Marikina City uses cooking oil to make eco bricks

Published Jul 15, 2022 04:45 pm

As the City of Marikina continues to innovate projects for its waste management initiatives, the local government began collecting used cooking oil from residents, which they mix with plastic materials to create eco bricks.

In an interview with DZBB on Friday, July 15, Mayor Marcelino "Marcy" Teodoro noted that there is a big amount of wasted cooking oil that end up clogging the drainage systems when disposed of in sinks or even toilets. 

To prevent damage to their systems, the local government devised a method of collecting used cooking oil from residential areas, as well as restaurants and other establishments in the city. 

There are designated collectors from the City Environmental Management Office (CEMO), and some from the private sector, that follow a particular schedule per barangay.

The collectors roam around in a vehicle carrying a drum where residents can store their used cooking oil. 

"Pag nakolekta ito, nire-recycle natin. Ginagamit natin ito kasama ng ibang recyclable materials katulad ng Styrofoam, at mga tarpaulin at campaign materials. Shine-shred, pinapakuluan 'yung mantika tapos meron tayong ginagamit, tawag styro-plastic densifier machine (When we've collected the oil, we recycle them with the other materials like Styrofoam, and the taurpalins and other campaign materials. We shred the plastic, then put them to boil with the cooking oil. Afterwards we place them inside a styro-plastic densifier machine)," Teodoro explained.

The mayor said the densifier machine was given to the local government from a grant by the Department of Science and Technology (DOST). 

They crafted a proposal on recycling, which they presented to the DOST, as a component for their Materials Recovery Facility (MRF), Teodoro said. 

The initiative also served as their compliance to the national solid waste management policy. 

The local government uses the eco bricks for landscaping projects, flooring and creating pavements for school grounds, parks, and playgrounds. 

Aside from this, CEMO is also exploring options to create other molds in which to pour the liquified materials once they've been densified.

Teodoro said CEMO is now making molds to turn the materials into pots for plants.

The eco bricks are durable due to the fibers that make up the recycled plastic materials. The machine also densifies the bricks to make them more compact.

Teodoro said they are exploring other options and uses for the eco bricks such as offering the them to residents for their personal use, especially through the Home Materials Assistance Program. 

They will also consider working with other local government units if the oil collection project can be feasible.
