In recent years, we have explored means to further reduce greenhouse gas emissions related to the palm oil production process. In 2017, Neste-led collaborative project verified that adoption of a belt filter press method in wastewater treatment at palm oil mills can reduce or prevent methane emissions by 50% compared to emissions from the mill's conventional open pond method. The project was conducted in collaboration with a palm oil company KLK, a Dutch sustainable trade organization IDH, and International Sustainability and Carbon Certification certification system (ISCC).
Research article on the method’s emission reduction potential was published in May 2018. The method is referred to by e.g. certifying body ISCC and recognized in relevant certification systems. Companies using the belt press method can apply a new emission factor in their greenhouse gas calculations for certification purposes.
We continue to help accelerate implementation of the developed method within the palm oil industry by connecting interested parties with the technology provider. Wide-scale implementation of the method could provide large climate impact, up to 4.5 Mt CO2e per year, equivalent to removing 1.6 million passenger cars from the roads.
We will be promoting and driving the implementation of methane reduction opportunities for years to come, supporting our handprint target of 2030 and footprint of 2035.
