MANILA, Philippines — Globally, around 4.8 to 12.7 million tons of plastic wastes enter the oceans every year according to an article published by the World Bank 2021. The same article revealed that 40-50% of these marine plastic wastes are single-use consumer packaging and 80% of the global plastic wastes leaking into the ocean comes from Asia. In fact, the Philippines is the third largest contributor of marine plastic waste with over 750,000 tons of plastics entering the ocean annually.
To combat marine plastic pollution, a social innovation enterprise is working tirelessly in coastal areas in Batangas and Davao to promote and implement sustainable solutions that reduce marine plastic litter and transform residents into active agents of marine conservation.
Led by its founder and CEO, Pia Roxas Ocampo, Pure Oceans is making significant impact in coastal municipalities of Mabini and Tingloy, Batangas and Samal Island, Davao by working closely with the locals and fisherfolks to take out plastic wastes from coastal waters and beaches.
“Pure Oceans works with coastal communities that must live amidst tons of plastic waste brought from wealthier cities or municipalities by the currents, waves and wind. We help the communities develop, prototype, test and sustain plastic waste solutions that allow them to live healthier and more dignified lives despite this plastic crisis that impacts them directly,” Pure Oceans founder Pia Roxas Ocampo shares.
Republic Cement, through ecoloop, its official resource recovery group, partnered with Pure Oceans in diverting non-recyclable and single-use plastic wastes collected from coastal waters and shores to a more viable and sustainable disposal method called cement kiln co-processing.
Co-processing involves the reuse or recovery of thermal and mineral properties of qualified waste materials, such as residual plastic or rice husk, as alternative fuels for cement manufacturing.
“Co-processing is preferred over other unsustainable disposal methods such as incineration and physical/chemical treatment,” shared ecoloop Director Atty. Angela Edralin-Valencia. “The by-products of these two disposal methods, i.e. ashes and treated wastes, would eventually end up in landfills. In contrast, co-processing, which optimally operates at 1,450 degrees Celsius, destroys residual waste completely; hence, no residual by-products such as ash is produced. Noxious gas emissions are controlled within the combustion chamber through gas and material counter flow.”
Republic Cement is the pioneer of using alternative fuels in the cement manufacturing process in the country, having over 20 years of co-processing experience. By using alternative fuels in the manufacture of cement, Republic Cement is able to reduce dependence on fossil fuels, such as coal. Republic Cement’s plants are equipped with baghouse filters and electrostatic precipitators as well as state-of-the-art Continuous Emission Monitoring Systems (CEMS) to ensure strict compliance with emissions and environmental standards.
Since 2020, Pure Oceans has diverted an equivalent to 1.93 million sachets of waste to co-processing. Republic Cement also further incentivized Pure Oceans and the Tingloy LGU to collect and segregate trash by offering cement in exchange for qualified plastic wastes. The exchanged residual plastic waste was used by Pure Oceans and the Tingloy LGU as supplementary for the reconstruction of the beachfront walkway in a small barangay damaged by Typhoon Quinta back in 2020.
