A waste-to-energy combined heat and power (CHP) project in the Philippines has realized substantial power and fuel savings after a year of operation, developer GE says.

The 2.8 MW plant, which came online in 2015, serves a pineapple cannery operated by food conglomerate Del Monte Philippines Inc in the city of Cagayan de Oro. Its two GE Jenbacher J420 gas engines run on biogas gleaned from treated wastewater from the pineapple production process.

The CHP plant powers the operations of the cannery and the processing plant, using the excess heat to power the boiler.

In addition to reducing its reliance on the national grid, the plant has saved Del Monte 25% in annual power consumption and 9% in annual fuel costs, as well as reducing production costs, waste and carbon emissions, GE said.

‘As our demands for reliable and secure electricity continue to grow, we considered ways to generate on-site power that would fit into the region’s strategy to reduce the carbon footprint in the Philippines while also supporting our growing investment and employment in the country,’ said Francisco T Molas, Del Monte Philippines group head for Mindanao operations.

‘The anaerobic treatment is an excellent alternative to existing aerobic systems,’ he added. ‘We can turn our biowaste into biogas to produce on-site power and heat for the cannery.’
