Making of roads and cement with Plastic Garbage in Philippine

Philippine companies like San Miguel Corp. and Aboitiz Equity Ventures Inc. are using discarded shopping bags, sachet wrappers and plastic packaging to fire cement plants and build roads as the country embarks on an 8 trillion-peso ($157 billion) infrastructure push through 2022.

Making of roads and cement with Plastic Garbage in PhilippineSan Miguel has laid down its first road combining plastic scraps with asphalt, it said in November. The surface material, developed with Dow Chemical Co., used 900 kilograms (1,984 pounds) of plastic to pave a 1,500-square meter (16,145-square foot) test site near the capital.

For Aboitiz’s Republic Cement & Building Materials Inc., plastic serves as an alternative to coal for heating kilns used in making cement. The company is sourcing waste from consumer giants like Nestlé Philippine Inc. and Unilever Philippines Inc. as it processes at least 25,000 tons of plastic annually, director Angela Edralin-Valencia said in an interview.

The two initiatives target soft plastics that are hard to recycle and make up a significant chunk of the trash piling up in Philippine landfills and clogging waterways.
