Philippine president Rodrigo Duterte has reportedly promised investment of P300m ($6.4m) for biomass power projects after inaugurating a new plant in Maguindanao province on Friday.

The 4.5 MW Buluan Biomass Power Plant, developed by the local government in co-operation with the Green Earth Enersource Corporation of China, is now online. Duterte’s visit included a plant tour and a speech to local officials.

According to newspaper the Manila Bulletin, Duterte was impressed by the plant’s use of palm oil by-products as fuel – a first for the country – and subsequently ordered his agriculture department to release the funds immediately to support further such projects.

The report said most of the money is expected be used to expand the capacity of the Buluan plant.
