One of the technologies highlighted in the TNA is waste heat recovery systems. This is an approach to improving overall energy efficiency, as it captures and reuses the lost or “wasted heat”. Based on the Lafarge Teresa Plant in the Philippines, which already uses this technology, it is estimated that introducing similar plants employing waste heat recovery systems would reduce CO2 emissions by around 11,800 tonnes yearly.
Located in Southeast Asia, the Philippines is a cluster of islands surrounded by the South China Sea, the Philippine Sea and the Celebes Sea. Being an archipelagic country, the Philippines is highly vulnerable to the impacts of climate change and natural hazards. Important economic sectors such as agriculture, fisheries and water management are all particularly exposed to the consequences of climate change.
The Philippines completed the first stage of its TNA in 2018. The TNA follows the Philippines’ NDC in terms of overall sector prioritization, but in some instances it prioritizes new technologies that are not included in the NDC. During the TNA process, the relevant stakeholders agreed to add biogas to the list of possible technologies in the transport sector. Biogas was subsequently chosen as a priority technology due to its mitigation potential and its link to both the transport and waste sectors. As a part of an integrated waste-management system, biogas produced from anaerobic digestion reduces emissions of landfill gas into the atmosphere, while the utilization of waste and residues reduces ecological damage and closes material cycles.
Philippines’s TNA contributes to the following Sustainable Development Goals:
