Republic Cement launches co-processing solution amids PH waste management crisis

Leading cement manufacturing and distribution companies ecoloop was officially released by republic cement, this project aims to help reduce the waste management of the country.


Alongside co-processing and the use of waste, like plastic or rice husk, as alternative fuels, Republic can produce cement with less dependence on fossil fuels, such as coal.

Co-processing is the reuse or recovery of the thermal and mineral properties of qualified waste materials; on the other hand manufacturing cement is a single combined operation. Co-processing remains to be a sustainable solution to the increase in the country’s waste generation that remains to be a major problem even with the Ecological Solid Waste Management Act (RA No. 9003) in place. The country has seen a continuous rise in daily waste produced over the years, from 37,000 tons in 2012 to 40,000 tons in 2016. In 2018, Metro Manila will get an average of over 9000 tons of waste per day. Whereas 85 percent of the total solid wastes were collected, 15 percent was in waterways and in bodies of water.

Alternative waste management system is much needed, Republic gets the chance to share the technology and innovation that is being used since early 2000s got bigger scope and greater nationwide impact, “Co-processing is a best alternative the manufacturing industries can and should take advantage to a long term goals of waste management as well as building the country’s foundation against climate changes with the use of sustainable practices,” say ecoloop Director Angela Edralin- Valencia.

With ecoloop, residual waste can be easily eliminated from landfills and rivers and the plastic contamination problem can also be tackled in close collaboration with producers including fast moving consumer goods (FMCG) Companies and Local government unite by collecting pre- and post- consumer waste (LGUs). Ecoloop currently has over 30 public and private partnerships throughout the country. ” As long as these wastes are considered acceptable for co-processing and acceptable under the guidelines issued by DAO 2010-6 of the Department of Environment and Natural resources (DENR), co-processing should be prioritized over other unsustainable methods of disposal that are more harmful to the environment in the long-term”, Valencia adds.

While co-processing requires the use of heat to remove waste, according to Valencia, it is distinct from the conventional method of incineration in waste management. The cement kiln co- processing method is used by Eco loop where emissions are contained and handled inside the kiln and any ash produced is completely incorporated into the stable clinker microstructure, a key cement ingredient. While some forms of incitation are dedicated for water disposal without any energy or material recovery aspects. “There is a greater risk of the release of noxious gases into the atmosphere and the by- product of ash typically always ends up in landfills”, Valencia explains.

In addition, co-processing facilitates the reuse of non- renewable sources of energy and raw materials. Heat from conventional fossil fuels such as coal and pet coke is partly replaced by the retrieved heat consent from the eligible waste. Raw materials used in cement manufacturing are also replaced by recycled minerals similar to the chemical composition of sand and clay.

Methods such as avoidance, minimization and resource recovery by recycling and reuse are also favored over co-processing in the waste management hierarchy. However, co- processing remains preferred over inefficient approaches such as incineration chemical and physical waste disposal, and landfilling when solutions are no longer available”, adds Valencia.

According to Nabil Francis, Republic is proud to play its part in providing a viable waste management solution while continuously working towards a greener and more sustainable cement production process”. Through this we are confident that moving towards a greener, stronger Republic is on the right path.”
