooking oil into renewable energy begins with filtration, which removes all the waste left by the frying. Then all water mixed with the product is removed. Depending on the oil, it will undergo a chemical purification that will remove the last residues. This "clean" oil then receives the addition of alcohol and a catalyst substance. Placed in the reactor and stirred at specific temperatures, it turns into biofuel and after refining can be used in engines capable of burning it.

Soap - To make bars of soap from cooking oil, just follow the recipe below:

Materials:

  • 5 liters of used cooking oil
  • 2 liters of water
  • 200 milliliters of fabric softener
  • 1 pound of scale caustic soda

Preparation:

  1. Carefully place the scaled soda into the bottom of a bucket.
  2. Then put the boiling water.
  3. Stir until all the soda scales are diluted.
  4. Add the oil and stir.
  5. Add the fabric softener and stir again.
  6. Throw the mixture into a pan and wait for it to dry.
  7. Cut the soap into bars.

Attention: Caustic soda can cause skin burns. Ideally, use gloves or wooden or plastic utensils to prepare the mixture.

Other types of solutions may be used to prevent oil from being discharged into sewers. A product developed in Spain promises to solidify the oil and facilitate its storage, collection and recycling. Christened of Fried Fried, the product should be thrown into the still hot oil and after a few minutes all the liquid will be solid. Just remove from the frying pan and store.

If this solution is too far from you, simply store the leftover frying in a PET bottle and deliver it to a collection point.

Where to donate your used cooking oil

In some Brazilian capitals it is the municipalities that are mobilizing, in others it is the population itself through non-governmental organizations.
Ribeirão Preto: owns the Cata oil project in a partnership between USP and Ladetel (Clean Technologies Development Laboratory). Interested parties receive a container to store the oil. The lab truck passes by collecting the product at pre-set dates.

All oil collected in the city will be used to produce biodiesel. Today about 20 thousand liters of oil are collected per month from traders, however, the interest is to reach the population and receive about 160 thousand liters monthly.
Information: Those interested in participating in the project may contact Ladetel at (16) 602.3734.

Curitiba: Curitiba City Hall launched the special collection of frying oil service. The collection is being made at 78 Green Exchange points (recyclable garbage collection program) and at the city's 21 bus terminals. When delivery is made at these stations, two liters of oil entitle one kilogram of fresh produce, further encouraging the population.
Once collected, the frying oil is sent for recycling, where it is transformed into soap, detergent and raw material for the manufacture of other products.
To be delivered, the oil must be stored in pet bottles, preferably transparent.
Information: The days and times of the collection can be obtained by calling 156 or on the City Hall website - www.curitiba.pr.gov.br

ABC Paulista: Instituto Triangulo has been an example of cooking oil recycling in São Paulo. Teams go to the requested collection site, as long as there is a minimum of six liters to request receipt. The oil can be delivered to São Paulo at the Pão de Açúcar supermarket chain or at Ong Trevo and Samorcc (Society of Friends and Residents of the Cerqueira César Neighborhood).
Information: Triangle Institute (11) 4991-1112 - www.triangulo.org.br

Florianópolis: The collection is made by the Federal University of Santa Catarina, which, since last year, has been developing the project called the Casca Familia, in which it recovers cooking oil and turns it into fuel. However, the project collects the product only in the region near the university.
Another useful end to the oil in bars and restaurants in the city is through the Florianópolis Industrial and Commercial Association, Acif, which runs the ReÓleo program.

Rio de Janeiro: the oil that would be thrown can be taken to the stations implemented by the Vegetable Oils Reuse Program, Prove, signed between the private initiative, the Manguinhos Refinery and the Rio de Janeiro Environment Secretariat. Flying. Another way to collaborate is to call Dial-Oil: just get in touch with the program staff to visit your home

Savior: chemical engineer Luciano Hocevar is responsible for Renove, Recycling Vegetable Oils, and for the pickup truck that passes through town houses collecting cooking oil.
Information: (71) 9979-2504 - www.renoveoleo.com.br

Porto Alegre: Porto Alegre City Hall, through the Municipal Department of Urban Cleaning (DMLU), conducts the Frying Oil Recycling Project. There are 24 collection sites for the product, which will be transformed among other things into paint resin, soap and biodiesel. An agreement was signed between DMLU and three companies that will collect cooking oils delivered by the population and send them for recycling.

The success of these cooking oil recycling programs depends entirely on community participation. All of these collection programs, whether governmental or non-governmental, provide all the information necessary for oil recycling and also clarification on environmental protection, precisely to place society in ecological responsibility.
